TextChatCommand
Inherits from: Instance → Object
Represents a text chat command. Can be used to create custom text chat commands when parented to TextChatService.
Custom commands can have up to two aliases, and the Triggered event fires when a user's message matches the value of either the PrimaryAlias or SecondaryAlias. For an example of custom commands, see Custom text chat commands.
To learn more about using TextChatService, see In-experience text chat.

TextChatCommand.AutocompleteVisible
Whether this TextChatCommand appears as a suggestion in the chat autocomplete menu. Defaults to true.
When true, PrimaryAlias is offered in the autocomplete list. Set to false to hide it from suggestions; the command still works when typed in full via PrimaryAlias or SecondaryAlias.
Autocomplete itself is controlled by ChatInputBarConfiguration.AutocompleteEnabled.
| Field | Value |

| type | boolean |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["Chat"] |
TextChatCommand.Enabled
Determines whether the TextChatCommand is enabled.
When disabled, messages that match the value of PrimaryAlias or SecondaryAlias are not sunk and is sent to other users.
Use this to disable default commands on a case-by-case basis.
| Field | Value |
|---|---|
| type | boolean |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["Chat"] |
TextChatCommand.PrimaryAlias
A primary alias used to trigger the TextChatCommand.
If a user sends a message with TextChannel:SendAsync() that matches the PrimaryAlias, the message is not sent and instead TextChatCommand.Triggered is fired.
| Field | Value |
|---|---|
| type | string |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["Chat"] |
TextChatCommand.SecondaryAlias
A secondary alias used to trigger the TextChatCommand, in addition to its PrimaryAlias.
If a user sends a message with TextChannel:SendAsync() that matches the SecondaryAlias, the message is not sent and instead TextChatCommand.Triggered is fired, exactly as it is for the PrimaryAlias. Matching is case-insensitive, and the alias must be followed by the end of the message or a space, so a SecondaryAlias of "/e" matches "/e" and "/e dance" but not "/emote".
Defaults to an empty string, in which case only the PrimaryAlias triggers the command.
| Field | Value |

Events
| Name | Type / Returns | Description |
|---|---|---|
| TextChatCommand.Triggered | An event that developers can bind to execute commands. |
Inherited from Instance
| Name | Type / Returns | Description |
|---|---|---|
| Instance.AncestryChanged | Fires when the Instance.Parent property of this object or one of its ancestors is changed. | |
| Instance.AttributeChanged | Fires whenever an attribute is changed on the Instance. | |
| Instance.ChildAdded | Fires after an object is parented to this Instance. | |
| Instance.childAdded | ||
| Instance.ChildRemoved | Fires after a child is removed from this Instance. | |
| Instance.DescendantAdded | Fires after a descendant is added to the Instance. | |
| Instance.DescendantRemoving | Fires immediately before a descendant of the Instance is removed. | |
| Instance.Destroying | Fires immediately before (or is deferred until after) the instance is destroyed via Instance:Destroy(). | |
| Instance.StyledPropertiesChanged | Fires whenever any style property is changed on the instance, including when a property is set to nil. |
Inherited from Object
| Name | Type / Returns | Description |
|---|---|---|
| Object.Changed | Fires immediately after a property of the object changes, with some limitations. |
TextChatCommand.Triggered
An event that developers can bind to execute commands.
When a user sends a message to the server via TextChannel:SendAsync(), the message is intercepted by the TextChatCommand and not replicated to other users if the content of the message matches the PrimaryAlias or SecondaryAlias.
For example, for a TextChatCommand with TextChatCommand.PrimaryAlias as "mute", if a user sends "/mute SomeUserName", then the relevant TextChatCommand for mute will fire its TextChatCommand.Triggered. The message "/mute SomeUserName" is not replicated to other users.
Parameters
| Name | Type | Default | Description |
|---|---|---|---|
| originTextSource | TextSource | A reference to the TextSource responsible for triggering the command via TextChannel:SendAsync(). | |
| unfilteredText | string | The full, unfiltered text used to trigger the command that can be used to dissect parameters from the command message. |
| Field | Value |
|---|---|
| security | None |
