Legacy:Built-In Structs (UT)

These structs are declared in Object and can be used everywhere in UT's UnrealScript.

Many of these have operators defined for them.

GUID

A globally unique identifier.

<uscript> struct Guid { var int A, B, C, D; }; </uscript>

Vector

A point or direction vector in 3d space.

<uscript> struct Vector { var() config float X, Y, Z; }; </uscript>

See Useful Maths Functions for some useful vector assignment operators.

Plane (extends Vector)

A plane definition in 3D space.

<uscript> struct Plane extends Vector { // inherited: normal vector X, Y, Z var() config float W; // distance from origin }; </uscript>

This could also be used to describe a sphere: X, Y, Z is the location of the sphere's center and W is the radius.

Rotator

An orthogonal rotation in 3d space. See Rotator.

<uscript> struct Rotator { var() config int Pitch, Yaw, Roll; }; </uscript>

Coords

An arbitrary coordinate system in 3d space.

<uscript> struct Coords { var() config vector Origin, XAxis, YAxis, ZAxis; }; </uscript>

Scale

A scale and sheering.

<uscript> struct Scale { var() config vector Scale; var() config float SheerRate; var() config enum ESheerAxis { SHEER_None, SHEER_XY, SHEER_XZ, SHEER_YX, SHEER_YZ, SHEER_ZX, SHEER_ZY, } SheerAxis; }; </uscript>

Color

An RGB color.

<uscript> struct Color { var() config byte R, G, B; // red, green, blue color components var() config byte A; // alpha component }; </uscript>

See also the page on custom Color Operators.

Note that many functions and class variables don't use this struct for colours, eg ZoneInfo's ViewFog.

BoundingBox

A bounding box.

<uscript> struct BoundingBox { var vector Min, Max; var byte IsValid; }; </uscript>

BoundingVolume

A bounding box sphere together.

<uscript> struct BoundingVolume extends BoundingBox { var plane Sphere; }; </uscript>
