Classpublic class MouseCollision
InheritanceMouseCollision Inheritance Object

The MouseCollision class provides tools to detect collision of objects with the mouse or with a 2D coordinate relative to the screen.

Constructor Detail
MouseCollision()Constructor
public function MouseCollision(camera:Camera3D = null)

Creates a new MouseCollision object. Camera and canvas are both optional. If null, those used during the collision are selected.

Parameters
camera:Camera3D (default = null) — Camera3D object that will be used to check the collision.
Method Detail
addCollisionWith()method
public function addCollisionWith(pivot:Pivot3D, includeChildren:Boolean = true):void

Adds objects that will be used to check for collisions.

Parameters

pivot:Pivot3D — Pivot3D object to be checked for collisions
 
includeChildren:Boolean (default = true) — defines whether Pivot3D children are to be included.

dispose()method 
public function dispose():void

removeCollisionWith()method 
public function removeCollisionWith(pivot:Pivot3D, includeChildren:Boolean = true):void

Removes a Pivot3D in order to stop its checking process.

Parameters

pivot:Pivot3D — Pivot3D object to be removed.
 
includeChildren:Boolean (default = true) — defines whether Pivot3D children are to be removed.

test()method 
public function test(x:Number, y:Number, getAllPolysUnderPoint:Boolean = false, ignoreInvisible:Boolean = true, ignoreBackFace:Boolean = true):Boolean

Performs the collision check. "x" and "y" coordinates are relative to the canvas.

Parameters

x:Number — Canvas X coordinate.
 
y:Number — Canvas Y coordinate.
 
getAllPolysUnderPoint:Boolean (default = false) — Defines whether all the collisions or only the first collision are to be taken.
 
ignoreInvisible:Boolean (default = true) — Defines whether invisible objects are to be ignored.
 
ignoreBackFace:Boolean (default = true)

Returns
Boolean — true if collision occurred.
