How do I use create animated text in a JSON?

Goal: Make wavy/shaky/rainbow animated text via BBCode in a JSON.

I saw the Animated Spritefont Template and was attempting to use the BBCode in a JSON. I specifically want to animate certain words. However I think since I'm using tags in JSON and not calling it via conditions and actions like in the example, it's not working.

Anyone get something like this to work in a JSON?

Are you saying that BBcode tags don't work when you store them in JSON? Can you show your code and JSON contents?

Sure!

Here is a line from my JSON where I inserted the BBCode tag for wavy text from the template.

"line":"Hello to you in this example [offsetY=" & (sin(time * 300 + loopindex * 90) * 8) "] wavy text [/offsetY]."

You can't store loopindex or any expressions in JSON. Here's what I would do:

JSON:
{"line": "Hello to you in this example [offsetY=%] wavy text [/offsetY]."}


Action: 
Text Set text to replace(JSON.get("line"), "%", str(sin(time * 300 + loopindex * 90) * 8))

Thanks for the help! Trying this and getting an error. I've tried multiple ways of formatting but still getting a syntax error for that comma after the JSON.Get. Here is the syntax:

(JSON.Get("scene."& scene & ".dialogues." & currentTextIndex & ".line"), "%", str(sin(time * 300 + loopindex * 90) * 8))

You can't store loopindex or any expressions in JSON. Here's what I would do:

> JSON:
{"line": "Hello to you in this example [offsetY=%] wavy text [/offsetY]."}


Action: 
Text Set text to replace(JSON.get("line"), "%", str(sin(time * 300 + loopindex * 90) * 8))
