To move the player by the user with the arrow keys, we need to create a Script. To create a script, perform the following steps in order:
1. Select the Player scene. While the Player Node is selected, click the second button from the right in the row under "Scene" to create a new script or connect an existing script to the selected Node.
2. Click on the button at the far right of the "Path" line in the window that opens.
3. After opening the "scripts" directory in the window that opens, open the "player.gd" file by clicking the "Open" button.
4. In the previous window, click the "Create" button.
5. A file named "player.gd" is created under the "scripts" directory under the "FileSystem" tab.
6. Save the scene with the Ctrl-S keys.
When we run the program, the Player falls down.
