1061: Call to a possibly undefined method push through a refere
Im currently working on an incorporation of a couple of different projects adapted to this one. Pretty much what i want to happen is for my "hero" sprite to shoot an instance of sword out of his body.
unfortunatly im geting this error
| Line 153 | 1061: Call to a possibly undefined method push through a reference with static type Class. |
Ive searched the net to find something similar but in the last 40 minutes before i got to sleep i havent had success.

i know theres a couple of empty methods there, I am waiting to get the rest of my code working first before starting on them.
the Sword.as code :
package
{
import flash.display.*;
import flash.events.*;
import flash.utils.getTimer;
public class Sword extends MovieClip
{
private var dy:Number; // speed of movement
private var lastTime:int; // used in controlling animation
public function Sword(x,y,speed:Number)
{
this.x = x;
this.y = y;
dy = speed;
// set up animation event
addEventListener(Event.ENTER_FRAME, moveSword);
lastTime = getTimer();
}
public function moveSword(event:Event)
{
// work out how long since the last frame
var thisTime:int = getTimer();
var timePassed:int = thisTime - lastTime;
lastTime = thisTime;
// now move the plane
y = y + (dy * timePassed / 1000);
// delete the clip if its off the top of the screen
if (timePassed > 10)
{
deleteSword();
}
}
// called if bullet goes off screen
public function deleteSword()
{
parent.removeChild(this);
removeEventListener(Event.ENTER_FRAME, moveSword);
}
}
}
Thanks for any help.
