This plugin makes it simple to create ray casting sources, such as a transform (first person, third person shooter), or screenspace coordinates (mouse picking).
- Only meshes that you mark with a component will be checked for intersections.
- You can define which ray casting source(s) should interact with which mesh(es) by marking grouped sources and targets with the same type.
- This plugin also provides some functionality to compute the intersection of rays with primitive shapes.
- Acceleration is provided using Bevy's AABBs and visibility culling.
- An immediate mode API is provided to allow raycasts on demand, as well as raycasting using components updated once per frame.
For a more full featured and performant option, consider using
bevy_rapier. Note that rapier is a full physics engine that can also do raycasting; by contrast, this crate prioritizes simplicity and ergonomics.
I intend to track the
main branch of Bevy. PRs supporting this are welcome!
