Thank you blackhornet, the problem was with this Inventory the object don't spawn at specific slots, they spawn randomly.
So the object can be one moment at X=1 and another moment at X=9 =s ...
Then is there a way for specify it =s ...
Exemple :
The Object Sword have the ID_3 and is on the Slot 4 ( X=3 ) one time after it was at Slot 1 ( X=0 ) so how can i get at evry time is position ( X=... ) for apply the At(X,Y) =s ...
Thank you =)
