public void SendMessageUpwards(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 and on every ancestor of the behaviour.

The receiving method can choose to ignore the argument by having zero parameters. 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 SetActive function).

using UnityEngine;

public class Example : MonoBehaviour { void Start() { // Calls the function ApplyDamage with a value of 5 gameObject.SendMessage("ApplyDamage", 5.0); } }

public class Example2 : MonoBehaviour { public void ApplyDamage(float damage) { print(damage); } }
