So I've made sure that my attributes are integers in the right spot and that they're added as Status Attributes with the right spelling, but only some of them will show up with the numbers added into the attributes integers.

The status bar looks like this:

HitPoints: 5
Damage: 0
Attack: 0
Armour: 1
Defence: 0

NOTE: None of them should be 0 as I set them all at 1 just to take a look. The player's code is below. For reference, I've started trying to put together the excellent Zombie Combat code described here: https://github.com/ThePix/quest/wiki/The-Zombie-Apocalypse-(on-the-web-version)

I should also add that I've changed attack and damage in all the other code to Attack and Damage so it would show up in the Control panel properly.

Okay, I solved it ... the Initialisation Script trumps what I put in the attributes section. Silly me!

All right new issue that may relate to the above code so posting it here ... I've got the zombies following, I've got them attacking and I can attack back, but it's not changing the player's hit points. It counts down the zombie's hit points but when they hit 0 it just says They're Dead but they keep moving (in other words it's not changing their dead to true).

THE DO ATTACK FUNCTION.  Please note I replaced weapon with attacker because I don't want to include weapons.

````  <function name="DoAttack" parameters="attacker, weapon, target"><![CDATA[
    roll = GetRandomInt(1, 10) + attacker.Attack - target.Defence
    Damage = DiceRoll(attacker.Damage) * (100 - target.Armour) / 100
    if (Damage < 1) {
      Damage = 1
    }
    if (roll > 9) {
      Damage = Damage * 2
      msg (CapFirst(attacker.alias) + " attacks " + target.alias + " and gets a critical (" + Damage + " Hits)!")
      target.HitPoints = target.HitPoints - Damage
    }
    else if (roll > 4) {
      msg (CapFirst(attacker.alias) + " attacks " + target.alias + " and hit (" + Damage + " Hits).")
      target.Hitpoints = target.HitPoints - Damage
    }
    else {
      msg (CapFirst(attacker.alias) + " attacks " + target.alias + " and misses...")
    }

And Solved ... not sure what the error was but I was fresh in that I just re-did it in a fresh area and got it working. I'd delete the thread buuuuut it doesn't look like that's a thing.

Same error as the first one.
Your initialise script was setting the changedHitPoints script to:

        if (zombie.HitPoints > 0) {
            msg ("Hit points now " + zombie.HitPoints)
          }
          else {
            msg ("It collapses, dead!")
          }

which prints a message to say it's dead, but doesn't set the dead attribute. If you change script attributes during the game, you need to remember that it will only execute the latest version.

This is what my start script looks like.
