要在minecraft中新增合成表，要先到data資料夾新增rubymod/recipes，之後在recipes資料夾內放上2個json檔案，名字可以任意取(建議取直觀一點)。
首先是ruby_block_to_ruby.json這是把紅寶石方塊拆解成9個紅寶石{ "type": "minecraft:crafting_shapeless", "category": "misc", "ingredients": [ { "item": "rubymod:ruby_block" } ], "result": { "item": "rubymod:ruby", "count": 9 } }

再來是ruby_to_ruby_block.json，這是把9個紅寶石合成紅寶石方塊{ "type": "minecraft:crafting_shaped", "category": "misc", "pattern": [ "###", "###", "###" ], "key": { "#": { "item": "rubymod:ruby" } }, "result": { "item": "rubymod:ruby_block" } }
