也有有段时间没写godot了，今天这个是通过插件实现一个在线电台播放器。插件看起来也不复杂。
插件地址：https://github.com/jefvaia/Godot-WebRadio
为了获取到消息，插件中webradiostreamplayer.gd这三个文件需要稍作修改。主要是添加一个buffer_ready信号。
extends AudioStreamPlayer
class_name WebRadioStreamPlayer
signal buffer_ready
@export var url: String
func _ready() -> void:
var http_instance = WebRadioStreamHelper.get_radio(url)
if http_instance == null:
http_instance = WebRadioStreamHelper.add_radio(url)
if http_instance.player_done_connected == false:
self.finished.connect(http_instance.player_done)
http_instance.player_done_connected = true
http_instance.buffer_ready.connect(_refresh_stream)
func _refresh_stream(new_stream: AudioStreamMP3):
emit_signal("buffer_ready") # 触发信号
self.stream = new_stream
self.play(0)
工程中引用此插件并启用。
添加两个控件：Button和Timer。分别用于换台和换台等待效果。插件的引用是通过代码进行的。
以下是完整的场景代码，不足50行。其实Timer控件也不是必须的，只是实现一个载入等待的效果。
extends Node2D
var urls = [
