#include "Factory.h"
#include "LevelUpdate.h"
#include "PlayerGraphics.h"
#include "PlayerUpdate.h"
#include "InputDispatcher.h"
#include "CameraUpdate.h"
#include "CameraGraphics.h"

Now add the following code for the first camera. Add all the camera code after the code that handles the player, at the very end (but inside) of the loadLevel function. Note that the first couple of lines are for both cameras; we will get to the second camera next. The regular full-screen camera is added first; otherwise, it would hide the mini-map camera.

// For both the cameras
const float width = float(VideoMode::getDesktopMode().width);
const float height = float(VideoMode::getDesktopMode(...
