The texture_coords of a circle or rectangle or line are always vec2(0,0), because the texture is just one white pixel (or at least it behaves as if it is). I can't look into your shader in enough detail now but maybe that info helps.

There's no scene library in that list, so let me point to this one:

Unless by scenes you mean states.

Here's the PoC mentioned which handles (binary) alpha. It's almost the same program above; the only change is the addition of a pixel shader to main.lua. @zorg wouldn't that imply you have to draw everything twice? @raidho36 Nice recap. One issue I see with CPU sorting is that batches need to be reg...

I don't have time now to write a PoC (maybe later today) but for full transparency handling (edit: by "full" I meant "binary", i.e. fully opaque or fully transparent), see https://learnopengl.com/Advanced-OpenGL/Blending - the section titled "Discarding fragments". It all boils down to use a pixel s...

Hi, welcome to the forums! It defines the number of bits per sample in the depth buffer. I believe 24 is the standard. 32 does not work in my system. This is necessary if you want to use the default depth buffer for the screen. I think you can use a canvas as a depth buffer, and in that case you don...

If you're concerned about performance, you can use ReFreezed's LuaPreprocess . Personally I don't disable assertions in production code. It's important to be able to get useful bug reports when problems arise. I don't use the system's assert; instead I use a version that allows me to specify the mes...

If 'multiply' with a single colour is all you need, then yes, setColor should work (the problem is that it doesn't leave any whitish highlights like other blending modes do; such plain tinting is inadequate for some applications). LÖVE's blending modes are just a small subset of what GIMP or Photosh...

ImageData works with pixels. Right off the bat I don't remember any others.

You first need to come up with a procedure that fits your needs. Experiment with gimp until you know what process should be applied to every image. Once you have the procedure, you can mimic it with LÖVE in one of several ways. Processing ImageData with ImageData:mapPixel is one. Using canvases and ...

You don't need angles for this :) Every time you're calculating an angle just to take its sine or cosine, chances are you're wasting calculations. if distance > stepSize then -- if we're further away than stepSize, move towards the mouse's location in a straight line circle.x = circle.x + (mouse.x -...
