Syntax

struct FCharacterMovementComponentAsyncInput : public Chaos::FSimCallbackInput

Remarks

Contains all input and implementation required to run async character movement. Base implementation is from CharacterMovementComponent. Contains 'CharacterInput' and 'UpdatedComponentInput' represent data/impl of Character and our UpdatedComponent. All input is const, non-const data goes in output. 'AsyncSimState' points to non-const sim state.
