[遊戲] "暗棋王"的翻棋策略

Android 版本
iOS 版本

暗棋是一個深受台灣人喜愛的象棋遊戲，
除了實力外，運氣的好壞也會影響到輸贏，
暗棋的手遊不少，最受人攻擊的點就是有沒有作弊之類的，
以下就"暗棋王"APP開發過程中所考量的翻棋策略做小小的探討，
當然，也期待更多的高手先進多多指教，
讓"暗棋王"的程式演算法更加進步。

以下範例以電腦是紅棋，對手(玩家)是黑棋來講解...
1. "兵"旁邊翻棋
"兵"是所有棋子最弱的，幾乎所有棋子可以吃它，所以在它旁邊翻棋其實是很危險的，有極有的機會害它被對方吃掉，
然而，它也是最強的，因為只有它可以吃"將"，
有些玩家會在"兵"旁邊直接翻棋，如果剛好翻到對方的"將"，那就賺到了，如果沒翻到，大不了損失一隻"兵"，影響不大，不過，已經死了幾隻"兵"，這種策略就不適合，萬一"兵"全死光了，對方的"將"可能就會無敵

2. "帥"旁邊翻棋
 "帥 "是棋子裡最強的，所以在它旁邊翻棋，有機會可以一路吃下去，
然而，常常事與願違，偏偏旁邊翻出的是一隻 "卒 "，這也是暗棋王常常被說作弊的主因， "帥 "旁邊是 "卒 "的機率太高了，
讓我們從數學機率來解釋好了，
如果 "帥 "是位於棋盤4個角，它旁邊會有2顆棋子， "卒 "有5顆，所以 "帥 "旁邊有 "卒 "的機率是2*(5/31)，棋盤有4個角，所以總機率是2*(5/31)*(4/32)，約0.040，也就是4%，
如果 "帥 "是位於棋盤邊上，它旁邊會有3顆棋子， "卒 "有5顆，所以 "帥 "旁邊有 "卒 "的機率是3*(5/31)，棋盤邊上的位置有16個，所以總機率是3*(5/31)*(16/32)，約0.242，也就是24.2%，
如果 "帥 "是位於棋盤中間，它旁邊會有4顆棋子， "卒 "有5顆，所以 "帥 "旁邊有 "卒 "的機率是4*(5/31)，棋盤中間的位置有12個，所以總機率是4*(5/31)*(12/32)，約0.242，也就是24.2%，
將以上所有可能加總0.040+0.242+0.242 = 0.524，也就是52.4%，
換句話說， "帥 "旁邊是 "卒 "是機率約5成左右，機率很高，所以不建議在 "帥 "旁邊直接翻棋，除非 "卒 "已經全死光了^^，
以上的機率是用概估的方式，如有錯誤，歡迎更正

3. "炮"隔子翻棋
"炮"不能直接吃任何隔壁棋子，但如果隔一棋子，它可以吃任何一顆棋，而且距離不限，如下圖：

"炮"可以吃A,B,C三顆棋，紅方可以翻這三顆棋，如果是黑棋，下一輪就可以吃掉它們，
然而，如果翻出的剛好是"包"，"炮"反而會被吃掉，紅方不可一廂情願，
但如果如上圖中"炮"旁邊有一顆"俥"，這時就可以肆無忌憚的翻ＡＢＣ三顆棋，就算翻出"包"，頂多同歸於盡

4. 防止被"包"吃
"包"隔子可吃任何棋，如果己方的棋要被"包"吃了，怎麼處理呢？
如果是如下圖的情形：

紅方可以翻ＡＢＣ任何一顆棋，如果翻出"帥""仕""相""俥""傌"等棋子，就可以間接達到保護紅"仕"的作用，當然，如果黑方認為用"包"去換"仕"是值得的，那黑方還是會照吃。
如果是下圖的情形：

"包"往下走一步就可以吃紅"仕"，紅方可以翻ＤＥＦ三個位置的棋子，如果翻出"帥""仕""相""俥""傌"等棋子，就可以直接達到保護紅仕的作用，當然，紅方還是可以翻ＡＢＣ位置的棋，如上段所提，可以間接保護紅"仕"，選擇翻ＡＣ二處還有一個作用，如果是黑棋，比紅"仕"小的話，紅"仕"吃它就可以逃離"包"的威脅，翻到"將""士"也沒差，反正紅"仕"本來就快可了

