FBlueprintMetadata

Struct/Enum/Class: If true, this class, struct, or enum is a valid type for use as a variable in a blueprint

Metadata that should be used with UPARAM to specify whether a TSubclassOf argument allows abstract classes

If true, properties defined in the C++ private scope will be accessible to blueprints

Stub function used internally by animation blueprints

If true, an unconnected pin will generate a UPROPERTY under the hood to connect as the input, which will be set to the literal value for the pin.

Metadata that identifies an enum as a set of explicitly-named bitflags.

Metadata that identifies an integral property as a bitmask.

Metadata that associates a bitmask property with a bitflag enum.

Class: [ClassMetadata] If present, the component class can be spawned by a blueprint

For functions that have the MD_WorldContext metadata but are safe to be called from contexts that do not have the ability to provide the world context (either through GetWorld() or ShowWorldContextPin class metadata

Metadata string that indicates the specified event can be triggered in editor

[InterfaceMetadata]

[ClassMetadata] Used for Actor and Component classes. If the native class cannot tick, Blueprint generated classes based this Actor or Component can never tick even if bCanBlueprintsTickByDefault is true.

[ClassMetadata] Used for Actor and Component classes. If the native class cannot tick, Blueprint generated classes based this Actor or Component can have bCanEverTick flag overridden even if bCanBlueprintsTickByDefault is false.

[FunctionMetadata] Indicates that the function should be drawn as a compact node with the specified body title

Indicates that the UFUNCTION implements its own thunk function

Specifies which struct implements the custom thunk functions for this class

Metadata to identify an DataTable Pin.

If true, the specified UObject parameter will default to "self" if nothing is connected

[FunctionMetadata] Indicates that the function is deprecated

[FunctionMetadata] Supplies the custom message to use for deprecation

For functions that should be compiled in development mode only

[FunctionMetadata] Indicates that the function should be drawn with this title over the function name

Metadata that flags the function output param that will be controlled by the "MD_DynamicOutputType" pin

Metadata that flags function params that govern what type of object the function returns

Synonym for MD_ExpandEnumAsExecs

Indicates that during compile we want to create multiple exec pins from an enum param

Categories of functions to expose on this property

UPROPERTY will be exposed on "Spawn Blueprint" nodes as an input

The category that a function appears under in the palette.

Keywords used when searching for functions

Comma delimited list of pins that should be hidden on this function.

If true, the self pin should not be shown or connectable regardless of purity, const, etc.

[ClassMetadata] Used to make the first subclass of a class ignore all inherited showCategories and hideCategories commands

[FunctionMetadata] Indicates that a particular function parameter is for internal use only, which means it will be both hidden and not connectible.

If true, the class will be usable as a base for blueprints

Marks a UFUNCTION as latent execution

Metadata that flags TMap function parameters that will have their type determined at blueprint compile time

Metadata string that indicates to use the MaterialParameterCollectionFunction node.

Metadata that flags make/break functions for specific struct types.

If true, this class, struct, or enum is not valid for use as a variable in a blueprint.

UPROPERTY cannot be modified by other blueprints

UPROPERTY uses the specified function as a getter rather than reading from the property directly

UPROPERTY uses the specified function as a setter rather than writing to the property directly

Function metadata

A listing of classes that this class is accessible from (and only those classes, if present).

[FunctionMetadata] Indicates the display name of the return value pin

Metadata that flags TSet parameters that will have their type determined at blueprint compile time

If true, the hidden world context pin will be visible when the function is placed in a child blueprint of the class.

Metadata string that sets the tooltip

Marks a UFUNCTION as unsafe for use in the UCS, which prevents it from being called from the UCS.

Metadata that signals to the editor that enum values correspond to mask values instead of bitshift (index) values.

Marks a UFUNCTION as accepting variadic arguments

The specified parameter should be used as the context object when retrieving a UWorld pointer (implies hidden and default-to-self)
