Discord.py: Using Variable As Discord Embed color

Question

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)

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.

How do I fix this? Thanks.

Solution 1

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
)

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

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

Solution 2

You need to convert the user input in message.content to a RGB color value.

E.g. for green, what Embed expects would look like this:

discord.Embed(title="Hey", description="How are you?", color=0x00ff00)

So you could either let the users pass the color values directly:

color = int(message.content, 16)  # content should look like this: "0x00ff00"
discord.Embed(title="Hey", description="How are you?", color=color)

Or map some color names to the corresponding values:

color_name = message.content  # content should look like this: "green"

colors = {"green": 0x00ff00, "red": 0xff0000, "blue": 0x0000ff}

discord.Embed(title="Hey", description="How are you?", color=colors[color_name])

Solution 3

questions = ["What should be the name of the embed?", 
            "What should be the desc",
            "What is the colour of the embed?"]

answers = []

def check(m):
    return m.author == ctx.author and m.channel == ctx.channel 

for i in questions:
    await ctx.send(i)

    try:
        msg = await client.wait_for('message', timeout=15.0, check=check)
    except asyncio.TimeoutError:
        await ctx.send('You didn\'t answer in time, please be quicker next time!')
        return
    else:
        answers.append(msg.content)


title = answers[1]
desc = answers[2]
colour = answers[3]


embed = discord.Embed(title = f"{title}", description = f"{desc}", color = colour)

embed.set_footer(text = f"My embed")

await channel.send(embed = embed)

I think that this is an amazing question to be asked! I had a very similar issue when I was beginning to write Discord bots, and I spent hours scouring documentation trying to find an answer!

At least an example

No, in my situation I'm accepting different responses for different parts the embed until the bot gets to color. Here you can see where I'm waiting for the input: message = await self.bot.wait_for("message", check=check)

[Dom]

Ahh, I understand. This worked, thank you (:

[LiBa01]

I'm glad I could help. :)

[Dom]

I'll try this out, may be a bit difficult to implement it the way I'm trying but hey, worth a shot! Thanks for your contribution (:

[Dom]

Okay, so, I tried implementing this, but I get the error discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: int() can't convert non-string with explicit base

[StarbuckBarista]

I made a simple error in my code, and I am so sorry! Everything should now be working properly.
