最近項目要求通過java給max發送任務指令，max接收指令執行任務，并且返回執行的結果。不管為什么會有這樣的需求，有就要去實現。

1、OLE開啟

Max本身提供了一個方式，它可以將自己注冊成一個Ole自動化對象，默認是沒有開啟的，開啟這個接口只需要操作注冊表即可。將該腳本存放的max的安裝路徑下的Scripts\StartUp，即max啟動時會默認加載的腳本。保證max啟動以后會執行該腳本。

關于腳本中內容具體請參考Maxscript的自帶文檔 OLE Automation 章節。

2、編寫socket通訊dll（C#）

為什么要開啟ole，是因為該dll用到了ole。為什么用C#寫dll通信，是因為我對C#比較熟悉，還有就是maxscript中雖然可以調用donet的方法，但是語法上寫起來很別扭，之前也寫過ms一版，有些問題在ms中不好解決，比如在在調用ms中的執行了“importFile (strIn) #noPrompt” 時會發生未知錯誤。下面會貼上C#和ms兩個版本的socket通訊代碼（都是demo版本，僅供參考）。這里max都是做服務端，需要循環監聽客戶端的消息。

3、使用ms加載dll

下面的腳本要在max啟動的時候執行，建議放在max的安裝目錄下的Scripts\StartUp

1 Fn GetDotNetAssemblyByFile dllFileName = 2 ( 3 local result 4 DotNetAssembly = dotNetClass "System.Reflection.Assembly" 5 6 tempFolder = SysInfo.TempDir 7 sourceFileName = GetFilenameFile dllFileName 8 tempPrefix = (GenClassID returnValue:true)[1] as string 9 tempFileName = tempFolder + tempPrefix + sourceFileName + GetFilenameType dllFileName 10 CopyFile dllFileName tempFileName 11 result = DotNetAssembly.LoadFile tempFileName 12 result 13 ) 14 15 DotNetActivator = DotNetClass "System.Activator" 16 --根據實際路徑填寫 17 TestAssembly = GetDotNetAssemblyByFile @"C:\Program Files\Autodesk\3ds Max 2016\scripts\Startup\SocketBy3DMAX.dll" 18 TestClassType = TestAssembly.GetType("SocketTest.SocketServer") 19 TestClassObject = DotNetActivator.CreateInstance TestClassType 20 TestClassObject.InitSocket() ms加載dll
