UKismetSystemLibrary::ParseParamValue

function Engine Blueprint Since unknown

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns true and fills OutValue if '-option=value' is present in InString for the given InParam.

Caveats & Gotchas

• Returns false and leaves OutValue unchanged if the switch is present without a value (bare -option) — check ParseParam separately if you need to distinguish 'absent' from 'present but no value'.
• Values are not unquoted or unescaped; if the original command line quoted the value, the quotes are part of OutValue.
