| EllipsoidCollider | () | Constructor |
public function EllipsoidCollider(radiusX:Number, radiusY:Number, radiusZ:Number)Creates a EllipsoidCollider object.
ParametersradiusX:Number — Ellipsoid radius along X axis.
| |
radiusY:Number — Ellipsoid radius along Y axis.
| |
radiusZ:Number — Ellipsoid radius along Z axis.
|
| calculateDestination | () | method |
public function calculateDestination(source:Vector3D, displacement:Vector3D, object:Object3D, excludedObjects:Dictionary = null):Vector3DCalculates destination point from given start position and displacement vector.
Parameters
source:Vector3D — Starting point.
| |
displacement:Vector3D — Displacement vector.
| |
object:Object3D — An object at crossing which will be checked. If this is a container, the application will participate and its child objects
| |
excludedObjects:Dictionary (default = null)Object3D and its children.
The objects that are keys of this dictionary will be excluded from intersection test.
|
Vector3D — Destination point.
|
| getCollision | () | method |
public function getCollision(source:Vector3D, displacement:Vector3D, resCollisionPoint:Vector3D, resCollisionPlane:Vector3D, object:Object3D, excludedObjects:Dictionary = null):BooleanFinds first collision from given starting point aling displacement vector.
Parameters
source:Vector3D — Starting point.
| |
displacement:Vector3D — Displacement vector.
| |
resCollisionPoint:Vector3D — Collision point will be written into this variable.
| |
resCollisionPlane:Vector3D — Collision plane (defines by normal) parameters will be written into this variable.
| |
object:Object3D — The object to use in collision detection. If a container is specified, all its children will be tested for collison with ellipsoid.
| |
excludedObjects:Dictionary (default = null)Object3D and its children.
|
Boolean — true if collision detected and false otherwise.
