(Solved, ig??) How to make vanilla items unbreakable

Hi,

I'm making a minecraft rebalancing mod, and I've decided I'm gonna remove all durability from the game. At the time it sounded like a wonderful idea, until I realized how hard this actually is. Now I'm not a programmer, (thats why I use MCreator), so this seemingly simple task became an absolute pain in the rear end. I've found a temporary, unoptimized, "this is a problem for future me" type """"solution"""", which is just set every item's durability in every entity's inventory to 0 each tick.

With all that said, how in the living hell am I supposed to do this properly. (I'd be really happy if there was a solution not requiring me actually learning any programming language, but at this point if I even get a reply saying something like "erm, thats a problem with me too" or "sorry kid, go and learn how to make a   r  e  a  l   minecraft mod" I'm happy)

Thanks in advance!
