Alright.. For the record, I've been searching on how to fix this for 2 hours now, so yeah.

Anyway, here's the issue, and it's probably half OpenGL being well.. OpenGL, and the other half being D-C interfacing.

Point is, I'm trying to draw a triangle with a custom Triangle class I made, and I'm having issues, relevant code is here:
https://github.com/MinekoRox/Breaker-Engine/blob/master/src/breaker/scene.d

https://github.com/MinekoRox/Breaker-Engine/blob/master/src/breaker/utility/graphics/primitives.d

https://github.com/MinekoRox/Breaker-Engine/blob/master/res/shaders/testShader.glsl

I assume this is probably me messing up with arrays and sizing, but I've done what I can as far as that goes so.. Maybe one of you know what to do.

Try breaking it down into a single module. Basically on render call your file's function that you handle drawing of said triangle. Relying on as little as possible on other code.

That way you should be able to use existing examples and tutorials straight. This is what really helped me with DOOGLE and working it out. I have an example for it if you want to check it out.

From the module you'll have than you can start abstracting out and testing your own code base.

I see what you're saying, and that's more or less what I've been doing, I'm asking what opengl function did I mess up to cause it not to render, because I've checked it over and over again.

Your init and finalize methods in primitives.d does not work. You need to send the vao, points_vbo and colors_vbo by ref.

Thank you, that was exactly the problem.
