Installation

ℹ️ You need to have TextMeshPro plugin in your project. You can install TMPro via Package Manager. DO NOT Install Text Mesh Pro from Asset Store.

from .unitypackage file

Download the latest unitypackage file from the releases section and import it into your project from "Assets -> Import Package -> Custom Package..." menu in Unity.

from OpenUPM

hk1ll3r maintains a package manager version of this repo on OpenUPM.

In Project Settings window, add OpenUPM as a scoped registry or if you have already added it, add the new scope to it.

Then in Package Manager window, change scope to My Registries. Select "RTL Text Mesh Pro" package and press Install.

The sample scenes and demo resources (fonts, shaders, etc.) are included in the package as a .unitypackage file. You need to import those into your Assets folder to use them. From the project window navigate to the package folder and double click "RTLTMPRo-demo-resources" file to import these assets into your project.

How To Create Font Assets

You need to create font assets from font files to use them with TextMeshPro. Here are basic instructions for convenience. You can check out the official TextMeshPro documentation to learn more.

Open Window/TextMeshPro/Font Asset Creator window.

1. Assign your font in Font Source field (Your font must include your characters)
2. Set atlas size. For Arabic we recomment 512x512 and for Hebrew 128x128 as a minimum. A larger atlas will have better quality but larger size on disk.
3. Set Character Set to Unicode Range.
4. Copy character ranges from files under Assets/RTLTMPro/Ranges folder into Character Sequence (Hex).
   • Arabic letters are in ArabicLetters.txt file
   • Arabic digits are in ArabicDigits.txt file
   • Arabic tashkeel letter are in ArabicTashkeel.txt file.
   • All arabic characters are in ArabicAll.txt. Normally you would use this to create your font asset.
   • Hebrew letters are in HebrewLetters.txt.
5. Press Generate Font Atlas button and wait for it to generate the atlas.
6. Press Save TextMeshPro Font Asset and save the font asset.

Usage Description

• Use GameObject/UI/* - RTLTMP menu to create RTL UI elements. (Alternatively you can replace Text Mesh Pro UGUI components with RTL Text Mesh Pro)
• Assign your font asset Font Asset property in RTL Text Mesh Pro component
• Enter text in RTL TEXT INPUT BOX secion.

Farsi

When checked, English numbers will be converted to Farsi numbers. When unchecked, English numbers will be converted to Arabic numbers.

Preserve Numbers

When checked numbers will not be converted.

Force Fix

RTL Text Mesh Pro does not fix texts that start with English characters. Checking this checkbox forces RTL TextMeshPro to fix the text even when it starts with English character. Multiline English texts will have problem on components that have ForceFix checked.

Fix Tags

When checked, RTL Text Mesh Pro will try to fix rich text tags.

Known Issues

• Fixed in latest version. For older versions follow the steps below. We need to override the text property of TextMeshProUGUI. But the text property is not defined virtual. You need to manually make the property virtual.
  • Open TMP_Text.cs from TextMeshPro source code
  • add virtual keyword to text property.
    
  • Open RTLTextMeshPro.cs and uncomment the top line where it says //#define RTL_OVERRIDE
  • Now you can use InputFields and Dropdowns.
