Method detail

move | () | method

`public static function move(target:DisplayObject, registration:Point, x:Number = 0, y:Number = 0):void`

Moves a `DisplayObject` to a new position (x,y) based on a registration point. The true position of the object will be (x - registration.x, y - registration.y).

Parameters

| `target:DisplayObject` — the DisplayObject to move
| `registration:Point` — the registration point of the DisplayObject
| `x:Number` (default = `0`)`` — the new x position, in pixels
| `y:Number` (default = `0`)`` — the new y position, in pixels

rotate | () | method |

`public static function rotate(target:DisplayObject, registration:Point, degrees:Number = 0):void`

Rotates a `DisplayObject` based on a registration point.

Parameters

| `target:DisplayObject` — the DisplayObject to move
| `registration:Point` — the registration point of the DisplayObject
| `degrees:Number` (default = `0`)`` — the new rotation angle

scale | () | method |

`public static function scale(target:DisplayObject, registration:Point, scaleX:Number = 0, scaleY:Number = 0):void`

Scales a `DisplayObject` based on a registration point.

Parameters

| `target:DisplayObject` — the DisplayObject to move
| `registration:Point` — the registration point of the DisplayObject
| `scaleX:Number` (default = `0`)`` — the new x scaling factor
| `scaleY:Number` (default = `0`)`` — the new y scaling factor
