Ogre1.73学习实例.doc

DirectX使用的是左手坐标系x正向右,y正向上,z正向前,即向屏幕里Ogre/OpGL 使用的是右手坐标系 x正向右,y正向上,z正向自己,即向屏幕外以下 开发工具为 Visual Studio 2010， DirectX版本为：Microsoft DirectX SDK (June 2010) Ogre版本为：OgreSDK_vc10_v1-7-3注意：要想Ogre程序能运行,必须将Ogre库的dll文件路径配置进环境变量：一：9个实体,随机出现一个,隐藏另一个,鼠标移到转动相机,按键盘移动相机.(程序为 游戏类编程/Ogre/Ogre1.73/FirstOGRE) 1：新建一个空的 win32控制台应用程序，命名为：FirstOGRE 2：添加一个 FirstOGRE.cpp文件 3：配置 包含目录(包含Ogre的头文件的目录) 和 库目录(包含Ogre的lib文件的目录)：包含目录： 库目录： 4：配置 附加依赖项： OgreRTShaderSystem_d.libOgreMain_d.libOIS_d.lib 5：将OgreSDK_vc10_v1-7-3安装目录下的 media目录拷贝到 当前工程目录下，将OgreSDK_vc10_v1-7-3安装目录下的 bin目录下 的 debug目录下和 release目录的下 后缀为 .cfg的文件拷贝到当前目录下, 并修改.cfg文件内的配置内容(修改配置路径的内容)： 6：添加一个 MyEntity MyEntity.h：#ifndef MyEntity_H_#define MyEntity_H_#include class MyEntitypublic:MyEntity(Ogre:SceneManager* mSceneMgr, int i, int j);/创建实体,节点,并为节点创建动画.MyEntity(void);public:void update(float interval);/ 动画void enable();