5. "包"隔壁翻棋
"包"無法吃任何隔壁棋子，所以我們可以直接在"包"旁邊直接翻棋，反正翻出來的棋一定不會死，反之，如果翻出的棋可以吃掉"包"，那就賺到了，因為"包"的威力很強

6. 保護性翻棋
如下圖左方，"仕"要被"將"吃了：

紅方可選擇翻ＡＢＣ三個位置的棋，如果剛好翻到"兵"，可達到間接保護"仕"的作用，因為"兵"有好幾顆，翻出機率大，有時可以做這樣的賭注，不過，還是有不小的可能會翻出其它紅棋，這樣便會讓"將"有連吃的機會。另外如果紅方"炮"還在，可選擇翻Ｄ處，這種翻法是最安全的，翻到"炮"，可間接保護仕，翻到其它紅棋也不會被"將"吃掉，
如果是如上圖右方，"帥"要被"卒"吃了，紅方一樣可選擇翻ＧＥＦ或Ｈ處的棋，不過，這種情形下間接保護的作用就不大了，因為不管翻到什麼棋，黑方一定會選擇了吃了"帥"再說，死一顆"卒"無所謂

[Corona SDK] How to support multiple Ads networks - AdMob, iAds, Vungle

InHow to add advertisement in my APP - using AdMob V2, we learn how to add AdMob Ads.
For iAds and Vungle, we can use the similar way to add them.
We just consider how to support multiple networks here.
That it, we want to select AdMob, iAds or Vungle dynamically, no matter it is for Fill Rate, eCPM or any other reasons.

Add plugin
First, we need add plug-in in build.settings:

settings =
{
 plugins =
    {
       ["plugin.google.play.services"] =
        {
            publisherId = "com.coronalabs"
        },
        ["CoronaProvider.ads.iads"] =
        {
            publisherId = "com.coronalabs",
            supportedPlatforms = { iphone=true, ["iphone-sim"]=true },
        },
        ["CoronaProvider.ads.vungle"] =
        {
            publisherId = "com.vungle",
        },      
    },
 android =
    {

        usesPermissions =
        {
            "android.permission.INTERNET",
            "android.permission.ACCESS_NETWORK_STATE",
        },
    },
}

Init the Ads

local adsProvider = {"adMob1","adMob2","vungle","iAds"} 
local ads = require( "ads" )
local adMobAdProvider = "admob"
local iAdsAdProvider = "iads"
local vungleAdProvider = "vungle"
local vungleAppId = "55e4xxxxxx"
local bannerAppID = "ca-app-pub-xxxxxx"
local interstitialAppID = "ca-app-pub-xxxxxx"
local appID = "com.gmail.MyCompany.App"
if ( isAndroid ) then
    bannerAppID = "ca-app-pub-xxxxx"
    interstitialAppID = "ca-app-xxxxxx"
    vungleAppId = "com.gmail.My_Company.App"
end
local lastAdsTypeShown = "none"
local currentAds = 1

local function adMobListener( event )
    local msg = event.response
    -- Quick debug message regarding the response from the library
    print( "Message from the adMob library: ", msg )
 if (event.type == "banner") then
     if ( event.isError ) then
         changeToNextAds()
     else
     end
 elseif(event.type == "interstitial") then
        if ( event.isError ) then
            changeToNextAds()
        elseif ( event.phase == "loaded" ) then
        elseif ( event.phase == "shown" ) then
        end
 end  
end

local function iAdsListener( event )
 local msg = event.response
 print("Message received from the iAds library: ", msg)
 if event.isError then
  changeToNextAds() 
 else
 end  
end

local function vungleListener( event )
   print("Message received from the vungleListener library: ", event.type)

   if ( event.type == "adStart" and event.isError ) then
     changeToNextAds()
   elseif ( event.type == "adEnd" ) then
      -- Ad was successfully shown and ended; hide the overlay so the app can resume.
   else
      print( "Received event", event.type )
   end
   return true
end

function adsInit()
 ads.init( adMobAdProvider, bannerAppID, adMobListener )
 if(isAndroid == false) then
   ads.init( iAdsAdProvider, appID, iAdsListener )    
 end
 ads.init( vungleAdProvider, vungleAppId, vungleListener )
end

We have to call ads.init() for AdMob,iAds and Vungle separately.
The parameters in their callback functions are different.
In above codes, we change to next Ads network when we get error.

