How do I use physics layers in Unity 2D?

In Unity 2D, physics layers help you manage collisions and interactions between different objects. You can set up layers in the 'Layer' dropdown in the Inspector.

Can you explain how to set up collision detection with these layers?

Sure! You can define which layers interact with each other by going to 'Edit' > 'Project Settings' > 'Physics 2D' and adjusting the Layer Collision Matrix.

What are some common use cases for physics layers?

Common use cases include separating player characters from enemies, managing projectiles, and controlling environmental interactions like traps.

Is there a way to visualize these layers in the scene?

Yes, you can use Gizmos to visualize layers in the Scene view. Just enable Gizmos in the Scene view toolbar and customize your objects to show their layer.
