Making the Buttons

Now it's time to build the buttons that will control the rotation of the dot. Back to the scene, create another layer to be put on top of layer1. Once more, duplicate RK in the Library. In the dialog box, give the new symbol the name of 'rotation button' (RB) and will change its behavior to button. Drag an instance of RB in layer2, then align its center with the group that makes the dial and the dot.

Double-click the instance of RB to edit it in place. In the timeline, insert a keyframe in the Hit frame. Now select the Up frame, and clear the keyframe. Back on the Hit frame, use the arrow tool, draw a marquee over the right half of the circle shape, and delete it. You should have only the half of a circle.

Back on the scene, with the button selected, go to the Action panel and write down this code:

on (press) {
    tellTarget ("/ctrl") {
        gotoAndPlay ("CW");
    }
}
on (release, releaseOutside) {
    tellTarget ("/ctrl") {
        gotoAndPlay ("stop");
    }
}

Now copy the button and paste it in place. Flip the new button horizontally and move it in order to cover the other half of the group that makes the dial and the dot. (Using the Info panel, add the Width value of the button to its X value.) In the Action panel, change the line

 gotoAndPlay ("CW");

for

 gotoAndPlay ("CCW");

So far, the dial should work.
