Struct heron_core::PhysicMaterial [−][src]
Expand description
Component that defines the physics properties of the rigid body
It must be inserted on the same entity of a RigidBody
Example
fn spawn(mut commands: Commands, mut materials: ResMut<Assets<ColorMaterial>>) {
commands.spawn_bundle(todo!("Spawn your sprite/mesh, incl. at least a GlobalTransform"))
.insert(CollisionShape::Sphere { radius: 1.0 }) // Make a body (is dynamic by default)
.insert(PhysicMaterial {
restitution: 0.5, // Define the restitution. Higher value means more "bouncy"
density: 2.0, // Define the density. Higher value means heavier.
friction: 0.5, // Define the friction. Higher value means higher friction.
});
}
Fields
restitution: f32
Coefficient of restitution. Affect how much it “bounces” when colliding with other objects.
The higher the value, the more “bouncy”.
Typical values are between 0 (perfectly inelastic) and 1 (perfectly elastic)
density: f32
Density. It affects how much the body resists forces.
The higher the value, the heavier.
Value must be greater than 0. Except for sensor and static bodies, in which case the value is ignored.
friction: f32
Friction. It affects the relative motion of two bodies in contact.
The higher the value, the higher friction.
Typical values are between 0 (ideal) and 1 (max friction)
Implementations
Perfectly inelastic restitution coefficient, all kinematic energy is lost on collision. (Do not bounce at all)
Perfectly elastic restitution coefficient, all kinematic energy is restated in movement. (Very bouncy)

Returns a serializable value, if serialization is supported. Otherwise None
will be
returned. Read more
Returns a hash of the value (which includes the type) if hashing is supported. Otherwise
None
will be returned. Read more
Returns a “partial equal” comparison result if comparison is supported. Otherwise None