Change Ads Network
We set new Ads network by function ads:setCurrentProvider().

local function changeToNextAds()
 currentAds = currentAds + 1
 if(currentAds > 3) then
  currentAds = 1
 end
 if(adsProvider[currentAds] == "iAds") then
  ads:setCurrentProvider(iAdsAdProvider)
 elseif(adsProvider[currentAds] == "vungle") then
  ads:setCurrentProvider(vungleAdProvider)
 else
  ads:setCurrentProvider(adMobAdProvider)
 end
end

Show Ads

function showAds(type,px,py)
 if(adsProvider[currentAds] == "adMob") then
  if(type == "banner") then
   ads.show( type, { x=px, y=py, appId=bannerAppID} )
   return true
  elseif(type == "interstitial") then    
   if(ads.isLoaded(type))then
    ads.show( type, { x=px, y=py, appId=interstitialAppID } )
    return true
   else
    return false
   end 
  end 
 elseif(adsProvider[currentAds] == "vungle") then
  if (type == "interstitial" and ads.isAdAvailable() ) then
      ads.show( "interstitial" )
      return true
  else
   return false
  end   
 elseif(adsProvider[currentAds] == "iAds") then
  ads.show( type, { x=px, y=py} )
  return true
 end
 return false  
end

function loadAds()
 if(adsProvider[currentAds] == "adMob") then
  ads.load( "interstitial", { appId=interstitialAppID} )
 end
end 

Vungle does not have Banner Ads and it will pre-load interstitial Ads itself.
iAds cannot pre-load interstitial Ads，
The codes shown above are very completed. 
You can just copy them directly and make it work.

[Corona SDK] 如何支援多個廣告系統 - AdMob, iAds, Vungle

在如何加入廣告 - AdMob V2裡，
我們知道要如何加入AdMob Ads，
要加入iAds和Vungle的話，作法很類似，
在這裡我們討論如果要同時支援的話該如何處理，
也就是說，我們可以動態選擇 AdMob, iAds, Vungle,
不管是因為Fill Rate, eCPM或者其它原因...

Add plugin
首先，我們需要在build.settings加入plug-in:

settings =
{
 plugins =
    {
       ["plugin.google.play.services"] =
        {
            publisherId = "com.coronalabs"
        },
        ["CoronaProvider.ads.iads"] =
        {
            publisherId = "com.coronalabs",
            supportedPlatforms = { iphone=true, ["iphone-sim"]=true },
        },
        ["CoronaProvider.ads.vungle"] =
        {
            publisherId = "com.vungle",
        },      
    },
 android =
    {

        usesPermissions =
        {
            "android.permission.INTERNET",
            "android.permission.ACCESS_NETWORK_STATE",
        },
    },
}

另外，Android需要增加網路存取的權限

Init the Ads

local adsProvider = {"adMob1","adMob2","vungle","iAds"} 
local ads = require( "ads" )
local adMobAdProvider = "admob"
local iAdsAdProvider = "iads"
local vungleAdProvider = "vungle"
local vungleAppId = "55e4xxxxxx"
local bannerAppID = "ca-app-pub-xxxxxx"
local interstitialAppID = "ca-app-pub-xxxxxx"
local appID = "com.gmail.MyCompany.App"
if ( isAndroid ) then
    bannerAppID = "ca-app-pub-xxxxx"
    interstitialAppID = "ca-app-xxxxxx"
    vungleAppId = "com.gmail.My_Company.App"
end
local lastAdsTypeShown = "none"
local currentAds = 1

local function adMobListener( event )
    local msg = event.response
    -- Quick debug message regarding the response from the library
    print( "Message from the adMob library: ", msg )
 if (event.type == "banner") then
     if ( event.isError ) then
         changeToNextAds()
     else
     end
 elseif(event.type == "interstitial") then
        if ( event.isError ) then
            changeToNextAds()
        elseif ( event.phase == "loaded" ) then
        elseif ( event.phase == "shown" ) then
        end
 end  
end

local function iAdsListener( event )
 local msg = event.response
 print("Message received from the iAds library: ", msg)
 if event.isError then
  changeToNextAds() 
 else
 end  
end

local function vungleListener( event )
   print("Message received from the vungleListener library: ", event.type)

   if ( event.type == "adStart" and event.isError ) then
     changeToNextAds()
   elseif ( event.type == "adEnd" ) then
      -- Ad was successfully shown and ended; hide the overlay so the app can resume.
   else
      print( "Received event", event.type )
   end
   return true
end

function adsInit()
 ads.init( adMobAdProvider, bannerAppID, adMobListener )
 if(isAndroid == false) then
   ads.init( iAdsAdProvider, appID, iAdsListener )    
 end
 ads.init( vungleAdProvider, vungleAppId, vungleListener )
end

