Constructors

constructor

new EdgeCollider(options: EdgeColliderOptions): EdgeCollider
Parameters
- options: EdgeColliderOptions
Returns EdgeCollider

Properties

begin

begin: Vector

end

events

events: EventEmitter<any> = ...

`Readonly` id

id: Id<"collider"> = ...

offset

offset: Vector

Pixel offset of the collision collider relative to the collider, by default (0, 0) meaning the collider is positioned on top of the collider.
