Struct PhysicsWorldHistory

A system used to store old state of the physics world for lag compensation. This system creates a PhysicsWorldHistorySingleton and from that you can get a physics collision world for a previous tick.

public struct PhysicsWorldHistory : ISystem, ISystemCompilerGenerated
Remarks

This clone of the PhysicsWorld occurs shortly after building the physics world, to ensure that collider BlobAssetReferences are valid and correctly copyable.

Fields

RawHistoryBufferMaxCapacity

Max quantity of CollisionWorld's that can be stored in the RawHistoryBuffer.

Declaration
public const int RawHistoryBufferMaxCapacity = 32
Field Value
Type Description
int
Remarks

Lag compensation queries that attempt to reach further back than the capacity will be clamped to the oldest. The previous value was 16.
