Coroutines VS Pixel-Art-Upscaling

Anyways you might also be interested in this library: https://github.com/JujuAdams/Coroutines

You could look into using Coroutines by JuJu.

I have no experience with async/coroutines, but maybe something like this would work? https://github.com/JujuAdams/Coroutines

Getting coroutines to work in GameMaker is one thing, but making them fun to write required a creative solution. Instead of implementing a slow custom scripting language or editor-side extension to generate coroutine-esque code, this library uses native GML macros to extend GML syntax to accommodate coroutine definitions. You can read all about the new syntax here or understand how and why it works here.

I have a slight update for the last post I did for Steam Deck Scaling. PowerPlaidPlays so graciously provided me this link https://github.com/JujuAdams/Pixel-Art-Upscaling to a shader that fixes the issue I was having with the Steam Deck not scaling my pixel art correctly (My game: 480x270, Steam Deck: 1280x800). When using this shader, and setting the obj as Persistent, it scales perfectly. But, my GUI layer is being affected by it when in fullscreen. Any thoughts on how to fix this? Thanks for all the help!

Instead, use this: https://github.com/JujuAdams/Pixel-Art-Upscaling

Pixel art upscaling has multiple solutions with varying degrees of complexity, but here's one that I found to be relatively pleasing: https://github.com/JujuAdams/Pixel-Art-Upscaling
