Firing projectiles in the direction of movement

Another common use of force is to apply a force to a newly instantiated object, making it a projectile travelling in the direction the Player's GameObject is facing. That's what we'll create in this recipe. The result of following this recipe should look as follows:

Getting ready

This recipe builds upon the player-controlled 3D cube Unity project that you created at the beginning of this chapter. So, make a copy of this project, open it, and then follow the steps for this recipe.

How to do it...

To fire projectiles in the direction of movement, follow these steps:

1. Create a new Sphere GameObject (by navigating to Create | 3D Object | Sphere). Set its size as (0.5, 0.5, 0.5).
2. Add a RigidBody component to the Sphere (go to Physics | RigidBody).
3. In the Project panel, create a new blue Material named m_blue (go to Create | Material).
4. Apply the m_blue Material to your sphere.
5. In the Project panel, create a new Prefab named prefab_projectile.
6. Drag the sphere...
