ive got this problem, i know how to check the angle between my object and the mouse, but i dont know how to make it rotate slowly to it…

i tried this codes:

```auto

//first method:
onClipEvent (enterFrame) {
	this._rotation = (Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x))*180/Math.PI;
}
//(this one doesnt have slow movement, it was just to know my code was working to detect the mouse angle)

```

```auto

//second method:
onClipEvent (enterFrame) {
	this.targetRotation = (Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x))*180/Math.PI;
	if (this.targetRotation-this._rotation>6) {
		this._rotation += 6;
	} else if (this.targetRotation-this._rotation<-6) {
		this._rotation -= 6;
	}
}

```

```auto

//third method:

onClipEvent (enterFrame) {
	this.targetRotation = (Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x))*180/Math.PI;
	if ((this.targetRotation<0 ? this.targetRotation+360 : this.targetRotation)-this._rotation>6) {
		this._rotation += 6;
	} else if ((this.targetRotation<0 ? this.targetRotation+360 : this.targetRotation)-this._rotation<-6) {
		this._rotation -= 6;
	}
}

```

```auto

//fourth method:
onClipEvent (load) {
	this.rot = this._rotation+360;
}
onClipEvent (enterFrame) {
	this.targetRotation = (Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x))*180/Math.PI;
	if (this.targetRotation+360-this.rot>6) {
		this.rot += 6;
	} else if (this.targetRotation+360-this.rot<-6) {
		this.rot -= 6;
	}
	this._rotation = this.rot;
}

```

none of them worked 😛  
can somebody help me??
