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

Parameters

methodNameThe name of the method to call.
valueAn optional parameter value to pass to the called method.
optionsShould an error be raised if the method doesn't exist on the target object?

Description

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

The receiving method can choose to ignore the argument by having zero parameters. If options is set to SendMessageOptions.RequireReceiver an error is printed if 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 SetActive function).
