Has anyone tried to use impactjs to make a Kindle Fire project yet? I'm using Phonegap, developing inside the Eclipse IDE. Ignoring the tragedy of attempting to implement sound there for the moment, it's just running insanely slow.

I am able to get an app to run in the emulator, and after having stripped down all the functionality so that I'm doing nothing more than displaying a row of buttons on the background screen. I did this, because on my firs attempt, the game had more functionality, and it was taking several seconds for any response to occur after a button press. But even stripping everything out, so all it contains is the bare-bones impact engine, a background image, and a row of buttons, it is astonishing how slow the response is. I click a button on my UI, and it takes upwards of 1/2 a second to get a response. There's no functionality in the game at all. It is just set up to change the mouse button image when clicked.

Perhaps I'm doing something dramatically wrong, because as it stands, I can't see how the Kindle could possibly run any Javascript app.

(Oh, and before anyone asks, I did try running the stripped down app on the kindle, and it's still noticeably laggy).

Anyone have any examples of ImpactJS applications running on the Kindle Fire, just to give me some hope here?

I'm pretty sure if you convert your impact game into a .apk file it would work on the Kindle Fire market, I don't know how to get it in the market, but the Kindle Fire (from my experience) downloads .apk files and runs them. To turn your game into an .apk file all you have to do is use a service like CocoonJS or Appmobi.

Basically all you have to do is turn your game into an .apk file, then post the game in Google play/ The Android Market then you can distribute the app through the Amazon mobile app service. This is what the FAQ on Amazon says.


Q: My app is currently for sale on Google Play. Can I submit it for the Amazon Mobile App Distribution Program?

Yes, the Amazon Mobile App Distribution Agreement is non-exclusive.

Also your going to have to configure the game to the devices screen size. Don't forget that.

In regards to your performance issues the canvas performance for android or really any mobile device is just terrible. That's why you're seeing it run so slow. My game running as a stock web-app runs at like 12 FPS on my Transformer Prime. Once I used ejecta or AppMobi it immediately jumped back to the 60 FPS that I'd expect. You're going to have to use a project like that to get the performance you seek.
