Hello! O/
So... first, thank you very much for the help, I thought no one could answer me... I think I understood part of your theory ...
Well, I created a new project and put everything in a very simple way...
1 - I put ID's in the Slots using variables and I used the same duplicate sprite 5 times, putting different ID's for each one.
2 - I also put a bollean variable to check if it will be Busy or Not.
3 - Then I put an 8-way behavior on the character so he could move around the scene.
4 - Then I put all the features that the character will pick up, also separating the items from the scene in layers. I hope you understand...
NOTE: Open this image in a new tab, to see better, the site has cut.
Now I need to know if it's more or less as you imagine it, or need to change something?
