Heap allocations can quietly sabotage your Unity game’s performance, especially when closures and delegates are used incorrectly. In this video, we dive into how closures capture variables, why this often results in hidden allocations, and the impact it has on your game’s smoothness. You’ll learn how to identify and fix these issues, with a step-by-step guide to creating a lightweight Closure struct that eliminates unnecessary heap usage. Whether you're optimizing loops, avoiding stutters, or simply looking to write more efficient Unity code, this video has the practical tips you need to take control of closures and delegates.
