public static void Emit(string eventType, object args = null, int targetId = -1, EventDataSerialization eventDataSerialization = EventDataSerialization.JsonUtility)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The message's type name.**** (\[Object]\(https\://learn.microsoft.com/dotnet/api/system.object)): The arguments sent with the message.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): When you send the event to a specific connection, this is the connection ID. By default it is set to -1, which sends the message to all other EventServices.**** (\[EventDataSerialization]\(/engine/6000.6/script-reference/unityeditor/mpe/eventdataserialization)): Specifies how to serialize the request's arguments. This can be standard JSON, or JSON annotated with JsonUtility. You can use the latter to convert the argument to a concrete Unity object that supports [JsonUtility.FromJson](/engine/6000.6/script-reference/unityengine/jsonutility/fromjson.md).
