教學:製作附加包/交易表
出自Minecraft基岩版开发Wiki
 | 本條目仍需完善。 |
在這之前[編輯]
我們先要看一下村民交易列表的GUI結構（以圖書管理員為例）：
可以分為以下要點：
- Minecraft將交易列表進行分級，只要達到一定等級才可以解鎖更多交易。
- 交易一次可為村民增加交易經驗（交易欄上方的經驗條），積累到一定經驗後可以解鎖下一等級的交易。
- 至少要有一級新手級（流浪商人的交易列表預設隱藏）。
- 每一級中至少有一個或更多的交易。
知道這些遊戲內容後，我們可以繼續下一步的教學。
基本結構[編輯]
交易表的json檔案存放在行為包/trades資料夾中。
新建一個json檔案，放入以下欄位：
{
"tiers":[
]
}
可以看到交易表沒有宣告格式版本和賦命名空間識別碼。
在"tiers"陣列內，每一個JSON物件都代表着一個交易等級，需填入以下欄位：
[
{
"total_exp_required": 0,//交易所需经验
"groups": []
}
]
注意：交易表中一定要有所需經驗為0的交易等級！！！
到了"groups"陣列，就要定義交易內容了，每個交易欄位是一個JSON物件，格式如下（從圖書管理員中截取）：
{
"num_to_select": 1,//从以下交易中随机选一个，放置到交易列表。
"trades": [//交易内容
{
"wants": [//被交易物品
//一个物品定义一个JSON对象
{
"item": "minecraft:paper",//物品的赋命名空间标识符
"quantity": 24,//数量
"price_multiplier": 0.05//价格乘数
}
],
"gives": [//交易后物品
{
"item": "minecraft:emerald",
"quantity": 1
}
],
"trader_exp": 2,//村民交易后获得的经验
"max_uses": 16,//村民单种交易上限
"reward_exp": true//是否给予玩家经验
}
]
}
到這裏，基本上交易表應該可以被Minecraft讀取了，下面是一些特殊的定義。
函式引用[編輯]
在圖書管理員的交易列表中，有一種特殊的交易表，用綠寶石和書交易附魔書，這種交易需用到函式。 函式的基本結構如下：
"functions":[
{
"function": "需要调用的函数"
},
{...}
]
以下是各個函式[需要更多資訊]：
enchant_book_for_trading[編輯]
將書附上附魔。
結構如下[需要驗證]：
"functions": [
{
"function": "enchant_book_for_trading",
"base_cost": 2,//附魔失败时物品最少需要的绿宝石
"base_random_cost": 5,//附魔上1级附魔成功时最少需要的绿宝石
"per_level_random_cost": 10,//附魔书花费的绿宝石上限（此项加下一项的数值）
"per_level_cost": 3//每高一级需要的绿宝石
}
範例[編輯]
如果沒有錯誤，交易表應該為如下形式（以圖書管理員的交易列表為例）：
{
"tiers": [
{
"total_exp_required": 0,
"groups": [
{
"num_to_select": 1,
