Class Collision

Contains a collision information passed to the OnCollisionEnter/OnCollisionExit events.

System.Object
Collision
System.Collections.Generic.IEnumerable<ContactPoint>
System.Collections.IEnumerable
Namespace: FlaxEngine
Assembly: FlaxEngine.CSharp.dll
Syntax
[Unmanaged]
public sealed class Collision : ValueType, IEnumerable<ContactPoint>, IEnumerable

Fields

ContactsCount

The amount of valid contact points (less or equal to COLLISION_NAX_CONTACT_POINTS).

Declaration
public int ContactsCount
Field Value
System.Int32

Impulse

The total impulse applied to this contact pair to resolve the collision.

Declaration
public Vector3 Impulse
Field Value
Vector3

Remarks

The total impulse is obtained by summing up impulses applied at all contact points in this collision pair.

OtherActor

The second collider (other instance).

Declaration
public PhysicsColliderActor OtherActor
Field Value
PhysicsColliderActor

OtherVelocity

The linear velocity of the second colliding object (other instance).

Declaration
public Vector3 OtherVelocity
Field Value
Vector3

ThisActor

The first collider (this instance).

Declaration
public PhysicsColliderActor ThisActor
Field Value
PhysicsColliderActor

ThisVelocity

The linear velocity of the first colliding object (this instance).

Declaration
public Vector3 ThisVelocity
Field Value
Vector3

Properties

Contacts

The contacts locations.

Declaration
public ContactPoint[] Contacts { get; }
Property Value
ContactPoint[]

Remarks

This property allocates an array of contact points.

OtherCollider

The second collider (other instance). It may be null if this actor is not the Collider (eg. Terrain).

Declaration
public Collider OtherCollider { get; }
Property Value
Collider

RelativeVelocity

The relative linear velocity of the two colliding objects.

Declaration
public Vector3 RelativeVelocity { get; }
Property Value
Vector3

Remarks

Can be used to detect stronger collisions.

ThisCollider

The first collider (this instance). It may be null if this actor is not the Collider (eg. Terrain).

Declaration
public Collider ThisCollider { get; }
Property Value
Collider
