Thank you again for your amazing example!
I implemented the system from your example in my project and tried it out. Something happens, but not exactly what I want .
The only thing that was changed is that I have 2 different types of slot objects. One for the inventory and one for the chest. Because I wanted the inventory slots to be next to the chest slots. So I thought that I simply have to duplicate it for the chest and the inventory.
I put some screenshots of my events below. If that's not enough, please tell me and I'll send you my capx.
