### Class Details

**Defined in:** Public/Objects/ExistentBodyCalibration.h

**Hierarchy:** *Object > Subsystem > DynamicSubsystem > EngineSubsystem > ExistentBodyCalibration*

Existent Body Calibration

The ExistentBodyCalibration subsystem allows to save and load per user body calibration settings. Whenever one of the Add functions is called (e.g. AddEyeHeight) a file is created or updated in the \[GAME]/Config/BodyCalibration folder. The file is named using the Player Unique Identifier parameter.

The calibration file is a JSON file which mirrors the struct FBodyCalibrationPlayer and contains the following properties:

* FString PlayerUniqueIdentifier => The unique identifier that represents the player.
* FString FriendlyName => Friendly name that represents the player.
* float EyeHeight => The eye height of the player in cm. Measure from the floor to the eye height.
* float ShoulderWidth => The shoulder width of the player in cm. Measure from shoulder to shoulder.
* float ArmsLength => The arms length/span of the player in cm. Measure this in a T pose from hand wrist to hand wrist.
* float HandSize => The hand size in cm. Measure from the wrist to middle fingertip with the hand fully open.
* float LegLength => The leg length in cm. Measure from the waist to the ankle.
