Overview of this book

Building a successful real-time strategy game is challenging, because of both the complex mechanics and the need to strike a balance between different elements, ensuring that players enjoy creating and executing strategies against the game's AI. Creating an RTS Game in Unity 2023 will teach you how to install and set up the Unity game engine, create a new 3D project, and build a level editor to make it easier to modify and add maps to a game. The RTS game will start to take shape while you learn to implement different core systems such as melee and ranged battles, unit spawners, camera controls, dynamic mapping generation, basic enemy AI, and the pathfinder algorithm. You'll also get to grips with implementing command units to perform actions, crafting and producing resources, basic physics and collision detection, and building an RTS game from scratch using C# and the latest features of the Unity game engine. By the end of this book, you’ll be able to make professional and high-quality end-to-end RTS games using the best practices and techniques from the gaming industry.

Adding a new layer and updating cameras

We are going to need a few things to set up the fog, which includes creating a new layer, a new material, a new mesh, and a new script that will manipulate the material color using Raycast and update a couple of existing scripts in the project. Let us start with the new layer that will be used to render the fog:

  1. Open the Project Settings window using the Edit | Project Settings… menu option.
  2. On the left panel, click on Tags and Layers, and, on the right panel, expand the Layers...
