discord 機器人（python）“wait_for”“reaction_add”復制嵌入

Question

我一直在嘗試制作嵌入以顯示戲劇擁有的角色列表時遇到問題。 我基本上想要：left_arrow: 和:right_arrow: emojis 作為對用戶擁有的長字符數據庫之間左右平移的反應。

我確實設法做到了，但是我注意到，如果我在一個超時之前使用兩次顯示所有字符的嵌入的命令，然后單擊向左箭頭查看下一頁，它將轉到下一頁兩種嵌入，而不僅僅是我反應的那個。

這是我的源代碼。

@commands.command(aliases=["collection", "c"])
@commands.cooldown(1, 5, commands.BucketType.user)
async def characters(self, ctx):
    if not await bot.check_channel_permissions(ctx.author, ctx.channel): # Checks if the bot can send messages in the channel.
        return

    playerData = await bot.get_player_data(ctx.author, ctx.channel) # Returns the user's data.

    if playerData:

        if len(playerData["Characters"]) > 0: # Checks amount of characters the user owns.

            if len(playerData["Characters"]) > 20: # Player owns 20 so it will create an embed with reactions.

                global pageNumber
                global maxPages
                pageNumber = 1
                maxPages = math.ceil(len(playerData["Characters"]) / 20)

                embed = await characters.setupEmbed(self, playerData, ctx.author, pageNumber)

                currentEmbed = await ctx.channel.send(ctx.author.mention, embed=embed)

                await currentEmbed.add_reaction("⬅")
                await currentEmbed.add_reaction("➡")

                async def listenForRection(self, mainUser): # Waits until the user reacts with the left or right arrow in order to edit the current embed.

                    global pageNumber # the current page (20 characters are shown a page)
                    global maxPages # the max amount of pages the user can pan between.

                    def check(reaction, reactionuser):
                        if reactionuser != mainUser:
                            return False
                        elif str(reaction.emoji) == '⬅' and pageNumber > 1:
                            return True
                        elif str(reaction.emoji) == '➡' and pageNumber < maxPages:
                            return True
                        else:
                            return False

                    try:
                        reaction, reactionuser = await self.client.wait_for(
                            "reaction_add",
                            timeout=60,
                            check=check
                        )
                    except:
                        asyncio.TimeoutError
                        await currentEmbed.edit(content="Timed out.")
                    else:
                        if str(reaction.emoji) == '⬅':
                            pageNumber += -1
                        elif str(reaction.emoji) == "➡":
                            pageNumber += 1
                        newEmbed = await characters.setupEmbed(self, playerData, mainUser, pageNumber) # Returns an embeded list given the page number and info on the user.
                        await currentEmbed.edit(embed=newEmbed) # re-edits the current embed to show the next or previous page.
                        await listenForRection(self, mainUser) # re-runs the function again to listen for the next reaction.

                await listenForRection(self, ctx.author) # runs the listener once so that it can begin detecting and re-running on its own.


            else: # player will get an embeded list with no reactions since they only have 1 page of characters.
                embed = await characters.setupEmbed(self, playerData, ctx.author, 1)
                await ctx.channel.send(ctx.author.mention, embed=embed)
        else:
            await ctx.reply("You don't have any characters.")

會發生什么是我運行一次命令，它工作得很好。 然后，當我在超時之前再次運行它並單擊一個反應時，它要么不起作用，要么在新嵌入和舊嵌入上都運行。 我花了很多時間嘗試多種事情並進行搜索，但除了在修復當前錯誤后立即創建一個新錯誤之外，我並沒有做太多事情。

實際上有一個用於制作分頁菜單的 ext 庫，稱為discord-ext-menus 。 它為您完成大部分工作，因此您不必創建自己的。
