JavaScript => BroadcastMessage(methodName: string, parameter: object = null, options: SendMessageOptions = SendMessageOptions.RequireReceiver): void;
C# => void BroadcastMessage(string methodName, object parameter = null, SendMessageOptions options = SendMessageOptions.RequireReceiver);

Description 描述

Calls the method named /methodName/ on every MonoBehaviour in this game object or any of its children.

对此游戏对象及其子对象的所有MonoBehaviour中调用名称为methodName的方法。

The receiving method can choose to ignore /parameter/ 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.

接收消息的方法可以通过不要参数的方法来选择忽略参数.当选项被设置为SendMessageOptions.RequireReceiver时，如果消息没有被任何一个组件处理，则会打印一个错误.

JavaScript:

	/// Calls the function ApplyDamage with a value of 5
	gameObject.BroadcastMessage ("ApplyDamage", 5.0);
 
	// Every script attached to the game object and all its children
	// that has a ApplyDamage function will be called.
	function ApplyDamage (damage : float) {
		print (damage);
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void ApplyDamage(float damage) {
        print(damage);
    }
    void Example() {
        gameObject.BroadcastMessage("ApplyDamage", 5.0F);
    }
}