我們需要針對AdMob,iAds和Vungle各自呼叫ads.init()，
因為callback回傳的參數不同，所以各自傳入不同callback function，
上面的程式裡，我們在callback function裡發現有錯誤時就換下一個Ads，
至於changeToNextAds()是什麼，看下一段

Change Ads Network

local function changeToNextAds()
 currentAds = currentAds + 1
 if(currentAds > 3) then
  currentAds = 1
 end
 if(adsProvider[currentAds] == "iAds") then
  ads:setCurrentProvider(iAdsAdProvider)
 elseif(adsProvider[currentAds] == "vungle") then
  ads:setCurrentProvider(vungleAdProvider)
 else
  ads:setCurrentProvider(adMobAdProvider)
 end
end

我們透過呼叫ads:setCurrentProvider()來設定新的Ads Network,

Show Ads

function showAds(type,px,py)
 if(adsProvider[currentAds] == "adMob") then
  if(type == "banner") then
   ads.show( type, { x=px, y=py, appId=bannerAppID} )
   return true
  elseif(type == "interstitial") then    
   if(ads.isLoaded(type))then
    ads.show( type, { x=px, y=py, appId=interstitialAppID } )
    return true
   else
    return false
   end 
  end 
 elseif(adsProvider[currentAds] == "vungle") then
  if (type == "interstitial" and ads.isAdAvailable() ) then
      ads.show( "interstitial" )
      return true
  else
   return false
  end   
 elseif(adsProvider[currentAds] == "iAds") then
  ads.show( type, { x=px, y=py} )
  return true
 end
 return false  
end

function loadAds()
 if(adsProvider[currentAds] == "adMob") then
  ads.load( "interstitial", { appId=interstitialAppID} )
 end
end 

Vungle沒有Banner Ads, 它自己會pre-load interstitial Ads,
iAds無法pre-load interstitial Ads，
上面的說明應該很完整，
基本上只要照抄就可以了

[Corona SDK] How to add Apple Game Center and Android Google Play Game Service

For Apple Game Center or Android Google Play Game Service, 
we just need to utilize the function of gameNetwork.
It is not difficulty to implement them.
To consider Apple and Google at the same time, 
let's check the codes first and see how them work:

local gameNetwork = require( "gameNetwork" )

  print("event.data is nil")
  return
 end
 for i=1,25 do
  if(event.data[i] == nil) then
   break
  end
  print("event.data[",i,"].playerID:",event.data[i].playerID)
  print("event.data[",i,"].category:",event.data[i].category)
  if(event.data[i].playerID == playerId) then
   print("matched playID...........")
   break
  end
 end
end

  return
 end

 end
 myGameSettings.gameCerterHasEverLoggedIn = true

 end
end
}

Init
In general, we can call gameNetworkSetup() in main.lua，
For Android, we need to check if we have logged in successfully in gpgsInitCallback().
For iOS, we need to check if we have logged in successfully in gameNetworkLoginCallback().
The code gameNetwork.request( "loadLocalPlayer", { listener=loadLocalPlayerCallback } ) is to confirm the user who logs in.
You can go without it.
The code gameNetwork.request( "loadAchievements", { listener=loadAchievementCallback } ) is to recover the users's records.
For example, users may have ever installed this APP, remove this APP, and re-install it again.
If you think that you don't need to recover the records for them, you can go with it.

Show leaderboard
To show the leaderboard, we just need to call function showLeaderboards().
In general, we do it when user press some button

Show achievement
To show the leaderboard, we just need to call function showAchievements().
In general, we do it when user press some button.

Update leaderboard
To update leaderboard, we just need to call function updateLeaderBoards().
In general, wwe do it when user finish the game.

Update achievements 
To update leaderboard, we just need to call function updateAchievement().
In general, wwe do it when user finish some round.


