EVENT API

The Microsoft Flight Simulator 2024 Event API permits you to trigger different kinds of key events. This API replaces some features provided by the deprecated Gauge API.

 

The functions available for this API are as follows:

 

Function	Description
fsEventsTriggerKeyEvent	Trigger a Key Event.
fsEventsRegisterKeyEventHandler	Register a Key Event handler which will receive all Key Events raised by the simulation.
fsEventsUnregisterKeyEventHandler	Unregister a Key Event handler that has been previously registered.

 

You can find a sample project to use as a reference when using the Event API here:

Typedefs

When using this API the following typedefs exist to help:

 

 

FsEventId

The ID of an Event. The list of all available IDs can be found in MSFS/Types/MSFS_EventsEnum.h.

typedef int FsEventId;

 

 

FsEventsKeyEventHandler

Callback signature for the key event handler, where:

typedef void(*FsEventsKeyEventHandler)(FsEventId eventId, FsVarParamArray* param, void* userParam);

• eventId: Id of the received event.
• param: values received with the event. Value can be index or FsCRC. To manage this type, helper functions can be found in MSFS/Utils/SimParamArrayHelper.h.
• userParam: pointer data that will be given to the user who has register the handler
