    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

Looks very nice and smart coded. One noob question: which colors will be used in the loop by default when you don't use fillStyle? I saw many examples without fillStyle but the result is not monochrom. Thx.
u/rep_movsd

The default fill color and stroke color are black. Colors have to be set with fillStyle, strokeStyle or perhaps even setting the background (rare)
u/pavel

The default color for fill, fillRect, stroke, strokeRect is black and you need to call fillStyle or strokeStyle respectively. You must have seen other drawing techniques, maybe like putImage or using style attributes to add a filter over the B&W colors.
u/pavel

Haha looks like we answered at the same time and eerily similarly.
u/UEZ

Hmm, when I look to https://www.dwitter.net/d/23732 I cannot see any strokeStyle/fillStyle but the color result is greyscale.
u/pavel

Gray can be achieved by spacing out black pixels amongst white ones. d/23773 shows this clearest.

Twisted metal remix #uncompressed

u/danny@hille.dk

This is a personal thing!!! Twister2d is one of my favorite old school effects, it's also one of the first things i tried to golf to fit into a dweet (and I failed miserably :-)) I have retried tried (and failed) a couple of times, but this is the first time i actually managed to get the damn thing to fit without compression. I had to scarifice colors to maintin an interesting animation. Perhaps I'll get it next time :-) #twister #twister2d
u/New_Core
