4. Back in the Unity Editor add the ProjectileLauncher script component to the Cannon GameObject using the Add Component button.

5. Turn the Sphere_Small GameObject into a prefab by dragging it into the Project window.

6. Add the newly create Sphere_Small GameObject to the Projectile Launcher Component’s Projectile Prefab field.

7. Adjust the Launch Power to 2000. Note if you modify the Projectile Prefab’s RigidBody component you may need to adjust the Launch Power to compensate.

8. Add the ProjectileSpawnPoint to the Cannon’s Projectile Launcher component’s projectile spawn location field

9. To trigger the Launch method, select the target object (Cannon > Target) and in the Target Collision component, click the + button to a new event.

10. Configure the new event by dragging the Cannon GameObject into the event field, and selecting the ProjectileLauncher.Launch method. This will call the Launch method when a collision occurs.
