此方法将使用Client.wait_For(),如果您有任何其他想法,可以轻松适应。
示例
@bot.command()
async def pages(ctx):
contents = ["This is page 1!", "This is page 2!", "This is page 3!", "This is page 4!"]
pages = 4
cur_page = 1
message = await ctx.send(f"Page {cur_page}/{pages}:\n{contents[cur_page-1]}")
# getting the message object for editing and reacting
await message.add_reaction("◀️")
await message.add_reaction("▶️")
def check(reaction, user):
return user == ctx.author and str(reaction.emoji) in ["◀️", "▶️"]
# This makes sure nobody except the command sender can interact with the "menu"
while True:
try:
reaction, user = await bot.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) == "▶️" and cur_page != pages:
cur_page += 1
await message.edit(content=f"Page {cur_page}/{pages}:\n{contents[cur_page-1]}")
await message.remove_reaction(reaction, user)
elif str(reaction.emoji) == "◀️" and cur_page > 1:
cur_page -= 1
await message.edit(content=f"Page {cur_page}/{pages}:\n{contents[cur_page-1]}")
await message.remove_reaction(reaction, user)
else:
await message.remove_reaction(reaction, user)
# removes reactions if the user tries to go forward on the last page or
# backwards on the first page
except asyncio.TimeoutError:
await message.delete()
break
# ending the loop if user doesn't react after x seconds
如果您的编辑器不支持直接粘贴表情符号,您可以使用this one 等网站来查找表情符号的 unicode。在这种情况下,向前箭头是\u25c0,向后箭头是\u25b6。
除此之外,你应该很高兴!该消息将在该消息不活动 60 秒后自行删除(即没有人对箭头做出反应),但如果您希望在删除前有更长的时间,只需更改数字即可。
或者,您可以添加第三个表情符号,例如十字架,它可以按需删除消息。
