This Key class for AS3 enables AS2-styled keyboard event behavior through a single static class. Simply call Key.init() once to initialize the class, and from there you can use Key.beginCapture() and Key.endCapture() to start and end the keyboard event listeners respectively. Also included in this class are all of the Flash key code values so you don't have to look them up.
- com.mcleodgaming.util.Key
Copy the included com folder to your project's root code directory, and add the import to the top of your classes that will be using it:
import com.mcleodgaming.util.Key;Then initiate the class in your code (only needs to be done once)
Key.init();Once initiated, you are then able to use the following functions:
Key.beginCapture(targetObject:DisplayObject):void - Begins capturing keyboard input based on the focus of the provided target DisplayObject. Supply the SWF stage object for global capture.
Key.endCapture():void - Stops keyboard input capture.
Key.isDown(keyCode:int):Boolean - Returns true if the supplied key code is pressed, or false otherwise. All of the Key codes can be accessed as static constants directly through the Key class.
Free to use in any projects without notifying me, nor is credit needed (though it'd be much appreciated!). Just do not re-distribute it under anyone else's name and be sure to retain the copyright notice in the source!
