This Mod allows you to configure block placing limits. So each Player can place these blocks until its limit is reached. Created as part of the "Shattered World" Modpack (Work in Progress / Not released yet) to balance some heavy usage production lines.
Example ( configFile -> Result ):
Block without MetaId ( <mod>:<blockName> )
minecraft:stone=2 => Allows each Player to place max. 2 Stones.
Block with MetaId ( <mod>:<blockName>:<metaId> )
minecraft:log:2=2 => Allows each Player to place max. 2 Birch Wood Logs.
Block ignore MetaId ( <mod>:<blockName>:* )
minecraft:log:*=2 => Allows each Player to place max. 2 Oak, Spruce, Birch or Jungle Wood Logs.
