UKismetStringLibrary::Conv_StringToVector3f

function Engine Blueprint Since unknown

#include "Kismet/KismetStringLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Parses a string in the 'X= Y= Z=' format back into a single-precision FVector3f, reporting whether parsing succeeded via OutIsValid.

Caveats & Gotchas

• FVector3f is single-precision — this exists for interoperability with float-based APIs (e.g. some physics and rendering code) rather than general Blueprint math, which typically uses the double-precision FVector overload instead.
• Like Conv_StringToVector, OutIsValid comes from FVector3f::InitFromString and doesn't guarantee OutConvertedVector is zeroed on failure.

Signature

static void Conv_StringToVector3f(const FString& InString, FVector3f& OutConvertedVector, bool& OutIsValid)

Parameters

Name	Type	Description	Default
InString	const FString&	The string to parse, expected in the 'X= Y= Z=' format.	—
OutConvertedVector	FVector3f&	The parsed single-precision vector value; only meaningful when OutIsValid is true.	—
OutIsValid	bool&	True if InString was successfully parsed into a vector.	—

Return Type

void

Example

Parse a float vector for a physics API C++

FString VectorText = TEXT("X=1.000 Y=0.000 Z=0.000");
FVector3f Direction;
bool bIsValid = false;
UKismetStringLibrary::Conv_StringToVector3f(VectorText, Direction, bIsValid);
