Unity Physics Layers

Physics calculations can become expensive.

Using layers improves efficiency.

Layer-Based Collisions

Unity allows you to define which layers interact.

Example:

• Player interacts with enemies
• Bullets ignore UI elements

Benefits

• Reduced collision checks
• Improved performance
• Better control

Setup

Use the Physics Matrix in Unity settings to define interactions.

Final Thoughts

Physics layers are essential for optimized collision systems.

Configure them early.
