THREADLY REMINDER THAT FAPPING IS THE ULTIMATE DEMOTIVATOR

>>15244722

ironic, I want to make somethinig fap worthy, sometimes it means I am horny while working on it.

>>15244722

>he doesn't fap to his code to get an extra dopamine rush associated with progress

>>15244853

Still, what are your tools in that regard?

Need coding help for Godot Engine. Maybe not the best place to ask, but I'll ask here anyway:

I'm doing Game Programming Academy's 3D tactics movement method (embed related) since it would let me arbitrarily extend a tactics scenario vertically, but I'm adapting it to Godot's codebase as possible as I don't want to deal with Unity's weak render code on my underpowered laptop. I've got most of the basics figured out but with a single rather large snag

The problem starts at around 22:00 in the video, where he uses Physics.OverlapBox to create a box that checks for tiles you can move or jump to (using an extents value you can feed to it to determine the height it should check). Specifically the problem is that Godot does not have a Physics.OverlapBox command, nor similar as I could find.

I want to cast a RayShape box to substitute for the OverlapBox, return all hit objects, check their group/tag, and send a command if it matches expectations, but there are precisely zero tutorials on the entire internet on how to properly cast a RayShape (plenty of people bitching that they can't get one to work though)

Help? Alternative suggestions with code examples?

>>15244936

Looks good, the mistake I see even in "professional" works with expressions is how sometimes they overdo it.

>>15244962

Can you elaborate? What do you mean they overdo it? They have totally different requirements and circumstances. This is just using blendshapes, professionals use many bones and small expression changers because they sometimes also have to deal with mocap.

>>15245033

I don't think we are on the same page. I am using a model optimized for games. Meaning grouped up very generalized blendshapes like "smile" are not in my model because overall it would add more overhead from the more blendshapes. (Mine is just named smile but really it's a blendshape only for the zygomaticus). With a set of specific muscle blendshapes I can combine, transition, and make many more expressions better than a bunch of generalized expression sliders. DAZ probably doesn't have realtime in mind so they can do whatever they want and have 100 different generalized expression sliders.

>>15245065

What I mean is, with the sliders you have you can do better stuff than those pre-baked expressions, you just need to save them not as new blendshapes per se, you can just make driven keys that you can use to save some time.

Drunk programmming is the best!

Tried out a bunch of guitar VSTs and plugins, and all of them sound like cancer shit, even the "professional" ones.

Tried some other techniques, though, and I think I improved it somewhat.

https://files.catbox.moe/xqt8om.mp3

Anything else I can do to improve it somewhat?

Any C developer can give me some advice?

I just started making this game, never made a game before, really, only messing around

Anyway, I have a struct called entity and it holds a void* and 4 function poiinters for initializing, deinitalizing, updating and drawing, and I'm planning to just make pretty much everything an entity, from game states to enemies to the player, and casting the void* to the right data structure for that type of entity in the callback functions.

Is this considered bad design? Please don't just say use C++. I can't think of another way to really do a game in C without this sort of method.

>>15245743

It is bad design, you are designing your code around not being aware of the type anything has, and just typing it as an entity struct. Why can't you just pass your structs into functions while being aware of the type? It's going to be very bad writing a one-size-fits-all struct for your entire program. Just write specialized structs and functions for the tasks. Write it in a way where you are aware of the types. Don't just force everything into one "entity" type.

>>15245769

I did it because I didn't know how to have a state system without having the anonymous pointer for the states data. I have my loop just call the update/draw function of the current state atm so that I can just change easily.

Like I said never done a game before, so I'm pretty in the dark for this type of thing. I mean, if I keep on top of what I'm passing where it doesn't seem to bad.

>>15244722

No it's not. It's just an addictive procrastination method. And procrastination should be avoided whenever possible.

>>15245138

Either way the goal is to not bloat the scene with active nodes but instead run checks on command. Wherever the start box is, it cascades outward, activating nodes within it's range while iteratively reducing a distance left variable. Making multiple rayshape nodes would require excessive coding as well (though I admit it might be the most effective solution)

Instancing a collision box node would have it's own problems too. The checks occur every movementt phase, so I'd have to properly destroy each new node after returning collision

Thanks for the input though.

