delete event listeners per object?

Hi,

how do i detect if an object has an eventlistener and delete it if it does ?

Since adding eventlisteners does not return an ID, there is no way of keeping track of object event listeners. I have removed the objects, but still see some memory leaked. does removing the object also remove the eventlisteners associated? if not, how do i detect eventlisteners and remove them during the cleanup process?

First of all, no, eventlisteners are not always removed when the object is removed. The easiest way to remove them is with

object:removeEventListener

I’m not sure why you’d need to detect eventlisteners… shouldn’t you know about all of them when you added them in your code?

From my experience, using director class, I always have to manually remove “enterFrame” eventlisteners, but not “tap” or “touch”. Not sure why… [import]uid: 18951 topic_id: 12200 reply_id: 44996[/import]
