Accessing Materials(items) from your inventory to build prefabs during runtime

[WillyG99]

Hi!

So if i have a building system, where i open a menu, select my building prefab, and as i try to place it, i want it to check if i have the required materials in my inventory. How can i check something like that? Seems basic and might be obvious but a little pointer would help out alot