Any other suggestions?

>>15245853

Use specialized structs and specialized functions for every class of "thing" in your program. That should make the code a lot better, even if you have to give up on having one function that loops through every resource.

>>15245914

last time i checked godot had no trouble keeping track of millions of static colliders, however it had framerate issues moving around 50-ish kinematic bodies or 20-ish physic bodies

>>15245743

>I can't think of another way to really do a game in C without this sort of method.

Have you tried just using a "type" variable and switch()'ing off of that?

typedef enum entityType {
    ENTITY_TYPE_RAD_LAD,
    ENTITY_TYPE_SHITPOST,
    ENTITY_TYPE_SHITPOST_MAXIMUS,
} entityType;
typedef struct entity {
    entityType type;
    float x,y,z,w,a,b,c;
} entity;
void entityRender(const entity* e) {
    switch(e->type) {
        case ENTITY_TYPE_RAD_LAD:
            // render the raddest of lads
            break;
        case ENTITY_TYPE_SHITPOST:
        case ENTITY_TYPE_SHITPOST_MAXIMUS:
            // render shitpost or shitpost maximus: they use the same render code
            break;
    } // No default case; this way our compiler warns us if we forgot a type.
}

The downside is that you'll end up with rather large & more complex objects.

I think the question you need to ask yourself is: "Do I really need to create different data structures for different entity types?". You'll often be reusing tons of code between entities anyway, so why not keep it all in the same place instead of copy-pasting it about?

If you want more meaningful advice, talk about the game you want to make, rather than pure code.

>Please don't just say use C++.

It's worth knowing what C++ does under the hood, though.

Instead of storing all the function pointers inside of the object, it stores a single pointer to a vtable, which contains all the function pointers. This makes objects smaller, is less error prone in general, vtable pointer & vtable itself can be entirely const to help the compiler optimizations, allows you to retrieve the type of the object by looking at the vtable address, and is also pretty much required if you want to have sane inheritance.

Of course, if your object has no abstraction, C++ wont create a vtable for the object to obtain maximum performance.

>Is this considered bad design?

If you have to ask then the answer is always yes. Making mistakes and getting burned by them is a great way to develop an intuition for bad design though!

The correct answer is that it's bad design if you apply it in a situation where the design is not optimal.

I'm just making a roguelike, but I don't think it's too revelant, I'm just trying to make an easy to scale structure for the game states/loop, the type of game should really affect how this works should it?

I want to try and avoid having a big switch statement if at all possible, I'm gonna keep experimenting, thanks

>>15246359

Your good at getting a season 2.

>>15246421

>I want to try and avoid having a big switch statement if at all possible

For what reason?

On a marginally related topic, for C programming I recommend learning a function naming convention that makes it easier to find/remember things. I prefix the names with the subject, and add the target after it, for example "render_someObject" and "render_anotherObject". Then that switch statement would look something like this;

switch(e->type) {
	case ENTITY_SOMEOBJECT: render_someObject(e); break;
	case ENTITY_ANOTHEROBJECT: render_anotherObject(e); break;
	default: render_genericObject(e); break;
}

>>15246421

>I'm just making a roguelike, but I don't think it's too revelant, I'm just trying to make an easy to scale structure for the game states/loop, the type of game should really affect how this works should it?

Of course. If a game doesn't need abstraction, then why would you introduce any in the first place?

In fact, roguelike is one of those genres that really doesn't need abstractions. It's a common staple of the series that every entity is capable of the same things. Whether it's a shopkeeper, quest-giver or the occasional neutral; every one of them has the same combat capabilities as enemies that it'll use against you if you upset it.

>I want to try and avoid having a big switch statement if at all possible, I'm gonna keep experimenting, thanks

Big switches are ugly, but using function pointers when you have only 2~3 entity types is even uglier.

>>15246359

I'm starting to think negative motivation is more powerful than positive. Look up SBN3 on YouTube, find his Rogue One video. Great twist at the end, makes ya want to be someone. Saw that a couple months back and been turning my shit around because of it.

