(See the best response by Kozuma3.)
Code:
obj
    Amaterasu1
        icon = 'Amaterasu.dmi'
        density = 1
        pixel_x = -4
        pixel_y = -4
        Bump(A)
            if(ismob(A))
                var/mob/M = A
                var/damage = src.Ninjutsu
                if(damage >= 1)
                    var/mob/O = src.Fowner
                    M.health -= damage
                    view(M)<< "<b><font size=1 face=verdana color=red>[M] was hit by [O]'s Amaterasu for [damage] damage!!"
                    M.overlays+=/obj/AmaterasuBurn/
                    M.inamat = 1
                    src.loc=locate(101,101,1)
                    End
                    if(M.inamat==0)
                        M.overlays-=/obj/AmaterasuBurn/
                        M.inamat = 0
                        del(src)
                        return
                    else
                        M.health-=M.maxHP/6
                        M<<"Amateratsu burns your body."

                        if(M.health>=0)
                            sleep(60)
                            goto End
                            
                        if(M.health<=0)
                            M.health=0
                            M.Death(O)
                            M.overlays-=/obj/AmaterasuBurn/
                            M.inamat = 0
                            M.inamat2 = 0
                            del(src)
                            return

            if(istype(A,/turf/))
                var/turf/T = A

            if(istype(A,/obj/))

Problem description:
I've been trying to attach a poison like effect with the projectile. Never got the loop to work. I have no idea where to go from here.

I myself would make the poison effect its own proc :P
mob/proc/Poison(time,damage)
    spawn() while(time)
        sleep(10)//1 second
        time-=10
        src.Health -= damage

So like I'll insert it as M.Poison(something)?
Apr 17 2013, 6:32 pm
Yes.

M.Poison(60,4)
//6 seconds.
//4 damage per second.

Okei thank you! And that was a really quick reply! xD
Apr 17 2013, 6:35 pm
Also, you could probably use that procedure for alot more than just poison :P
Apr 17 2013, 6:37 pm
Ah~ like what? :o Just curious.
Apr 17 2013, 6:39 pm
Renaming the procedure to Effect, it could be used for Poison, Burn, and other types of harmful effects.
Apr 17 2013, 6:43 pm
Ah! I see, useful indeed ^^

If ever though, how can I stop it. Like with antidote or extinguish.

You would need a check for that.

Example:
if(!is_poisoned && !is_burned) return 0

//  Or a format you may be familiar with (though not as robust):
...
if( (is_poisoned == 0)  &&  (is_burned == 0))
   return 0
...continue on...


The ! checks for the values 0, "" and null, which are the false Boolean values in BYOND; true being anything else.


Edit: Another safety check you want to do is that, before starting the loop, check if the person is already poisoned at the beginning. Otherwise that person will get killed a lot faster due to the more damage from the proc being called & running more than once

Ex:
mob/proc/Poisoned()

   if(is_poisoned || is_burned)   return 0
/*

Stop the procedure if the person is already poisoned/burned.


By the way, that is how you check for true Boolean values: 
if(x) == if( x != false ) == if( x == true)

For checking the false values (0, null, ""):
if(!x) == if( x == false ) == if( x!=false)

if() evaluates to see if the statement is true. ! is essentially an inverse of false <--> true

*/

while/for ...     //  Start constant damaging

    if(!is_poisoned  &&  !is_burned) return 0
//  Stop the procedure if the person is no longer poisoned nor burned

    ... do poison stuff ...

To sum it up, setting a mob's stop_effect to true will stop the effect proc on the next recursion.
mob/var/stop_effect=0
mob/var/is_effected=0

mob/proc/Effect(time,damage)
    if(is_effected)return
    src.is_effected=1
    while(time)
        sleep(5)
        if(stop_effect)break
        time-=5
        src.health-=damage
    src.is_effected=0
    src.stop_effect=0

Going off of the current solutions, it would be best to offer a "delay" argument to sleep by instead of 5 or 10.

Maybe. Mine was more-so for example.
