So after updating my whole combat system from a tutorial, everything worked fine but I noticed that when you are facing a certain direction (both NPC and player), they start attacking themselves. My NPC monsters tend to kill themselves A LOT and its really annoying. Its always a different direction every time, so like when im facing north and I attack I start doing damage on myself. Same thing with the monsters. I can't find the problem.. hopefully someone here can see it. Here is all of my code containing something to do with the combat:

mob/Enemies/New()
    src.HP=src.MaxHP
    spawn(-1)    src.CombatAI()
    return ..()

mob/Enemies/proc/CombatAI()
    while(src)
        for(var/mob/Player/M in oview())
            if(get_dist(src,M)<=1)
                src.dir=get_dir(src,M)
                src.Attack()
                flick("attack",src)
                sleep(rand(20,40))
            else
                if(get_dist(src,M)<=2)
                    step_to(src,M)
                    flick("walking",src)
            break
        sleep(rand(4,8))

-------------------

mob

    verb
        Attack()
            flick("attack",src)
            for(var/mob/M in get_step(src,src.dir))
                var/Damage=rand(0,str)
                view(M)<<"[src] hit [M] for [Damage] Damage!"
                M.TakeDamage(Damage,src)

--------------------

        DeathCheck(var/mob/Killer)
            if(src.HP<=0)
                if(src.client)
                    world<<"[Killer] Killed [src]!"
                    src.HP=src.MaxHP
                    src.loc=locate(5,5,1)
                else
                    Killer<<"You Killed [src] for [src.exp] Exp"
                    Killer.exp+=src.exp
                    Killer.LevelCheck()
                    del src
        TakeDamage(var/Damage,var/mob/Attacker)
            src.HP-=Damage
            src.DeathCheck(Attacker)

Wrap the code in <dm>code here </dm>

If you're utilizing pixel movement, then it's possible to hit yourself because you can occupy multiple locations at a time when you're offset between them. You'll want to add a check to make sure you're not hitting yourself, or just disinclude whatever's attacking from the list of possible targets.

How would I disinclude the attacker from attacking himself? Sorry, I'm pretty new to all of this and still learning a bit about all of this

In your for statement, you could do:

for (var/mob/m in get_step(src, dir))
    // If the mob is the thing attacking, skip over hitting it.
    if (m == src) continue

    // damage stuff goes here.
