// This object will always look at the mouse cursor
myTank.addEventListener(Event.ENTER_FRAME, tankEnterFrame);
// This function will be launched every frame (25 times by seconds);
function tankEnterFrame(pEvt) {
	// pEvt.currentTarget : myTank
	var mc = pEvt.currentTarget;
	// Get the radian angle between the tank and the cursor
	// You can also replace mouseX and mouseY by another coordinates
	var angleRadian=Math.atan2(mouseY-mc.y,mouseX-mc.x);
	// Convert the radian angle in dedree
	var angleDegree = angleRadian * 180 / Math.PI;
	// Set the orientation
	mc.rotation = angleDegree;
	// Display angle of rotation in degree
	txtAngle.text = Math.round(angleDegree) + "°";
