TextTyper is a text typing effect component for Unity. TextTyper prints out characters one by one to a uGUI Text component. Adapted by RedBlueGames from synchrok's GitHub project (https://github.com/synchrok/TypeText).

It's easy to find other examples of Text printing components, but TextTyper provides two major differences:

• Correct wrapping as characters are printed
• Support for Rich Text Tags

To start TextTyping all you need to do is add the TextTyper component to a unity Text widget:

1. Create a GameObject with a Unity UI Text Widget, as normal.
2. Add a TextTyper component to the GameObject.
3. Call the TextTyper component's public functions TypeText and Skip to print the desired text with the specified delay. We call these from a 3rd component we call Talker.

You can optionally subscribe to the PrintCompleted and CharacterPrinted UnityEvents to add additional feedback like sounds and paging widgets.

• Define Text Speed Per Character: Mayday! <delay=0.05>S.O.S.</delay>
• Support for uGUI Rich Text Tags: <b>,<i>,<size>,<color>,...
• Additional delay for punctuation
• Skip to end
• OnComplete Callback
• OnCharacterPrinted Callback (for audio)

The core of our text typer is a coroutine that’s triggered via the TypeText method. The coroutine has the following steps: Check next character to see if it’s the start of a Rich Text tag

• If It’s a tag, parse it and apply it. Right now “applying” a tag just means modifying the print delay, but other tags could be added. Add it to a list of tags that need to be closed (because we have not yet reached the corresponding closing tag in our string). Move to next character and repeat
• If it’s not a tag, print it
• Wait for the print delay
• Check if we are complete

The tool also uses RichTextTag.cs, a class that’s used to help with parsing. There are a few details I left out, but this should give you enough to start reading through the code if you want to know more.

The easiest way to help with the project is to just to use it! As you use it, you can submit bugs and feature requests through GitHub issues.
