UKismetStringLibrary::Conv_PlatformUserIdToString

function Engine Blueprint Since unknown

#include "Kismet/KismetStringLibrary.h"

Access: public Specifiers: staticBlueprintPureBlueprintAutocast

Description

Converts a platform user ID to its string representation, showing the underlying integer handle. Useful for logging which local user or gamepad slot triggered an event.

Caveats & Gotchas

• The output is just the raw internal integer (via GetInternalId()), not a stable cross-platform account identifier — it has no meaning outside debug logging.
• FPlatformUserId values can be reassigned as controllers connect and disconnect, so the string is only valid for the current session.
