How do I fix my drag and drop inventory?

Hi everyone.

I've been trying to figure out what I'm doing wrong for a few days now, and I still haven't gotten an answer :P

I'm working on an RPG inventory, I created a DRAG & DROP system that works, but there is one big BUT.

All slots in the inventory are the same Inv_Slot object (highlighted in red), I change the appearance of the slots that are supposed to be slots for weapons, shields, etc.

What I was able to achieve looks like this, and it works:

However, a problem arises when I want the right type of equipment to go into the right slot, for example, it's a weapon that is known to go into a weapon slot, when you put it into another slot it goes back into the inventory, or when you put the wrong type of weapon into a slot, the same thing happens.

I've tried many solutions but can't figure out how to solve it. If someone would be so kind and suggest what I am doing wrong and guide me to the right way of thinking.

Thank you

You'll need variables on the invslot for type and also on items for type. Then it is just a case of adding more conditions to your drop event. I would probably split them out by type so they don't become convoluted so one event is for weapon item on dropped so this only handles weapons : on items dropped (items.type=weap), sub events if invslot.type=weap and is not full then drop it, Else if invslot.type not equal weap or is full, then send it back. Then you can create a different event for drop items if item.type=armour etc
