can you give a load_asset example?

Can you give me an example of loading a third-party model to generate collisions? I loaded a third-party model myself to generate collisions, which became very slow

[Jondolf]

What method are you currently using for generating the collider? Are you using Collider::trimesh_from_bevy_mesh or Collider::convex_decomposition_from_bevy_mesh? If the model is an asset like a gltf file, you'll need "async scene colliders" which aren't built-in yet, but you can implement them in your own app pretty easily, see #104 and #135.

Also, do you mean that generating the collider at the start of the app takes time, or that the performance is bad when objects are interacting with the collider? If you're using convex decomposition, it's expected that the initial load is very slow because of the underlying algorithm, but we might be able to fix this in the future using Bevy's asset rework.

Thank you very much for your reply! This is an. rs file. I put it in main, but I'm not very good at it. The rendering is fine, but the imported mesh did not collide, Gltf loads quickly, but runs slowly, almost stuck， Can you help me take a look? Thank you again!

i use Collider::trimesh_from_bevy_mesh

Yesterday I saw you have an example of a third-party gltf import that you are about to upload. Let me take a look at that first?

Another small issue is, if multiple third-party models need to be loaded during startup, their previous order cannot be guaranteed. Do I need to merge them into one load
