Need Help w/ Auto Item Pickup

[sentrywiz]

Hi.

I am making a hack n slash, simple to the bone arena. In it, I want units to not click on items on the ground in order to acquire them, just to be near them. That being said, I have:

-9 regions
-7 items
-each region spawns a different item (or example, 2-3 regions spawn same kind of item)

I am having issues figuring out:

1. trigger-wise, don't have ideas on checking the range between the unit and the item there.

2. trigger-wise, don't have ideas on checking if the unit already has the same item so he can't pick it up

3. i have one inventory slot allowed, to deny players more than one item being used at a time. and with this, I need the item to be dropped, removed first before the new one picked up.

---------------------------

Please post in GUI-like triggers only. I don't fully understand jass. Thank you

The size of the region affects the auto pickup range. Note that if you drop an item, it can be automatically picked up again. There are ways to prevent that if needed. Add all heroes to the hero group at map initialization or when they are created. You can decrease the loop time to make the triger check the items more often, but don't make it too low like under 0.1 seconds.
