I’ve been playing with LWJGL a little, as a bit of a step up from Pygame. I’m trying to render a sprite and I was wondering if LWJGL has a function similar to Pygame’s colorkey that lets you define a color in an image that will be rendered as transparent. Do you have to use an alpha channel in OpenGL?
OpenGL doesn’t have any built in color keying support. You’ll need to either manually swap your key for alpha on the CPU, or use a custom shader that replaces it on the fly.
