    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.

Number collector!! Click the screen to move the square 90 degrees clockwise. Collect the numbers. Don't crash into the edge of the screen or all your points will be lost. #interactive #game

Sorry, the square moves anti-clockwise when you click

#circlechallenge (no sine/cosine)

u/donbright

does fillrect have 6 parameters here?
u/cantelope

heh. it only looks at the first 4. i'm not actually saving any space by including 6 parameters, but why not? :)
u/cantelope

can you see how this circle method works? there is an array with 4 elements, the first 2 being positions (x,y), and the last 2 being analogous to a vector (in physics) with magnitude and direction, or simply (velocity-x, velocity-y). The velocity vector is added to the position coordinates once per frame and is itself adjusted in a way to create a perfectly circular "orbit" about the origin. Interestingly, this approach can be extended into 3 or more dimensions, and involve, obviously, more than 2 bodies. 3-body orbital chaos can be very interesting and beautiful, e.g. https://code.dweet.net/full/2w8z
