Maybe the game logic is done within shaders 🤔

Participating #retrogamejam
I'll try to make something for N64, though I have no experience with developing games for retro consoles 😆

Cool!
In the GLSLES version GameMaker currently uses, bit operations are not available, which I would otherwise used.
The rgba16float format has 64 bits, but 4 bits are unused to avoid dealing with infinities, which would break encoder.

Encode-six-values-to-rgba16float/shaders/shd_encoder_three10bit/shd_encoder_three10bit.fsh at main · HannulaTero/Encode-six-values-to-rgba16float For GameMaker to be used with web exports, for encoding six 7bit values in rgba16float. - HannulaTero/Encode-six-values-to-rgba16float

One curiosity I made some time back. If one is using rgba16float textures, but for some reason want to store six 10bit values instead, here are encoder functions: github.com/HannulaTero/...

Thanks 😊 I am still keeping the repo private until I'm ready to actually release it 😌

random(10) should be irandom(10), whoopsis.

Here are some more examples.

Simple coroutine example using FOREACH.

Coroutine example for drawing into surface.

Inspired from @jujuadams.com coroutine macrohacks, I have made own coroutine-system. Now why would I do one, if Juju has that covered?
Well I wanted triggers and other small stuff, so I can use them to split drawing for several frames, mostly for misusing fragment-shaders to do heavy computations.
