Optionalbounds: BoundingVolumeThe physical bounding volume of the object.
32-bit collision layer bitmask this collider belongs to (default: 1).
32-bit collision mask specifying which layers this collider interacts with (default: 0xFFFFFFFF).
Coulomb contact friction coefficient (0.0 = ice, 1.0 = high grip).
Optional integer identifier for deterministic physics solver sorting and netcode lockstep.
If true, this collider acts as a trigger/sensor (fires trigger events without physical force).
Restitution / bounciness (0.0 = clay, 1.0 = superball).
A lightweight collision object that avoids the overhead of a full Object3D. Used for inserting static obstacles (like grid walls) into a SpatialHash.
