InheritanceAutoPickingCollider Inheritance Object
Implements IPickingCollider

Auto-selecting picking collider for entity objects. Used with the RaycastPicker picking object. Chooses between pure AS3 picking and PixelBender picking based on a threshold property representing the number of triangles encountered in a SubMesh object over which PixelBender is used.

Constructor Detail
AutoPickingCollider()Constructor
public function AutoPickingCollider(findClosestCollision:Boolean = false)

Creates a new AutoPickingCollider object.

Parameters
findClosestCollision:Boolean (default = false) — Determines whether the picking collider searches for the closest collision along the ray. Defaults to false.
Method Detail
setLocalRay()method
public function setLocalRay(localPosition:Vector3D, localDirection:Vector3D):void

Sets the position and direction of a picking ray in local coordinates to the entity.

Parameters

localPosition:Vector3D — The position vector in local coordinates
 
localDirection:Vector3D — The direction vector in local coordinates

testSubMeshCollision()method 
public function testSubMeshCollision(subMesh:SubMesh, pickingCollisionVO:PickingCollisionVO, shortestCollisionDistance:Number):Boolean

Tests a SubMesh object for a collision with the picking ray.

Parameters

subMesh:SubMesh — The SubMesh instance to be tested.
 
pickingCollisionVO:PickingCollisionVO — The collision object used to store the collision results
 
shortestCollisionDistance:Number — The current value of the shortest distance to a detected collision along the ray.

Returns
Boolean
