im trying to code a combat system...its not necessarily like any combat system thats been done in the past and im not really sure how to go about it.

what variables should i define?
how should i start?

a few questions:
what keywords do i use to describe enemy dist. from player i want to use that for something.

when the enemy comes into the "fight area" the camera changes...how do i move the camera to a certain spot.

player walk animation needs to change while fighting...how do i change is walk animation

music doesnt change...i dont feel the need for it.

i just want to know some keywords to use when trying to do these things...i cant hire some one to help me...no money...im working alone now, my collegue went off to college. im completely swamped. the magazine was moving along steadily but ive had to slow down and work on the game and magazine at the same time. so the magazine is still coming just taking some time...if anyone wants to help me out and be a freelance scripter thatd be great even though i dont think thats likely. but for now just need those key words.
