由於犀牛引擎不支持JavaScript的class對象，所以只能使用function的protoype來建立一個類似於class的function，具體解析如下：

配方Json樣本：

{
  "type": "ae2:inscriber",
  "mode": "inscribe",
  "result": {
    "item": "ae2:printed_calculation_processor"
  },
  "ingredients": {
    "top": {
      "item": "lazierae2:universal_press"
    },
    "middle": {
      "item": "ae2:certus_quartz_crystal"
    }
  }
}

代碼：

//AE2的壓印機
function ae2Inscriber() {
//初始化配方主體
    this.recipe = {
        type: 'ae2:inscriber',
        mode: 'press',
        result: {},
        ingredients: {}
    }
}
//定義方法，注意每個方法除了build和replace方法為最終創建方法外,都需要return本身以方便多次調用方法來設置屬性
ae2Inscriber.prototype = {
    //更改配方模式
    setMode: function (mode) {
        this.recipe.mode = mode;
        return this;
    },
    //更改輸出物品
    setResult: function (result) {
        this.recipe.result = result;
        return this;
    },
    //更改頂部輸入，格式為Ingredient
    setIngredientsTop: function (ingredientsTop) {
        this.recipe.ingredients.top = ingredientsTop;
        return this;
    },
    //更改中間輸入，格式為Ingredient
    setIngredientsMiddle: function (ingredientsMiddle) {
        this.recipe.ingredients.middle = ingredientsMiddle;
        return this;
    },
    //更改底部輸入，格式為Ingredient
    setIngredientsBottom: function (ingredientsBottom) {
        this.recipe.ingredients.bottom = ingredientsBottom;
        return this;
    },
    //如果是shapeless配方怎麼辦？即輸入的Ingredients為一個數組,這裡假設壓印器的ingredients是一個數組
    //addIngredients: function (Ingredients) {
        //this.recipe.ingredients.push(Ingredients);
       // return this;
    //},
    //Over
    //創建配方，需要傳入recipe事件和配方名稱，自動生成配方的ResourceLocation,namespace為預先設置的常量，或者直接改為你需要的字串即可
    //可以取消配方名稱設置但是下面的replace方法也要去掉該變數的傳入
    build: function (event, recipename) {
        event.custom(this.recipe).id(namespace + ':inscriber/' + recipename);
        return;
    },
    //替代配方，先根據配方id刪除配方，然後調用build創建配方
    replaceRecipe: function (event, recipeid) {
        event.remove({ id: recipeid });
        let recipename = recipeid.split(':')[1].split('/').pop();
        this.build(event, recipename);
    }
};

//上面一個壓印器的builder定義就完成了，以下是調用

onEvent('recipes', event => {
    new ae2Inscriber()  //在recipes事件內調用builder
        .setResult(Item.of('ae2:logic_processor').toJson())                   //設置輸出，參數為Ingredient，支持修改數量、NBT等，詳見其他教學,下同
        .setMode('press')                                                     //設置壓印模式為壓印
        .setIngredientsTop(Item.of('ae2:printed_logic_processor').toJson())   //設置頂部輸入為邏輯電路板
        .setIngredientsMiddle(Ingredient.of('#forge:ingots/copper').toJson()) //設置中間輸入為標籤：銅錠
        .setIngredientsBottom(Item.of('ae2:printed_silicon').toJson())        //設置底部輸入為矽板
        .replaceRecipe(event, 'ae2:inscriber/logic_processor');               //調用替代方法，替代原有的配方
});
