UKismetMathLibrary::Conv_IntToBool

function Engine Blueprint Since 4.0
#include "Kismet/KismetMathLibrary.h"
Access: public Specifiers: staticBlueprintPureBlueprintAutocast

Description

Converts an integer to a boolean: 0 maps to false, any other value maps to true.

Caveats & Gotchas

  • Any non-zero value — including negative numbers — returns true. This mirrors C++ implicit bool conversion, but can produce unexpected results if you assumed only 1 means true (e.g. bitmask fields where multiple bits are set).
  • As a BlueprintAutocast this fires silently when an Integer pin is connected to a Boolean pin. Consider whether a comparison node (== 0, != 0) is more readable and self-documenting in Blueprint graphs.
