Steve, I suggest you read up on eventListeners in Actionscript 3.
I provided an example that dispatches a new event called "what text", it doesn't pass that as a string to another function. I did this because you are creating your movieClip within a function so it's scope will only be within that function...so I added the eventListener to that movieClip to listen for the dispatched event named "what text". "DrawTheMainScreen - These are the items on the stage that stay all the time." If they are on the screen at all times then you would want to declare those outside of that function first so that they can be referenced in other places....right? * It sounds like you want to display a bunch of objects on the stage that are available at all times. So with that said you'd want to write the vars for those objects outside of your function....THEN when you call DrawTheMainScreen it sets what those objects are. Now when you click on that button your click event can fire an event that can reference anything that is on the stage*. *see my first code example. Let me know if you're still unclear and I'll send some more code. -Gerry On Apr 22, 2011, at 10:24 AM, Steve Abaffy wrote: > Well my basic understanding of programming goes something like this. > We call functions to do certain things when we need them to do it, so: > Basic flowchart of program. > > LoadExternalData - This data will be loaded into movieclips to be place on > the stage at a later time. > DrawTheMainScreen - These are the items on the stage that stay all the time. > DrawNavigationButtons - These buttons will load the different things on the > screen that change.
