(See the best response by Albro1.)
Code:
mob/var/list/hot_slots=list()
mob/proc
    SaveSkills()
        for(var/Skill/S in usr.client.screen)
            if(S)
                hot_slots[S] = S
    LoadSkills()
        for(var/Skill/T in usr.hot_slots)
            if(T)
                src.client.screen += T


Problem description:
Well i tried to make an hot key slots (0-9), it's worked but the problem is when i trying to save it, it's gives me an error (well the save works)
runtime error: Cannot read null.screen
proc name: New (/obj/Huds/Slots/Hud5/New)
  usr: null
  src: Hud5 (/obj/Huds/Slots/Hud5)
  call stack:
Hud5 (/obj/Huds/Slots/Hud5): New(null)

i tried to fix it, but it just won't work..

Don't use usr in procs. Use src.

usr is what called the proc - in which case, usr could even be another proc.
src is the source of the proc, which is the mob.

This error isn't even in SaveSkills().

Your error is in /obj/Huds/Slots/Hud5/New().

The error is in the HUD's New() proc. I'm not sure what is so hard to understand about that.

You are doing something with a .screen variable and the source you are using for it ends up being null. Post the HUD's New() proc.

i do understanding it bro,
but the problem it's above to the key i setted ! if i set 4
it's will display Hud5 error, if i setted 1 that's display Hud2 error !

You are calling New() somewhere in your code and you aren't sending a client to the argument.

When are you calling mob.Hud()?

Is there anywhere else you are calling the New() procs for this?

Does the mob that you're calling it on have a client set? Many people will create a secondary mob during character creation, and then only assign the client to it at the end (so if you're doing this as well, and you called Hud() on that secondary mob, it might not have the client set yet).

Anyways, show us the code where you're calling Hud().
