Well, I have this Obj which I tell to move using the walk() proc and I want it to is make the Object walk right through it like theres nothing there, whereas other objects are stopped from going through it aswell as mobs.

I have tried to this using the Enter proc which only allows istype(A,/obj/ball) and then I went on to Bump() but still no Success :(

Edit:
Heres an example of an object
obj/Ball
    icon='Ball.dmi'
    density = 1
obj/BallHole //only ball should be able to go through this
   icon='Ball.dmi'
   icon_state = "BallHold"
   density = 1
mob/verb/Shoot(){var/obj/Ball/S = new();walk(S,usr.dir)}


I want the ball to be able to pass through the ball hole and carry on moving but nothing else should be able to.

Uhh...
obj/Ball
    icon='Ball.dmi'
    density = 1
turf/BallHole //only ball should be able to go through this
   icon='Ball.dmi'
   icon_state = "BallHold"
   density = 1
    Enter()
        if(istype(obj,/obj/Ball)) return 1
        else return 0


mob/verb/Shoot(){var/obj/Ball/S = new();walk(S,usr.dir)}


I believe that should work

Look up the Enter() procedure.

Also, ballhole should be a turf, so that Enter() works.

That will not work.

For one, "obj" is not defined...

Secondly, you should use the argument to find out what object tried accessing the /turf.

Third, you should call return..() instead of return 1 - return..() will check if it OK for the ball to move in (ex: checking for other dense objects) - return 1 will allow the object to move in, regardless if there's a dense object already present.

Alright, For your second Point with the Arguments I would prefer using atom in the Argument so that I can define what i want to do with all the types of atoms e.g(area,turf,obj,mob), So that in the future I may be able to do some edits which are not going to take so long.

Doesn't return ..() make it fail every time? I mean if the turf is dense wouldn't that always call bump for obj/ball.

Also he/she should change return 0 to return ..() right? If not the other non dense objects that are not obj/ball would still be blocked.

Exactly what I was thinking anyway thanks for pointing it out anyway.

Using

return ..()


Makes the proc call his parent, in this case Enter(), which by calling ..() the default of the proc happens, which lets the ball pass.

On the other hand, using

return 0 

//or

return FALSE


Makes the proc stop, and not allow that kind of object "Enter()", which in this case, the kind of object is everything except /obj/ball

Incorrect. The default action for a turf that has a density of 1 is to reject other dense objects.

Indeed.

Hm, didn't notice that the turf was set as density = 1... don't know why but meh.