>>15246499

I think you're misunderstanding what I'm doing, I'm not making the game yet, I'm working on the loop and game states, like menu state, loading state and then game state, I haven't even begun the actual game yet. Which is what I meant by it not really mattering. I'm not planning on abstracting everything anyway, that was just my inital idea for a base struct to hand updating and initalising things. Thanks anyway man, I'm gonna keep trying stuff

>>15246493

Because I don't like it

>>15246642

It is his "The Last Jedi" video. It really is a good video.

I think that we've immersed ourselves in negativity to the point that it no longer affects us. So when a part negative/part motivational statement is made, we only feel the motivational aspect.Or maybe it's just two talented creators with a lot of writing experience intentionally using reverse psychology.

>>15244722

Especially when you're making a porn game.

>>15246698

>Which is what I meant by it not really mattering.

Sorry. I misread your post. and you made a typo

It really does matter though. Different kinds of games require different approaches and data structures. A "one size fits all" solution doesn't exist, especially if you want to build complex features like online multiplayer.

You need both positive and negative examples to improve. Can't train a dog on just discouraging it, you have to reward it sometimes too. I spend a lot of time looking at good examples of art and analysing it, but I also spend just as much time shitposting and complaining about bad art in games.

>>15251324

i've been trying to do the same thing for days now and still can't get it to work quite right

easiest option is to only do this when your character is turning

problems occured for me when i wanted to also do it for strafing, because then the directions conflict, and having one rely on the other ends up with a lot of janky-looking rotations

this is the entire code i use for movement

}
		public Quaternion Rotate(float _yaw,float _pitch,float _roll,float step)
		{
			Quaternion _rot = Quaternion.Lerp(self.rotation,Quaternion.Euler(_yaw,_pitch,_roll),step);
			//roll has it's own timestep, if any
			self.rotation = Quaternion.Euler(_rot.eulerAngles.x,_rot.eulerAngles.y,_roll);
			return self.rotation;
		}
		float roll=0;
		[HideInInspector]
		public float yaw,pitch;
		float lastPitch;
		void HandleMovement()
		{	
			Vector3 dir = self.InverseTransformDirection(nav.velocity).normalized;
			float deltaPitch = (pitch-lastPitch)*(1-Mathf.Abs(dir.x));
			float cRoll = Mathf.Clamp(-(deltaPitch+dir.x)*Mathf.Abs(dir.z)*150,-15,15);
			if(Mathf.Abs(cRoll)>0.1f&&curAnimState==AnimState.idle)
			{	
				roll = Mathf.Lerp(roll,cRoll,Time.deltaTime*4);
			}else{
				roll = Mathf.Lerp(roll,0,Time.deltaTime*4);
			}
			Rotate(yaw,pitch,roll,Time.deltaTime*8);
			Vector3 d = self.InverseTransformDirection(nav.velocity);
			anim.SetFloat("Speed", Mathf.Clamp(d.z, Walking ? -0.5f : -1, Walking ? 0.5f : 1), 0.1f, Time.deltaTime);
			anim.SetFloat("Direction", Mathf.Clamp(d.x, Walking ? -0.5f : -1, Walking ? 0.5f : 1), 0.1f, Time.deltaTime);
			lastPitch = pitch;
		}

but if you only want it for when your dude is turning, ignore the delta pitch

>>15251352

actually ignore that, it's absolute spaghetti

pseudocode would work better

float roll = 0;
void HandleRollRotation()
{
	Vector3 dir = self.InverseTransformDirection(velocity).normalized;
	float cRoll = Mathf.Clamp(-dir.x*Mathf.Abs(dir.z)*150,-15,15);
	if(Mathf.Abs(cRoll)>0.1f)
	{
		roll = Mathf.Lerp(roll,cRoll,Time.deltaTime*4);
	}
	else
	{
		roll = Mathf.Lerp(roll,0,Time.deltaTime*4);
	}
	Rotate(yaw,pitch,roll,Time.deltaTime*8);
}

>>15251364

I'll give this a shot, thanks anon

>>15251352

>>15251364

I think I might've explained myself wrong.

