Summary: Learn how to implement Bidirectional (Bidi) text rendering in Java games and graphics applications to support languages such as Arabic and Hebrew.
---
Bidirectional (Bidi) text rendering is essential for supporting languages like Arabic and Hebrew, which are written from right to left (RTL). In Java games and graphics applications, implementing Bidi text rendering ensures that text is displayed correctly, maintaining proper visual order regardless of the language directionality. Let's delve into how you can achieve this in your Java projects.
Understanding Bidirectional Text Rendering
In languages with RTL scripts, such as Arabic and Hebrew, text elements are ordered from right to left, while numbers and other embedded LTR content retain their original order. Implementing Bidi text rendering involves correctly handling the logical order of text elements and ensuring they display properly on the screen.
Using Java's Bidi Class
Java provides the java.text.Bidi class to handle bidirectional text rendering. This class allows you to analyze and manipulate text containing both RTL and LTR characters. Here's a basic example of how you can use the Bidi class:

In this example, the Arabic text "مرحبا بالعالم" is reordered using the writeReordered() method according to the specified directionality.
Integrating Bidi into Java Games and Graphics
When incorporating Bidi text rendering into Java games and graphics applications, you need to consider the rendering framework you're using. Whether you're working with JavaFX, Swing, or a custom graphics library, the approach remains similar:
Text Analysis: Analyze the text to determine its directionality using the Bidi class.
Text Rendering: Render the text on the screen, applying any necessary transformations to ensure correct visual order.
Below is a simplified example illustrating how you might integrate Bidi text rendering into a JavaFX application:

Conclusion
Implementing Bidi text rendering in Java games and graphics applications is crucial for supporting languages with RTL scripts. By leveraging Java's Bidi class and integrating it into your rendering framework of choice, you can ensure that text is displayed correctly, maintaining proper visual order regardless of the language directionality.
