Question

I have an issue with my main game loop. When the player is destroyed, I remove the eventListener for the game loop. However, I get an error from the collisionCheck function that a term is undefined. Even if the collisionCheck is part of the gameLoop and the eventListener has been removed.

if(planeHP <= 0){
    removePlayer();
}

public function removePlayer(){
    removeEventListener(Event.ENTER_FRAME, moveGameObject);
    trace("removed");
}

public function moveGameObject(event:Event){
    collisionCheck();
}

I can see the “removed” trace before the error in the output window. The error is always from the collisionCheck function.

Thanks for the help.

Answer 1

The issue was that I have multiple loops in the collisionCheck and the loop calling the removePlayer wasn’t the last one so it would continue on even if I remove the listener. Just had to add a return after the removePlayer() and it fixed the issue.
