Unity Tutorial - 3D Spinning Cube in 10 minutes

Edit a script

Let's make the cube spin now.

Let's start writing a script to rotate the cube by creating a variable that will control the rotation.

• Insert the highlighted line of code above the Start method. This code creates a public Vector 3, with x,y,z coordinates that will control the rotations in a 3D space.

  C#Copy

  public Vector3 RotateAmount;
  // Start is called before the first frame update
  void Start()
  {

• Then add the highlighted line of code inside the Update method. Every game object in Unity has a Transform script that dictates where it exists in 3D space and its rotation in 3D space. You'll use the Rotate method here and specify the rotation amount you want to happen on that game object.

  C#Copy

  // Update is called once per frame
  void Update()
  {
  	transform.Rotate(RotateAmount);
  }

• Now, go back to the Unity editor and choose the Cube object in the Hierarchy window again.

• On the Inspector window, you should find that the Public variable you've created is now visible under the new script you added to the cube.

• Change the Y value to 1, and then press the Play button on the top and center of the Unity editor.

  Since the Update method runs every frame, you'll see that the cube will rotate by one for every frame. Feel free to change those values up and have some fun. You're now ready to build the game for different platforms.
