So, I modified it a bit, and wrote a ‘basic spherical fish AI’. This is the default player level with 500 fish in the playing area ( I used fog for the sea ):
I’m getting around 70-80 fps, ok… not great.
A lot really depends on your level, how dense you want the fish, etc.
I can defintely make if faster, and make a version that runs in unlimited space.
But tell me how you do first…
EDIT: 100 fps with another slight tweak…
