Could someone please explain the following code to me in detail? I'm especially
confused by the
{} brackets.

k=player --1 or 2
cen={{120,360},{520,360}},     -- centers of clock
r=100,     -- radius of clock
rt=remaining time in secs



Don Cole
 
function p2xy(atom r, atom a)   -- polar to xy
   return {-r*sin(a),-r*cos(a)}
end function

draw_line(colors[k],{cen[[k],cen[k]+p2xy(r,rt/1800*PI)})

This code comes from       : Simple Chess Clock / Countdown Timer
