PhoneGap游戏，画布和缓慢的javascript [英] PhoneGap games, canvas and slow javascript

问题描述

所以我建立了我希望会成为一个简单的安卓游戏。我首先创建了一个网络版本（ http://scolvin.com/ballgame ），然后将其移至PhoneGap和使用加速度计来控制游戏。唯一的问题（它是一个显示停止问题）是结果是可怕的慢（更新我猜一次一秒钟，而不是20ms ish）。

只是怎么慢phonegap是，没有当前的解决方案？

这个游戏使用easeljs和box2d-web。

奇怪的是，它似乎在Android Chrome上以合理的速度运行，但是在Android的浏览器（我似乎记得是基于firefox？）和phonegap很可能使用相同的html renderer / js中断。 / p>

我已经尝试简化游戏，尽可能多地使用 setInterval ，而不是<$

解决方案

这是Android的问题浏览器

（这是Sencha Touch，点的答案是一样的）

So I built what I hoped would become a simple android game. I first built a web version to getting it working (http://scolvin.com/ballgame) then moved it to PhoneGap and used accelerometers to control the game. The only problem (and it's a show stopping problem) is that the result is horrifically slow (updates i guess about once a second instead of ever 20ms ish).

Is this just how slow phonegap is, with no current solution? Or is there some golden bullet I'm missing?

The game uses easeljs and box2d-web.

What's odd is it seems to run at a reasonable speed on android chrome, but very slow on android's "browser" (which I seem to recall is based on firefox?) and in phonegap which presumably uses the same html renderer/js interrupter.

I've tried simplifying the game, getting rid of as much as i can, using setInterval rather than accelerometer.watchAcceleration all to no avail.

解决方案

It's a problem of the Android Browser
