UBlueprintMapLibrary::SetMapPropertyByName

function Engine Blueprint Since unknown

#include "Kismet/BlueprintMapLibrary.h"

Access: public Specifiers: staticBlueprintCallableCustomThunk

Description

Internal helper that assigns a wildcard map value to a named TMap UPROPERTY on an object, used to back the auto-generated Blueprint setter node for exposed map properties.

Caveats & Gotchas

• Marked BlueprintInternalUseOnly in its UFUNCTION meta, so it never appears in the Blueprint node search — the editor wires it in automatically when you drag off a 'Set' pin for a map property.
• Not intended to be called from C++; assign to the UObject's TMap property directly instead of going through this reflection-based helper.

Signature

static void SetMapPropertyByName(UObject* Object, FName PropertyName, const TMap<int32, int32>& Value);

Parameters

Name	Type	Description	Default
Object	UObject*	The object whose property will be set.	—

Return Type

Example

Native equivalent C++

// Blueprint uses SetMapPropertyByName internally for the auto-generated setter node.
// In C++, assign the property directly instead:
MyObject->ScoresProperty = NewScores;
