Struct avian3d::collision::collider::CollisionMargin
source · pub struct CollisionMargin(pub Scalar);
Expand description
A component that adds an extra margin or “skin” around Collider
shapes to help maintain
additional separation to other objects. This added thickness can help improve
stability and performance in some cases, especially for thin shapes such as trimeshes.
There are three primary reasons for collision margins:
-
Collision detection is often more efficient when shapes are not overlapping further than their collision margins. Deeply overlapping shapes require more expensive collision algorithms.
-
Some shapes such as triangles and planes are infinitely thin, which can cause precision errors. A collision margin adds artificial thickness to shapes, improving stability.
-
Overall, collision margins give the physics engine more room for error when resolving contacts. This can also help prevent visible artifacts such as objects poking through the ground.
If a rigid body with a CollisionMargin
has colliders as child entities,
and those colliders don’t have their own CollisionMargin
components,
the colliders will use the rigid body’s CollisionMargin
.
§Example
use avian3d::prelude::*;
use bevy::prelude::*;
fn setup(mut commands: Commands) {
let mesh = Mesh::from(Torus::default());
// Spawn a rigid body with a triangle mesh collider.
// A margin of `0.1` is added around the shape.
commands.spawn((
RigidBody::Dynamic,
Collider::trimesh_from_mesh(&mesh).unwrap(),
CollisionMargin(0.1),
));
}
