UBlueprintMapLibrary::Map_Clear
#include "Kismet/BlueprintMapLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Clears a map of all entries, resetting it to empty.
Caveats & Gotchas
- • Mutates TargetMap in place — there is no separate output pin; the same map instance you pass in ends up empty after the call.
- • In C++, call TMap::Empty() directly instead of routing through this wildcard node.
