General / Re: Update texture in Rust

This looks like a scenario where RefCell<> would come in handy. You're trying to mutate something that already has an immutable borrow out there, so maybe you could do:

Code: [Select]

let mut image = Image::from_color(WIDTH, HEIGHT, &Color::GREEN).unwrap();
let texture = RefCell<Texture>::new(Texture::from_image(&image).unwrap());
let sprite = Sprite::with_texture(texture.borrow());
texture.borrow_mut().update_from_image(&image, 0, 0);

i have NOT tested this, nor have i actually used RefCell before I just remember this from my learnings.

Edit: yeah no that didn't work at all lol it just panics, back to the drawing board
