UKismetMathLibrary::DegSin

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the sine of A where A is in degrees. Handles the degree-to-radian conversion internally, making it safer than calling Sin directly with degree values.

Caveats & Gotchas

• Slightly slower than Sin(DegreesToRadians(A)) due to the internal conversion, but negligible outside of tight inner loops — the real benefit is eliminating the common forgotten-conversion bug.
• Blueprint surfaces this as 'Sin (Degrees)' with the compact node title 'SINd' — easy to confuse with the plain 'Sin' node which expects radians.

Signature

static UE_INL_API double DegSin(double A);

Parameters

A	double	Angle in degrees.	—

Return Type

double

Example

Oscillate an actor vertically using a degree-based angle C++

// OscillationAngle advances in degrees each tick
OscillationAngle += 90.0 * DeltaTime;
float ZOffset = (float)(Amplitude * UKismetMathLibrary::DegSin(OscillationAngle));
SetActorLocation(BaseLocation + FVector(0, 0, ZOffset));
