Custom mouse cursor and draggable objects - Page 4

Step 3 - Frame Actions (functions)

We will use a functions for cursor updating, because function can be called independently on framerate. I always define the global functions in the 1st frame of action layer. The calling of such functions is easy and the coding is clear and well sctructured.
Bring-up the frame actions editor by double-cliking on 1st frame in actions layer and enter this code:

stop();
/* update the cursor coords */
function updateCursor() {
	_root.cursor._x = _xmouse;
	_root.cursor._y = _ymouse;
	updateAfterEvent();
}

The _root.cursor._x = _xmouse; and _root.cursor._y = _ymouse; just updates the cursor's X and Y coordinates according to mouse position. But the main trick is in the updateAfterEvent(); function. This one is neccessary for smooth cursor movement. With this function the cursor movement will be smooth and independent on the swf's framerate ! :)
