Hello Again!
First of all thank you! The inventory system code was not so clear to me, but it worked perfectly, in time I know I'll understand. I thank you for your patience, I apologize for any inconvenience and I will be more than happy to help.
I made a simple build of the prototype that already has ready, who wants to check how it was, feel free to test the link below. If there is a bug, feel free to report it too, I'll be happy to correct it.

OBS: Apologies for my English, I know it is not very good. But with everything it gave you to understand xD
Thank you again!
