+# Event::Invoke
+
+```cpp
+void Invoke(Args... args);
+```
+
+调用所有订阅的回调。
+
+**描述**
+
+依次调用所有已订阅的回调函数。在调用前会自动处理待退订的回调。回调是在锁外执行的，因此可以在回调中安全地进行订阅/退订操作。线程安全。
+
+**参数：**
+- `args` - 传递给回调的参数
+
+**复杂度：** O(n) 其中 n 为订阅数量
+
+**示例：**
+
+```cpp
+#include <XCEngine/Core/Event.h>
+
+using namespace XCEngine::Core;
+
+// 无参数事件
+Event<> frameEndEvent;
+frameEndEvent.Subscribe([]() {
+    printf("Frame ended\n");
+});
+
+// 带参数事件
+Event<int, const char*> playerDiedEvent;
+playerDiedEvent.Subscribe([](int playerId, const char* reason) {
+    printf("Player %d died: %s\n", playerId, reason);
+});
+
+// 触发事件
+frameEndEvent.Invoke();
+playerDiedEvent.Invoke(1, "fell off a cliff");
+```
