There should be no need to create one of these manually.
Attributes
-----------
tts: :class:`bool`
Specifies if the message was done with text-to-speech.
This can only be accurately received in :func:`on_message` due to
a discord limitation.
type: :class:`MessageType`
The type of message. In most cases this should not be checked, but it is helpful
in cases where it might be a system message for :attr:`system_content`.
author: :class:`abc.User`
A :class:`Member` that sent the message. If :attr:`channel` is a
private channel or the user has the left the guild, then it is a :class:`User` instead.
content: :class:`str`
The actual contents of the message.
nonce
The value used by the discord guild and the client to verify that the message is successfully sent.
This is typically non-important.
embeds: List[:class:`Embed`]
A list of embeds the message has.
channel: Union[:class:`abc.Messageable`]
The :class:`TextChannel` that the message was sent from.
Could be a :class:`DMChannel` or :class:`GroupChannel` if it's a private message.
call: Optional[:class:`CallMessage`]
The call that the message refers to. This is only applicable to messages of type
:attr:`MessageType.call`.
reference: Optional[:class:`MessageReference`]
The message that this message references. This is only applicable to messages of
type :attr:`MessageType.pins_add` or crossposted messages created by a
followed channel integration.
.. versionadded:: 1.5
mention_everyone: :class:`bool`
Specifies if the message mentions everyone.
.. note::
This does not check if the ``@everyone`` or the ``@here`` text is in the message itself.
Rather this boolean indicates if either the ``@everyone`` or the ``@here`` text is in the message
**and** it did end up mentioning.
mentions: List[:class:`abc.User`]
A list of :class:`Member` that were mentioned. If the message is in a private message
then the list will be of :class:`User` instead. For messages that are not of type
:attr:`MessageType.default`\, this array can be used to aid in system messages.
For more information, see :attr:`system_content`.
.. warning::
The order of the mentions list is not in any particular order so you should
not rely on it. This is a discord limitation, not one with the library.
channel_mentions: List[:class:`abc.GuildChannel`]
A list of :class:`abc.GuildChannel` that were mentioned. If the message is in a private message
then the list is always empty.
role_mentions: List[:class:`Role`]
A list of :class:`Role` that were mentioned. If the message is in a private message
then the list is always empty.
id: :class:`int`
The message ID.
webhook_id: Optional[:class:`int`]
If this message was sent by a webhook, then this is the webhook ID's that sent this
message.
attachments: List[:class:`Attachment`]
A list of attachments given to a message.
pinned: :class:`bool`
Specifies if the message is currently pinned.
flags: :class:`MessageFlags`
Extra features of the message.
.. versionadded:: 1.3
reactions : List[:class:`Reaction`]
Reactions to a message. Reactions can be either custom emoji or standard unicode emoji.
activity: Optional[:class:`dict`]
The activity associated with this message. Sent with Rich-Presence related messages that for
example, request joining, spectating, or listening to or with another member.
It is a dictionary with the following optional keys:
- ``type``: An integer denoting the type of message activity being requested.
- ``party_id``: The party ID associated with the party.
application: Optional[:class:`dict`]
The rich presence enabled application associated with this message.
It is a dictionary with the following keys:
- ``id``: A string representing the application's ID.
- ``name``: A string representing the application's name.
- ``description``: A string representing the application's description.
- ``icon``: A string representing the icon ID of the application.
- ``cover_image``: A string representing the embed's image asset ID.
