I would like to know when a new text is set on a TextMeshPro component. Is there a builtin way?
I want this so that I can modify the text right before it’s displayed on a separate component.
There is an ON_TEXT_CHANGED which is called when the text object is changed. See example scene 23 - Animating Vertex Attributes and the VertexJitter.cs script. These are both included in the TMP Examples & Extras.
This callback occurs when the text has changed and been processed whereas I think you want a callback when the string has been changed perhaps?
At any rate see if that callback works for your needs.
