So I was trying to make a new game with ThePixie's zombie tutorial. For some reason, when I copy and paste the game in there now, it won't equip right. The listalias isn't displayed, and all it says is equipped. Then when I unequip it and try equipping it again, the name has disappeared completely, and it won't equip. The same thing happens when I try pasting from my Zombie 2 game. The weird thing is, this doesn't happen when I'm using my zombie 2 game.
Any help is appreciated. I just want to equip and unequip items without my items disappearing.

I'd also like help with these healing commands, as I still can't get it to work. (Not when it's in an item object space, and not when I type it out)
Heal Potion #object#
if (player.potion > 0) {
if (player.hitpoints < player.max) {
player.hitpoints = player.hitpoints + 60
}
}

Heal Hyper Potion #object#
if (player.hyper_potion > 0) {
if (player.hitpoints < player.max) {
player.hitpoints = player.max
}
}

your code works fine...
but after you drink the potion, you need a check to see if player.hitpoints > player.max

It turns out I was messing with the code and deleted a few variables for the player.max.

As for the item glitch, this might just be a computer error with quest.

This is what it looks when it's equipped.

It happens... been there too many times my self...

Sorry. I've been working on it for days and I can't figure out what the problem is.

you aren't displaying its alias...

to display it's alias:

when equipping/equipped:
this.default_alias = this.alias // for example: this.default_alias = "katana"
this.alias = GetDisplayAlias (this) + " (equipped)" // for example: this.alias = "katana (equipped)"

when unequipping/not-equipped:
this.alias = this.default_alias // for example: this.alias = "katana"

here's Chase's 'wearables' library:

ask if you got any questions

Fixed it. (Changed listalias to alias)
