Simplify Game Damage Logic with Interfaces: How to Code Damageable Objects Efficiently In Unity
In this tutorial, I’ll walk you through creating a flexible damage system for a game using interfaces in code. Here, we start by setting up three damageable objects—a barrel, a zombie, and a boss—and dive into how each of these has a unique "Take Damage" function to reduce health when attacked.
In my player script, pressing the left mouse button triggers an attack using an "Overlap Sphere" that checks for collisions with these objects. For each collision, we detect the correct script and apply damage, making the health of each object decrease accordingly. However, this method quickly becomes inefficient if we add many types of damageable objects. That’s where interfaces come to the rescue!
I’ll show you how to create an IDamageable interface, which allows all damageable objects to share a common "Take Damage" method. Now, instead of checking each object's specific script, our code simply calls the IDamageable interface, making it easy to add new enemies without rewriting the player attack code.
