[1.19.2] about "ForgeCapabilities.ITEM_HANDLER" preload a container whit custome loot

perromercenary00 · February 2

good nights

this one is a little hard to explains

i finally managae to get working the briefcase i still working whit the block part but still

back in the 1.8 the idea whit this briefcase was to give the player an initial inventory soo ineed to preload the briefcase whit items from code digginup in the code

i know minecrfas store inventories like nbt data usig a listtag named "Items" so i copy paste code from the chest container class to load things to mi briefcase but notice mi briefacase "ITEMS" and the "ITEMS" in the GUI dont match
looks like to separate sets of nbt data

both sets of "ITEMS" persist afther closing/reload the world soo is not an overwrite thing

this are the methods i use read write the "ITEMS" in the item stack
