Assembly: NWH.VehiclePhysics2.dll

Syntax

[RequireComponent(typeof(MeshRenderer))]
public class SkidmarkDestroy : MonoBehaviour

Remarks

Attached to each skidmark section GameObject to automatically clean up old skidmarks based on distance from the vehicle or elapsed time. When triggered, the skidmark fades out over a period before being destroyed to prevent sudden disappearance. Checks conditions periodically (every second) rather than every frame for performance.

Fields

destroyFlag

When set to true, forces the skidmark to fade out and be destroyed on the next check cycle. Used by SkidmarkManager to manually trigger cleanup when exceeding total triangle limits.

Declaration

[Tooltip("Set to true to trigger the fade out and destroy even with the next check.")]
public bool destroyFlag

Field Value

Type	Description
bool

distanceThreshold

Maximum distance in meters from the target transform before triggering destruction. Skidmark begins fading when this distance is exceeded. Set to 0 to disable distance-based cleanup.

Declaration

[Tooltip("Distance at which the GameObject will be destroyed.")]
public float distanceThreshold

Field Value

Type	Description
float

skidmarkIsBeingUsed

Indicates whether this skidmark section is still actively receiving new geometry from the generator. While true, destruction checks are skipped. Set to false by the generator when moving to a new section.

Declaration

[Tooltip("True if the skidmark is still the currently active skidmark")]
public bool skidmarkIsBeingUsed

Field Value

Type	Description
bool

targetTransform

The wheel transform used for distance calculations. Skidmark distance is measured from this transform's position. Typically set to the generating wheel's transform.

Declaration

[Tooltip("Transform to which the object belongs to.")]
public Transform targetTransform

Field Value

Type	Description
Transform

timeThreshold

Maximum lifetime in seconds before triggering destruction. Skidmark begins fading when this age is exceeded. Set to 0 to disable time-based cleanup.

Declaration

[Tooltip("Time after which the GameObject will be destroyed.")]
public float timeThreshold

Field Value

Type	Description
float
