of the caller up vote 0 down vote favorite 1 After 2 days of trying and searching for an answer I still didn't found it. I keep getting Error #2025: The supplied DisplayObject must be a child of the caller. I'm making a game where if the user hits an enemy, the enemy get destroyed. The code: My main class package classes { import flash.display.MovieClip; import flash.events.Event; import flash.utils.Timer; removechild as3 public class Main extends MovieClip { var enemyTimer:Timer; public function Main() { var user:ship = new ship(); addChild(user); user.name = "user"; user.initialize(); enemyTimer = new Timer(2000); enemyTimer.addEventListener("timer", sendEnemy); enemyTimer.start(); function sendEnemy(e:Event) { var badboy:enemy = new enemy(); addChild(badboy); badboy.initialize(); } } } } the enemy class package classes.enemy { import flash.display.MovieClip; import flash.events.Event; public class Enemy extends MovieClip { var speed:Number; public function initialize() { addEventListener("enterFrame", enterFrame); } public function Enemy() { this.x = 700; this.y = Math.random()*200 + 50; speed = Math.random()*5 + 5; } function enterFrame(e:Event) { this.x -= speed; if(this.hitTestObject(parent.getChildByName("user"))) { kill(); } } function kill() { removeEventListener("enterFrame", enterFrame); stage.removeChild(this); } } } The files are in different folders (classes > Main.as & classes.enemy.Enemy.as), don't know if that has anything to do with it. Any help would be appreciated. actionscript-3 share|improve this question asked Jan 1 '12 at 20:27 Robbe Van Winckel 1602514 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted That's probably because you try to remove the Enemy MovieClip from stage, that it is not a (direct) child of. I suggest you change this: stage.removeChild(this); to this: this.parent.removeChild(this); When you have a reference to a DisplayObject, like this in this case, you c

When trying to remove a child up vote 0 down vote favorite This has been bothering me for a while now, my goal is to be able to write text via textfield onto the stage (there will be multiple textfields at once). However I want http://stackoverflow.com/questions/36669234/as3-error-2025-the-supplied-displayobject-must-be-a-child-of-the-caller-when a button to be able to remove all the text at once. I have the text working as I wanted. So basically I want the button to remove the textfield child so they're not seen anymore, but I keep getting this error, here's my code: stage.addEventListener(MouseEvent.MOUSE_UP, mUp); function mUp(MouseEvent): void { var textfield = new TextField(); textfield.type = TextFieldType.INPUT textfield.x = mouseX; textfield.y = mouseY; stage.focus = textfield; textfield.selectable = false; stage.addChild(textfield); // adding the child here } function erase(evt: MouseEvent): void { //triggers when button is clicked stage.removeChild(textfield) //trying to remove the child, but throws the error } Is the stage not a parent of the textfield? I added the texfield as a child to it so I don't see why not. This looks very straightfoward and I'm not seeing the problem, any help would be nice var board: Sprite = new Sprite(); // displayobjectcontainer to hold the textfields addChild(board); var textfield:TextField; // Declared outside the functions listener.addEventListener(MouseEvent.MOUSE_UP, mUp); // I added an object on the stage to catch my mouse input instead of the stage, so that it doesn't tri

This function works fine, nothing goes wrong, but when I publish the game and play the supplied displayobject it with Flashy Player, it shows up with the error message "Error #2025: The supplied DisplayObject must be a child of the caller." I've just been dismissing it since the program works other than the alert prompt, but I need to remove that. function spawnscore() { i = 0 while (i == 0) { var pointy = Math.random()*640 var pointx = Math.random()*747 var pointcirc:warning = new warning(); addChild(pointcirc); pointappearmusic.play(); setTimeout(removepoint, 1500); pointcirc.addEventListener(MouseEvent.MOUSE_OVER, scoreclicked); function scoreclicked() { pointsound10.play(); removeChild(pointcirc); score += 10; removeEventListener(MouseEvent.MOUSE_OVER, scoreclicked); } function removepoint() { // I'm pretty sure this is the problem removeChild(pointcirc); } pointcirc.x = pointx; pointcirc.y = pointy; break; } return; } I'm pretty sure my problem is in the removepoint function, but I can't figure out what to do. flash runtime-error removechild share|improve this question edited Mar 5 '13 at 0:17 Lee Taylor 4,56572138 asked Mar 4 '13 at 23:54 timo352 1314 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted That error means you're trying to remove a DisplayObject from a container when it
