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.

Updating the UI using the Message Queue pattern

The Message Queue pattern, also known as the Event Queue pattern, consists of a list of messages that are sent to all other scripts that are listening for a specific message. This is a powerful pattern that helps to decouple different scripts since you can just send a message with an update and the listener will receive and process it, without having shared variables across the whole project.

It also has good performance since the listeners are not checking for new messages on every loop. When a message is received, the message queue will trigger the listeners that are assigned to the type of message received.

We are going to implement the Message Queue pattern and use it to update the game UI and spawn new units. The idea is that when a new unit is required to be added to the game, a message will be sent by the script requesting it and received by the script that will then get a unit from the Object Pool. Both patterns work together...
