使用.setselfdeaf()时如何修复此ReferenceError ?

Question

我试图在我的代码中使用。setselfdeaf()，但我无法弄清楚。我所尝试的每一种方法都导致了程序在执行时崩溃。

有人能帮我用一下吗?我想要的是每次加入语音频道时，聋哑的机器人本身。

编辑:根据请求添加了我得到的错误和更新的代码。

得到的错误:

Answer 1

如果您读取错误ReferenceError: connection is not defined，它会告诉您哪里出错了。以下代码中的connection不是变量:

client.on("voiceStateUpdate", (oldVoiceState, newVoiceState) => {
if (newVoiceState.id == client.user.id) {
connection.voice.setSelfDeaf(true);
};
});

在newVoiceState上有一个connection属性，尽管这不是您在此场景中想要的。您需要使用VoiceState:

中的.setSelfDeaf方法

client.on("voiceStateUpdate", (oldVoiceState, newVoiceState) => {
if (newVoiceState.id == client.user.id) {
newVoiceState.setSelfDeaf(true);
};
});
