First you define your USTRUCT, above your class definition (or in a static library)

```auto

USTRUCT()
struct FSixenseControllerData
{

	GENERATED_USTRUCT_BODY()

	UPROPERTY()
	float pos[3];
	
	UPROPERTY()
	float rot_mat[3][3];
	
	UPROPERTY()
	float joystick_x;
	
	UPROPERTY()
	float joystick_y;
	
	UPROPERTY()
	float trigger;
	
	UPROPERTY()
	unsigned int buttons;
	
	UPROPERTY()
	unsigned char sequence_number;
	
	UPROPERTY()
	float rot_quat[4];
	
	UPROPERTY()
	unsigned short firmware_revision;
	
	UPROPERTY()
	unsigned short hardware_revision;
	
	UPROPERTY()
	unsigned short packet_type;
	
	UPROPERTY()
	unsigned short magnetic_frequency;
	
	UPROPERTY()
	int enabled;
	
	UPROPERTY()
	int controller_index;
	
	UPROPERTY()
	unsigned char is_docked;
	
	UPROPERTY()
	unsigned char which_hand;
	
	UPROPERTY()
	unsigned char hemi_tracking_enabled;
 
        //You must include constructor
       FSixenseControllerData()
       {
           //your default values
       }
	
};

```

Now it is an official variable type that you declare inside your class

```auto

UPROPERTY()
FSixenseControllerData MySixthSense;

```

```auto

F

all struct types must start with F 

```
