| methodName | The name of the method to call. |
| value | An optional parameter value to pass to the called method. |
| options | Should an error be raised if the method doesn't exist on the target object? |
Calls the method named methodName on every MonoBehaviour in this GameObject.
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).
using UnityEngine;
public class Example : MonoBehaviour { void Start() { // Calls the function ApplyDamage with a value of 5 // Every script attached to the GameObject // that has an ApplyDamage function will be called. gameObject.SendMessage("ApplyDamage", 5.0); } }
public class Example2 : MonoBehaviour { public void ApplyDamage(float damage) { print(damage); } }
