I am making a platform game and I want enemies to pefrom a certain action (any action) only when they are visible on the view. Can some one send me the code foe that.

Also I want my shooting baddies to shoot the player only when he is about 200 pixels away on both sides. How is that done.

NOTE: Even though I know I'm not suppose to use the blog to brag, This is a powerful way to get people to help rather than using the forum
