UE Gameplay Tags and Messaging
Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".
Gameplay Tags are a built-in runtime module, not a plugin: add "GameplayTags" to PublicDependencyModuleNames in your Build.cs and include GameplayTagContainer.h / NativeGameplayTags.h / GameplayTagsManager.h. This skill owns tag definition (native and ini), FGameplayTag, FGameplayTagContainer, FGameplayTagQuery, UGameplayTagsManager, editor filtering, and decoupled gameplay messaging — including the AsyncMessageSystem plugin (Experimental in 5.8).
Context
Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.
Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.
| Request is about… | Go to |
|---|---|
| Declaring tags in C++, native tag macros, module setup | Native Tag Definitions |
Declaring tags in .ini, data tables, renaming a tag | Ini and Data Table Tag Sources |
| Testing a tag, container membership, parent vs exact | Matching Semantics |
| Multi-tag conditions, AND/OR/NOT, designer-authored rules | Tag Queries |
| Actors exposing tags, gates and states built from tags | Tag-Driven Design |
| Sending tags over the network, tag cost, hot paths | Replication and Performance |
| Broadcasting events between systems without hard references | Decoupled Messaging |
Tag pickers, Categories filtering, per-team tag files | Editor UX and Filtering |
Tag Sources
A tag must be registered before it can be requested. Four sources feed the one global dictionary held by UGameplayTagsManager:
| Source | Where | Use for |
|---|---|---|
| Native | UE_DEFINE_GAMEPLAY_TAG* in a module .cpp | Tags C++ compares against by name |
| Default ini | Config/DefaultGameplayTags.ini, +GameplayTagList= | Tags authored by designers |
| Extra ini | Config/Tags/*.ini and plugin config dirs | Per-team or per-plugin tag lists |
| Data table | UDataTable of FGameplayTagTableRow listed in GameplayTagTableList | Bulk import from a spreadsheet |
EGameplayTagSourceType (Native, DefaultTagList, TagList, RestrictedTagList, DataTable, Invalid) names these in the editor. Tags are hierarchical: registering MyGame.State.Stunned implicitly registers MyGame.State and MyGame.
Native Tag Definitions
Declare in a public header, define in exactly one .cpp of the same module. The macros static_assert that they are used from a .cpp.
// MyGameplayTags.h
#pragma once
#include "NativeGameplayTags.h"
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_State_Stunned);
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_Damage_Fire);
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_Message_ScoreChanged);
// MyGameplayTags.cpp
#include "MyGameplayTags.h"
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_State_Stunned, "MyGame.State.Stunned", "Character cannot act");
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_Damage_Fire, "MyGame.Damage.Fire", "Fire damage channel");
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_Message_ScoreChanged, "MyGame.Message.ScoreChanged", "Score changed broadcast");
| Macro | Parameters | Effect |
|---|---|---|
UE_DECLARE_GAMEPLAY_TAG_EXTERN | (TagName) | extern FNativeGameplayTag TagName; — goes in the header, prefixed with your _API macro |
UE_DEFINE_GAMEPLAY_TAG | (TagName, Tag) | Defines the variable with an empty dev comment |
UE_DEFINE_GAMEPLAY_TAG_COMMENT | (TagName, Tag, Comment) | Same plus a developer comment shown in the editor |
UE_DEFINE_GAMEPLAY_TAG_STATIC | (TagName, Tag) | static — visible only inside that one .cpp, with no matching declaration in a header |
Tag and Comment are bare string literals: the macro wraps Comment in TEXT() itself. Writing TEXT("…") there does not compile.
FNativeGameplayTag registers on static construction and unregisters when the module unloads, so tags from a plugin disappear cleanly with the plugin. It converts implicitly to FGameplayTag and also exposes GetTag():
const FGameplayTag Stunned = TAG_MyGame_State_Stunned.GetTag();
if (OwnedTags.HasTag(TAG_MyGame_State_Stunned))
{
return;
}
One definition rule: exactly one UE_DEFINE_GAMEPLAY_TAG (or _COMMENT / _STATIC) per tag variable per binary. Two modules defining the same tag string is fine (the manager reference-counts registrations), but two definitions of the same variable is a link error, and a definition in a header breaks every translation unit that includes it.
