Okay, I’m searching the web and I can’t find an answer I can understand so here goes.

I have to arrays, they both hit detect against each other. When they detect a hit they each launch a method in the custom class as well as splice the entries out of the arrays. Now, I CAN NOT remove the child right their cause that causes them to immediately delete themselves from the stage, I need the death animation to play. I can’t remove them in the class cause it says it can only be removed from the caller.

So, WHAT is a caller, and how do I uh, find it and uh, call it. Example code.

```auto

for(var b=0; b<blastArray.length;b++){
                for(var s=0; s<boxArray.length;s++){
                    if(blastArray**.hitTestObject(boxArray[s])){ //test if they hit each other

                        score += 5; //scoring and level completion
                        value1 += 1;
                        
                        boxArray[s].die(); //death animations for both objects
                        blastArray**.hit();
                        boxArray.splice(s,1); //remove objects from arrays
                        blastArray.splice(b,1);
                        
                    }
                }
            }

```

If I put removeChild(this) in the boxArray method .die, I get a 2025 error.

If I try parent.removeChild(this), I get, cannot access property of a null object. 1009 error.
