Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. It's not the same, velocity is a vector.

You'd be better off using an ImageData, and updating an Image with its contents each frame with :replacePixels. This, and using FFI pointers and C structs, for a huge performance boost. It's fast enough for FullHD software rendering with 300+ FPS, even on my potato PC. https://i.ibb.co/mvn9PkN/love...

Runs way better. 15 FPS and massive stuttering vs fluid 60 FPS with only a few drops if I fly faster.

Yep, simple shaders like in your case are pretty easy to write, even without much knowledge. If you know what you want to achieve, it's straight forward.

You mean 2 different UV sets for multi texturing? I've never done it myself but I would search the web for GLSL shaders from others who have done multi texturing like light mapping or AO before and adapt it to Love2D. Custom vertex attributes and how to use them, is explained in the Wiki. But I thin...

Each vertex already has RGBA vertex color attributes that you can use.

Yes, there are LuaJIT decompilers

He's using the same texture, just different UV's. So it should be possible with only one mesh and a shader.

I haven't done it before, but it's possible to use 2 different UV values with custom vertex attributes that you send to a shader.

You don't need to use massive canvases. They only have to have the size of the screen. You can do the scrolling by streaming new vertex coordinates to your meshes.
