TextService:FilterAndTranslateStringAsync

Deprecated. This method is no longer supported and should not be used. All calls return an empty object.

This method is no longer supported and should not be used. Translating chat messages is only available via TextChatService.

TextService:FilterStringAsync

This method filters a string being received from a user and returns a TextFilterResult which can be used to distribute the correctly filtered text accordingly.

This method should be called once each time a user submits a message. If it fails, do not display the text to any user.

See text filtering for usage guidelines and examples.

Notes

Parameters

NameTypeDefaultDescription
stringToFilterstringThe text to be filtered.
fromUserIdint64The Player.UserId of the player filtering the text.
textContextTextFilterContextPrivateChatThe context that the filtered message will be used in. This parameter does not impact the filtered result of the query and is only used to improve Roblox's text filtering.

Returns

TypeDescription
TextFilterResultA TextFilterResult that wraps the filtered text and exposes methods for retrieving it in the form appropriate for each audience.
FieldValue

securityNone
thread safetyUnsafe

TextService:GetFamilyInfoAsync

Returns a table containing the name and faces of a font family. If the font family has already been loaded by a previous call to GetFamilyInfoAsync(), ContentProvider:PreloadAsync(), or a text object with the TextLabel.FontFace property set, then the method returns without yielding.

This method can fail because of network errors and should be wrapped in LuaGlobals.pcall() to catch and handle errors.

Parameters

NameTypeDefaultDescription
assetIdContentIdAsset ID of the font family to look up.

Returns

TypeDescription
DictionaryThe information about the font family.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
capabilities["UI"]

TextService:GetTextBoundsAsync

Computes the Vector2 dimensions (in pixels) that will be taken up with text when using parameters defined in a GetTextBoundsParams object. This method is similar to GetTextSize() but uses the Font object which has access to more fonts than Font.

This method is a useful alternative to the TextBounds property of the TextLabel/TextButton objects, since GetTextBoundsAsync() can calculate the dimensions required by a particular text string in a TextLabel or TextButton before such an object is created or text property set.

This is a yielding method because some fonts may need to be loaded in order to measure them. As a result, it should be wrapped in LuaGlobals.pcall() to catch and handle errors. If the font is already loaded, it will not yield; ContentProvider:PreloadAsync() can be used to make sure a font is loaded.

Parameters

NameTypeDefaultDescription
paramsGetTextBoundsParamsA reference to a GetTextBoundsParams object.

Returns

TypeDescription
Vector2The size of the text as a Vector2.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
capabilities["UI"]

TextService:GetTextSize

Computes the Vector2 dimensions (in pixels) that will be taken up with text when using the specified formatting parameters and size constraints.

This method is a useful alternative to the TextBounds property of the TextLabel/TextButton objects, since GetTextSize() can calculate the dimensions required by a particular text string in a TextLabel or TextButton before such an object is created or text property set.

This method is limited to fonts under Font. To access more fonts under Font, use GetTextBoundsAsync() instead.

Parameters

NameTypeDefaultDescription
stringstringThe string for which the text size is to be calculated.
fontSizeintThe integer representing the font size used. Does not accept an FontSize value.
fontEnum.FontThe font used.
frameSizeVector2The GuiBase2d.AbsoluteSize of the text object to be used. Required to compute how the text will wrap.

Returns

TypeDescription
Vector2The size of the space required, in pixels, by the string with the specified formatting.
FieldValue
securityNone
thread safetyUnsafe
capabilities["UI"]

TextService:GetTextSizeOffsetAsync

Returns the offset used to up-scale text based on GuiService.PreferredTextSize, a property which may change through the player's setting in the Roblox or in‑experience Settings menus.

This offset can be used as an additive value to adjust the core height value of a TextLabel or TextButton based on PreferredTextSize.

Note that, currently, the fontSize and font parameters do not affect the outcome and this method returns merely the offset as described above. Also note that this method can fail because of network errors and should be wrapped in LuaGlobals.pcall() to catch and handle errors.

Parameters

NameTypeDefaultDescription
fontSizeintThe font size, in offsets. This parameter currently does not affect the returned offset.
fontDatatype.FontThe font. This parameter currently does not affect the returned offset.

Returns

TypeDescription
floatThe offset, in pixels, to add to the height of a TextLabel or TextButton to up-scale it for the player's current PreferredTextSize setting.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
