Lesson 3.2 - Make the World Whiz By

Create a script to repeat background

  1. Create a new script called RepeatBackground.cs and attach it to the Background Object

Reset position of background

  1. Declare a new variable private Vector3 startPos;
  2. In Start(), set the startPos variable to its actual starting position by assigning it = transform.position;
  3. In Update(), write an if-statement to reset position if it moves a certain distance

Fix background repeat with collider

  1. In PlayerController.cs, declare a new private Rigidbody playerRb; variable
  2. In Start(), initialize playerRb = GetComponent<Rigidbody>();
  3. In Start(), use the AddForce method to make the player jump at the start of the game

​Make player jump if spacebar pressed

​
  1. Add a Box Collider component to the Background
  2. Declare a new private float repeatWidth variable
  3. In Start(), get the width of the box collider, divided by 2
  4. Incorporate the repeatWidth variable into the repeat function

Add a new game over trigger

  1. In the inspector, add a “Ground” tag to the Ground and an “Obstacle” tag to the Obstacle prefab
  2. In PlayerController, declare a new public bool gameOver;
  3. In OnCollisionEnter, add the if-else statement to test if player collided with the “Ground” or an “Obstacle”
  4. If they collided with the “Ground”, set isOnGround = true, and if they collide with an “Obstacle”, set gameOver = true

Stop MoveLeft on gameOver

  1. In MoveLeft.cs, declare a new private PlayerController playerControllerScript;
  2. In Start(), initialize it by finding the Player and getting the PlayerController component
  3. Wrap the translate method in an if-statement checking if game is not over

Stop obstacle spawning on gameOver

  1. In SpawnManager.cs, get a reference to the playerControllerScript using the same technique you did in MoveLeft.cs
  2. Add a condition to only instantiate objects if gameOver == false

Destroy obstacles that exit bounds

  1. In MoveLeft, in Update(); write an if-statement to Destroy Obstacles if their position is less than a leftBound variable
  2. Add any comments you need to make your code more readable
