I have an event driven flash program. I need to be able to call removeChild() if and only if an object is a child. getChildByName() and most other functions don't seem to allow for this and if you call removeChild() on an object that isn't a child it will throw an error. I suppose an option may be to catch the thrown error and just ignore it, but that seems like a bad solution.

View 3 RepliesMy page has 2 tab menus. When the page first loads, it defaults to the first tab, but when the second tab is hit, an image is loaded to the stage. I want to remove the image from the stage once the first tab is hit again.I keep getting the error "Access of undefined property Image1" but the whole point is to check if this child exists with the if statement.
//Tab 1
if (Image1 != undefined) {
stage.removeChild(Image1);

I m making a basic menu effect. Normally I would animate all this in flash on the timeline but im trying to learn as much as i can about coding. I was actually impressed that i was able to create just this simple animation, but i want to write a conditional that lets me see if a child exists on the stage, if so remove it, if not run a function. Heres where I am so far.[code]as you can see the hardware text drops down and comes in from the top but stays on screen when you mouse out.basically what i want to do in my hardwareOut function is to run a conditional to see if topText exists, if so remove it and if not then gotoAndPlay().
View 4 RepliesI have been through many threads and none have helped. I am trying to remove a child if it exists. I am clicking on the button and sometimes there is no other child loaded. I want some code that looks to see if a child is loaded and then if so unloads. There are going to be at lease 5 possible .swf files loaded. [code]

How can I determine if a child is present or not in a movieClip?
I'm trying to set up a conditional to determine whether or not a specified child object is present and if so, remove it. I'm having trouble finding relevant documentation on this.
How can I get the X, Y, and rotation values, relative to the stage of a child of unknown number of parents?What I am doing is: I have a 'stick' object, that creates a child 'stick', that creates a child 'stick', etc a random number of times.The end stick then creates a leaf. Each new stick rotates a little bit randomly.As a result when my leaf falls off the final stick it flies off in a strange direction.How can I get the leaf to fall down (eg y++ relative to stage)?Alternatively I thought I could dispatch an event that has a leaf created at the stage level but then I really need to know what the X and Y co-ordinates of my final stick is realtive to the stage.

The problem now only the " if (url == null) { " is read, thus returning those results. I believe the issue is within the definition of url " var url = txtBox_mc.getTix.url; "...
Let's say I have a canvas with a fixed height and a vertical scroll bar. And the canvas has 10 children in a vertical line (like a VBox) whose combined height exceeds the height of the canvas. Based on the scroll bar position, only some of the children will be visible at a time.Is it possible to determine which children are actually visible? Or whether or not a specific child is visible on screen?
View 1 RepliesI have a picture on the stage that has multiple items that have hotspots/links over them that should open a child swf on top of the background and show details about the items. then have a button in the child swf itself that removes the child from over the background so the user can click on another item etc.I found this code in someone's post and I am trying to modify it so that works for multiple swf files...it currently works for a single swf.I wan to pass the name of the button in front of the .swf in the URLRequest to have the same name as the instance name of the referring button. But I can't figure it out. Here is the code I am using on the stage
