UBlueprintMapLibrary::Map_Remove

function Engine Blueprint Since unknown

#include "Kismet/BlueprintMapLibrary.h"

Access: public Specifiers: staticBlueprintCallableCustomThunk

Description

Removes the entry for the given key from a map, if present, and reports whether anything was removed.

Caveats & Gotchas

• Like Map_Add, the int32 types in this signature are wildcard placeholders resolved at runtime via CustomThunk — the declared signature does not reflect the actual key/value types used in a given Blueprint graph.
• Returns false without error if the key wasn't present, so it's safe to call speculatively without checking Map_Contains first.

Signature

static bool Map_Remove(const TMap<int32, int32>& TargetMap, const int32& Key);

Parameters

Name	Type	Description	Default
TargetMap	const TMap<int32, int32>&	The map to remove the key and its associated value from. Wildcard placeholder, mutated in place.	—
Key	const int32&	Wildcard key to remove.	—

Return Type

bool

Example

Remove an entry and check the result C++

TMap<FName, int32> Scores;
Scores.Add(TEXT("Player1"), 100);
const bool bRemoved = Scores.Remove(TEXT("Player1")) > 0; // native TMap::Remove — the direct C++ equivalent of the Map_Remove Blueprint node