I'm not looking to change the roll of my character, my question was more about how to widen the rotation when spinning the analog stick and on how to not interrupt the spinning before its done

>>15251443

oh no idea

doesn't that happen naturally when you're not with a mouse?

the radius of the spin depends on how much your rotation is limited

>>15251461

Well it does if the rotation is happening slowly, but if the direction vector goes faster than the rotation can complete then another rotation will start

>>15251461

Good roll script though

>>15251468

>but if the direction vector goes faster

so limit the speed while turning

>>15251475

oh fuck that might work

>>15251564

Volumetric meshes might be up your alley.

>>15252002

you do the rotation yourself

Vector3 currentRot = Quaternion.LookRotation(vector).eulerAngles;
Vector3 desiredRot = Quaternion.LookRotation(target).eulerAngles;
if(desiredRot.y<0)
{
	desiredRot.y+=360;
}
currentRot.y = Mathf.Clamp(currentRot.y+Time.deltaTime,currentRot.y,desiredRot.y);
transform.rotation = Quaternion.Euler(currentRot);

haven't tested but i think it makes sense

if the desired rotation is to your right, give it 360 degrees so it's actually a whole rotation to your left

then just rotate until you reach it

i could be wrong though, i've failed geometry 4 times

really wish we had a way to edit posts

That's the easiest part faggot, if I rename the files through a script I have to go through the Godot editor again and update all the project's case-sensitive references to these files. I could also make a script which combs through the scene files (pretty sure they're all plaintext) and replaces all references to these files, but all this is unnecessary for something which needs a complete rebuilding anyways.

Alright. It's nice to see you're still around Anon.

>>15252515

thanks. Since I'm here I can say something about it.

It's written in c++98 and its only dependency is sdl (although recently I managed to get the game working without it directly on /dev/fb). It should be possible to run it on any device and so far I tested windows (from 98 to 10) linux and adroid. It's lightweight. My inspiration for making this was Hotline Miami. At one point I was stuck with an old I3 processor. I thought it's good enough to play 8 bit looking game, but it was lagging quite a bit. Decided to make a good engine for low rez low color games… I think it's pretty fast so far, although I didn't try very hard to optimize it, I'm jist not being retarded and know what is expensive and how to do it better… on my 166mhz Pentium 1 laptop I get 40 fps (640x480@256 colors).

How do you handle "interactions" in a puzzle game? For example if a player object is beside a monster object, you should die. Or if a rock is inside a water tile, it is removed.

I know how to handle general behavior via events (eg OnMove, OnIdle, etc), but not sure of a good pattern to use that's flexible and lets it check for a variety of arbitrary conditions

>>15251324

>>15251443

Seems my current controller is replicating exactly as they're doing there with link.

For rotation, I use a basic rotation towards the velocity of my controller per tick by a delta, but as you figured it's highly dependent on your movement controller (how wide it turns); to actually have a proper circular path of motion (of velocity dir that forms a circular arc) to rotate towards.

Rotate towards velocity script:

//do rotation (towards velocity as forward):
Transform t;
Vector3 velocityForward;
float rotationSmoothDelta;

//spherically interpolate towards targetRot by delta per tick
//lookRot is the target rotation (towards forward velocity)
//	//in accordance w/passed delta per tick
t.rotation =
	Quaternion.Slerp (t.rotation,
		Quaternion.LookRotation (velocityForward, Vector3.up), 
		rotationSmoothDelta * Time.deltaTime);

Character controller is a bunch of layered systems so can't really post here, nor is it meshable with usual unity EC+OOP design pattern.

For main meat of my approach that results in this effect, I use the unity provided CC as a base, with a drag system (approx. of real drag), and a normal interpolated cc.ApplyMovement (dirSticks * moveSpeed) for directional movement.

It results in a nice circular movement pattern if I do a pull 360 around the extremities of my controller's directional movement analog stick.

From testing it seems the drag system is really what creates the effect.