To register a tag whose name is only known at runtime, call the manager directly:
const FGameplayTag Runtime = UGameplayTagsManager::Get().AddNativeGameplayTag(
FName(TEXT("MyGame.Generated.Slot01")), TEXT("Generated at startup"));
AddNativeGameplayTag after startup invalidates fast replication (see Replication and Performance). Register from CallOrRegister_OnAddNativeTagsDelegate, and run code that consumes tags from CallOrRegister_OnDoneAddingNativeTagsDelegate:
// MyGameModule.cpp — FDelegateHandle NativeTagsHandle; is a member of FMyGameModule.
#include "MyGameModule.h"
#include "GameplayTagsManager.h"
void FMyGameModule::StartupModule()
{
NativeTagsHandle = UGameplayTagsManager::CallOrRegister_OnDoneAddingNativeTagsDelegate(
FSimpleMulticastDelegate::FDelegate::CreateRaw(this, &FMyGameModule::OnTagsReady));
}
void FMyGameModule::ShutdownModule()
{
UGameplayTagsManager::UnregisterNativeTagDelegate(NativeTagsHandle);
}
If registration already finished, CallOrRegister_OnDoneAddingNativeTagsDelegate runs the delegate immediately and CallOrRegister_OnAddNativeTagsDelegate runs it at the end of the current module load (GameplayTagsManager.h:419-427), so there is no ordering hazard in calling them late.
Ini and Data Table Tag Sources
UGameplayTagsSettings is UCLASS(config=GameplayTags, defaultconfig) deriving from UGameplayTagsList, so Project Settings → Gameplay Tags writes Config/DefaultGameplayTags.ini:
[/Script/GameplayTags.GameplayTagsSettings]
ImportTagsFromConfig=True
FastReplication=False
NumBitsForContainerSize=6
NetIndexFirstBitSegment=16
+GameplayTagList=(Tag="MyGame.State.Stunned",DevComment="Character cannot act")
+GameplayTagList=(Tag="MyGame.Damage.Fire",DevComment="Fire damage channel")
+GameplayTagTableList=/Game/Data/DT_MyGameTags.DT_MyGameTags
+GameplayTagRedirects=(OldTagName="MyGame.State.Stun",NewTagName="MyGame.State.Stunned")
| Key | Type | Meaning |
|---|---|---|
ImportTagsFromConfig | bool | Master switch for ini-defined tags; read back through UGameplayTagsManager::ShouldImportTagsFromINI() |
GameplayTagList | TArray<FGameplayTagTableRow> | Tag (FName) plus DevComment (FString) |
GameplayTagTableList | TArray<FSoftObjectPath> | Data tables of FGameplayTagTableRow, loaded by LoadGameplayTagTables |
GameplayTagRedirects | TArray<FGameplayTagRedirect> | OldTagName → NewTagName; inherited from UGameplayTagsList |
CategoryRemapping | TArray<FGameplayTagCategoryRemap> | Remaps an engine Categories filter onto project categories |
RestrictedConfigFiles | TArray<FRestrictedConfigInfo> | Top-level tags only a named owner may edit |
InvalidTagCharacters | FString | Characters rejected in tag names, beyond newline and friends |
Extra ini sources live in Config/Tags/ (added automatically) and in any directory passed to UGameplayTagsManager::Get().AddTagIniSearchPath(RootDir); RemoveTagIniSearchPath takes them away again. A Game Feature plugin's config directory is registered this way, which is why its tags appear only while the plugin is active.
Renaming a tag requires a redirect. FGameplayTagRedirect is { OldTagName, NewTagName }; FGameplayTagRedirectors::Get().RedirectTag(OldName, OutTag) is what serialization uses (engine-internal: the class is not exported). Without a redirect, every asset that referenced the old name silently loads an invalid tag.
Full ini and data-table details are in gameplay-tag-reference.md.
Matching Semantics
FGameplayTag is one FName. A container keeps the explicitly added tags plus a transient expanded parent list, so parent-aware checks are array lookups, not string parsing.
