Option for a Glowing Layer on an Entity

This COULD be considered a feature request, but I honestly just don't know where to post this kind of problem.

 So I'm new to this site, not really MCreator. I used it back in my early high school years, and with the Quarantine, decided to hop back on almost after 5 or so years. The program has come a LONG way from what I remember, its really quite amazing.

Anyway, I'm trying something I think would interest everyone. I want most of the mobs in my mod to have a layer, or a glowing texture. To do this, I found the Spiders layer properties, tweeked the code to match the names of my creation, and imported it into Mcreator's built in code. The problem is....I don't know how to Java haha. I don't really understand the errors it gave me (such as: not a statement, illegal start of expression, etc.), and honestly I would like some help trying to fix this, so in the future, this fix could help everyone get that glowing effect some mobs like Spiders, and Endermen have in game. Besides the unusual name given to my ideas, everything else is literally copy/paste from Minecrafts original code, with some minor tweeks here and there to what I thought made sense, but again...I'm not a coder, I like the visual side of Minecraft, the technical side isn't my forte..

Anywho, here is the locked code from the specific entity, hope someone can help with this. This wouldn't only help me, but the whole community to figure out how to accomplish this feature. Thanks in advance :)
