unity3D之发送广播与消息

游戏对象之间发送的广播与消息分为三种：第一种向子对象发送，将发送至该对象的同辈对象或者子孙对象中；第二种为给自己发送，发送至自己本身对象；第三种为向父对象发送，发送至该对象的同辈或者父辈对象中；

//向子类发送消息、

gameObject.BroadcastMessage("message","BroadcastMessage");

//给自己发送消息

gameObject.SendMessage("message","BroadcastMessage");

//向父类发送消息

gameObject.SendMessageUpwards("message","BroadcastMessage");

//接收父类发送的消息

function ReceiveBroadCastMessage(str:String){

}

//接收自己发送的消息

functio ReceiveSendMessage(str:String){

}

//接收子类发送的消息

function ReceiveSendMessageUpwards(str:String){

}
