Choosing destinations – finding a random spawn point

Many games make use of spawn points and waypoints. This recipe demonstrates choosing a random spawn point, and then the instantiation of an object at that chosen point.

Getting ready

This recipe builds upon the previous recipe. So, make a copy of this project, open it, and then follow the steps in the next section.

How to do it...

To find a random spawn point, follow these steps:

1. In the Scene panel, create a sphere (by navigating to Create | 3D Object | Sphere) sized as (1, 1, 1) at (2, 2, 2) position, and apply the m_red Material.
2. In the Project panel, create a new Prefab (by going to Create | Prefab) named Prefab-ball, and drag your sphere into it (and then delete the sphere from the Hierarchy panel).
3. In the Scene panel, create a new capsule (by navigating to Create | 3D Object | Capsule) named Capsule-spawnPoint at (3, 0.5, 3), and give it a tag of Respawn (this is one of the default tags that Unity provides):
