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. |
| FieldNotify | Generate a field entry for the NotifyFieldValueChanged interface. |
| 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. |
| ForceAsFunction | [FunctionMetadata] Indicates that the function should appear as blueprint function even if it doesn't return a value. |
| IgnoreTypePromotion | [FunctionMetadata] Indicates that the function should be ignored when considered for blueprint type promotion |
