祭坛合成

本章涉及内容：自定义结构、配方检测、配方注册、JEI自定义注册、物品实体涉及模组及版本:

祭坛使用配方和注册配方

祭坛破坏掉落里面的物品

注:该代码应在server_scripts里

JEIAddedEvents.registerRecipes((event) => {
    let cb = event.custom("meng:block_test")
    for (const key of global.testRecipe) {
        cb.add({ output: key.outputItem, inputs: key.inputItems, principal: key.principalItem })
    }
});

JEIAddedEvents.registerRecipeCatalysts(jei =>{
    jei.data.addRecipeCatalyst("meng:test_block","meng:block_test")

一些注意事项

该项目的配方检测全是字符串，并不是ItemStack所以无法检测nbt，如需请自行更改
该项目只是作为示例，很多地方并不是最优解，可自行进行解决
如果对该项目代码部分不满可以将修改好的代码上传至gitee项目仓库
项目完整代码在这里
因为物品渲染使用的物品掉落物实体，所以会被kill @e[type="item"] 给清理掉，所以得注意一下(可以考虑写一个方块tick事件去检测解决)
