    pub entity1: Entity,

}

All contacts between two colliders.

The contacts are stored in contact manifolds. Each manifold contains one or more contact points, and each contact in a given manifold shares the same contact normal.

Fields

entity1: Entity

First entity in the contact.

entity2: Entity

Second entity in the contact.

body_entity1: Option<Entity>

The entity of the first body involved in the contact.

body_entity2: Option<Entity>

The entity of the second body involved in the contact.

manifolds: Vec<ContactManifold>

A list of contact manifolds between two colliders. Each manifold contains one or more contact points, but each contact in a given manifold shares the same contact normal.

is_sensor: bool

True if either of the colliders involved is a sensor.

during_current_frame: bool

True if the bodies have been in contact during this frame.

during_previous_frame: bool

True if the bodies were in contact during the previous frame.

total_normal_impulse: Scalar

The total normal impulse applied to the first body in a collision.

To get the corresponding force, divide the impulse by Time<Substeps>::delta_seconds().

total_tangent_impulse: Vector2

The total tangent impulse applied to the first body in a collision.

To get the corresponding force, divide the impulse by Time<Substeps>::delta_seconds().

Implementations

impl Contacts

pub fn total_normal_force(&self, delta_time: Scalar) -> Scalar

The force corresponding to the total normal impulse applied over delta_time.

Because contacts are solved over several substeps, delta_time should typically use Time<Substeps>::delta_seconds().

pub fn total_tangent_force(&self, delta_time: Scalar) -> Vector2

The force corresponding to the total tangent impulse applied over delta_time.

Because contacts are solved over several substeps, delta_time should typically use Time<Substeps>::delta_seconds().

Trait Implementations

impl Clone for Contacts

fn clone(&self) -> Contacts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Contacts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Contacts

fn eq(&self, other: &Contacts) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
