trophy (help!)

Just trying to make a working missile defense system. Problem is that the object finder can only target one object before it becomes useless, making the first missile the real defended one and the others are staged for show.

I was hoping someone could improve on this and possibly make an Lua that really targets or just a better targeting system all together? As long was wondering is anyone could show me some cool laser targeting stuff too.

As long I'm back for a brief time again ^.^
