# Legacy:Object (UT3)/Structs

### From Unreal Wiki, The Unreal Engine Documentation Site

UT3 :: Object (UT3) (Structs)

These structs are declared in the Object class. Apart from the structs described here, there are also a number of "mirror" structs that reflect native data structures, but do not expose any relevant features to UnrealScript.

Some of these structs are declared immutable, but this has no effect in UnrealScript.

## Box

A bounding box defined by lower back left and upper front right edges.

vector Min
vector Max
byte IsValid

## BoxSphereBounds

A bounding box and bounding sphere with the same origin.

vector Origin
  Origin of the bounding box and sphere.
vector BoxExtent
  Extend of the bounding box.
float SphereRadius
  Radius of the bounding sphere.

## Color

An RGBA color with 8 bit unsigned integer components.

See Legacy:Object (UT3)/Operators and Legacy:Object (UT3)/Functions for a list of color operations.

byte R
  Red value.
byte G
  Green value.
byte B
  Blue value.
byte A
  Alpha value.

## Cylinder

A cylinder defined by its radius and height.

float Radius
  Cylinder radius.
float Height
  Cylinder height.

Note: Traditionally the height value of an actor's collision cylinder is the distance of the bottom and top plane from the actor's center location, i.e. half the actual cylinder's height. This struct is likely used in the same fashion.

## Guid

A globally unique identifier with a length of 128 bits.

int A
int B
int C
int D

## InterpCurveType

Five types of interpolation curves, where Type is replaced by Float, Vector, Vector2D, TwoVectors and Quat respectively.

array<InterpCurvePointType> Points
EInterpMethodType InterpMethod

## InterpCurvePointType

Five types of interpolation curve points, where Type is replaced by Float, Vector, Vector2D, TwoVectors and Quat respectively.

float InVal
Type OutVal
Type ArriveTangent
Type LeaveTangent
EInterpCurveMode InterpMode

## IntPoint

Screen coordinates.

int X
  X coordinate.
int Y
  Y coordinate.

## LinearColor

An RGBA color with 32 bit floating point components.

See Legacy:Object (UT3)/Operators and Legacy:Object (UT3)/Functions for a list of color operations.

float R
  Red value.
float G
  Green value.
float B
  Blue value.
float A
  Alpha value.

## Matrix

A 4x4 matrix.

Plane WPlane
Plane XPlane
Plane YPlane
Plane ZPlane

## Plane extends Vector

A plane definition in 3D space. Since it extends Vector, it inherits the three vector components X, Y and Z.

float W

A plane can be described in its normal form by defining its normal vector consisting of the X, Y and Z components and its distance from the origin in the W component.

Alternatively the Plane struct can also describe a sphere, which is done by defining the sphere's center with the X, Y and Z components and its radius with the W component.

## Quat

A quaternion. Quaternions are used for describing rotations without Wikipedia:gimbal lock. (also see Wikipedia:Quaternion)

See Legacy:Object (UT3)/Operators and Legacy:Object (UT3)/Numeric Functions for a list of quaternion operations.

float W
  The real component. In quaternion rotations, this corresponds to the rotation angle.
float X
float Y
float Z
  The complex components. In quaternion rotations, these correspond to the normal vector describing the rotation axis.

## Rotator

An orthogonal rotation in 3D space. See Rotator.

See Legacy:Object (UT3)/Operators and Legacy:Object (UT3)/Numeric Functions for a list of rotator operations.

int Pitch
  Pitch component.
int Yaw
  Yaw component.
int Roll
  Roll component.

## TPOV

Point Of View type.

vector Location
  View location.
rotator Rotation
  View rotation.
float FOV
  FOV angle.

## TwoVectors

Two vectors.

vector v1
  First vector.
vector v2
  Second vector.

## Vector

A point or direction vector in 3D space. See Vector.

See Legacy:Object (UT3)/Operators and Legacy:Object (UT3)/Numeric Functions for a list of vector operations.

float X
  X component.
float Y
  Y component.
float Z
  Z component.

## Vector2D

A point or direction in 2D space.

float X
  X component.
float Y
  Y component.

## Vector4

A point or direction in 4D space.

float W
  W component.
float X
  X component.
float Y
  Y component.
float Z
  Z component.
