in pub fn setup_ui(res_font: ResMut), you can just use Res instead, as you're not mutating it.įor future reference, this reply applies for Bevy 0.5.

init_resource(ResFont), which would then call the Default implementation. insert_resource(ResFont::default()) you could just use. Storing the handle in a resource ensures it will never be unloaded. This would usually be unlikely to happen for a font used in the UI, but could be more common for other types of assets you want to stay loaded at all times. The asset server will unload an asset if no more handles to it exist. This is not Bevy-specific, but applies to game development in general. It is intended to be used for game logic.

Bevys Time gives you timing information that is consistent throughout the frame update cycle. So when is storing handles in a resource superior to asset_server.load? This will result in inconsistent / jittery timings and make your game misbehave or look stuttery.

(This can be seen in the source code of the AssetServer::load_async method, specifically l. Repeatedly calling asset_server.load works because internally, the function checks if the asset has already been loaded and reuses said asset. You could simply do that whenever you need, and not bother storing handles. If you don't have your handle stored anywhere, you can always generate one from a path by calling asset_server.load. You could store your handles somewhere that is convenient for you (such as in resources). The clone is a cheap operation, but it is explicit, to ensure that you are aware of the places in your code that create additional handles and may affect the lifetime of assets. clone() to create multiple handles to the same asset. This allows Bevy to track if an asset is still needed, and automatically unload it when it no longer is. Handles have built-in reference counting (similar to Rc/Arc in Rust). No you're not copying the Font, just the Handle.I'm going to quote the parts relevant to your questions here: Regarding your questions, I'd recommend you to give the (unofficial) bevy cheatbook's chapter on assets a read, it will answer most of your questions. Is this the 'proper' way to keep resources loaded and for use later, or is there is a better way to achieve this that I don't know of?

I am learning Rust and Bevy engine, and I want to keep certain assets (such as Fonts) loaded during the entire application life-time.
