When the game window is smaller than the game map, we need to create a camera centered on the Player's location on the game map to transfer the area from the map to the game window with the size of game window and to shift the area to be shown in the game window as the Player moves. To create a camera, perform the following steps in order:
1. While the Game Node is selected, create a new Node by clicking the + sign under the Scene tab or by pressing the Ctrl-A keys .
2. In the Create New Node window that appears, search for and select Camera2D in the Search line and click on the Create button.
3. While the "Camera2D" Node is selected, set the "Zoom" value of the "Inspector" tab to 4.
The zoom value will enlarge the images in the game window by 4 times.
4. The rectangle representing the camera appears on the stage. Center the camera on the Player.
5. Save the Game scene with Ctrl-S and run the game.
