Question

I am working on a flash game and about finished with it but I’m running into an issue. When the game ends, or the user presses the “End Game” button I want to return them to the main menu. The game is set up so that the main menu is on the 3rd frame, and the game runs in the 4th frame. All of the game code is there.

A few things I have tried:
I just simply tried to return to the 3rd frame. This results in the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at Hundred_fla::MainTimeline/GotoEndGame()[Hundred_fla.MainTimeline::frame5:66]

I have tried returning all the game vars to their default values, removing all children… so on… I also get the exact same error… not sure what the problem is. I thought one solution would be to reload the movie, but this will be running on Android/IOS and I cannot refresh a webpage. … any help would be greatly appreciated. Thanks

Edit: The code on line 66 is:

while(stage.numChildren > 0){
    stage.removeChildAt(stage.numChildren-1);
}

You should lock stage link before trying to purge it of objects. You are seemingly removing the instance that runs the code, so it loses stage reference.

var theStage:Stage=stage;
while(theStage.numChildren > 0){
    theStage.removeChildAt(0); 
    //you can always be sure that element at [0] exists, rather than going for [numChildren-1]
}
