Classpublic class ContactEvent
InheritanceContactEvent Inheritance flash.events.Event

A native flash event class for handling Box2d contact events. If a fixture's user data implements IEventDispatcher (for example, if m_userData is a MovieClip), that event dispatcher will be used to broadcast contact events involving the fixture. GOTCHA: A fixture will only dispatch contact events if reportBeginContact, reportEndContact, etc. are set to true.

Constructor Detail
ContactEvent()Constructor
public function ContactEvent(t:String, c:b2Contact, bi:int, o:b2Manifold = null, i:b2ContactImpulse = null)



Parameters
t:String
 
c:b2Contact
 
bi:int
 
o:b2Manifold (default = null)
 
i:b2ContactImpulse (default = null)
Method Detail
applyForce()method
public function applyForce(base:Number, massFactor:Number = 0, self:Boolean = false):void

Applies a force to the other body in the direction of the normal.

Parameters

base:Number
 
massFactor:Number (default = 0)
 
self:Boolean (default = false)

applyImpulse()method 
public function applyImpulse(base:Number, massFactor:Number = 0):void

Applies an impulse to the other body in the direction of the normal.

Parameters

base:Number
 
massFactor:Number (default = 0)

clone()method 
override public function clone():Event

Clone the event for re-dispatching.

Returns
Event
getWorldManifold()method 
public function getWorldManifold():b2WorldManifold

Returns the world manifold. Very important if you plan on actually doing anything significant with contacts. The normal will be oriented based on "bias" so that it is always pointing from the target fixture to the other fixture. This way you don't have to worry about the direction of the normal.

Returns
b2WorldManifold
isSolid()method 
public function isSolid():Boolean

Returns true if the contacts is touching, is not a sensor, and has not been disabled.

Returns
Boolean
preventDefault()method 
override public function preventDefault():void

Disables a contact by setting it as a sensor for the life of the contact.

update()method 
public function update():void

Update the contact. This ensures the contact has the right, current information.
