How to get &mut Scene? about fyrox HOT 5 CLOSED

I'll add this information to the book.

Same question regarding renderer?

fn set_quality_settings(renderer: &mut Renderer) {
    let mut settings = QualitySettings::high();

    // Disable something.
    settings.use_ssao = false;
    settings.fxaa = false;

    // Apply.
    Log::verify(renderer.set_quality_settings(&settings))
}

I've found zero examples which use any kind of builder, but UI. Frustrating :(

Hi! You need to borrow a scene from the container: let scene = &mut context.scenes[self.scene]. It can be done in pretty much any methods of your plugin. Keep in mind, that game template uses async scene loader and self.scene will be set to a correct value on after the scene is fully loaded. So ideally, you should do a checked borrow if let Some(scene) = context.scenes.try_get_mut(self.scene) { ... }. Also, if you need to catch the moment when you scene is fully loaded, then you could place your code in the place where the scene is fetched from the async loader (here for example - https://github.com/FyroxEngine/Fyrox-demo-projects/blob/main/sound/game/src/lib.rs#L137).

About the renderer: you can access it from graphics context. For example: if let GraphicsContext::Initialized(ref mut graphics_context) = plugin.graphics_context { ... }. Notice the GraphicsContext::Initialized - since creation of the graphics context is delayed to Event::Resumed, at the start of your app, there's no GraphicsContext, it will be created shortly after. If you need to catch the moment when it is fully initialized, use Plugin::on_graphics_context_initialized method.

These quirks are here, because the engine supports WebAssembly and Android. Both of these platforms enforces their limitations and we have to live with them.
