Could you clarify what exactly seems to be the problem? Have you tried writing simple information to a .txt file instead of an .xml? I know they are basically the same, but I don't know of the write command handles .xml files well. Furthermore, the program could get stuck in a loop with the while command. Replace the while loop with an if statement. If that does not solve your problem, please specify your problem.

Here's my full code. Right now when it runs it's making separate xml files for every second the avatar is in view. What i'm trying to do is everytime the avatar walks into view I want to write the coordinates to separate xml files but only once each time he's in view. and If a new avatar comes into view I want to it make another xml file. if that makes any sense...
