How can I make an obj do something when it gets bumped.

Is there a way I can use bump on an object and if not is there another way to make something happen when you go in contact with it?

The atom's Bump() procedure can do what you want.

atom
 Bump(atom/Obstacle)
  world << "[src] bumped into [Obstacle]"


As you can tell, when a movable object attempts to move, and something stops it from doing this, it will call the Bump() procedure with the argument as the object that stopped them from moving.

A common use is:

atom
 Bump(atom/Obstacle)
  Obstacle.Bumped(src)

 proc
  Bumped(atom/Bumper)
   world << "[Bumper] bumped into [src]."


Using the Bumped() procedure, any object can have their own action when they're bumped.

Can you tell me why this doesn't work?
obj
    butterfly
        icon = 'player.dmi'
        icon_state = "magic butterfly"
        liveforever = TRUE
        density = 1
        isobj = 1
        var/mob/M
        New()
            . = ..()
            spawn()
                move()
        proc/move()
            while(src)
                step_rand(src)
                sleep(10)

        Bump(mob/M)
            M.hp = M.maxhp
            M << sound('sound/heal.wav',,,1,100)

Why is there a variable on the object called /mob/M?
I'll assume it's confusing priority.

Cause I copy pasted it from my enemies code. took out the attack and the move towards usr. I just forgot that.

btw removing that still doesn't make it work

step_rand() doesn't count dense areas as areas it can step to, meaning it doesn't attempt to.
step() does, however.

well it works now but it only works when the obj bumps into me not when I bump into it... How can I change that?
