// for the controller haptics
void onControllerFeedback (position(Left|Right), durationMills: int, frequency: int, intensity(0~1): float, metaData(e.g. weaponType)) 

// head shot
void onHeadShot(horizontalAngle(0~360), durationMillis: int, frequency: int, intensity(0~1) : float, metaData(e.g. bulletType, fade in/out))

// body shot 
void onBodyShot(horizontalAngle(0~360), verticalOffset(-0.5~0.5), durationMills: int, frequency: int, intensity(0~1), metaData(e.g. bulletType, fade in/out))

This video shows how horizontalAngle and verticalOffset are working.
