discord.py 嵌入帶有反應頁面的幫助命令

Question

我正在嘗試制作一個包含多個頁面的幫助命令，您可以使用反應來回 go。 它工作正常，但是當您再次轉到第 2 頁和 go 時，沒有任何反應。 當您 go 到第 1 頁並嘗試返回 go 時也是如此。 我怎樣才能做到這一點，當您嘗試 go 經過最后一頁時，它會返回到第一頁，而當您嘗試 go 在第一頁之前時，它會將您帶到最后一頁？

避免重復，在你的循環中：

while True:

    try:
        reaction, user = await client.wait_for("reaction_add", timeout=60, check=check)
        # waiting for a reaction to be added - times out after x seconds, 60 in this
        # example

        if str(reaction.emoji) == "▶️":
            cur_page += 1
            

        elif str(reaction.emoji) == "◀️": 
            cur_page -= 1

        if cur_page > pages: #check if forward on last page
          cur_page = 1 
        elif cur_page < 1: #check if back on first page
          cur_page = pages 
        await message.edit(embed=contents[cur_page-1])
        await message.remove_reaction(reaction, user)

        
    except asyncio.TimeoutError:
        await message.delete()
        break