Below are what differ between Apple Game Center and Android Google Play Game Service:

Apple Game Center

The data in leaderboardsListId{} and achievementsListId{}:
e.g. "com.gmail.mycom.demo.Leaderboards.HighestScore".
They are user defined, as long as they are  not duplicated.

Google Play Game Service

The data in leaderboardsListId{} and achievementsListId{}:
e.g. "Cgkxxxxxxxx".
They are defined by play store publish when you finished the setting in game center.
For Google Play Game Service， we also need to add the googlePlayGamesAppId in build.settings:

android =
    {
        usesPermissions =
        {
            "android.permission.INTERNET",
            "android.permission.ACCESS_NETWORK_STATE",
            "com.android.vending.BILLING",
        },
        googlePlayGamesAppId = "123456789012" 
    },

usesPermissions are not concerned for game service，
googlePlayGamesAppId is what you get when you link the APP in play store publish game center.

[Corona SDK] 如何加入Apple Game Center 和 Android Google Play Game Service

不管是Apple的Game Center，還是Android的Google Play Game Service，
基本上都是利用gameNetwork的功能即可，
實作不難，考慮同時支援Apple和Google，
先將程式碼貼上再來講解：

local gameNetwork = require( "gameNetwork" )
local playerName
local playerId

local leaderboardsListId=
{
 ["HighestScore"]=
 {
  ["Description"] = "Highest Score",
  ["Identifier"] = "com.gmail.mycom.demo.Leaderboards.HighestScore"
 }
}

local achievementsListId = 
{
 ["FinishLevel1"]=
 {
  ["Description"] = "Finish Level 1",
  ["Identifier"] = "com.gmail.mycom.demo.Achievements.FinishLevel1"
 },
 ["FinishLevel2"]=
 {
  ["Description"] = "Finish Level 2",
  ["Identifier"] = "com.gmail.mycom.demo.Achievements.FinishLevel2"
 }
}

if(isAndroid) then
 leaderboardsListId=
 {
  ["HighestScore"]=
  {
   ["Description"] = "Highest Score",
   ["Identifier"] = "Cgkxxxxxxxx"
  }
 }

 achievementsListId = 
 {
  ["FinishLevel1"]=
  {
   ["Description"] = "Finish Level 1",
   ["Identifier"] = "Cgkxxxxxxx"
  },
  ["FinishLevel2"]=
  {
   ["Description"] = "Finish Level 2",
   ["Identifier"] = "Cgkxxxxxxxx"
  }
 }
end



function showLeaderboards( event )
 print("showLeaderboards()")
 if (playerId ~= nil) then
    if ( isAndroid ) then
       gameNetwork.show( "leaderboards" )
    else
       gameNetwork.show( "leaderboards", { leaderboard = {timeScope="AllTime"} } )
    end
 else
  gameNetworkSetup()
 end
    return true
end

local function postScoreSubmit( event )
   --whatever code you need following a score submission...
   return true
end

local function updateLeaderBoards(type, myScore)
 if (playerId == nil) then
  return
 end

 gameNetwork.request( "setHighScore",
 {
    localPlayerScore = { category=leaderboardsListId[type]["Identifier"], value=tonumber(myScore) },
    listener = postScoreSubmit
 } )
 print("gameNetwork.request( setHighScore) finished")
end

function showAchievements( event )
 print("showAchievements()")
 if (playerId ~= nil) then
    gameNetwork.show( "achievements" )
 else
  gameNetworkSetup()
 end
    return
end

local function achievementRequestCallback( event )
   
   return true
end

local function updateAchievement(type)
 if (playerId == nil) then
  return
 end
 gameNetwork.request( "unlockAchievement",
 {
    achievement = { identifier=achievementsListId[type]["Identifier"], percentComplete=100, showsCompletionBanner=true },
    listener = achievementRequestCallback
 } )
end

local function loadScoresCallback( event ) 
 if(event.data == nil) then
  print("event.data is nil")
  return
 end
 for i=1,25 do
  if(event.data[i] == nil) then
   break
  end
  print("event.data[",i,"].playerID:",event.data[i].playerID)
  print("event.data[",i,"].category:",event.data[i].category)
  if(event.data[i].playerID == playerId) then
   print("matched playID...........")
   break
  end
 end
end

local function loadLocalPlayerCallback( event ) 
 if(event.data == nil) then
  print("event.data is nil")
  return
 end

