    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.

u/DaSpider

ReferenceError: U is not defined
u/KilledByAPixel

how is this possible?
u/tomxor

All loaded iframes are enumerated on the window object (for any webpage), the value is the window object of the corresponding frame... and from inside a dweet this can be accessed (with restrictions) by going to the parent frame, then you have access to any globals in that other frame. While you can't call a function since it's in a different JS context, you can read it's source and re-evaluate it.
u/tomxor

essentually window.parent[n].u is the function created by dwitter for dweet n on the page, if you add it to a string it calls toString which returns the source, you can eval this and assign it to something to run in this context.
u/tomxor

I think I am the most verbose person here sorry :/

u/rodrigo.siqueira

The game is great! Sound effects could also be generated in pure JS.
u/KilledByAPixel

Thank you! I released a tiny JS sound effect generator that I use for all my stuff. But couldn't fit it in this. https://github.com/KilledByAPixel/ZzFX
u/rodrigo.siqueira

Great JS sound effect library!! I'm playing a lot with it. If you put a Math.ceil around your main frequency (Math.cos), it will convert to square wave and sound like 8bit videogames. See here how it sounds: https://js.do/rsiqueira/audio-zzfx-square-wa…
u/rodrigo.siqueira

May be a small improvement that would bring good results would be to have "exponetial decay" option. And some sounds should not have decay (I implemented a simple decay_flag, if 0 there is no decay). Or may be it can be more generic, using the ADSR envelope model (Attack, Decay, Sustain, Release variables). I'm also trying to play a sequence of notes but the setTimeout for each sound/note does not bring reliable results.
u/KilledByAPixel

thanks rodrigo, i am planning on working on it more and adding a few more params, I want to keep it simple so still deciding!
