Let's add the scripts.1. Create a layer on top of the motion guide and name it actions. 2. Put the following: _root.createEmptyMovieClip("cardioid",1); _root.cardioid.moveTo (225, 65.3); //The first line creates an empty movie clip that where we will trace our cardioid curve. //The second line initializes the starting position of our curve. 3.Right click on your moving circle and place the following script onClipEvent(enterFrame) { point = new object(); point.x = this.point_to_trace._x; point.y = this.point_to_trace._y; localToGlobal(point); _root.x=point.x _root.y=point.y //The above script changes the local coordinates of point_to_trace to the global (stage) coordinates //and stores them to the variable x and y on _root.
