+name: C# Chat System Formatting
+description: Hướng dẫn viết code C# cho hệ thống chat dùng AUIDialog.FormatPrintf và pGameUI.GetStringFromTable.
+---
+
+# C# Chat System Formatting
+
+Skill này cung cấp hướng dẫn khi viết code C# cho hệ thống chat (ví dụ như khi chuyển đổi code từ C++ sang C# trong Unity).
+
+## Quy tắc lấy chuỗi và format
+
+Khi cần lấy một chuỗi từ bảng ngôn ngữ (Table) và format chuỗi đó với các tham số (thay thế cho %s, %d,...), hãy sử dụng kết hợp `pGameUI.GetStringFromTable` và `AUIDialog.FormatPrintf`.
+
+Trong phiên bản C++ gốc (ví dụ trong `EC_GameUIMan.cpp`), việc lấy chuỗi thường dùng `GetStringFromTable` và format bằng `swprintf` hoặc các hàm tương tự. Ở phiên bản C#, chúng ta thực hiện như sau:
+
+```csharp
+// Ví dụ Table 9343: chuỗi dạng "Thời gian đăng nhập trước: %s"
+// AUIDialog.FormatPrintf sẽ thực hiện kết hợp giữa pGameUI.GetStringFromTable(9343) và chuỗi timeStr
+string textTime = AUIDialog.FormatPrintf(pGameUI.GetStringFromTable(9343), timeStr);
+```
+
+## Các bước thực hiện
+1. Đảm bảo đã lấy được referent tới `pGameUI`, ví dụ qua `CECUIManager.Instance?.GetInGameUIMan()`.
+2. Lấy chuỗi format gốc từ bảng ngôn ngữ: `pGameUI.GetStringFromTable(ID)`.
+3. Dùng `AUIDialog.FormatPrintf` để thay thế các placeholder (như `%s`, `%d`) trong chuỗi lấy được bằng các giá trị thực tế.
+4. Gửi chuỗi đã được format đến hệ thống chat, ví dụ qua `EventBus.Publish(new GameSession.ChatMessageEvent {...})`.

+If the string from the table uses C++ format specifiers (`%d`, `%s`, `%f`), `AUIDialog.FormatPrintf` handles them natively without requiring string conversion.
+```csharp
+string confirmMessage = AUIDialog.FormatPrintf(GetStringFromTable(11326), needMoney, needSp);

 ```csharp
 string confirmMessage = string.Format(GetStringFromTable(11326), needMoney, needSp);

 **Notes**:
- C++'s `ACString::Format()` is a member function
- C#'s `string.Format()` is a static function
- Both use the same placeholder syntax: `%d` (C++) or `{0}`, `{1}` (C#)
- If your string table uses C++ format specifiers, you may need to convert them:
+- C++'s `ACString::Format()` is a member function.
+- C#'s `string.Format()` is a static function but only understands `{0}`, `{1}` syntax.
+- If your string table still uses C++ format specifiers (`%d`, `%s`, `%f`), **you should use `AUIDialog.FormatPrintf`**. Otherwise, you would need to manually convert the placeholders in the string table:
  - `%d` → `{0}`, `{1}` for integers
  - `%s` → `{0}`, `{1}` for strings

+### Example 4: Clickable Text Links (TextMeshPro)
+
+**C++ (Rich Text and Actions)**:
+In C++, player names or interactive elements (like items) in chat are often wrapped with custom delimiters like `&PlayerName&` to be parsed later for coloring and clicking. The click actions are handled by complex UI dialogue components.
+
+**C# (Unity TextMeshPro `<link>` tag)**:
+In Unity's TextMeshPro, we can use the standard `<link>` tag to define an interactive region of text. By parsing the legacy `&PlayerName&` format using Regex, we can inject a `<link>` tag that Unity's event system can interact with.
+
+1. **Format the string with Regex replacing delimiters (e.g., in `EC_GameUIMan.cs`)**:
+```csharp
+if (parsedMsg.Contains("&"))
+{
+    // Convert &PlayerName& into <color=#HexColor><u><link="PlayerName">PlayerName</link></u></color>
+    parsedMsg = System.Text.RegularExpressions.Regex.Replace(
+        parsedMsg,
+        @"&([^&]+)&",
+        $"<color=#{colorHex}><u><link=\"$1\">$1</link></u></color>"
+    );
+}
+```
+
+2. **Handle the Click Event via Unity EventSystems (e.g., in `ChatMessageView.cs`)**:
+The UI View script attached to the TextMeshPro text must implement `IPointerClickHandler` to intercept pointer clicks on the `<link>` markup.
+```csharp
+using UnityEngine.EventSystems;
+using TMPro;
+
+public class ChatMessageView : MonoBehaviour, IPointerClickHandler
+{
+    public EC_UIUtility.TextOutlet messageText;
+
+    public void OnPointerClick(PointerEventData eventData)
+    {
+        if (messageText == null || messageText.tmp == null) return;
+
+        // Check if the pointer click intersects with any <link> tag boundary
+        int linkIndex = TMP_TextUtilities.FindIntersectingLink(messageText.tmp, eventData.position, eventData.pressEventCamera);
+        if (linkIndex != -1)
+        {
+            // Retrieve the link ID (which we dynamically set to the player's name)
+            TMP_LinkInfo linkInfo = messageText.tmp.textInfo.linkInfo[linkIndex];
+            string linkId = linkInfo.GetLinkID();
+            
+            if (!string.IsNullOrEmpty(linkId))
+            {
+                // Trigger logic, e.g., Whisper the player!
+                EventBus.Publish(new WhisperPlayerEvent(linkId));
+            }
+        }
+    }
+}
+```
+
+**Note for specific PW Dialogues**: Legacy classes (such as `DlgNameLink.cs`) may implement a customized command pattern (e.g., `LinkCommand`, `MoveToLinkCommand` alongside `StyledTaskTraceText`) to process complex hyperlink commands recursively. However, for completely rewritten or standalone UI systems like standard Chat or logging panels, utilizing TextMeshPro's native `TMP_TextUtilities.FindIntersectingLink` combined with `IPointerClickHandler` is significantly faster, lightweight, and standard for Unity development.
