Maya+VS編程入門初體驗(HelloWorld)

Maya2018 + VS2017 環境搭建見 博客

1. 項目：

VS 新建了一個 MEL Command類型的項目(MayaProject)

2. HelloWorld代碼

#include<maya/MSimple.h>

// Use helper macro to register a command with Maya.  It creates and
// registers a command that does not support undo or redo.  The 
// created class derives off of MPxCommand.
//
DeclareSimpleCommand( MayaProject, "", "2018");

MStatus sayHello::doIt(const MArgList& args )
{

    MStatus stat = MS::kSuccess;

    displayInfo("Hello World!");

    // Since this class is derived off of MPxCommand, you can use the

    // inherited methods to return values and set error messages

    //

    setResult( "sayHello command executed!/n" );

    return stat;

}

3.  運行，debug文件夾中出現了一個mll文件

4. 把mll文件拷貝到C:\MyProgram\AutoDesk\Maya2018\bin\plug-ins目錄下，而後從新打開maya

菜單->窗口->設置/首選項->插件管理器

MayaProject插件加載進來

5. 在maya底部的MEL腳本編輯器中輸入腳本，對插件進行測試

6. 腳本編輯器顯示 結果

//        MS::kSuccess - command succeeded
//        MS::kFailure - command failed (returning this value will cause the 
//                     MEL script that is being run to terminate unless the
//                     error is caught using a "catch" statement.
