I'm making an RTS game for Christmas called Santa vs. the Snoman. The inspiration from this game came from the movie Steve Oedekerk's Santa vs. the Snowman 3D.

I just finished up the path finding for a ranged unit. took some effort. I tried creating a radius but there was a lot of complications so I decided to go with an invicible circle and just hit test it. The down side is it is takes up more bytes and is a teeny bit harder on the computer but all this kind of stuff adds up.
