how would you make a explosion where it would make the ground it explodes on a circular shape of dirt afterwordslike bare miniumim coding kind of code cause i suck when it come to some super complex code

make some dirt icon then find out location of explosion use
for(var/turf/T in oview(5))
T.icon_state="Dirt"icon_state

true that works but it makes more of a square then a circle

How about you simply do this?
var/range=6
for(var/turf/T in range(range,src))
    if(sqrt((T.x-x)**2+(T.y-y)**2)<=range)
        T.icon_state="dirt"

I dug this out of one of my projects:

proc/Distance(atom/M,atom/N)
    return sqrt((N.x-M.x)**2 + (N.y-M.y)**2)

proc/GetRing(atom/M, radius) //Abyss Dragon's, it didn't come in a library.
    var/ring[] = list()
    var/turf/T
    for(T as turf in range(radius+1,M))
        if(abs(Distance(T, M)-radius) < 0.5)//The < 0.5 check is to make sure the ring is smooth
            ring += T
    return ring


Notice my comment with the code says where it came from. I try to do that so if I ever have a situation like this I can say whose it was. I've used this proc before and it's brilliant! Couldn't ask for a smoother ring. You'll have to play with it to fill in the whole circle though.

I was using this code to make a sort of druid ring dynamically. Then I decided on something a bit more simple and scrapped it, but I still have the code:
proc/findspot()
        var/turf/t = locate(20,20,3)
        //var/count = 0
        for(var/turf/x in GetRing(t,5))
            if(x.density)

                continue

            else
                for(var/atom/y in x.contents)
                    if(y.density) break
                    src.dir=get_dir(x,t)
                    src.Move(locate(x))

Or he could just make one big crater image and offset it.
But this is more of how to make a multi-tile crater effect, not a circular explosion.
