仅在满足条件时才启动discord.py命令冷却

可以使用多种方法来制作自己的冷却时间，这里有一个简单的方法可以解决问题。其背后的想法是让机器人“记住”上次有人使用此特定命令的时间，并在允许玩家移动之前对其进行检查。

from datetime import datetime, timedeltaon_cooldown = {} # Dictionary with user IDs as keys and datetime as valuesdestinations=["d1", "d2", "d3"] # List of valid arguments for the commandmove_cooldown = 5 # cooldown of the move command in seconds@bot.command()async def move(ctx, destination):    if destination in destinations:        author = ctx.author.id        try: # calculate the amount of time since the last (successful) use of the command last_move = datetime.now() - on_cooldown[author]         except KeyError: # the key doesn't exist, the player used the command for the first time # or the bot has been shut down since last_move = None on_cooldown[author] = datetime.now()        if last_move is None or last_move.seconds > move_cooldown: # move(...) on_cooldown[author] = datetime.now() # the player successfully moved so we start his cooldown again await ctx.send("You moved!")        else: await ctx.send("You're still on cooldown.")    else:        await ctx.send("This is not a valid destination")

注意：您可以在

@bot.command

装饰器后删除括号，也可以不必删除括号。
