how do i make it so when the usr gets within 1 tile of an obj his/her str gets decreased by one every 2 seconds

for grass you could do someting like this

turf
grass
icon = 'grass.dmi'
Entered()
usr.hp -= 2
sleep(20)
Exited()
usr.hp == usr.hp

something like that... but you have to get it to repeat somehow.

mob/var/onturf = 0

turf/onetileawayturf
Entered(O)
usr.onturf = 1
usr.str += 2
usr.srgiven()
Exited(O)
usr.onturf = 0

mob/proc/strgiven()
if(usr.onturf == 1)
sleep(20)//2 seconds.:/
usr.str += 2
usr.strgiven()
else
..()

This is really horrific, for two reasons:

  • NEVER use usr in Entered() or Exited().
  • usr.hp == usr.hp does absolutely nothing because == is a comparison operator. If it was just =, it would still do nothing, because you're only setting the value to itself.

Egads, SS, how many times do I have to tell you this? DO NOT use usr in Entered(). In this case, the correct var would be O. You'd have to cast it to a mob first, though, like this:
turf/onetileawayturf
  Entered(atom/movable/A)
    if(ismob(A))
      var/mob/M=A
      M.onturf=1
      ...

mob/proc/strgiven()
if(usr.onturf == 1)
sleep(20)//2 seconds.:/
usr.str += 2
usr.strgiven()
else
..()

This should be src, not usr, because the proc belongs to the mob it's happening to. During the sleep period, usr could change to something else.
Also, you have to use spawn() to call strgiven() again, or else you'll eventually overflow the stack because the same proc keeps calling itself recursively.

obj/Thingy
proc
Weaken()
for(var/mob/M in oview(1))
M.str -= 2
spawn(20) Weaken()
New()
spawn() Weaken()

I have no idea why everyone else was using Entered and Exited...
