Hello. I am trying to make a game like guitar hero. I am inside the Blue Button’s code and there are some errors. Here is the code:
package {
import flash.display.MovieClip;
import flash.ui.Keyboard;
import flash.events.*;
public class BlueButton extends MovieClip {
var _root:Object = MovieClip(root);
public function BlueButton() {
this.addEventListener(Event.ADDED, enteredFrame);
this.addEventListener(Event.ENTER_FRAME, enterFrameFunc);
}
public function enterFrameFunc(e:Event) {
if(this._currentframe > 50){
destroyButton();
}
}
public function enteredFrame(e:Event) {
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressCheck);
}
public function keyPressCheck(e:KeyboardEvent) {
trace("Hey");
}
public function destroyButton() {
this.removeEventListener(Event.ENTER_FRAME, enterFrameFunc);
stage.removeEventListener(KeyboardEvent.KEY_DOWN, keyPressCheck);
_root.removeChild(this);
trace("You are OUTTA HERE!");
}
}
}
Problem 1: 1119: Access of possibly undefined property _currentframe through a reference with static type BlueButton.
Problem 2: Can’t attach the Key_Down event listener to the stage…
Please help
