Adding gun turrets

Creating a gun turret involves creating several objects and scripts. We can't just create the turret object. We also need to create the projectiles that will be fired from the turret, script the projectiles so that they move when spawned, and finally create a script for the turret to spawn the projectiles at regular intervals. Let's start by creating the turret object.

Constructing the gun object

Instead of using an image file for our turrets, as we have previously for the player and level objects, we'll create the turret using a primitive shape:

1. Double-click scene_Level03 in the Project panel to open it The Scene_Level03 can be found in the project included in the Chapter07/Start folder at https://github.com/PacktPublishing/Unity-2020-By-Example-Third-Edition.
2. Create a new cube object (GameObject | 3D Object | Cube) and name it as Turret:

3. Adjust the object's scale to approximate a gun turret...
