Thanks for posting this technique (Coughcough
stickycoughcough)
On paper, a tool called a 10 point divider could be used for this. The concept of a 10 point divider is that no matter how wide it is extended, each point still remains in the same proportion.

A proportional divider, which has only two points, could also be used, but a 10 point divider makes it a lot easier.
It would be awesome of some smart modder could introduce a 10 point divider (or any other number) in to the plotting tools in the game.
I *think* the game 688 attack sub had it (but it could have been Fast Attack, I get them confused sometime). So I know it is possible to code. Whether it can be coded in to SH3/4 is another story.
Your way of using the circle function is innovative and imaginative. Well done!
My only issue is trying to do these steps while the game is running. Remember I am not that smart.
Tools that will help the player implement these techniques in the game are what is needed when .. ahem.. newer versions of submarine simulators are being designed.
I will be trying your method of altering the speed of the submarine. That never occurred to me. It is counter intuitive. I have always tried NOT to alter my speed.


Thanks for setting me straight.
And much thanks for taking the time to put together a nice easy to follow PDF.
