Inventory System

I am going to preface this by saying that I am a beginner at coding and you might need to hold my hand. I am trying to make a inventory system for my game where the only inventory slots are the 10 on the hotbar and 3 or 4 equipment slots (such as clothing). I wish to be able to pick up and drop items from and to the 3d world. I would also like to be able to choose which slot I want the item to appear in by having that slot selected when i pick up a item.

Apologies for the long question and very specific one. I appreciate any help that I get.

 

Watch these to get you started:

You might want to change the Inventory to an array though. Up to you.

 

Thanks I will try that and see if it works. Thanks
