public void SendMessage (string methodName, object value= null, SendMessageOptions options= SendMessageOptions.RequireReceiver);
public void SendMessage (string methodName, SendMessageOptions options);


methodName Name of the method to call.
value Optional parameter for the method.
options Should an error be raised if the target object doesn't implement the method for the message?


Calls the method named methodName on every MonoBehaviour in this game object.

The receiving method can choose to ignore the argument by having zero arguments. If options is set to SendMessageOptions.RequireReceiver an error is printed when the message is not picked up by any component.

Note that messages will not be sent to inactive objects (ie, those that have been deactivated in the editor or with the GameObject.SetActive function).
