Chapter 12 - 交互四大组件之:按钮

修改 events/interactionCreate.js

对应的 commit: https://github.com/wtflmao/discord_bot_example/commit/eef8c0f3fb0ebed69c63eb776128acb28ceb8b3f https://gitee.com/wtflmao/discord_bot_example/commit/eef8c0f3fb0ebed69c63eb776128acb28ceb8b3f

在文件的最后那块儿附近,找到最后一个 else,在这个 else 上面插入一种新情况,用于按钮:

js
else if (interaction.isButton()) {
	console.log("a button!");
}

新建一个操作行 ActionRow

上来先导入需要的 ActionRowBuilder,用于建立操作行 ActionRow。

通过 new ActionRowBuilder() 新建。

js
const { ActionRowBuilder } = require('discord.js');

let row = new ActionRowBuilder()
    .addComponents(
        ... // 此处确定你需要的组件
    );

新建按钮 Button

上来先导入需要的 ActionRowBuilderButtonBuilder。前者用于建立操作行,后者用于建立一个按钮。按钮需要被包含到一行操作行上去。

通过 new ButtonBuilder() 新建一个按钮。

js
const { ActionRowBuilder, ButtonBuilder } = require('discord.js');

let row = new ActionRowBuilder()
    .addComponents(
        new ButtonBuilder()
	        // 设置按钮自定义 ID
            .setCustomId('button1')

			// 设置按钮标签,就是按钮上的字
            .setLabel('Click me!')

			// 设置按钮样式,具体在下一小节有讲
            .setStyle(ButtonStyle.Primary)

			// 设置按钮是否被禁用,这里的 false 表示未被禁用
            .setDisabled(false)

			// 设置一个 Emoji 前缀
            .setEmoji('😀'),
    );

这个按钮的样式如图: image

五种按钮的基本样式

按钮(Button)是组件(Component)的一种,通过 components: [] 指定哪些按钮将发送出去。

一条消息里最多加入五个按钮。准确来说,是最多五个组件(components),按钮是组件的一种。

按钮有五种样式:Primary、Secondary、Success、Danger 和 Link,下面用 commands/buttons/stylishButton.js 来说明:

            button1.push(new ButtonBuilder()

                    .setLabel("Click me!")

                    // you can't .setCustomId() to a Link button

            .addComponents(button1d);

        const rowPrimary2D = new ActionRowBuilder()
            .addComponents(

                    .setCustomId(`owo`)
                    .setLabel("owo")

        const rowDangerD = new ActionRowBuilder()

                    .setCustomId('b4d')
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Danger)
                    .setDisabled(true),
            );

        const rowLinkD = new ActionRowBuilder()
            .addComponents(
                new ButtonBuilder()
                    // 你不能对一个链接按钮设置 customId 属性
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Link)
                    .setURL("https://support.discord.com/hc/en-us")
                    .setDisabled(true),
            );

        // 这条消息里我们插了三行 ActionRow 进去。
        await interaction.reply({ content: 'These are some Primary buttons:', components: [rowPrimary, rowPrimaryD, rowPrimary2D], ephemeral: false });

        // 这条消息里我们插了两行 ActionRow 进去。
        await interaction.followUp({ content: 'These are two Secondary buttons. They are NOT on the same row:', components: [rowSecondary, rowSecondaryD], ephemeral: false });

        // 这条消息里我们插了一行 ActionRow 进去。
        await interaction.followUp({ content: 'These are two Success buttons. They are on the same row:', components: [rowSuccess], ephemeral: false });

        // 这条消息里我们插了两行 ActionRow 进去。
        await interaction.followUp({ content: 'These are two Danger buttons. They are NOT on the same row:', components: [rowDanger, rowDangerD], ephemeral: false });

        // 这条消息里我们插了两行 ActionRow 进去。
        await interaction.followUp({ content: 'These are two Link buttons. They are NOT on the same row:', components: [rowLink, rowLinkD], ephemeral: false });
    },
};

使用按钮样式时,要注意第一行要导入 ButtonStyle。

我们可以看到,一个回复消息,其实有(至少)四个域:contentcomponentsembedsephemeral。其中,content 是必选的,其余是可选的。当只有 content 时,"content" 标签可以省略,如:await interaction.reply("1+1=2");

