Values

Name	Description
BlueprintImplementableEvent	This function is designed to be overridden by a blueprint.
BlueprintNativeEvent	This function is designed to be overridden by a blueprint, but also has a native implementation.
SealedEvent	This function is sealed and cannot be overridden in subclasses.
Exec	This function is executable from the command line.
Server	This function is replicated, and executed on servers.
Client	This function is replicated, and executed on clients.
NetMulticast	This function is both executed locally on the server and replicated to all clients, regardless of the Actor's NetOwner.
Reliable	Replication of calls to this function should be done on a reliable channel.
Unreliable	Replication of calls to this function can be done on an unreliable channel.
BlueprintPure	This function fulfills a contract of producing no side effects, and additionally implies BlueprintCallable.
BlueprintCallable	This function can be called from blueprint code and should be exposed to the user of blueprint editing tools.
BlueprintGetter	This function is used as the get accessor for a blueprint exposed property. Implies BlueprintPure and BlueprintCallable.
BlueprintSetter	This function is used as the set accessor for a blueprint exposed property. Implies BlueprintCallable.
BlueprintAuthorityOnly	This function will not execute from blueprint code if running on something without network authority.
BlueprintCosmetic	This function is cosmetic and will not run on dedicated servers.
BlueprintInternalUseOnly	Indicates that a Blueprint exposed function should not be exposed to the end user.
CallInEditor	This function can be called in the editor on selected instances via a button in the details panel.
CustomThunk	The UnrealHeaderTool code generator will not produce a execFoo thunk for this function; it is up to the user to provide one.
Category	Specifies the category of the function when displayed in blueprint editing tools.
WithValidation	This function must supply a _Validate implementation.
ServiceRequest	This function is RPC service request.
ServiceResponse	This function is RPC service response.
Variadic	[FunctionMetadata] Marks a UFUNCTION as accepting variadic arguments.
ReturnDisplayName	[FunctionMetadata] Indicates the display name of the return value pin
InternalUseParam	[FunctionMetadata] Indicates that a particular function parameter is for internal use only, which means it will be both hidden and not connectible.
