Asset loader

[mgi388]

By any chance have you created an asset loader that works with this crate?

It's possible that the space is too opinionated at least for this crate to provide an asset loader, but I was curious if you've been using this crate with an asset loader?

I wonder if at the very least we need serde support so we can create clips and animations from RON files, for example? Again, I guess it's possible that is something that this crate should not support and those serialization types and the loader should all be created as 3rd party to this.

I have not used an asset loader in that context but I can see the use-case.

I'm not against providing some kind of animation loader with the crate as long as it's an opt-in feature.

bevy asset loader doesn't support your use case ? it supports defining atlas layout from ron afaik

The issue here is more about bevy_spritesheet_animation offering an asset format and structure for the animations. It's relatively easy to unmarshal some RON into a struct (using bevy_asset_loader and bevy_common_assets), but this is about how we could define assets outside of code such that they are ultimately the equivalent of this Rust code:

bevy_spritesheet_animation/examples/basic.rs

Lines 24 to 38 in 0ba52fb

	let spritesheet = Spritesheet::new(8, 8);
	let clip = Clip::from_frames(spritesheet.row(3));
	let clip_id = library.register_clip(clip);
	// Create an animation that uses the clip
	let animation = Animation::from_clip(clip_id);
	let animation_id = library.register_animation(animation);
	// Name the animation to retrieve it from other systems
	library.name_animation(animation_id, "walk").unwrap();

for now i have a system that run after my assets are loaded, and register all the animation to the library.
the clip and animation are generated from my GameAssets struct (with bevy_asset_loader's AssetCollection) with Reflect by iterating over the field of type Handle.

i dont find this nice and especially no type safety, but it work for me.
i hope it can help you on your use case
