CompositeCollider

A collision collider specifies the geometry that can detect when other collision colliders intersect for the purposes of colliding 2 objects in excalibur.

Constructors

constructor

• new CompositeCollider(colliders: Collider[]): CompositeCollider

• Overrides Collider.constructor

  Parameters

  • colliders: Collider[]

  Returns CompositeCollider

Properties

publiccomposite

composite: CompositeCollider = null

Inherited from Collider.composite

Composite collider if any this collider is attached to

WARNING do not tamper with this property

publicevents

events: EventEmitter<any> = ...

Inherited from Collider.events

publicreadonlyid

id: Id<collider> = ...

Inherited from Collider.id

offset

offset: Vector = Vector.Zero

Inherited from Collider.offset

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

publicowner

owner: Entity<any>

Inherited from Collider.owner

Accessors

axes

• get axes(): Vector[]

• Overrides Collider.axes

  Return the axes of this particular collider

  ---

  Returns Vector[]

bounds

• get bounds(): BoundingBox

• Overrides Collider.bounds

  Return the axis-aligned bounding box of the collision collider in world coordinates

  ---

  Returns BoundingBox

center

• get center(): Vector

• Overrides Collider.center

  The center point of the collision collider, for example if the collider is a circle it would be the center.

  ---

  Returns Vector

publiccompositeStrategy

• get compositeStrategy(): separate | together
• set compositeStrategy(value: separate | together): void

• Returns separate | together

• Treat composite collider's member colliders as either separate colliders for the purposes of onCollisionStart/onCollision or as a single collider together.

  This property can be overridden on individual CompositeColliders.

  For composites without gaps or small groups of colliders, you probably want 'together'

  For composites with deliberate gaps, like a platforming level layout, you probably want 'separate'

  Default is 'together' if unset

  ---

  Parameters

  • value: separate | together

  Returns void

localBounds

• get localBounds(): BoundingBox

• Overrides Collider.localBounds

  Return the axis-aligned bounding box of the collision collider in local coordinates

• Overrides Collider.worldPos

  Position of the collision collider in world coordinates

  ---

  Returns Vector

Methods

addCollider

• addCollider(collider: Collider): void
