第二步：添加files
Step 1 选择Project－》Add Existing Item
Step 2 找到tornado.cpp，将该文件放在项目所在目录。
第三步：配置project
Step 1 选择Projects－》Properties
Step 2 在Properties属性列表里，在Configuration下拉列表中选择All Configurations :
Step 3 选择C/C++标签 Step 4 点击Code Generation
Step 5 在runtime library右侧下拉列表中选择Multi-threaded DLL(/MD)

这个是教程的方法，我想请问的是第二步中的“找到tornado.cpp，将该文件放在项目所在目录。”，这个CPP是由LP输出的吗？也就是在LP中点击file，然后Export cpp file.但这个输出的CPP和我在教程中的tornado.cpp完全不一样，请问这个是为什么啊

大侠们解释一下嘛，困惑中，自己在LP中做的东西，在vs2003上没有显示啊。。。。

导出的CPP包含MAIN函数，直接配置运行。研究透了再改造。

    我按照例子做的tornado.acf，用LP生成的.CPP和文档提供的.CPP完全不一样，除了主函数以外，这个又是为什么呢？我主要是想在LP下实现一些我用LP就能够实现的东西，然后在编程实现LP不能够实现的东西，这样我可以省下很多时间

有什么不一样？  都在DEFINE函数里面。

虽然加入这两个代码都可以让其运行起来，但为什么会对同一个ACF得出的代码不同呢，这是不懂的地方，谢谢你的耐心解释哈

if (argc <= 1)
        app->define("vp_pixel_buffer.acf");
    else app->define(argv[1]);
这里使用了ACF文件，就相当于导出文件里面的define函数
本质上，7楼是纯粹的CPP代码，没有使用ACF文件，而6楼使用了ACF文件。

换句话说就是，如果能够在LP中实现，形成.acf文件，那.cpp直接用以下代码就可以了，不用在编程了，对吧？
int main(int argc, char *argv[])
{
    // initialize vega prime
    vp::initialize(argc, argv);

    // create my app instance
    myApp *app = new myApp;

    // load the acf file
    if (argc <= 1)
        app->define("vp_pixel_buffer.acf");
    else app->define(argv[1]);

    // configure my app
    app->configure();

    // execute the main runtime loop
    app->run();

    // delete my app instance
    app->unref();

    // shutdown vega prime
    vp::shutdown();

    return 0;
}
编程只是为了在现有框架下实现在LP中实现不了东西，我这个说法对吗？

可以这么说。完全看项目需求和开发者的习惯。
但很多时候，必须采用编程的方式来控制才能实现要求。

谢谢了哈。。。

LP的源代码怎么在VS2003中生成的啊，还有如果改变了源代码是不是就能改变运动状态啊

LP的源代码怎么在VS2003中生成的啊，还有如果改变了源代码是不是就能改变运动状态啊 ...
hejinzheng 发表于 2010-8-12 06:50 PM

    在LP中有生成C++源代码这一选项，LP只是能够配置基本的运动状态，复杂的运动状态需要添加代码俩实现

谢谢啦，现在明白了，就是代码有点麻烦，都是类
