Finished the first Level

Today I completed my first level and began coding my character, including his walking, where he can and cannot access and the models of the undead characters, I'm having a little trouble coding how the zombies will know to approach the character and how to get the character to fire where he is pointing. My primary idea is have two sets of controls one on the mouse the other on the keyboard,. the WASD keys will control where he'll walk, and the mouse will control where he'll shoot.
