High Speed Chase

Keep your eyes on the road! In this lesson you will code a new C# script for your camera, which will allow it to follow the vehicle down the road and give the player a proper view of the scene. In order to do this, you’ll have to use a very important concept in programming: variables.

Add a speed variable for your vehicle

  1. In PlayerController.cs, add public float speed = 5.0f; at the top of the class
  2. Replace the speed value in the Translate method with the speed variable, then test
  3. Save the script, then edit the speed value in the inspector to get the speed you want

Create a new script for the camera

  1. Create a new C# script called FollowPlayer and attach it to the camera
  2. Add public GameObject player; to the top of the script
  3. Select the Main Camera, then, drag the player object onto the empty player variable in the Inspector
  4. In Update(), assign the camera’s position to the player’s position, then test

​

Add an offset to the camera position

  1. In the line in the Update method add + new Vector3(0, 5, -7), then test

​

Make the offset into a Vector3 variable

  1. At the top of FollowPlayer.cs, declare private Vector3 offset;
  2. Copy the new Vector3() code and assign it to that variable
  3. Replace the original code with the offset variable
  4. Test and save

Smooth the Camera with LateUpdate

  1. Test your prototype to notice the jittering camera as the vehicle drives.
  2. In FollowPlayer.cs, replace Update() with LateUpdate().
  3. Save and test to see if the camera is less jittery.

Edit the playmode tint color

  1. From the top menu, go to Edit > Preferences (Windows) or Unity > Preferences (Mac)
  2. In the left menu, choose Colors, then edit the “Playmode tint” color to have a slight color
  3. Play your project to test it, then close your preferences
