u(t) is called 60 times per second.
t: Elapsed time in seconds.
S: Shorthand for Math.sin.
C: Shorthand for Math.cos.
T: Shorthand for Math.tan.
R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
c: A 1920x1080 canvas.
x: A 2D context for that canvas.
Intended for not-fullscreen on desktop. Add this to visualize the ducks' hitboxes x.fillStyle=R(255,0,0,0.5) for(i=c.width;i--;)for(j=c.height;j--;)(i-X-3)**2+(j-Y+3)**2>>8?0:x.fillRect(i,j,1,1)
