Time for action — creating a blank sheet

  1. First we need to include ExampleApplication:
    #include "OgreExampleApplication.h"
  2. Create a new application class that inherits from ExampleApplication and has an empty createScene() function:
    class Example41 : public ExampleApplication
{
public:
void createScene()
{
}
};
  3. Lastly, we need a main function that creates an instance of the application class and runs it:
    int main (void)
{
Example41 app;
app.go();
return 0;
}
  4. Compile this project with the same include and libraries directories as we did previously, and link the same libraries. You should get a black window which can be closed by pressing Escape.

What just happened?

We created a new application which inherits from ExampleApplication and does nothing. It has an empty createScene() function because this is a pure virtual function in the base class and if we don't override it we can't instantiate our class. The more interesting part of the application will be added now.
