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.

The call that the message refers to. This is only applicable to messages of type
|
||
:attr:`MessageType.call`.
|
||
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.

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`]

||

|
||
message.
|
||
attachments: List[:class:`Attachment`]
|
||
A list of attachments given to a message.
|
||
pinned: :class:`bool`
|
||
Specifies if the message is currently pinned.
|
||
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.
|
