Discord.py:使用变量作为 Discord 嵌入颜色

问题描述

所以我正在尝试为我的不和谐机器人创建一个嵌入构建器的命令.我希望命令的用户能够输入嵌入颜色的十六进制值.这是我尝试过的:

so I'm trying to make a command for my discord bot that is an embed builder. I want the user of the command to be able to input a hex value for the color of the embed. Here is what I've tried:

value = message.content

embed=discord.Embed(title="Hey", description="How are you?", color=value)
await output.edit(content=None, embed=embed)

但是，当我这样做时，我得到了错误:

However when I do this I get the error:

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: Expected discord.Colour, int, or Embed.Empty but received str instead.

我该如何解决这个问题?谢谢.

How do I fix this? Thanks.

推荐答案

我将继续假设您所期望的输入类似于 #ffffff，请如果我错了，请纠正我.为了将其转换为 Discord 可以读取的内容，我们可以使用以下方法.我将假设 message 是您等待他们响应的消息对象.

I'm going to go ahead and assume that the input you are expecting is something along the lines of #ffffff, and please do correct me if I am mistaken. In order to convert this into something that Discord can read, we can use the following method. I'm going to me assuming that message is the message object that you wait for them to respond with.

sixteenIntegerHex = int(message.content.replace("#", ""), 16)
readableHex = int(hex(sixteenIntegerHex), 0)

embed = discord.Embed(
    title = "Hey",
    description = "How are you?",
    color = readableHex
)

您甚至可以将两个整数转换语句合并为一个！

You could even merge the two integer conversion statements into one!

readableHex = int(hex(int(message.content.replace("#", ""), 16)), 0)
