Delegates, Events, and Closures in Unity — Finally Explained
Delegates are at the core of Unity’s event systems, input, UI, and many popular libraries — but they’re often misunderstood. In this video, we break down what delegates actually are, how Unity builds on them with events and UnityEvents, and why closures can quietly introduce allocations and lifetime issues. We’ll walk through real Unity examples, show how inversion of control improves game architecture, and finish with a practical pattern used by libraries like PrimeTween to avoid closures entirely. If you want clean, flexible, and allocation-aware Unity code, this video is for you.
