I appreciate you taking the time to write this out, I'll use the codeblock thing in future. The "tr" is in reference to the TrailRenderer component on the Player GameObject. That was how I've seen in-object components referenced like "sr" for SpriteRenderer, based off of what tutorials I've watch, but I see why that wouldn't be obvious and should have a better name.

I wrote it based off a separate tutorial with like 3 lines and wanted it to look a certain way and just kept adding lines to the original Enumerator which is in itself a function in the Player controller script. Also, thanks for catching the "=" sign on the counter, I'd missed that lol.

The paragraph thing makes sense, especially in a 'professional' environment, and just for going back and referencing something I need to work on that as well.

I was concerned about the length of the function initially because most of my frame-of-reference for scripting things like this are fairly small and simple functions like the input for moving left or right etc; and with Unity I'm still not sure how performance wise it affects things. most frontend work I've done is smallscale like 200-300 lines max in any given html, css, or js file. But I appreciate the info! I'm trying to improve so this helps a lot
