SLoC
A raycasting backend for bevy_mod_picking
that uses Avian
for raycasting.
Usage
Pointers will automatically shoot rays into the Avian scene and pick entities.
To ignore an entity, you can add Pickable::IGNORE
to it, and it will be ignored during
raycasting.
For fine-grained control, see the AvianBackendSettings::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 Avian 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 Avian entities, beware, I suppose.
