Simple Bullet Shadowing Surfer

Hi, I have an idea for a bullet shadowing wave surfer robot but I don't really know how to get started. Could someone point me to a relatively easy to understand wave surfer that implements bullet shadows into its danger prediction? Thanks in advance!

Implementing bullet shadow in wave surfer is very easy you just set danger covered by shadow to 0

however, calculating bullet shadow is not trivial

the first bot featuring this technique is Diamond, and it’s open source!

Just have a look at it, you’ll know that better.
