[Spell] Hero Bag System?

[Knight of Arsford]

I was looking at the Spells section for something like this but they were either too complicated for my map or just not what I was looking for.

The idea is simple and you might know of it already: An invisible hero that acts as a bag or inventory for the main hero. I suppose it goes anywhere the main hero goes as you can swap items with it anytime anywhere.

Any help with how to start it, or simply linking an existing Spell for it would be appreciated.

It’s basically just like you said. Make a hero and give it no model file. Give it the ability called inventory (unit) that is modified to have 6 slots. Make sure it is not a hero inventory so the bag can’t use any of the items. It might be a good idea to give it invulnerability too. I set the selection size to -1.00 so the health bar would disappear. Now you just run a periodic trigger that sets a point at the position of your hero, moves the bag to that point and then make sure to destroy that point to avoid leaks. Every 1 second or so should be enough.
I also added a trigger that runs whenever you select the bag. If you have your hero/heroes selected also it deselects the bag. That’s just so I don’t have them both selected when I drag-select my heroes.
The last thing I did for mine was to add a trigger that detects when the bag is issued an order to pick up an item. I just make sure the bag moves to that item so I don’t have to worry about it not being in range. You won’t need it if you only have one hero though. I can attach the triggers next time I’m on my computer. I’m on my phone right now.

Here's something I threw together.

The Inventory unit is hidden by default, but the Hero has an ability that hides/unhides it and moves it to his position.

Then whenever you order your Hero to pick up an item, I check if his inventory is full, and if it is full then I order the Hero to cast a hidden ability on the target item.

Once this ability goes off I give the target item of the ability to your Inventory unit instead. This is useful because it makes your Hero walk up and "pick up" items even when his Inventory is full.

Note that it's designed to only work for 1 Hero per player. It would need to be expanded upon to work for multiple heroes per player. And the Inventory Unit could be designed to be a Hero as well. Also, I didn't bother dealing with the Memory Leaks but it's not that big of a deal.