Drag code/formula I'm using:

Vector3 controllerVelocity;
float dragFactor;	//strength of drag relative to velocity vector length
CharacterController cc;

//get drag approximation:
float dragForce = 
	controllerVelocity.magnitude * controllerVelocity.magnitude * dragFactor;
	
//scale opposite dir of velocity by drag force (or passed in "drag direction")
//	//resulting in force opposite of traveling dir (a drag approximation)
Vector3 dragVector = dragForce * -controllerVelocity.normalized;

//final steps (IFF using character controller):
//	//get step offset as to keep CC grounded (for isGrounded detection/grounded flags)
dragVector.y = -cc.stepOffset * Time.deltaTime;
//apply & get grounded flags;
cc.collisionFlags = cc.Move(dragVector);

Video games aren't all that fun honestly. I'd rather study graphics and rendering rather than develop a game.

>>15258208

Ditto. The science behind it all is much more interesting than the game design side THOUGH I would like to produce a finished product. I have a couple ideal games in my head and nobody else will make them because the games industry is trash… So I'll do it myself.

>>15258003

Code::blocks on windows. It handles projects fine, I wanted to use GCC on windows (instead of visual studio's compiler) and the visual debugger is nice.

>>15258195

Let's say my object is the player. If it's adjacent to a monster, it should be destroyed and you'll have to start the level over. So how would that look in a flat text file? You can't necessarily pass arguments like CheckAdjacent(left) since "left" is just raw text, so you'd have to interpret it, and then that might fail etc etc. I can't have this shit happening every frame

Like

>>15258746

You're trying to move the actual game logic out into text? Why would you parse every frame? Either way you need to create a strict standard that limits and defines what can be in the text files

>>15258401

>And you can use expressions in numeric fields

That's real fuckin' neato.

>>15258746

If you are having trouble imagining how to define interactions between objects, consider letting the script mark an object as a certain arbitrary type ("monster", "obstacle", etc) and letting it define some simple interactions based on distance with other types. Unless you're making an engine I don't think the actual proximity checks need to be scriptable, i.e. CheckAdjacent should probably be internal logic

>>15258764

No what I want to do is have game objects be defined in text so you can change things around without having to recompile the game. I just don't know how to tie the text data into game logic, as far as comparisons, behaviors, etc

>Unity's capsule casting returns a normal perpendicular to the surface of the capsule rather than the actual normal of the surface that was hit.

How do I go about fixing this without creating an abomination? In most cases the above is fine, but I specifically need a capsule to be able to sweep downwards and return the normal of the closest surface without being skewed by edges and corners. It would work find with a box cast since it's bottom would be flat, but I also need it to work with capsules.

>>15258832

Take the collision point, raycast downward from right above that point, use the normal from the raycast.

>>15258790

Some objects need to check adjacent tiles to see what are beside them, though. I like it'd have to be a specific object or type of object and then it does something. Alternatively, I could have it check top, then bottom, then left, then right, etc, but I don't know again how I'd have it combine checks in text

>>15258917

But that check logic should be self contained and internal, and the objects constructed from the parsed script should know what to do given whether an object of a specific type is nearby.

e.g. in the script:

[adjacent] "monster" hurt

[adjacent] "obstacle" stop

[near] "terrible" fear

[far] "friend" lonely

[adjacent-left] "spring" jump-right

With the last word being baked-in interactions and the first word being baked-in proximity checks. Obviously formatted in a nicer way, that's just an example. Then the objects just compare the type of the objects found in their proximity tests to know how to react. I'm not sure if this helps at all, it's just my naive stab at it.

>>15259040

And some sort of inheritance or prototyping would make this cleaner

>>15259051

Right but how do you do inheritance with text? Sorry, I'm feeling really stupid and tired tonight. I feel really discouraged about my game in general

>>15258878

Tried something similar to this which works most of the time, but it sometimes hits the wrong plane when on corners. Will continue trying more with this.

>>15259458

You could try a narrow box cast instead of a ray cast and see if that works any better.

I really like this video

I added a page for C in the wiki

http://8agdg.wikidot.com/c

Fix it if I wrote something retarded t. not a C pro

>>15261896

Honestly, it looks like trash but I don't know what to expect from the wiki.