| Call | Receiver | Semantics | {"A.1"} vs A |
|---|---|---|---|
MatchesTag(TagToCheck) | FGameplayTag | This tag or any parent equals TagToCheck | A.1.MatchesTag(A) → true; A.MatchesTag(A.1) → false |
MatchesTagExact(TagToCheck) | FGameplayTag | Names equal | A.1.MatchesTagExact(A) → false |
MatchesAny(ContainerToCheck) | FGameplayTag | Parent-expanded match against any tag in the container | A.1.MatchesAny({A,B}) → true |
MatchesAnyExact(ContainerToCheck) | FGameplayTag | Container explicitly holds this tag | A.1.MatchesAnyExact({A,B}) → false |
HasTag(TagToCheck) | FGameplayTagContainer | Explicit or parent list contains it | {A.1}.HasTag(A) → true |
HasTagExact(TagToCheck) | FGameplayTagContainer | Explicit list only | {A.1}.HasTagExact(A) → false |
HasAny / HasAnyExact | FGameplayTagContainer | At least one; false for an empty argument | {A.1}.HasAny({A,B}) → true |
HasAll / HasAllExact | FGameplayTagContainer | All; true for an empty argument | {A.1,B.1}.HasAll({A,B}) → true |
Filter(OtherContainer) | FGameplayTagContainer | New container of tags matching any tag in OtherContainer, parents expanded | {A.1,C}.Filter({A}) → {A.1} |
FilterExact(OtherContainer) | FGameplayTagContainer | True intersection, exact names | {A.1,C}.FilterExact({A}) → {} |
The empty-argument asymmetry is deliberate: "any of nothing" is false, "all of nothing" is true. Gates written as RequiredTags.IsEmpty() || Owned.HasAll(RequiredTags) are redundant.
FGameplayTagContainer MakeStateTags(const FGameplayTagContainer& ExtraTags)
{
FGameplayTagContainer Owned;
Owned.AddTag(TAG_MyGame_State_Stunned); // checks uniqueness and refills parents
Owned.AddTagFast(TAG_MyGame_Damage_Fire); // no uniqueness check — only when the tag is known to be new
Owned.AppendTags(ExtraTags);
Owned.RemoveTag(TAG_MyGame_State_Stunned);
if (!Owned.IsEmpty())
{
UE_LOG(LogMyGame, Log, TEXT("%d tags, first %s, last %s: %s"),

## Tag Sources
A tag must be registered before it can be requested. Four sources feed the one global dictionary held by `UGameplayTagsManager`:
| Source | Where | Use for |
|---|---|---|
| Native | `UE_DEFINE_GAMEPLAY_TAG*` in a module `.cpp` | Tags C++ compares against by name |
| Default ini | `Config/DefaultGameplayTags.ini`, `+GameplayTagList=` | Tags authored by designers |
| Extra ini | `Config/Tags/*.ini` and plugin config dirs | Per-team or per-plugin tag lists |
| Data table | `UDataTable` of `FGameplayTagTableRow` listed in `GameplayTagTableList` | Bulk import from a spreadsheet |
`EGameplayTagSourceType` (`Native`, `DefaultTagList`, `TagList`, `RestrictedTagList`, `DataTable`, `Invalid`) names these in the editor. Tags are hierarchical: registering `MyGame.State.Stunned` implicitly registers `MyGame.State` and `MyGame`.
## Native Tag Definitions
Declare in a public header, define in exactly one `.cpp` of the same module. The macros `static_assert` that they are used from a `.cpp`.
```cpp
// MyGameplayTags.h
#pragma once
#include "NativeGameplayTags.h"
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_State_Stunned);
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_Damage_Fire);
MYGAME_API UE_DECLARE_GAMEPLAY_TAG_EXTERN(TAG_MyGame_Message_ScoreChanged);
```
```cpp
// MyGameplayTags.cpp
#include "MyGameplayTags.h"
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_State_Stunned, "MyGame.State.Stunned", "Character cannot act");
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_Damage_Fire, "MyGame.Damage.Fire", "Fire damage channel");
UE_DEFINE_GAMEPLAY_TAG_COMMENT(TAG_MyGame_Message_ScoreChanged, "MyGame.Message.ScoreChanged", "Score changed broadcast");
```
| Macro | Parameters | Effect |
|---|---|---|
| `UE_DECLARE_GAMEPLAY_TAG_EXTERN` | `(TagName)` | `extern FNativeGameplayTag TagName;` — goes in the header, prefixed with your `_API` macro |
| `UE_DEFINE_GAMEPLAY_TAG` | `(TagName, Tag)` | Defines the variable with an empty dev comment |
| `UE_DEFINE_GAMEPLAY_TAG_COMMENT` | `(TagName, Tag, Comment)` | Same plus a developer comment shown in the editor |
| `UE_DEFINE_GAMEPLAY_TAG_STATIC` | `(TagName, Tag)` | `static` — visible only inside that one `.cpp`, with no matching declaration in a header |
`Tag` and `Comment` are bare string literals: the macro wraps `Comment` in `TEXT()` itself. Writing `TEXT("…")` there does not compile.
