Learning: "How to store items"

[Black_knights55]

Hey,
I was trying to script some "materials" for a crafting system and I have no idea how I could "store" them in the player. Do I have to use clientr. or should I use something else since I would like to have lots of differents "materials" ? I want them to store the "type" (minerals, ingots, logs, etc), the "name" (iron, silver' gold, etc), the "images.png" of the material and the quantity.

Is there a way to put all that in a single clientr. and how can I access the quantity or any other variable with another script? Or is there something else better than clientr. ? Or maybe just a better suggestion how to do it?

Thank you!
