Wheel Skid Component

WheelSkidComponent Inspector

Tire skid/squeal sound during hard braking and drifting. Plays when wheel slip exceeds threshold.

Implementation

Gets audio clip and settings from SurfacePreset based on dominant surface. Volume scales with normalized wheel slip and speed coefficient. Checks all wheels and uses highest volume value.

Volume calculation: slipPercent * skidSoundVolume * speedCoeff

  • slipPercent: Combined normalized lateral + longitudinal slip (0-1)
  • speedCoeff: Min(1, vehicleSpeed * 0.33 + wheelAngularVelocity * 0.05)

Triggers when:

  • isSkiddingLaterally (drifting, cornering)
  • isSkiddingLongitudinally (hard braking, burnout)
  • Wheel grounded

Configuration

SurfacePreset (per surface type):

  • skidSoundClip: Audio clip to play
  • skidSoundVolume: Volume multiplier (default 0.3)
  • skidSoundPitch: Pitch multiplier (default 1.0)
  • playSkidSounds: Enable/disable flag

Component: Surface Noise Mixer Group, Priority 60, Looping, single AudioSource

Setup

  1. Configure Ground Detection with surface presets
  2. Assign skid clips to each surface (asphalt = high-pitched squeal, gravel = grinding, etc.)
  3. Enable in SoundManager
  4. Test with drifting and hard braking

Troubleshooting

No sound: Check Ground Detection has dominant surface, verify skidSoundClip assigned, confirm playSkidSounds enabled in SurfacePreset

Volume too low/high: Adjust skidSoundVolume in SurfacePreset (default 0.3)

Wrong surface sound: Verify Ground Detection identifies correct dominant surface

Note: Uses single AudioSource for all wheels with volume smoothing (10x delta time lerp).