 playerId = event.data.playerID
 playerName = event.data.alias
 print("loadLocalPlayerCallback(),playerName:",playerName,",playerId:",playerId)
 if(playerId == nil) then
  return
 end
 myGameSettings.gameCerterHasEverLoggedIn = true
 saveData()   

 gameNetwork.request( "loadScores",
            {
                leaderboard =
                {
                    category = leaderboardsListId["HighestScore"]["Identifier"], 
                    playerScope = "Global",   -- Global, FriendsOnly
                    timeScope = "AllTime",    -- AllTime, Week, Today
                    --range = {1,5},
                    playerCentered = true,
                },
                listener = loadScoresCallback
            }) 
end

local function loadAchievementCallback( event )    
 if(event.data == nil) then
  print("event.data is nil")
  return
 end

 for i=1,#event.data do
  if(event.data[i] ~= nil) then
   print("event.data[",i,"].identifier:",event.data[i].identifier)
   print("event.data[",i,"].title:",event.data[i].title)
   print("event.data[",i,"].isCompleted:",event.data[i].isCompleted)
  end
 end 
end

local function gameNetworkLoginCallback( event )
 if(isAndroid==false) then
  if(event.data) then
   print("User has logged into iOS Game Center")
  else
   print("User has NOT logged into iOS Game Center")
   return 
  end
 end
 gameNetwork.request( "loadLocalPlayer", { listener=loadLocalPlayerCallback } )
 gameNetwork.request( "loadAchievements", { listener=loadAchievementCallback } )
 return true
end

local function gpgsInitCallback( event )
 if(event.data) then
  print("User has logged into Google App Play Center")
     gameNetwork.request( "login", { userInitiated=true, listener=gameNetworkLoginCallback } )
 else
  print("User has NOT logged into Google App Play Center")
 end
end

function gameNetworkSetup()
 if ( isAndroid ) then
  myGameSettings.gameCerterHasEverLoggedIn = false
  gameNetwork.init( "google", gpgsInitCallback )
 else
  gameNetwork.init( "gamecenter", gameNetworkLoginCallback )
 end
end
}

初始化
一般來說，我們可以在main.lua裡呼叫gameNetworkSetup()，
對於Android系統，在gpgsInitCallback()裡可以確認是否登錄成功
對於iOS系統，在gameNetworkLoginCallback()裡可以確認是否登錄成功，
至於後面的gameNetwork.request( "loadLocalPlayer", { listener=loadLocalPlayerCallback } )，
是用來確認目前登錄遊戲中心的使用者，有沒有呼叫它都可以，
gameNetwork.request( "loadAchievements", { listener=loadAchievementCallback } )則是用來回復使用者的紀錄， 例如使用曾經安裝過這個APP，移除它後又重新下載， 如果不想幫使用者回復紀錄，不執行也可以

顯示排行榜(leaderboard)
想要顯示排行榜，只要呼叫showLeaderboards()即可， 通常這個動作是在使用者按下某個按鈕時

顯示任務(achievement)
想要顯示排行榜，只要呼叫showAchievements()即可， 通常這個動作是在使用者按下某個按鈕時

更新排行榜 想要更新排行榜，只要呼叫updateLeaderBoards()即可， 通常這個動作是在使用者完成遊戲時

更新任務 想要更新排行榜，只要呼叫updateAchievement()即可， 通常這個動作是在使用者完成某個關卡時


以下是Apple的Game Center，和Android的Google Play Game Service稍有不同的地方

Apple Game Center

leaderboardsListId{}和achievementsListId{}裡的資料， 例如"com.gmail.mycom.demo.Leaderboards.HighestScore"， 這是使用者自己決定的編碼，然後在iTunes Connect裡設定即可， 不重覆就行

Google Play Game Service

leaderboardsListId{}和achievementsListId{}裡的資料，
例如"Cgkxxxxxxxx"， 這是使用者在play store publish的遊戲中心設定後系統給的編碼， 另外，對於Google Play Game Service， 我們還需要在build.settings增加:

android =
    {
        usesPermissions =
        {
            "android.permission.INTERNET",
            "android.permission.ACCESS_NETWORK_STATE",
            "com.android.vending.BILLING",
        },
        googlePlayGamesAppId = "123456789012" 
    },

usesPermissions無所謂，
googlePlayGamesAppId是在play store publish的遊戲中心連結應用程式後系統給的編碼
