Metal Barrels
Storage upgrade to vanilla barrels
About this Mod
This mod adds additional barrels to the game that can store more items.
They function like their vanilla counterparts in that they can be opened with a solid block on top and don't cause any fps issues in large numbers unlike chests.
Copper stores 45 stacks
Iron stores 54 stacks
Silver stores 72 stacks
Gold stores 81 stacks
Diamond stores 108 stacks
Crystal stored 108 stacks and is transparent
Obsidian stores 108 stacks but has a blast resistance equivalent to obsidian making it resistant to most explosions
Netherite stores 135 stacks and has the fire resistance + blast resistance of netherite
There are now upgrade items that can be used to upgrade already placed barrels without breaking them, the contents will not be destroyed or dropped if used.
