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.

The minimap is one of the most important resources for the player to master an RTS game. It shows a top view of the level and the discovered areas and it can track the enemy movements and highlight where the player is now. In this chapter, we are going to set up the minimap UI and the new camera to display the current level in the minimap. In later chapters, with more data available and game mechanics implemented, we will add more features to the minimap, so we need a solid foundation now.

So, we just learned how to use the Render Texture to display the camera render in a texture, and then add that texture to the UI. Now we are going to do the same process again but with a new Render Texture, Material, and Camera.

As we did previously, we can start creating the Render Texture and the Material that will be used by the minimap in the UI:

  1. Right-click on the Textures folder and select Create | Render Texture. You can name it MiniMapRenderTexture.
  2. ...