效果图: image

只有链接按钮可以有一个 url。链接按钮不能有 customId,并且在单击时不发送交互事件。

通过 .setDisabled(true) 为一个按钮设置不可点击的属性,这样用户就不能点击这个按钮了。但是你不能向一个已经建成的(即new ActionRowBuilder()过的)按钮变量设置新的属性,你必须重新 new 一个按钮出来。

带有前缀 Emoji 的按钮

下面用 commands/buttons/emojiButton.js 来说明:

js
const { ActionRowBuilder, ButtonBuilder, ButtonStyle, SlashCommandBuilder } = require('discord.js');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('emojibutton')
        .setDescription('Replies with a button, bu stylish!'),

    async execute(interaction) {

        const row = new ActionRowBuilder()
            .addComponents(
                new ButtonBuilder()
                    .setCustomId('b1')
                    .setLabel('Click me!')
                    .setStyle(ButtonStyle.Primary)
                    .setEmoji('😀'),
                new ButtonBuilder()
                    .setCustomId('b2')
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Secondary)
                    .setEmoji('😁'),
                new ButtonBuilder()
                    .setCustomId('b3')
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Success)
                    .setEmoji('🤣'),
                new ButtonBuilder()
                    .setCustomId(`b4`)
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Danger)
                    .setEmoji('😇'),
                new ButtonBuilder()
                    // you cant .setCustomId() to a Link button
                    .setLabel("Click me!")
                    .setStyle(ButtonStyle.Link)
                    .setURL("https://support.discord.com/hc/en-us")
                    .setEmoji('🤪'),
            );

        // 一条消息里最多五行 ActionRow,每一行 ActionRow 里最多插入五个包括按钮在内的组件
        await interaction.reply({ content: 'There are some buttons:', components: [row], ephemeral: false });},
};

效果图: image

注意,这里 .setEmoji() 只能设置一个 emoji,且只会出现在按钮 Label 的前面。

还有,一条消息里最多五行 ActionRow,每一行 ActionRow 里最多插入五个按钮,准确来说,是最多五个组件(components),按钮是组件的一种。如需五个以上的按钮,可以尝试回复多次,比如 .followUp()

带有嵌套元素和按钮的回复

通过 new EmbedBuilder() 新建一个嵌套元素。注意第一行要导入 EmbedBuilder。

通过 embeds: [] 指定哪些嵌套元素将发送出去。

嵌套元素不是按钮专属,嵌套元素其实和按钮等组件是平级的。

下面的源码注释我个人认为该有的都有了,清晰明了。就不再在这里费笔墨再写一遍了。

  • deleteReply()
  • followUp()

消息组件收集器:处理按钮被按下后的交互操作

我们需要建立一个 Discord.js 为我们提供的一种“收集器”(Collector)来监听一种交互:按钮被按下这种交互。

其实消息组件收集器可以收集任何消息组件,但是这里我们只在乎按钮的交互。

消息组件收集器,这种收集器有个特点,就是 Discord 期望你的机器人在 3 秒内对所有交互做出响应,即使是您不想收集的交互也是如此。出于这个原因,实践中的许多情况下,在 filter 中上来就来个 .deferUpdate(),甚至放弃使用 filter,直接让 collector 来者不拒,上来同样先 .deferUpdate()

我们这里没有这么做。

下面的源码注释我个人认为该有的都有了,清晰明了。就不再在这里费笔墨再写一遍了。

下面用 commands/buttons/deferAndDelete.js 来说明:

效果图: image 然后 image 然后 image

需要注明的是,我们这里的收集器“监听”的是频道(Channel)里的组件事件。消息组件收集器还有另一种监听对象:消息(Message)。

监听某个 Channel:

js
const collector = interaction.channel.createMessageComponentCollector();

此时,只要收集器仍在工作,则该收集器的目标频道里的所有 MessageComponent 事件都可以成为收集器的收集对象。比如本例中,哪怕之前机器人已重启过好几次了,只要有人执行了斜杠命令 /button,那么哪怕是(在这个频道里)上个月的按钮,只要满足了 filter 的条件,也能够被收集器收集到,进而干该干的事。

监听某个 Message:

js
message = await interaction.fetchReply();
const collector = message.createMessageComponentCollector();

此时,只要监听某条特定消息的收集器停止了工作,那么在本例中,没有其他的收集器可以在收集到该按钮的组件事件了,哪怕满足 filter 的条件了也不行。本例使用的是对象是频道的收集器。

你可以自由选择是使用对象是频道的消息组件收集器,还是使用对象是消息的消息组件收集器,来简化你的任务。
