TextMesh Pro <action> Tag MextMeshPro

I have been looking at how I can implement custom tags into TextMeshPro. I came across the forum. I looked around and found a thread that there is a tag called <action>. The thread was posted in 2018, so I thought I could find some documentation, and I found none. I decided to put <action> into a TextMeshProUGUI component, it disappears like all other rich text tags.

So I am wondering, is this still a feature? How can I use this? Finally, is the tag still in TMPro as a mistake?

This <action> tag seems very powerful. And it reminds me of the custom commands in Yarn Spinner.

Thank you for reading.


I also have some other tag ideas if you want,

• Code (csharp):

  1. <wave height=float speed=float>
  This will create a wavy text effect used in many games.
• Code (csharp):

  1. <shake intensity=float>
  This will make the text shake and jitter around in random directions, also a popular effect in games.
