我对来自 Maya 2013 API的示例命令插件有疑问 为了清楚起见,插件的代码已拆分为 .h 和 .cpp 文件,但在其他方面应该是正确的。
插件Cmd.h:
// Include the needed headers.
#include <stdio.h>
#include <maya/MString.h>
#include <maya/MArgList.h>
#include <maya/MFnPlugin.h>
#include <maya/MPxCommand.h>
#include <maya/MIOStream.h>
// Class to represent our command.
class commandExample : public MPxCommand
{
public:
commandExample();
virtual ~commandExample();
MStatus doIt( const MArgList& );
MStatus redoIt();
MStatus undoIt();
bool isUndoable() const;
static void* creator();
};
pluginCmd.cpp:
// Include the header for the file.
#include "pluginCmd.h"
// Constructor for the command object.
commandExample::commandExample() {
cout << "In commandExample::commandExample()\n";
}
// Destructor for the command object.
commandExample::~commandExample() {
cout << "In commandExample::~commandExample()\n";
}
// The actual command/work to be performed.
MStatus commandExample::doIt( const MArgList& ) {
cout << "In commandExample::doIt()\n";
return MS::kSuccess;
}
// The creator is called when the command is invoked and sets up the command object.
void* commandExample::creator() {
cout << "In commandExample::creator()\n";
return new commandExample();
}
// Gets called when the plugin is loaded into Maya.
MStatus initializePlugin( MObject obj ) {
// Set plugin registration info: Author, plugin-version and Maya version needed.
MFnPlugin plugin( obj, "Martin Jørgensen", "1.0", "Any" );
plugin.registerCommand( "commandExample", commandExample::creator );
// Print to show plugin command was registered.
cout << "In initializePlugin()\n";
return MS::kSuccess;
}
// Gets called when the plugin is unloaded from Maya.
MStatus uninitializePlugin( MObject obj )
{
MFnPlugin plugin( obj );
plugin.deregisterCommand( "commandExample" );
// Print to show the plugin was unloaded.
cout << "In uninitializePlugin()\n";
return MS::kSuccess;
}
它在带有 Maya 2013 x64 库的 Windows 7 x64 Visual Studio 12 上成功编译。当它在插件管理器中加载时,会发生注意(它应该打印初始化状态)。但是当它被卸载时,会出现初始化打印。有谁知道这是为什么?
