Advanced Text Generator is a text rendering module that employs Harfbuzz, ICU, and FreeType to deliver comprehensive Unicode support and text shaping capabilities.
With Advanced Text Generator, you can use a wide array of languages and scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary, such as right-to-left (RTL) languages like Arabic and Hebrew.
To use Advanced Text Generator, you must use a font asset that supports the language you want to use. For example, if you want to use Arabic, you must use a font asset that supports Arabic. Advanced Text Generator only supports dynamic font assets. Before using Advanced Text Generator in your project, you must import the font into your project and create a dynamic font asset from it.
To use Advanced Text Generator in UI Builder, do the following:
VisualElement
class. You can style the look, define the behaviour, and display it on screen as part of the UI. More infoTo use Advanced Text Generator in USS, set -unity-text-generator
to advanced
. For example:
.labelText {
-unity-text-generator: advanced;
}
To use Advanced Text Generator in C# scripts, set TextGeneratorType
to Advanced
. For example:
textElement.style.unityTextGenerator = new StyleEnum<TextGeneratorType>(TextGeneratorType.Advanced);
This section explains how cursor movement behaves in the input fields when handling bidirectional (BIDI) text.
Unity currently follows a Logical Cursor Movement approach. This means the cursor moves through BIDI text based on the direction of the segment of text. For example, using the left arrow key in a sentence with Arabic and English text, it moves right-to-left through Arabic, then jumps at the leftmost character in the English segment and continues left-to-right until it reaches the end of the segment.
Some applications follow a Visual Cursor Movement
approach. This means the cursor moves to the next visual character regardless of the direction of the text, which can sometimes feel more intuitive for users. We plan to make the cursor movement mode an option in future releases.
You can enable auto sizing for text with Best Fit. The Best Fit feature allows you to set a minimum and maximum font size for the text element. The text element adjust its font size dynamically based on the content and available space within the range.
Best Fit also supports the following features:
You can enable auto sizing in UI Builder, USS, or C# scripts.
In USS, set the -unity-text-auto-size
property to best fit
with a minimum and maximum font size. For example:
.labelText {
-unity-text-generator: advanced;
-unity-text-auto-size: best-fit 5px 100px;
}
To enable auto sizing in C# scripts, use the TextAutoSizeMode
property. For example:
textElement.style.unityTextAutoSize = new StyleTextAutoSize(new TextAutoSize(TextAutoSizeMode.BestFit, minSize: 10, maxSize: 100));
Advanced Text Generator has the following limitations:
When you use Advanced Text Generator, your project includes an icudt73l
file that has a significant memory footprint of 4.8MB
. This will be improved in future releases.
