I had some trouble understanding the Tile funcrtion too. I'm still not too swift with it.
There is some information in the docs about tiles, but it still left me a bit confused. You can find that information here:
Game Editor Pro\Docs\gettingstarted_theactorcontrolpanel.htm
Another link that might help you clarify things is:
http://game-editor.com/forum/viewtopic. ... ight=tiles
Finally, if you haven't already looked at the tutorial in GE under "Getting Started"--> Build the senario with Tiles, it might help you.
Sorry if this isn't what you are after. I just wanted to try and give you back a little in return for your help with my "get actor state" question...
