Basically a spiral configurable projectile trails plugin which works on the x y z axis all together(that's the tuff part i feel you...), 1.8, to 1.16.5... i know it's possible since i'm a dev too..., and i just couldn't figure that out, you can send the src no .jar needed..., ill be paying 50$ for this, add me on discord UseRod#4597

You're probably one of the worst quote-unquote "devs" out there, but either way, I'll spoonfeed you this one so you don't end up scamming someone for $50.

Assuming this is what you want, create a Runnable which runs per tick up until the projectile disappears, and for the z coordinate in my plane, simply increase it by theta. Afterwards, each tick, increase theta by pi/20.
Basically, your spiral is gonna have coordinates:
x = Rsin(θ), y = Rcos(θ) and z = θ (in my plane), therefore, to translate them in Minecraft, you get:
x = Rsin(θ), z = Rcos(θ), y = θ.
In order to tilt the spiral to some degree, it is a bit harder if you're completely uncapable of understanding maths, but you'll have to use the Rotation Matrix around a certain plane:

Therefore, in the end, you will get this:
