C++ (Cpp) Window::Flip Examples

Example #1

File: Game.hpp Project: grandmasterhack/1GAM

int UpdateMenu(Window &App)
{
    App.FPS =60;
    Uint8 *Key;
    SDL_Event Event;
    bool Running = true;

    while(Running)

            }
        }

            return 1;
        }
        if( Key[SDLK_ESCAPE])
        {
            return 20;
        }

        App.LimitFramerate();
        App.Flip();
        App.RenderText();

        App.Clear();
    }
