1.12.2版本的文件位于.minecraftconfigmmorpgCompatibleItems.txt，打开后在里面新增下面的内容.
强烈建议使用notepad++打开，不然会出现未知错误
首先是预留格式：
{
"version": "1.0",
"map": {
"modid:itemid1": {
"itemType": "Sword",
"isSalvagable": true,
"dropWeight": 1000,
"uniqueItemWeight": 0,
"normalItemWeight": 80,
"runedItemWeight": 20,
"randomUniqueUpToTier": 10,
"minRarity": 0,
"maxRarity": 5,
"levelVariance": 0,
"uniqueId": "",
"uniqueIsRandom": true,
"minLevel": 1,
"maxLevel": 100,
"statsAddedOnlyOnDrop": false,
"dropsAsLoot": true
},
"modid:itemid2": {
"itemType": "Sword",
"isSalvagable": true,
"dropWeight": 1000,
"uniqueItemWeight": 0,
"normalItemWeight": 80,
"runedItemWeight": 20,
"randomUniqueUpToTier": 10,
"minRarity": 0,
"maxRarity": 5,
"levelVariance": 0,
"uniqueId": "",
"uniqueIsRandom": true,
"minLevel": 1,
"maxLevel": 100,
"statsAddedOnlyOnDrop": false,
"dropsAsLoot": true
}
},
"list": []
}
然后在预留格式下面开始添加：
"ID（这个按F3+H可以查看）": {
"itemType": "类型，剑是Sword，法杖是Staff，弓是Bow，锤子是Hammer，斧子是Axe，盾牌是Shield，头盔是Helmet，胸甲是Chest，护腿是Pants，靴子是Boots",
"isSalvagable": true,
"dropWeight": 1000,
"uniqueItemWeight": 0,
"normalItemWeight": 80,
"runedItemWeight": 20,
"randomUniqueUpToTier": 10,
"minRarity": 最小品阶,
"maxRarity": 最大品阶,
（注意：品级范围最小是0最大是5，对应黑铁级-钻石级）
"levelVariance": 0,
"uniqueId": "",
"uniqueIsRandom": true,
"minLevel": 最小等级,
"maxLevel": 最大等级,
"statsAddedOnlyOnDrop": false,
"dropsAsLoot": true
},
没懂？举个栗子，我想兼容背刺模组的钻石匕首，归类为剑，最低品级(minRarity)为黑铁，最高品级(maxRarity)为钻石，装备时同步玩家等级范围为(minLevel)30-80级(maxLevel)
"backstab:diamond_dagger": {
"itemType": "Sword",
"isSalvagable": true,
"dropWeight": 1000,
"uniqueItemWeight": 0,
"normalItemWeight": 80,
"runedItemWeight": 20,
"randomUniqueUpToTier": 10,
"minRarity": 0,
"maxRarity": 5,
"levelVariance": 0,
"uniqueId": "",
"uniqueIsRandom": true,
"minLevel": 30,
"maxLevel": 80,
"statsAddedOnlyOnDrop": false,
"dropsAsLoot": true
},
内容是添加在这个下面！也就是预留两条的中间！！！
