Code:
mob
    monsters
        Move(var/turf/NewTurf,var/StepDir)  //Move() is built-in
            switch(StepDir)
                if(NORTHWEST)   pick(step(src,NORTH),step(src,WEST))
                if(NORTHEAST)   pick(step(src,NORTH),step(src,EAST))
                if(SOUTHWEST)   pick(step(src,SOUTH),step(src,WEST))
                if(SOUTHEAST)   pick(step(src,SOUTH),step(src,EAST))
                else    return ..(NewTurf,StepDir)
        New(/**/)
            spawn(-1)    src.CombatAI(/**/)
            return ..(/**/)
        MouseEntered(/**/)
            src.AddName(/**/)
        MouseExited(/**/)
            for(var/I in src.overlays)
                src.overlays-=I
        proc
            CombatAI()
                while(src)
                    for(var/mob/player/M in oview(/**/))
                        if(get_dist(src,M)<=1)
                            src.dir=get_dir(src,M)
                        else
                            step_to(src,M)
                        break
                    sleep(rand(4,8))
        EarthMonsters
            icon='Monsters_1.dmi'
            Rabbit
                icon_state = "Rabbit"
                race = "Rabbit"
                hp=10
                maxhp=10
                level = 11
                exp = 172
                dodge=1


Problem description:
My goal was to prevent AI from walking diagonally. But the problem is that when monster is facing client(player) it could be diagonally sometimes. Any help would be appreciated!

Not sure if this work, but just a suggestion D:
var/next_dir = get_dir(src,M)
switch(next_dir)
    if(NORTHEAST){src.y+=1;sleep(5);src.x+=1}
    if(NORTHWEST){src.y+=1;sleep(5);src.x-=1}
    if(SOUTHEAST){src.y-=1;sleep(5);src.x+=1}
    if(SOUTHWEST){src.y-=1;sleep(5);src.x-=1}

EDIT
I also, think it shud be placed under the Combat_AI() procedure

            CombatAI()
                while(src)
                    for(var/mob/player/M in oview(7))
                        if(get_dist(src,M)<=1)
                            src.dir=get_dir(src,M)
                            var/next_dir = get_dir(src,M)
                            switch(next_dir)
                                if(NORTHEAST){src.y+=1;sleep(5);src.x+=1}
                                if(NORTHWEST){src.y+=1;sleep(5);src.x-=1}
                                if(SOUTHEAST){src.y-=1;sleep(5);src.x+=1}
                                if(SOUTHWEST){src.y-=1;sleep(5);src.x-=1}
                        else
                            step_to(src,M)
                        break
                    sleep(rand(4,8))


It works, but if you go down or up while monster is facing you he will teleport right in the middle of the player icon :)

if(NORTHEAST){step(src,NORTH);sleep(5);step(src,EAST)}
if(NORTHWEST){step(src,NORTH);sleep(5);step(src,WEST)}
if(SOUTHEAST){step(src,SOUTH);sleep(5);step(src,EAST)}
if(SOUTHWEST){step(src,SOUTH);sleep(5);step(src,WEST)}

I believe this will work, since it auto-detects collision when using step(), in other words, if there is an obj with density. It'll actually collide

When monster is facing player, he starts to move North, East or West randomly.
