it's cool that this works - this is grabbing a virtual state from another object.

I believe this function figures out what the yellow eco shots will "lock on" to.

This will iterate over all the spawned actors

This is the function that adjusts the path of the yellow eco shots if they need to go around something (if you shoot at a thing behind a small obstacle, the yellow eco will go around that obstacle)

this handles the case where you hit a special thing that kills the shot

Wow, another use of the extremely rare copy method!

are you sure arg0 is projectile? I think it might be entity.

I wonder what a projectile-blue is?

i think they are blue eco related, but im not 100% sure. I've found some in the game but can't remember where. shooting yellow eco is definitely an instance of projectile-yellow though.

all these weird shifts are a cool trick to wrap angles to +/- 180 degrees

this is interesting. This is code for some other projectile that plays the blue eco sound I guess?
