Game Design Patterns: Flyweight

Using the flyweight pattern is a great way to optimize performance in your game, especially concerning large volumes of prefabs (reusable objects) and script instances. When using prefabs, you can save performance by reusing a copy of that object. While each instance of that object has a shared material, and uses the same script, it still creates a unique instance of that script. When working with thousands, or tens of thousands of reusable objects with shared variables, the flyweight pattern is a good solution for coupling the shared properties that will remain the same between all instances. Let’s use an Enemy script as an example, assuming you may have 20,000 enemies in your scene at once. They all have a max, min and current health variable, a speed variable, a handle to the player’s transform component, and a wait time for a coroutine. <a href="https://levelup.gitconnected.com/game-design-patterns-flyweight-b087cabb457">Learn More</a>
