Unreal - Movement

Movement is split between a few components.

Engine/Source/Runtime/Engine/Classes/GameFramework/PlayerController.h

UPlayerController handles input modes and events.

• Contains a rotation to represent a players rotation
  • AddPitchInput(float Val)
  • AddYawInput(float Val)
  • AddRollInput(float Val)
• Contains functions and events for handling input
  • IsInputKeyDown(FKey Key)
  • WasInputKeyJustPressed(FKey Key)
  • GetInputVector / GetInputAnalogKeyState / GetMousePos

Takes a normalised movment input vector in order and then calculates the output velocity of the Actor it is attached to.

• Inherits from UNavMovmentComponent to allow AI Pathfinding Useful functions exist that can be overloaded
  • virtual void RequestPathMove(const FVector& MoveInput) override;
  • virtual void RequestDirectMove(const FVector& MoveVelocity, bool bForceMaxSpeed) override;
  • virtual bool CanStartPathFollowing() const override;
  • virtual bool CanStopPathFollowing() const override;
  • virtual float GetPathFollowingBrakingDistance(float MaxSpeed) const override;

Used by the AI Module to determine the next control input needed to move to an actor directly, or to follow a path from the navigation system.
