Ich bin ein Tutorial zum Aufbau eines Rhythmus-Spiels in as3 here folgen, und ich bin sehr neu in der Sprache . Auf die swf läuft, ich folgende Fehlermeldung in der Ausgabe erhalten:as3 Fehler: ReferenceError: Fehler # 1069: Property keyCode nicht in flash.display.Shape gefunden und es gibt keinen Standardwert
ReferenceError: Error #1069: Property keyCode not found on flash.display.Shape and there is no default value.

ich einige bisherigen Lösungen auf den gleichen Fehler geschrieben habe versucht, aber ich habe es nicht gelungen, das Problem zu beheben. Hier
ist der Quellcode:

//VARIABLES
//sTime is the current frame that is being played

//and a note will be created

//the frame rate is 24, it will take a half of a second
//for a note to be made

Kann mir jemand sagen, warum dieser Fehler auftritt? Vielen Dank.
