ogre1.7 cookbook_OgrePlugin+OgreMfc

建立一个win32 project, application setting时选择dll, empty project.

项目工程属性配置同前。

#pragma once

#include "Ogre.h"
#include "OgrePlugin.h"

class RobotPlugin: public Ogre::Plugin
{
public:
    Ogre::String m_strName;

public:
    RobotPlugin(): m_strName("robot") {}
    const Ogre::String& getName() const {return m_strName;}
    void install() {}
    void initialise()
    {
        Ogre::SceneManager* sceneMgr = Ogre::Root::getSingleton().getSceneManager("ogreMfc");
        Ogre::Entity* robot = sceneMgr->createEntity("robot", "robot.mesh");
        Ogre::SceneNode* robotNode = sceneMgr->getRootSceneNode()->createChildSceneNode("robot");
        robotNode->attachObject(robot);
        robotNode->setPosition(Ogre::Vector3(100, 0 , 0));

        Ogre::AxisAlignedBox box = robot->getBoundingBox();
        Ogre::Vector3 center = box.getCenter();
        Ogre::Camera* camera = sceneMgr->getCamera("ogreMfcCamera");
        camera->lookAt(center);

        Ogre::Root::getSingleton().renderOneFrame();
    }

    void shutdown(){}
    void uninstall(){}
};

#include "Robot.h"

RobotPlugin* robotPlugin = 0;

extern "C" __declspec(dllexport) void dllStartPlugin()
{
    robotPlugin = OGRE_NEW RobotPlugin;
    Ogre::Root::getSingleton().installPlugin(robotPlugin);
}

extern "C" __declspec(dllexport) void dllStopPlugin()
{
    Ogre::Root::getSingleton().uninstallPlugin(robotPlugin);
    OGRE_DELETE robotPlugin;
}

在ogreMfc工程中添加menu事件响应函数：

void COgreMfcView::OnRobotRobotmesh()
{
// TODO: 在此添加命令处理程序代码
Ogre::Root::getSingleton().loadPlugin("OgrePlugin");
}

就可以了。。。

ps：

void initialise()
{
Ogre::SceneManager* sceneMgr = Ogre::Root::getSingleton().getSceneManager("ogreMfc");
Ogre::Entity* robot = sceneMgr->createEntity("robot", "robot.mesh");
Ogre::SceneNode* robotNode = sceneMgr->getRootSceneNode()->createChildSceneNode("robot");
robotNode->attachObject(robot);
robotNode->setPosition(Ogre::Vector3(100, 0 , 0));

Ogre::AxisAlignedBox box = robot->getBoundingBox();
Ogre::Vector3 center = box.getCenter();
Ogre::Camera* camera = sceneMgr->getCamera("ogreMfcCamera");
camera->lookAt(center);

Ogre::Root::getSingleton().renderOneFrame();
}

中Ogre::Root::getSingleton().getSceneManager("ogreMfc")和

Ogre::Camera* camera = sceneMgr->getCamera("ogreMfcCamera");

2个函数的参数必须与OgreMfc工程中创建scenemgr和camera的名字一样~~~。
