Funkyfranky, I think I understand the problem.
But, there is a function that ist called " bomb in zone" or something like that in the mission editor. So, maybe to use something like zones around one target (0-5m, 5-10m, 10-15m....). When it's possible to detect a bomb inside a zone in the mission editor, why not in Moose?
BTW does somebody know how to create moving zones in Moose?
