Closing Thoughts When you press the spacebar, it will set the variable "keyread" on the main timeline to "Key is pressed." It will also tell the contoller movie clip to play. If the key is held, it will continually tell the controller movie clip to go to and play the label "play". When the key is released, it will stop being reset and play, until it hits frame 9 and runs the action. You can substitute any key for the spacebar by clicking in the key press field in the button actions window and pressing the key you wish to replace it with. You can also replace, in the button actions, the Set Variable: "/:keyread" = "Key is pressed." with whatever action you want to perform and loop on key press. Then replace the Set Variable on frame 9 of the controller movie clip with whatever action you want to perform on key release. The problem with this technique is that there is a lag in the time it takes to play to frame 10, creating a slight delay in performing the action of key release. The reason there isn't less than ten frames is because it has to be longer than the key-repeat rate set on the user's OS. If there are less frames in the controller, the key release action may be triggered the first time the key resets. Therefore this isn't suited for extremely precise uses, but will get the job done in more general applications.
