Got error #1006 removeChild is not a function. Timer Delay removeChild

Question

Hey there,

I'm trying to build a conditional statement that will addChild and removeChild at different Timer Delays. Before I go any further, I thought, I should mention that I'm usinig TweenMax to ease the alpha of ease Child from 1 to 0 and back during the process to imitate a fade-in/out.

I'm getting issue with only one line - inside a conditional statement. It's running "OK". The movie runs as I want it, but the remove/addChild transitions are not at the speed I want it at. I am getting an error message in the output, but other than that, the movie runs fine.

Please note, I'm still quite the novice in AS3. My script is repetitive and long. Sorry! I've commented where the error is located. Thank you in advanced!!

Answer 1

you're probably losing context with the way you have the function nested (the one that is having the issue). It seems to be thinking that "this" isn't either (1) the stage, or (2) a DisplayObject. What happens when you run throw a breakpoint on that line and run in debug?

Edit: You're adding the eventListener onto a Timer object -- Timer is not a DisplayObject, and therefore doesn't have removeChild as a function.
