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.

Now, we are going to develop a new script that will make it possible to select the units, which is fundamental to giving them an action to perform, such as moving or attacking a target.

We are going to add a few new debugging options to our game to make it possible to enable or disable the camera movement with the mouse, as well as add shortcuts to spawn new units. Then, we are going to start preparing the UI by adding a few new GameObjects to our LevelManager Prefab, and also create visual feedback in the UI to help the player see what is being selected using the mouse on the map.

Adding more debug options

Before creating the script responsible for selecting the units, we will need to make some adjustments to the project. The first...