`FNativeGameplayTag` registers on static construction and unregisters when the module unloads, so tags from a plugin disappear cleanly with the plugin. It converts implicitly to `FGameplayTag` and also exposes `GetTag()`:
```cpp
const FGameplayTag Stunned = TAG_MyGame_State_Stunned.GetTag();
if (OwnedTags.HasTag(TAG_MyGame_State_Stunned))
{
return;
}
```
**One definition rule:** exactly one `UE_DEFINE_GAMEPLAY_TAG` (or `_COMMENT` / `_STATIC`) per tag variable per binary. Two modules defining the same tag string is fine (the manager reference-counts registrations), but two definitions of the same *variable* is a link error, and a definition in a header breaks every translation unit that includes it.
To register a tag whose name is only known at runtime, call the manager directly:
```cpp
const FGameplayTag Runtime = UGameplayTagsManager::Get().AddNativeGameplayTag(
FName(TEXT("MyGame.Generated.Slot01")), TEXT("Generated at startup"));
```
`AddNativeGameplayTag` after startup invalidates fast replication (see [Replication and Performance](#replication-and-performance)). Register from `CallOrRegister_OnAddNativeTagsDelegate`, and run code that *consumes* tags from `CallOrRegister_OnDoneAddingNativeTagsDelegate`:
```cpp
// MyGameModule.cpp — FDelegateHandle NativeTagsHandle; is a member of FMyGameModule.
#include "MyGameModule.h"
#include "GameplayTagsManager.h"
void FMyGameModule::StartupModule()
{
NativeTagsHandle = UGameplayTagsManager::CallOrRegister_OnDoneAddingNativeTagsDelegate(
FSimpleMulticastDelegate::FDelegate::CreateRaw(this, &FMyGameModule::OnTagsReady));
}
void FMyGameModule::ShutdownModule()
{
UGameplayTagsManager::UnregisterNativeTagDelegate(NativeTagsHandle);
}
```
If registration already finished, `CallOrRegister_OnDoneAddingNativeTagsDelegate` runs the delegate immediately and `CallOrRegister_OnAddNativeTagsDelegate` runs it at the end of the current module load (`GameplayTagsManager.h:419-427`), so there is no ordering hazard in calling them late.
## Ini and Data Table Tag Sources
`UGameplayTagsSettings` is `UCLASS(config=GameplayTags, defaultconfig)` deriving from `UGameplayTagsList`, so Project Settings → Gameplay Tags writes `Config/DefaultGameplayTags.ini`:
```ini
[/Script/GameplayTags.GameplayTagsSettings]
ImportTagsFromConfig=True
FastReplication=False
NumBitsForContainerSize=6
NetIndexFirstBitSegment=16
+GameplayTagList=(Tag="MyGame.State.Stunned",DevComment="Character cannot act")
+GameplayTagList=(Tag="MyGame.Damage.Fire",DevComment="Fire damage channel")
+GameplayTagTableList=/Game/Data/DT_MyGameTags.DT_MyGameTags
+GameplayTagRedirects=(OldTagName="MyGame.State.Stun",NewTagName="MyGame.State.Stunned")
```
| Key | Type | Meaning |
|---|---|---|
| `ImportTagsFromConfig` | `bool` | Master switch for ini-defined tags; read back through `UGameplayTagsManager::ShouldImportTagsFromINI()` |
| `GameplayTagList` | `TArray<FGameplayTagTableRow>` | `Tag` (`FName`) plus `DevComment` (`FString`) |
| `GameplayTagTableList` | `TArray<FSoftObjectPath>` | Data tables of `FGameplayTagTableRow`, loaded by `LoadGameplayTagTables` |
| `GameplayTagRedirects` | `TArray<FGameplayTagRedirect>` | `OldTagName` → `NewTagName`; inherited from `UGameplayTagsList` |
| `CategoryRemapping` | `TArray<FGameplayTagCategoryRemap>` | Remaps an engine `Categories` filter onto project categories |
| `RestrictedConfigFiles` | `TArray<FRestrictedConfigInfo>` | Top-level tags only a named owner may edit |
| `InvalidTagCharacters` | `FString` | Characters rejected in tag names, beyond newline and friends |
Extra ini sources live in `Config/Tags/` (added automatically) and in any directory passed to `UGameplayTagsManager::Get().AddTagIniSearchPath(RootDir)`; `RemoveTagIniSearchPath` takes them away again. A Game Feature plugin's config directory is registered this way, which is why its tags appear only while the plugin is active.
