Our animal prefabs walk across the screen and get destroyed out of bounds, but they don’t actually appear in the game unless we drag them in! In this live session, we will allow the animals to spawn on their own, in a random location at the top of the screen. In order to do so, we will create a new object and a new script to manage the entire spawning process.
1. Overview
This is the same content covered in Lesson 2.3 in the independent Create with Code Course.
What you will make:
- When the user presses the S key, a randomly selected animal will spawn at a random position at the top of the screen, walking towards the player.
What you will learn:
- Create an empty object with a script attached
- Use arrays to create an accessible list of objects or values
- Use integer variables to determine an array index
- Randomly generate values with Random.Range in order to randomize objects in arrays and spawn positions
- Change the camera’s perspective to better suit your game
2. Before you Begin
To participate in this session and follow along, you need:
- Unity 2018.4 installed
- An up-to-date project open in Unity:
- If you have followed along with us this week and have your own project ready, you are good to go!
- You can also download the instructor's up-to-date project and import it (If you don't know how to import a project, you can read how here)
If this is your first Create with Code live learning session, you can catch up by:
- Following along with the recordings of our previous live learning sessions
- Completing the same lessons in the independent Create with Code Course
*Note - it is not necessary for you to catch up, but it is recommended for an ideal learning experience.
