Opposite of this.

How would I change this code to make it an else if then the opposite of this code?

                    if(M in get_step(usr,usr.dir))


I tried
if(!M in get_step(usr,usr.dir))


and

if(M in !get_step(usr,usr.dir))


But they didn't work.

You may want to look up turn() 
if(M in get_step(usr,turn(usr.dir,180)))
turn() returns the dir 180 degrees, which is the opposite.

It should be mandatory to run at least a quick search before posting. [link]

...It worked but what I was hoping to get fixed didn't get fixed, because for some reason when my character is next to a person he attacks but it doesn't subtract health and doesn't do anything to the opponent.

If you want to find a mob in a turf, use locate():

var/mob/M = locate() in get_step(src,dir)


Do NOT loop through every single mob in the world and check its location.
