Equip System

[noviceboy55]

There's 2 systems I am looking for here.

1. The system whereby the player will have 2 inventories. ( Switching between them either with the Esc key or an ability )

2. The system whereby your only allowed to equip 1 of each type of item. ( Like you can only wear 1 head armor, 1 platemail, 1 weapon, 1 shoe, 1 gloves etc.... )

Your going to have to use JASS for the 2 inventories. You can use GUI triggering for the equipment. You would have to import either a custom 12 slotted inventory that'll show up or create a hidden hero that is clickable that has another 6 slots.
You should check out hiveworkshop spell section for importing these systems.
