SLoC
A raycasting backend for bevy_mod_picking
that uses rapier
for raycasting.
Usage
If a pointer passes through this camera's render target, it will automatically shoot rays into the rapier scene and will be able to pick things.
To ignore an entity, you can add Pickable::IGNORE
to it, and it will be ignored during
raycasting.
For fine-grained control, see the RapierBackendSettings::require_markers
setting.
Limitations
Because raycasting is expensive, only the closest intersection will be reported. This means that
unlike some UI, you cannot hover multiple rapier objects with a single pointer by configuring
the Pickable
component to not block lower elements but still emit events. As mentioned
above, all that is supported is completely ignoring an entity with Pickable::IGNORE
.
This is probably not a meaningful limitation, as the feature is usually only used in UI where you might want a pointer to be able to pick multiple elements that are on top of each other. If are trying to build a UI out of rapier entities, beware, I suppose.
