UChaosCharacterWalkingExecutor

API > API/Plugins > API/Plugins/ChaosMover

UChaosCharacterWalkingExecutor: a concrete UChaosMoveExecutorBase that applies walking physics to the Chaos character ground constraint simulation.

This executor also implements IChaosCharacterMovementModeInterface and IChaosCharacterConstraintMovementModeInterface. When used inside a UChaosCompositeMovementMode, CollectSimulationInterfaces automatically exposes those interfaces to the simulation.

The physics application logic (ExecuteMove_Async) is equivalent to UChaosWalkingMode::SimulationTick_Implementation. Move generation is intentionally left to the paired UChaosMoverSourceBase — use UChaosLayeredMoveSource or a custom subclass to drive the proposed velocity each tick.

OnModeRegistered resolves TargetHeight and QueryRadius from the owning character and locates the shared movement settings — all on the game thread before simulation begins.
