Clearing the stage (in preparation for the next level)

Hey everyone,

Me again. I got the level I was working on to work correctly, but now a new problem has risen.
I'm trying to clear the stage of all objects on there, so that I can show the next part of the game (albeit in a new frame, or by adding new MCs onto the stage).
Basically, I have a loop checking to see whether or not the player has reached the end of the current level, as well as checking if the stage has been cleared yet:

Code:

---

else if((stop_all == true)&&(empty_stage == false)){
        cleanup();
}

---

The 'else' is definitely needed. stop_all is set to true as soon as the player reaches the end of the level, empty_stage is initially set to false.

Code:

---

function cleanup():void{

for (var si=0; si<stage.numChildren; si++){
    children.push(stage.getChildAt(si));
}
for (si=0; si<children.length; si++){
    children[si].parent.removeChild(children[si]);
        }
        empty_stage = true;
        gotoAndPlay("bonusgame");
        //setEnd();
}

---

Code:

---


function setEnd():void{
        endtext.x = 500;
        endtext.y = 500;
        endtext.text = ("Gefeliciteerd!!Je hebt een topsnelheid van ");
        addChild(endtext);
        trace(endtext.text); // This one works.
}

---

All of the needed variables are declared, but the object just won't show up (other objects won't either). However, I can still trace out endtext's text, x and y, alpha and other properties.

I've also tried a gotoAndPlay("nextPartOfGame") instead of the setEnd() function, but to no avail.

Again, any help would be much appreciated.

PS: .fla and .as files can be uploaded on request.

See this thread for the answer to why it's not clearing things reliably: http://board.flashkit.com/board/show...emoveChildAt(0)

And use this to correct:

PHP Code:

---

function cleanup():void{
    while(stage.numChildren){ stage.removeChildAt(0) };
    empty_stage = true;
    gotoAndPlay('bonusgame');
}

Hi, thanks for your fast reply. It now throws me an error though:

Code:

---

TypeError: Error #1009: Cannot access a property or method of a null object reference.
        at Game_fla::MainTimeline/cleanup()
        at Game_fla::MainTimeline/loop_lv5()

---

With loop_lv5 being the loop to check when cleanup() should be executed.

I found the error: I was addressing the stage instead of the MainTimeline, like I should have. Here's the correct code:

PHP Code:

---

function cleanup():void{
    while(this.numChildren >0){
        this.removeChildAt(0);
        trace(this.numChildren);
    }
}
