    The sprite that you collide with

  • collision Collision

Properties

_phys

Object private

The physics namespace that all physics properties go into. Those properties are:

  • system {PhysicsSystem} PhysicsSystem that this object is a part of.
  • active {Boolean} Whether or not this target is actively having physics simulated.

Default: {}

add

ObjectFactory

An object factory for creating game objects

alpha

Number

The opacity of the object.

bounds

Rectangle

The bounds of the world

children

Array

[read-only] The of children of this object.

game

Game

The game instance this world belongs to

hitArea

Rectangle | Polygon | Circle | Ellipse

This is the defined area that will pick up mouse / touch events. It is null by default. Setting it is a neat way of optimising the hitTest function that the interactionManager will use (as it will not need to hit test all the children)

inertia

Number

The moment of inertia of this object, only set this before enabling physics (has no effect after enabling)

Default: 0

interactive

Boolean

Wether or not the object will handle mouse events

Default: false

mass

Number

The mass of this object, please use setMass to set this value

Default: 0

parent

DisplayObject

[read-only] The display object that contains this display object.

particles

ParticleSystem

The particle system for the world

position

Point

The coordinate of the object relative to the local coordinates of the parent.

rotation

Number

The rotation of the object in radians.

scale

Point

The scale factor of the object.

stage

Stage

[read-only] The stage the display object is connected to, or undefined if it is not connected to the stage.

state

State

The game state this world belongs to

visible

Boolean

The visibility of the object.

Events

click

A callback that is used when the users clicks on the displayObject with their mouse

Event Payload:

  • interactionData InteractionData

collision

On Collision Event called when this sprite collides into another, or is being collided into by another. By default if something collides with a collectable sprite we destroy the collectable and if we collide with a solid tile we kill our velocity. This method will emit a 'collision' event that you can listen for

Event Payload:

  • obj Sprite

    Colliding sprite

  • vec Vector

    Collision vector (for sensors this is normalized)

  • colShape cp.Shape

    The colliding physics shape

  • myShape cp.Shape

    Your physics shape that caused the collision

mousedown

A callback that is used when the user clicks the mouse down over the displayObject

Event Payload:

  • interactionData InteractionData

mousemove

A callback that is used when the user moves the mouse while over the displayObject

Event Payload:

  • interactionData InteractionData

mouseout

A callback that is used when the users mouse leaves the displayObject

Event Payload:

  • interactionData InteractionData

mouseover

A callback that is used when the users mouse rolls over the displayObject

Event Payload:

  • interactionData InteractionData

mouseup

A callback that is used when the user releases the mouse that was over the displayObject for this callback to be fired the mouse must have been pressed down over the displayObject

Event Payload:

  • interactionData InteractionData

mouseupoutside

A callback that is used when the user releases the mouse that was over the displayObject but is no longer over the displayObject for this callback to be fired, The touch must have started over the displayObject

Event Payload:

separate

On Seperate Event called when this sprite collides into another, or is being collided into by another. By default if something collides with a collectable sprite we destroy the collectable and if we collide with a solid tile we kill our velocity. This method will emit a 'collision' event that you can listen for

Event Payload:

  • obj Sprite

    Colliding sprite

  • colShape cp.Shape

    The colliding physics shape

  • myShape cp.Shape

    Your physics shape that caused the collision
