Lesson 1.3 - 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

The camera will follow the vehicle down the road through the scene, allowing the player to see where it’s going. 

We need an easier way to change the vehicle’s speed and allow it to be accessed from the inspector. In order to do so what we need is something called a variable.

, assign the camera’s position to the player’s position, then test

Create a new script for the camera

We need to move the camera’s position above the vehicle so that the player can have a decent view of the game.

Add an offset to the camera position

We’ve fixed the camera’s position, but we may want to change it later! We need an easier way to access the offset.

Make the offset into a Vector3 variable

You may have noticed that the camera is kind of jittery as the car drives down the road - let’s fix that.

Test your prototype to notice the jittering camera as the vehicle drives.

Smooth the Camera with LateUpdate

If we’re going to be creating and editing variables, we need to make sure we don’t accidentally try to make changes when in “Play mode”

In the next lesson, we’ll add our last lines of code to take control of our car and be able to drive it around the scene.

By the end of this lesson, you will be able to:

Declare variables properly and understand that variables can be different data types (float, Vector3, GameObject) 

Initialize/assign variables through code or through the inspector to set them with appropriate values

Use appropriate access modifiers (public/private) for your variables in order to make them easier to change in the inspector

Use the Update and LateUpdate appropriately in order to call one action after another has already happened
