Shooting projectiles

Shooting mechanics are so common that it's hard to think of a first-person game without some variation present, and Hero Born is no different. In this section, we'll talk about how to instantiate GameObjects from Prefabs while the game is running, and use the skills we've learned to propel them forward using Unity physics.

Instantiating objects

The concept of instantiating a GameObject in the game is similar to instantiating an instance of a class—both require starting values so that C# knows what kind of object we want to create and where it needs to be created. To create objects in the scene at runtime, we use the Instantiate() method and provide a Prefab object, a starting position, and a starting rotation.

Essentially, we can tell Unity to create a given object with all its components and scripts at this spot, looking in this direction, and then manipulate it as needed once it's born in the 3D space. Before we instantiate...
