How to set button focus in Unity 3D?

In the dynamic world of Unity 3D development, mastering the art of user interaction is crucial. One such essential aspect is setting button focus, ensuring your game’s controls are intuitive and responsive. Let’s delve into this topic, uncovering tips, tricks, and best practices to elevate your Unity 3D projects.

Why Button Focus Matters

Imagine a game where the player can’t interact with buttons because they’re not in focus. Frustrating, isn’t it? Good button focus is like a well-oiled machine; it ensures smooth and efficient user interaction, enhancing the overall gaming experience.

The Focus OnFocus Method

Unity 3D provides a built-in method called `OnFocus()` and `OnLostFocus()`. These functions are attached to UI buttons, allowing you to customize their behavior when they gain or lose focus.
