L4D2 惡靈勢力2 同PC分割畫面雙人玩！任何搖桿都可以！

前一陣子想要在同一台電腦上兩個人用分割畫面一起玩L4D2，結果搞了好久都沒搞定，昨天晚上研究到半夜兩點終於把他搞定了！可喜可賀，可喜可賀～那到底要怎麼做勒？

首先要先下載一個軟體，把搖桿模擬成player 2，這樣第二個人加進來之後才有得控制

下載完解壓縮。

打開xbox360cemu.ini，把[PAD1]改成[PAD2]，[PAD2]改成[PAD1]，接下來都要修改[PAD2]下面的參數。不過因為每個搖桿對應的參數都不一樣，所以請自行修改成正確的對應值。修改完存檔，執行XInputTest.exe來看對應的關係，如果要再修改，還是一樣存檔完，XInputTest.exe重新再開一次才會更新。



Left Analog X=1        //左類比X軸
Left Analog Y=-2       //左類比Y軸
Right Analog X=3       //右類比X軸
Right Analog Y=-6      //右類比Y軸
A=2                    //A
B=3                    //B
X=1                    //X
Y=4                    //Y
Left Shoulder=5        //LB
Right Shoulder=6       //RB
Back=9                 //BACK
Start=10               //START
Left Thumb=11          //左類比壓下去(哈哈不會講)
Right Thumb=12         //右類比壓下去
Left Trigger=7         //LT
Right Trigger=8        //RT



改這些就好了，大致上自己慢慢橋，應該都還可以橋的出來。

如果用的是原版的xbox360 controller for windows就要使用另外一個檔案來有辦法完全對應成功：

下載完一樣解壓縮編輯存檔即可。

調整完畢後，把解壓縮出來的檔案全部放到主程式left4dead2.exe所在位置～另外還要做的一件事情是要把bin資料夾裡面的xinput1_3.dll改名～這邊就完成了～

接下來只差一件事情：建立一個.txt檔，裡面要放的內容如下：

ss_splitmode 2;
connect_splitscreen localhost 2;

name2 xcrossd    //這邊可以把Player2改名

/*到上面那一行*/


檔案自己隨便想叫什麼名字都可以(最好是英文命名)，我命名為Splitmode.txt，存放的位置在left4dead2\cfg資料夾裡面。

接著就開始遊戲，打開console(壓 "~"，如果沒反應，到Options>>Keyboard and Mouse>>Enable Developer Console，不好意思不知道中文是什麼)

裡面打 "ss_map c?m?_xxxxxx" ，後面的是可以自己選要打哪個地圖，他會有下拉式選單輔助

進入遊戲後，再次打開console，這次打 "exec Splitmode.txt" ，後面的檔名可以根據自己的命名來調整

大功告成！！


如果想要回覆原來的樣子，可以用搖桿玩Player1的話，要把放到主程式的那些檔案全部刪掉，然後再把\bin裡面改名過後的xinput1_3.dll 改成原來的名字。總之，就是把一切都還原。
