And this is my code (including the first popup code):

 removeChild(popup);
 isPopup = false;
}

 removePopup();
}

rumahBtn.addEventListener(MouseEvent.CLICK,popuprumah)
function popuprumah(e:MouseEvent){
addPopup(); 
}

//popup 2//

var popup_2 = new popupBajuMC;
var isPopup_2 = false;

function addPopup_2(str=""):void{
 popup_2 = new popupBajuMC;
 popup_2.copycloseBtn.addEventListener(MouseEvent.CLICK, closePopup_2);
 popup_2.x = 643;
 popup_2.y = 360;
 addChild(popup_2);
 isPopup_2 = true;
}

function removePopup_2():void{
 popup_2.copycloseBtn.removeEventListener(MouseEvent.CLICK, closePopup_2);
 removeChild(popup_2);
 isPopup_2 = false;
}

function closePopup_2(e:MouseEvent):void{
 removePopup_2();
}

bajuBtn.addEventListener(MouseEvent.CLICK,popupBaju)
function popupBaju(e:MouseEvent){
addPopup_2();   
}

I'm trying to fix that error, and unfortunately, it fails. I have double-checked it. What do you think is the problem with this code?

Answer 1

I am new to Adobe Animate, but please allow me to share my experience.

I found nothing wrong in your code, the first popup and the second popup code are similar. I suggest that you re-checking the instance name and object/symbol properties. But if you already did that then I think it's not the code error, but more like the same problem I got recently.

My Solution

Try put your button (insert keyframe) from the first frame. You can hide it (alpha 0% or 0% width/height) or put it outside the frame if you didn't use it.
Before: Timeline Before Fix
After: Timeline After Fix
Button Code: Button Code (I didn't change this)
This do the trick for me.

Update

Finally, find a simple solution for me:
> Fixed by Disabling the "Use Advanced Layer" at Document Setting. See this picture
Note: By disabling it you can't use some features (see the popup message).

Hope this helps.
