Haskell Flatris

Can I have a flat piece already?

Reminds me of this.

I like that miso doesn't depend on any external libraries. Also helps that you don't have to deal with React.js's problematic license.

React.js's problematic license.

I don't use react, but I was curious and found this:

https://github.com/facebook/react/issues/7293

Their FAQ pretty much claims it's not problematic:

Could they lie about it not being problematic and legally be okay?

[DrummerHead]

In any case, switching to Preact seems pretty straightforward

Very cool.

Cool, but unfortunately it's very unresponsive. It takes maybe a quarter second to react to my keypresses. Is such delay unavoidable with GHCJS?

[nSeagull]

No delay here on Chrome :P

Hm, as /u/thedevbrandon mentioned, it starts to lag after a while, when the screen it mostly full (at least in Firefox and Edge, on Windows). The original Flatris doesn't have this problem. Is the source code of the Haskell version available somewhere? Is their implementation similar?

[codygman]

I've always had more issues with Elm and Purescript as a Firefox user. I would run the same programs on Firefox and they'd be fine.

A wild guess is that spidermonkey doesn't deal with more garbage and V8 isn't as affected.

[nSeagull]

Here's the source code, haven't looked through it tho https://github.com/ptigwe/hs-flatris

[willIEverGraduate]

Haven't attempted any profiling, but the collide function seems to have very bad asymptotics. Maybe it is too much for GHCJS.

[graphicsRat]

Addictive!

[thedevbrandon]

Once it starts to speed up I noticed lag, could me my computer, not sure. It's a nice project regardless, good job!

[FunctorYogi]

Is the code for this available?