>Pros: easy to learn

What does this mean?

>Encourages data-orienter thinking

Not necessarily. Should replace this with a pro being memory management compared to other languages

>Cons: Lacks of slot of modern functionality

Completely ambiguous. Mention specific things like the fact C is missing complex data structures

>game engines that support C are rare

This means what? A game engine SUPPORTS scripting languages. You probably mean it's rare to find modern game engines written in C then make a note of old id tech engines

>Sample code

It would be nice if there was a sample hello world for each language then a demonstration of a something like fizz buzz to be considtent

>>15261917

>What does this mean?

It's "small" and very straightforward. There aren't too many features to learn and there isn't a lot of things to learn about the things there are to learn.

>pro being memory management compared to other languages

Now I'm going to ask what this means. How it memory management in C different from C++ or something?

>Completely ambiguous

I didn't want to autistically list every little thing.

>This means what?

You know what it means. Every engine supports every language if you want to be pedantic enough. Nobody is going to decompile Unreal Engine so they could use it with C.

>It would be nice if there was a sample hello world for each language then a demonstration of a something like fizz buzz to be considtent

I'd like that too but I don't know other languages enough. I was wondering about what kind of piece of code to write that would show a fair amount of the language, isn't completely obtuse to people who don't write it already, and isn't too long. Even better if it does something sensible, unlike the code I made.

>>15261917

You need to write the wiki from the perspective of someone reading it for information.

If I was reading an article on Haskell and it said "it's easy to learn" and "lacks a lot of modern functionality" I would learn nothing.

Also, other languages meaning languages with garbage collection.

>>15243841

Can she become even more pathetic.

>>15261896

I'll be a good goy and write up something better later.

>>15261993

>other languages meaning languages with garbage collection

Some of the language pages had "no garbage collection" in the cons. I tried to write similarly as the other pages, plus that isn't necessarily a pro or a con in my opinion.

>If I was reading an article on Haskell and it said "it's easy to learn" and "lacks a lot of modern functionality" I would learn nothing.

You need to write a lot more than a single bullet point if you want to adequately describe what makes it easy or what functionality it's missing. I think that's meant to be just a quick overwiew of what the language is like, I'd gladly add a longer paragraph along with it going into more detail, but I'm not confident enough in my C knowledge.

>>15261896

such a page already exists:

http://8agdg.wikidot.com/wiki:programming-in-c

>>15261791

the engine is already designed around netcode. I just mean that I would probably implement online multiplayer, just without implementing prediction, etc, yet.

>>15261791

Reading between the lines of what Todd said about changing the engine for fallout online, it seems like the entire engine was originally built around a single player which means they had probably had to fix all that for fallout online.

I'm trying to check when the player is making the analog stick spin around 360 degrees at a certain speed.

Quaternion.LookRotation(stickInput).eulerAngles

This gives me the angle of the stick from 0 to 360. I was thinking of something like this

>check if angle is 30

>if true check if angle is 60

>if true check if angle is 90

etc until I get to 360

If all of these checks return true then the player has made a full spin.

Anyone got better solutions?

>>15262152

>Reading between the lines of what Todd said about changing the engine for fallout online, it seems like the entire engine was originally built around a single player which means they had probably had to fix all that for fallout online.

All for that massively* multiplayer online experience.

Am I a brainlet or can pretty much all overflow problems be easily solved by clamping values?

I accidentally hit reply instead of writing more shit & proofreading my post but I think it's better if I leave it at that

>>15262185

I'm not sure where you are ast, but this would be my complete solution

1. Store your inputs somewhere

2. Grab inputs within a certain timeframe in the past

3. Calculate the stick angles, your way is fine

4. Calculate angle deltas between each input

5. True if >= 360 or <= -360

Forgot to mention to sum the deltas

New to gamedev. Say I wanted to remake Etrian Odyssey for the PC, complete with map-drawing (would be nice if dual monitor people could have the option to display the map interface on their second monitor). I have development documents and can probably do all the art myself. Two questions:

1. What should I learn in terms of game engines and programming? Unity? Assume I'm starting from scratch even though I know some java.

