UKismetMathLibrary::Conv_BoolToByte

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPureBlueprintAutocast

Description

Converts a boolean to a byte (uint8): false returns 0, true returns 1.

• Returns only 0 or 1 — never any other byte value. If you need a full range mapping from bool to a custom byte enum value, use a Select node or ternary expression instead.
• Storing bools as bytes in replicated structs can save bandwidth when a UPROPERTY bitfield isn't available, but be aware that Blueprint byte pins display as enum selectors when bound to a UENUM, which can cause unexpected display issues if the byte is later used as an enum.
