Your code works fine as is. But I'm curious too see how it will perform with the hundreds of objects you mentioned. Don't get me wrong every programmer needs to do things their own way, but it seems to me that using your current method, there is a lot of required code to produce a simple result. Are you trying to create some kind of scriptible AI? I still think there is a simpler way to achieve the same effect. If I get some time I'll post some code.
