Code:
area
    icon = 'background.dmi'
    density = 0
    Click(var/M)
        new/obj/dirt(M)

obj
    icon = 'terrain.dmi'
    dirt
        density = 1
        icon_state = "dirt"
        New(var/area/M)
            loc = M
            grasscheck()
        proc    
            grasscheck()
                set background = 1
                while(src)
                    world << "Yes"
                    var/nograss=0
                    var/random = rand(1,2)
                    for(var/a=usr.y,a<=64,a++)
                        for(var/obj/T in locate(usr.x,a,usr.z))
                            if(T)
                                nograss = 1
                                break
                    if(nograss==0)
                        if(random == 1)
                            icon_state = "grass"
                    if(nograss==1)
                        icon_state = "dirt"
                    sleep(rand(1,100))
                    grasscheck()
        Click()
            del src


Problem description:

The grasscheck proc isn't even activating. The world << "Yes" thing is just to tell me if it activated or not. Which it didn't! The New() proc isn't even working. How do I fix this? D:

New objects spawned via clicking an area works, but not the ones that are originally on the map!

(Note: I have 64 of this obj on the map.)

EDIT: I changed it to an obj, so might aswell update this.

Try moving the grasscheck() under the obj group. Not under dirt.

It immediately crashes when it reaches the line:

                   for(var/a=usr.y,a<=64,a++)


usr is null, so usr.y returns a "null.y" error. As a rule, usr is not valid in procs. Presumably, you want src instead?
