# Footstep Sound System

BFLite uses physical materials to determine footstep sounds. This lets you play different sounds when walking on surfaces like wood, metal, grass, and more — all based on Unreal Engine's surface types.

# ➕ Adding a New Surface Type

  1. Go to Project Settings → Physics → Physical Surface
  2. Click the + icon and give your new surface a name (e.g., Snow, Carpet, etc.)

# 🧱 Create a Physical Material

  1. Go to: Content/BFLite/Materials/Physical
  2. Create a new Physical Material (or duplicate an existing one)
  3. In the material details, set the Surface Type to your new surface

📌 This links your physical material to the trace logic used by footsteps

# 🧠 Changes on Character BP

  1. Open BP_Character_Base
  2. Navigate to the function: FootstepTrace
  3. Right-click on the EPhysicalSurface enum and Refresh Nodes
  4. Find your new surface and add the correct location and sound
  5. Attach your custom footstep sound to the Play sound at location
    Copy the same logic as the other surfaces

💡 You can follow the structure used for existing materials to keep things clean.

# ✅ Example Use Case

Want footsteps to crunch in snow or squish in mud?
Just create the physical material, add a sound, and link it!
