Create a new script
0
The first script that you create for this game is going to control the player character’s movement, which is a key functionality for the game.
To create a new script, follow these instructions:

  1. In the Project window, go to the root Assets folder.
  2. Right-click an empty space and select Create > Folder. Name your new folder “Scripts”.
  3. Open the Scripts folder, then right-click and select Create > C# Script.
  4. Name your new script “PlayerController”.
  5. Double-click PlayerController to open the script file in your default IDE (integrated development environment). This will be Visual Studio unless you have set an alternative default IDE on your computer.
    From this tutorial, I click open or double click, but VS program does not open or respond at all.
