UKismetMathLibrary::LinearColor_Set

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Overwrites a LinearColor variable with the contents of another. This is the Blueprint-friendly equivalent of a direct assignment, since Blueprint cannot assign struct variables directly via the = operator on a reference.

Caveats & Gotchas

• The function mutates InOutColor in-place via UPARAM(ref). In Blueprint this shows as a pass-by-reference pin; forgetting to wire a variable (instead of a literal) will silently do nothing.
• This is a pure copy — it does not perform any color-space conversion. If InColor is in HSV or sRGB space, the stored values will be wrong unless you convert first.

Signature

static UE_INL_API void LinearColor_Set(UPARAM(ref) FLinearColor& InOutColor, FLinearColor InColor)

Parameters

Name	Type	Description	Default
InOutColor	FLinearColor&	The color variable to overwrite in-place.	—
InColor	FLinearColor	The source color whose values are copied into InOutColor.	—

Return Type

void

Example

Copy one LinearColor into another C++

FLinearColor Target = FLinearColor::White;
FLinearColor Source = FLinearColor(0.2f, 0.8f, 0.4f, 1.0f);
UKismetMathLibrary::LinearColor_Set(Target, Source);
// Target is now (0.2, 0.8, 0.4, 1.0)
