cocos2d-x 初学者的困惑

1、如何设置cocos2d-x 背景透明
参考了此博客点击访问

在以下代码块添加 glClearColor

void Director::setGLDefaultValues()
{
    // This method SHOULD be called only after openGLView_ was initialized
    CCASSERT(_openGLView, "opengl view should not be null");

    setAlphaBlending(true);
    setDepthTest(false);
    setProjection(_projection);

    //here to clear color
    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);

}

    glClearColor(0.0f,0.0f,0.0f,0.0f); // add it to make 3D transparent  
  
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //add code bofore here 
    /* to avoid flickr, nextScene MUST be here: after tick and before draw.
     * FIXME: Which bug is this one. It seems that it can't be reproduced with v0.9
     */
    if (_nextScene)
    {
        setNextScene();
    }

2、如何编译一个cocos2d工程针对android-studio

cocos compile -p android android-studio

在命令行里直接输入 cocos --help可以查看相关命令的使用帮助

3. 如何命令行建立一个工程

cocos new -p(package name) com.cocos.demo -l(language) cpp
