require "uiDefine"

報錯資訊：module 'uiDefine' not found:

no fieldpackage.preload['uiDefine']

no such builtin lib'uiDefine'

解決方法： 在require "ui.uiDefine" 在基於lua根目錄的下require全路徑，例如Assets/Scripts/lua為根目錄

static public class UnityCommonExtension

{

static public void DestroyAllChildren(this GameObject target)

           {

       foreach (Transform child in target.transform)

       {

            GameObject.Destroy(child.gameObject);

       }

    }

}

for i = 1, #headIconParent do

                   headIconParent[i]:DestroyAllChildren()

End

         如果

public static class LuaGenConfig

{

   //lua中要使用到C#庫的配置，比如C#標準庫，或者UnityAPI，第三方庫等。

   [LuaCallCSharp

   public static List<Type> LuaCallCSharp = new List<Type>()

{

//typeof(UnityCommonExtension),

}

}

報錯資訊: attemptto call a nil value (method 'DestroyAllChildren')

解決方法：

for i = 1, #headIconParent do

                   CS.UnityCommonExtension.DestroyAllChildren(headIconParent[i])

End

或者 LuaGenConfig新增上，然後用 

或 headIconParent[i].DestroyAllChildren(headIconParent[i])即可

for i = 1, pairs(headIconParent) do end

報錯資訊：'for'limit must be a number

解決方法：用 for i= 1, #headIconParent do end

而for k, v pairs(headIconParent) do end 也可以

C# 的陣列傳到lua裡，

local widgets = {}--go:GetComponentsInChildren("UIWidget",true)    

           local widArr =InterfaceForLua.GetWidgetArray(go)

           for i = 0, widArr.Length - 1 do

             table.insert(widgets, widArr[i])

           end

但是c#的list傳到lua裡就不能被識別。

如果定義的是方法，要寫function()#### end, 否則不寫會執行呼叫的函式，而不是傳進去的方法。

定義的 lua方法，：定義：呼叫，.定義.呼叫 , :也用在c#靜態方法的呼叫，省去self

function UIItemIconInfo:CreateItemIcon(itemNum, parent, uniqueName)

         local go =ResUtil.LoadGameObject("UI/CommonIcon/ItemIconInfoLua")

    local script = {}

         setmetatable(script,{__index = UIItemIconInfo}

script.gameObject = go

    script.Data = itemNum

         script.eName =uniqueName

         script:InitEvent()

    script:awake()

    script:onBindComplete()

script:start()

    if parent ~= nil then

     parent:AddChildEx(go.transform)

    end

    go.name =string.format("Item%s", tostring(itemNum.ItemId))

    if parent ~= nil andparent:GetComponent("UIWidget") ~= nil then

      local parentDepth =parent:GetComponent("UIWidget").depth

      local widgets = {}   localwidArr = InterfaceForLua.GetWidgetArray(go)

           for i = 0, widArr.Length - 1 do

             table.insert(widgets, widArr[i])

           end

           for k in pairs(widgets) do

                   widgets[k].depth= widgets[k].depth + parentDepth

           end

    end

         return script

end

function UIItemIconInfo:onBindComplete()

  self:SetMask(false)

  self:ItemIconCanClick(true)

 self:AddDragScrollView(false, nil)

 self:SetItemIconScale(Vector3.one)

 self:SetBackGroundVisable(true, true)

         self:SetSelectHide(true)

end

function UIItemIconInfo:SetMask(bVis)

  Mask:SetActive(bVis)

End

self 與單例的使用

這些就是lua單例的使用方法

local widgets = {}

local widArr = InterfaceForLua.GetWidgetArray(go) –這個是c#傳過來的UIWidget[]

logError(typeof(widgets).."  "..typeof(widArr))  --  table  userdata

--widgets = widArr  --如果能成功，表相等，是引用，一個改另一個跟著改

         table.insert(widgets,widArr) --如果能成功，表insert，是獨立的表

報錯資訊：attemptto get length of a userdata value

解決方法：遍歷userdata,進行插入表

for i = 0, widArr.Length - 1 do

         table.insert(widgets,widArr[i])

end

---------for迴圈

for i = 1, #widgets do

widgets[i].depth = widgets[i].depth + parentDepth

end

for k in pairs(widgets) do

print(k)

         widgets[k].depth = widgets[k].depth +parentDepth

end

-------這兩個一樣的作用

local widArr = InterfaceForLua.GetWidgetArray(go)  加入local 變數  widArr.Length獲取長度 5.2之前table.getn

LuaException: ui.CommonIcon.UIItemIconInfoLua:157: attempt toperform arithmetic on a nil value (field 'depth')

stack traceback:

         ui.CommonIcon.UIItemIconInfoLua:157:in field 'CreateItemIcon'

解決方法：

stack traceback:

解決方法：'SetActive'不是static方法，要用：訪問

UIItemIconInfo script = go:GetComponent('UIItemIconInfo')

報錯資訊：syntax error near 'script'

解決方法：宣告為local即可

go.transform.localScale =CS.UnityEngine.Vector3(0.7f, 0.7f, 0.7f) （lua中沒有new）

報錯資訊：malformed number near '0.7f'

解決方法：把f去掉，lua沒有integer和float型別之分，數值都是用number型別表示的，

attempt to perform arithmetic on a stringvalue

stack traceback:

解決方案：這個寫成的c#的語法了，把+ 變成.. 例如print("AAAAAAAAbbb: " + tostring(Data.Reward.Count))

解決方法：29行呼叫到地方檢查，就到了require 的地方，比如檢查 = 號賦值
