makeing enemies

I am making a game and can’t find out how to make enemies. Can someone please help me out with this ?

[Edit by Berenger : Please try to write in a proper english with a reasonable ponctuation. Seriously, Even your tags are spelled wrong.]

A good starting point is the FPS Tutorial: download the Completed version to see how it works, then do it yourself from start - download the FPS Tutorial and the 3 PDF instructions and follow them - you will learn a lot, and get some amazing enemy robots to kill in your game.
