<body onload="setInterval('t=new Date/1e3;R=(...z)=>`rgba(`+z;x=c.getContext`2d`;with(Math)eval($.value)',16)"><input id=$><p><canvas id=c>Try it out here!
- Your function is called every ~16 ms (roughly 60-ish times per second).
t- Current timestamp in seconds.sin- Shorthand forMath.sin.cos- Shorthand forMath.cos.tan- Shorthand forMath.tan.R- Function that generates rgba-strings, usage ex.:R(255, 255, 255, 0.5)c- A 300x150 canvas.x- A 2D context for that canvas.
- The canvas is the default size of 300 x 150 instead of 1920 x 1080.
requestAnimationFrameis not used, instead an approximation of 60-ish fps is achieved with a 16ms interval.tvariable is not a seconds counter starting from 0. Instead, it is the current timestamp in seconds.- Trig method shortcuts are
sincosandtaninstead ofSCandT. Bonus: AllMathmethods are available too! - Arguments passed to
Rare not optional and are not automatically converted to numbers. - 140 character limitation is not implemented (I had to scrap it to include the
R()function and stay under 140 bytes 😞)
- Special thanks to p01 for being my golf caddy on this.
