OK, thamks to a hell of a lot of help my map is coming along and is nearly done.
I have just finished carefully placing info_nodes around my level so the enemies can run around etc, thr trouble is that the enemies all blow themselves up inside the house.
I have them set to be triggered when they see the player, but by the time the player gets upstairs in the house, 2 or 3 are already blown up!
I`ll post the map for you guys once its done, considering how much help you have all been
Thanks again.