2. Does anyone here commission composers for decent game music? How much does this cost?

>>15263064

>1. What should I learn in terms of game engines and programming? Unity? Assume I'm starting from scratch even though I know some java.

Using an engine like Unity or Unreal means you get to skip all the shit that comes into engine dev (rendering, audio, setting up a game loop, loading assets, etc.), letting you get results much quicker. I dev my own engines and despise other engines so don't ask me for advice.

I can't say dual monitor support is possible or not with these engines, so you'll have to do your own research for each. Note that barely any games have dual monitor support, so nobody really expect support for this. From a business perspective its safe to disregard it entirely.

>2. Does anyone here commission composers for decent game music? How much does this cost?

I don't, but there's fucking piles of free to use music. (Though it often requires attribution.) Incompetech is a very commonly used source for placeholder music in games. Free to use with attribution, cheap license if you can't even be arsed to do that.

The actual price of commissioning composers will vary wildly. You can expect to pay out of the ass for anyone well established, but new people will often make music completely for free if your game is interesting enough. That is no joke; if you lurk r/gamedev & both 4&8/agdg you'll come across people regularly offering to do so.

>>15263064

>1. What should I learn in terms of game engines and programming? Unity? Assume I'm starting from scratch even though I know some java.

Java will probably help a lot. If you're familiar with OOP all you have to learn are Unity's docs and build in functions and you're pretty much set.

Just set out to make something and search the docs for what you need and you'll end up learning pretty fast.

>2. Does anyone here commission composers for decent game music? How much does this cost?

Honestly, get a project started so that you have something to show and then go to soundcloud and find someone to collaborate with. If they like the project they might not even ask you for money.

Hiring people in this cases I think is absolutely awful because you never know how much you're going to need or if the work you get from them is going to be good enough. You might as well try to make a friend and have someone to collaborate with.

Now that I'm in a clear state of mind, I think what I want to do is load the files and while parsing them, use a stack to build a set of expression trees for behavior, then store that behavior on the object types' metadata.

Gamedevving or fusion 2?

>>15266460

Fusion 2. Are you dense?

>>15266516

I learned vector math a while ago but only felt it was useful when I started having to use it for godot. I would recommend reading up on it (the godot .pdf/wiki has plenty of info on this and other things relevant to your devving). Really, what's more important than straight math is an understanding of logic.

>>15266516

CompSci is not mathematics, mostly. You might need some calculus, trigonometry, and linear algebra for understanding CS topics like algorithms, automata, data strucutes, etc., but you shouldn't need to use these for making a pong or mario clone.

Obviously, it depends on the type of game you're making. Oftentimes, physics is a more important topic in designing games than CS. Even then, you won't need to know the math, just which math is necessary. Think about Asteroids for example. Pressing forward makes you move in the direction you're pointing. The computer has to calculate how much to add to the x and y positions of the player's ship, which is done by calculating the angle. Most programming languages have their own functions that'll calculate that angle for you, so you won't have to implement that in the code. Hence, you don't technically need to know the math, just that you'll need to use that function.

And of course the tutorials can only help you so much. They're teaching you how to get around in the engine, and how to think while using it to design your game.

Start simple: make pong, then asteroids, then pac-man, then donkey kong. None of these should require more than high-school level math.

>>15266513

Well fusion is simple enough for even a child to handle and I don't know shit about coding.

>>15266591

>Really, what's more important than straight math is an understanding of logic.

So I just need to read a few more stuff about logics and doing general programming practice to understand logic "better"?

>>15266618

> Think about Asteroids for example. Pressing forward makes you move in the direction you're pointing. The computer has to calculate how much to add to the x and y positions of the player's ship, which is done by calculating the angle.

Yeah in one hand it is a little bit more math but that is also exact the point were I am failing at already, since it also has to save a variable of the velocity and reduce it over the time. If I would try to program this part alone well I just wouldn't be able to figure it out how, from a pdf file (Michael Dawson Python for beginners) there is a "asteroid" game tutorial which uses a few bits of trigonometry and some sort of circle calculation.

