Pretty specific niche, but you guys are the most knowledgeable I can think of, and I really need some help. So basically, I have a fully working game engine (built with Rust and wgpu) and am currently working on building the editor. I can insert objects and stuff, but how do I go about attaching scripts? I could somehow open them in VSCode, although I'm not sure how to run the command line via a rust script, or require that rust be downloaded. And then how would I pick out functions? I want to search for a new function and an update function, and then call that function while passing in a single parameter which is my game's main state. Thanks!
