what is this Metadata Specifiers??

I begin C++ in unreal 4 not very long

so i can’t find this Metadata Specifiers…
UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Movement, meta = (AllowPrivateAccess = “true”))

AllowPrivateAccess ← this metadata is problem…

where this metadata declare is???
plz help…

hey dude,

so i dont see this specifier within Metadata Specifiers | Unreal Engine Documentation.

What you eventually dont know is that, Blueprints are “kind-of” childclasses of your C++ class. So access modifier working the same as usual.

public -> Accessable in BLueprint
protected -> Accessable in BP
private -> NOT Accessable in BP

so if you want to use private member within a blueprint you can use this meta specifier.

best regards