>And of course the tutorials can only help you so much. They're teaching you how to get around in the engine, and how to think while using it to design your game.

Yes and that is my problem with those tutorials, they don't bother to give the learner more directions on were to continue so in order not to lose the motivation and especially momentum to keep working with the game engine. The "Dodge the creeps" tutorial was in my opinion the most boring tutorial out there, it is probably my own fault for trying to stick with it longer instead of looking for another one which is a "bit better".

>Start simple: make pong, then asteroids, then pac-man, then donkey kong. None of these should require more than high-school level math.

So I just also need to look up a list of very basic computer games and work up from there by recreating it at Godot and slowly figuring out on my own to see were my limits are and were I should keep continuing it? Well thanks for your comprehensive answer m8.

>>15266636

Then maybe you shouldn't be making games with your current knowledge

Anyone here need a shitty Blender artist for bad FBX models?

>>15266753

Show us your portfolio.

>>15266692

>since it also has to save a variable of the velocity and reduce it over the time

Saving a variable is easy, you should've done it in the tutorials. Each node is going to have a variable in its script, and movement can be made (aka position being altered) based off that variable. From there, you can reduce it by another variable (friction) on every frame. But Asteroids doesn't even have friction, so you wouldn't need to worry about it.

>So I just also need to look up a list of very basic computer games

It should seem natural as to what is "basic" and what is "complex". Outside of general limitations (a game from the 70s or early 80s should be simple), you can look at the game's AI (Hotline Miami has very simple enemies), progression (Mario 64 only needs to keep track of star count), or physics (VVVVVV has constant gravity and velocity).

>to see were my limits are

You don't have any limits, you only need to learn to do it. If you can figure out how it works, you can make it.

Valgrind is a commonly used tool to detect memory corruption.

Gotta tell you from experience there's nothing worse than a level that wasn't blocked out first with placeholders.

Do yourself a favor and get Polybrush and Probuilder

If you want a high degree of low level control over the engine itself then you are stuck because the engine is closed source without a very expensive source license. Unity is often overkill for 2d games.

>Feature creep is a hell of a drug and also the only reason anyone would play your game this is why publishers exist and why games are so boring.

It's not quite feature creep. I just want to have a lot of content, that's all, and I'm not particularly skilled at anything so I work hard. Sometimes it takes me a week to write a song, and I'm estimating about 50 or so for the full OST. I also won't forgive anything subpar, so that adds to it.

You're welcome.

What are the top 10 most redpilled things to do when your program will draw GL_TRIANGLES but not GL_QUADS?

(my method that generates the vertex data was intended for use with GL_QUADS, but still doesn't seem to display anything).

I recently found out about a rendering engine called Filament. Even if you aren't interested in the engine itself the documentation reads like a rendering textbook. Complete with diagrams, code, math equations, and screenshots. It's a good source if you want to learn about PBR.

The engine itself is open source under Apache 2.0 and is written in C++. It has a backend of OpenGL and Vulkan.

I'd say learn from their stuff but don't actually use it if possible

SDL is the library writen in C with does all the low level stuff with video sound and input, sfml is a c++ wrapper around that lib giving you RAII and "nicer" api. Might be easier to use if you're more used to working with modern c++

change the order of your members to avoid padding, your struct atm will take more bytes than you calculated.

I'm personally not going to use it because PBR doesn't appeal to me and it doesn't make sense for the games I'm making, but what's wrong with using FOSS from Google?

>>15268367

Thanks. I'm trying to work out what is best for getting my text adventure out of the command line and into it's own window. I'm writing it in C++ so it looks like SFML is the best option at the moment.

Not. Pretty much no one makes money from mobileshit, except a very select group of games such as Angry Turds.

You might be able to get money out of idiots who don't realize this and are willing to pay others to make games for them, though. It just won't be enough to live comfortable on in most first world countries.

GUYS ITS NOW

bread when?

>>15266753

only if you can get better over time

any recommendations on books for developing game engines?
