Health Bar

I want to put a health bar into my game but have very little knowledge on how to do it. I know that I need an icon with different icon states for it. I got that. Now how do I make the icon show up as the health bar? This brings up another question. How do i incorperate icons into a stat panel? I don't plan on putting the health bar over the character, but having it in a stat panel.

Make a new object, set the icon's object to the health bar icon, and put the object in the statpanel.
client
    var/obj/health_bar/health_meter
    New()
        .=..()
        health_meter = new
    Stat()
        statpanel("Stats")
        stat(health_meter)

obj/health_bar
    icon = 'health bar.dmi'

You could set the health_meter's icon_state in the Stat function if you wanted to take the easy way out, but I would suggest you change it after every time the client's mob's health is changed.

How do I make a proc that will update the health bar depending on how much health the user has (I want it to check every time the user gets attacked and takes damage).

Nevermind. I figured it out

If the icon states for the health meter are numbered 0 or 1 through the number of states, then you can just use a formula to grab the appropriate one. health/max_health*max_state. max_state is, of course, the highest numbered icon state. So, if you use an entire icon and have a meter go up or down by a pixel every time, you would probably have icon states numbered up to 32. In such a case you would do health/max_health*32.
mob/proc/update_meter()
    if(!client)return 0
    client.health_meter.icon_state = num2text(health/max_health*32)

Then you could call it wherever health is changed.
mob
    verb
        attack(mob/M in oview(1))
            M.damage(1)
        first_aid(mob/M in oview(1))
            M.heal(1)
    proc
        damage(N)
            health = max(0, health-N)
            update_meter()
        heal(N)
            health = min(max_health, health+N)
            update_meter()
    Bump(atom/movable/M)
        if(istype(M, /obj/spiked_trap))
            damage(1)
turf/magic_pool
    verb/drink()
        set src in view(1)
        usr.heal(1)

Now I have a new problem. It seems the way it's set up it's affecting everyone (modifying everyones health bar when someone gets attacked). The code is as follows:
client
    var/obj/health_bar/health_meter
    New()
        .=..()
        health_meter = new
    Stat()
        health_meter.name = "[usr.health]%"
        statpanel("Status")
        stat("Name:","[usr.name]")
        stat("Health:",health_meter)
        stat("Chakra:","[usr.chakra]/[usr.totalchakra]")
        stat("Title:","[usr.title]")
        stat("Strength:","[usr.strength]")
        stat("Defence:","[usr.defence]")
        stat("","----------------")
        stat("Money:","$[usr.money]")

obj/health_bar
    icon = 'health bar.dmi'
    icon_state = "full"

mob/proc/HealthCheck()
    for(var/obj/health_bar/health_meter)
        if(usr.health > 90 && usr.health <= 100)
            health_meter.icon_state = "full"
        if(usr.health > 80 && usr.health <= 90)
            health_meter.icon_state = "90%"
        if(usr.health > 70 && usr.health <= 80)
            health_meter.icon_state = "80%"
        if(usr.health > 60 && usr.health <= 70)
            health_meter.icon_state = "70%"
        if(usr.health > 50 && usr.health <= 60)
            health_meter.icon_state = "60%"
        if(usr.health > 40 && usr.health <= 50)
            health_meter.icon_state = "50%"
        if(usr.health > 30 && usr.health <= 40)
            health_meter.icon_state = "40%"
        if(usr.health > 20 && usr.health <= 30)
            health_meter.icon_state = "30%"
        if(usr.health > 10 && usr.health <= 20)
            health_meter.icon_state = "20%"
        if(usr.health <= 10)
            health_meter.icon_state = "10%"
        if(usr.health == 0)
            usr << "<font color = red><b>You were beaten to the brink of death! Luckly you escaped just in time, but you have to be more careful!"
            usr.loc = locate(77,77,2)
            usr.health += 100
            health_meter.icon_state = "full"

The for(var/obj/health_bar/health_meter) is what's doing it to you. Looping through them with a for-loop is going to loop through all of them that exist. What you want in that situation is just client.health_meter.
