### Start tracking another object
```javascript
obj.track(target, {
// Default options:
offsetX : 0,
offsetY : 0,
trackRotation : false,
rotateOffset : false,
disableBodyMoves : true
})
```
- `obj` is a [Sprite][1] or [Emitter][2]
- `target` is a Display Object, a [Pointer][3], or any object with `x` and `y`
- `trackRotation`: match the object’s `rotation` to the target’s `rotation`
- `rotateOffset`: rotate the offset around the target by the target’s `rotation`
- `disableBodyMoves`: suspend the object’s physics movement while tracking
An Emitter moves its launch point ([emitX][4], [emitY][5]) to follow the target. A Sprite moves its [position][6].
The object stops tracking only if
- the target is destroyed; or
- a Pointer target is deactivated; or
- you call `untrack`
It doesn't stop tracking if the target is killed.
It will not track while its own `exists` is false.
### Stop tracking
```javascript
obj.untrack()
```
