function
UKismetMathLibrary::RandomBool Engine

Returns a uniformly distributed random boolean — roughly 50/50 true or false on each call.

function
UKismetMathLibrary::RandomBoolWithWeight Engine

Returns true with the given probability and false otherwise.

function
UKismetMathLibrary::RandomBoolWithWeightFromStream Engine

Returns true with the given probability using a caller-supplied FRandomStream instead of the global RNG.

function
UKismetMathLibrary::RandomFloat Engine

Returns a random float in the range [0, 1] using the global random stream.

function
UKismetMathLibrary::RandomFloatInRange Engine

Returns a random float uniformly distributed between Min and Max.

function
UKismetMathLibrary::RandomInteger Engine

Returns a uniformly distributed random integer in the range [0, Max - 1].

function
UKismetMathLibrary::RandomInteger64 Engine

Returns a uniformly distributed random int64 in the range [0, Max).

function
UKismetMathLibrary::RandomInteger64InRange Engine

Returns a uniformly distributed random int64 between Min and Max, inclusive on both ends.

function
UKismetMathLibrary::RandomIntegerInRange Engine

Returns a random integer in the inclusive range [Min, Max].

function
UKismetMathLibrary::RandomPointInBoundingBox Engine

Returns a uniformly random point inside an axis-aligned bounding box defined by a center and per-axis half-extents.

function
UKismetMathLibrary::RandomPointInBoundingBox_Box Engine

Returns a uniformly random point inside an FBox.

function
UKismetMathLibrary::RandomRotator Engine

Generates a uniformly random rotation in Pitch [-90, 90] and Yaw [-180, 180].

function
UKismetMathLibrary::RandomUnitVector Engine

Returns a random unit vector (length 1) uniformly distributed over the surface of a sphere.

function
UKismetMathLibrary::RandomUnitVectorInConeInDegrees Engine

Convenience wrapper around RandomUnitVectorInConeInRadians that accepts degrees.

function
UKismetMathLibrary::RandomUnitVectorInConeInRadians Engine

Returns a random unit vector within a symmetric cone around ConeDir, with uniform distribution on the sphere surface inside the cone.

function
UKismetMathLibrary::RandomUnitVectorInEllipticalConeInDegrees Engine

Degree-unit wrapper around RandomUnitVectorInEllipticalConeInRadians.

function
UKismetMathLibrary::RandomUnitVectorInEllipticalConeInRadians Engine

Returns a random unit vector inside an elliptical cone around ConeDir with independently controlled horizontal (yaw) and vertical (pitch) half-angles.

function
UKismetMathLibrary::BreakRandomStream Engine

Extracts the initial seed value from an FRandomStream.

function
UNavigationSystemV1::GetRandomReachablePointInRadius NavigationSystem

Returns a random NavMesh point that is reachable from Origin within the given radius.

function
UKismetMathLibrary::LinearColor_SetRandomHue Engine

Chooses a random hue and writes a visually pleasing fully-saturated color into the target LinearColor.

function
UKismetMathLibrary::MakeRandomStream Engine

Creates an FRandomStream initialized with a specific seed.

function
UKismetMathLibrary::MakeRandomStreamFromLocation Engine

Creates a deterministic FRandomStream whose seed is derived from a world-space location, optionally quantized to a grid.

struct
FMath Core

The primary math utility struct in Unreal Engine, providing static functions for arithmetic, interpolation, trigonometry, random number generation, and geometric operations.

function
FMath::RandRange Core

Returns a random integer in the inclusive range [Min, Max].

function
AActor::ResetPropertiesForConstruction Engine

Resets private actor properties to their defaults and re-seeds all FRandomStream members, so they will replay their random sequence from the beginning on the next construction.

class
TArray Core

The primary dynamic array container in Unreal Engine, equivalent to `std::vector`.

class
UKismetMathLibrary Engine

Blueprint function library providing a comprehensive set of math utilities: boolean logic, byte/int/float arithmetic, vector and rotator operations, interpolation, random number generation, and matrix math.

class
USoundCue Engine

A graph-based audio asset that combines SoundWaves with nodes for mixing, randomization, looping, pitch modulation, and sequencing.
