I know how to make an obj go moveing(useing walk). That is not the problem.
Heres what i did:
turf/grass
    name = "Grass"
    icon = 'Landscapes.dmi'
    icon_state = "grass"
    Entered()
        view(src)<<"usr = [usr], src = [src]" //To show the grass and entered for testing only.
        if(istype(usr,/obj/SandWave)) //usr is person(or object) entered
            flick("sand",src) //src is the grass
        else
            view(src)<<"Aww" //Just to test.

Whenever i, myself went in, the usr came as me.
But when i sent the obj in, the usr was 0(null).
How would i fix it to know when the Sandwave is comeing?(Replaceing 0 with sandwave)
And only for sandwave nothing else.

The thing that Entered() the turf has to be defined like so

turf/grass
    name = "Grass"
    icon = 'Landscapes.dmi'
    icon_state = "grass"
    Entered(atom/movable/A) //A would be the thing that Entered() src (the turf)


Then you can run istype() and ismob()/isobj() etc checks.

turf/grass
    name = "Grass"
    icon = 'Landscapes.dmi'
    icon_state = "grass"
    Entered(atom/movable/A) //A would be the thing that Entered() src (the turf)
        if(istype(A,/obj/SandWave))
            flick("sand",src) //src is the grass


If you later want to actually use the obj, it's probably worth doing var/obj/O = A after if(istype()) because that gives you access to the obj variables.

I would recommend looking up what usr is, you seem to be confused.

Well if you know what usr is, why would you even consider doing the following?

if(istype(usr,/obj/SandWave)) //usr is person(or object) entered


Your comment, "usr is person(or object) entered", is incorrect. And doing istype(usr,/obj) just doesn't make sense.
