mob/Player/Stat()
    if(src.islocked == 0)
        if(istype(src,/mob/Player))
            while(src)
                sleep(8)
                src.overlays-=src.HealthOverlay
                src.overlays-=src.MagicOverlay
                src.Bars()
                src.ExpBar()
                statpanel("Stats")
                //the rest


however thats keeping my stat panels from showing up i think its the while(src) is there another way or a step to fix this problem?

Eh? Why are you updating the statpanel like that? Simply use the parent procedure.

because i want it setup like that, so is there a way to fix my problem or not?

Stat() automatically is called every few ticks. No need for a while().

So if i remove while(src) i should be set?

:EDIT:

mob/Player/Stat()
    if(src.islocked == 0)
        if(istype(src,/mob/Player))
            src.overlays-=src.HealthOverlay
            src.overlays-=src.MagicOverlay
            src.Bars()
            src.ExpBar()
            statpanel("Stats")
            //the rest


I want it to remove every single layer that is attatched to HealthOverlay + MagicOverlay when its called how can i accomplish this because the way i have it now only removes two.

mob/proc/Bars()
    new /obj/healthbar(src)
    for(var/obj/healthbar/H in src.client.screen)
        var/Length=30
        var/Percent=round(src.Health/src.MaxHealth*Length)
        H.icon_state = "[(Percent>Length)?(Length-1):Percent]"



obj
    healthbar
        icon = 'meter.dmi'
        icon_state = "29"
        New(client/c)
            screen_loc="10,10"
            c.screen+=src
            world<<"I have been called"



I get this runtime error
runtime error: undefined variable /mob/Player/var/screen
proc name: New (/obj/healthbar/New)

this is line 15
    for(var/obj/healthbar/H in src.client.screen)

and this is line 27
            c.screen+=src

</dm>
how do i fix this runtime?

lemme take a stab at it.

the first one is because there is no client?
maybe you should add a line before doing the loop
if(!src.client) return

the second one, u didnt show us where u are defining c?
and im guessing you have c as a /mob/Player
define c first
var/client/c
c.screen += src


just a try ;) might be wrong.
