UGantryInputMappingSubsystem

#include "Input/GantryInputMappingSubsystem.h"

Adds and removes Enhanced Input mapping contexts on one local player, counting who holds each one.

Two experiences, such as a game mode and a DLC pack that extends it, may both add the same mapping context. The player gets it once, and it comes off only when the last of them removes it. The Add Input Mappings stage (UGantryExperienceStage_InputMappings) uses this for you. Call it yourself for contexts your own code turns on and off, such as a vehicle's controls.

Adding can also register the context for rebinding with Enhanced Input's player settings, so a key binding setting (UGantrySettingKeyBinding) can list and rebind its keys.

Gantry binds no actions. What an action does is up to your game.
