HTML5/C++ Accelerometer differences

HTML5/C++ Accelerometer differences

#1

I was messing around the the HTML5 implementation of accelerometer events and as far as I could see, it does not seem to detect the current platform and perform key bindings for the events the same way the C++ version does.

Is this feature implemented anywhere and I just missed it, or is it really not there? If so, any reason why this is the case?

Thanks in advance!

In case someone is interested, this is how I got around this limitation:

First I added this method to a class that extends cc.Layer:

keysToAccelerometer:function(key){
    switch (key) {
        case cc.KEY.left:
            var accelEvent = {timestamp: new Date().getTime(), x: -0.2, y: 0, z: 0};
            this.onAccelerometer(accelEvent);
            break;
        case cc.KEY.right:
            var accelEvent = {timestamp: new Date().getTime(), x: 0.2, y: 0, z: 0};
            this.onAccelerometer(accelEvent);
            break;
        case cc.KEY.up:
            var accelEvent = {timestamp: new Date().getTime(), x: 0, y: 0.2, z: 0};
            this.onAccelerometer(accelEvent);
            break;
        case cc.KEY.down:
            var accelEvent = {timestamp: new Date().getTime(), x: 0, y: -0.2, z: 0};
            this.onAccelerometer(accelEvent);
            break;
        case cc.KEY.comma:
            var accelEvent = {timestamp: new Date().getTime(), x: 0, y: 0, z: 0.2};
            this.onAccelerometer(accelEvent);
            break;
        case cc.KEY.period:
            var accelEvent = {timestamp: new Date().getTime(), x: 0, y: 0, z: -0.2};
            this.onAccelerometer(accelEvent);
            break;
    }
}

And then, in my onKeyDown method, I add the following:

onKeyDown:function(key) {
    /* ... */
    this.keysToAccelerometer(key);
}

Not sure if this is a perfect solution, but it works pretty well for debugging purposes :slight_smile:

Cocos2d-html5 has implemented accelerometer in /cocos2d/platform/accelerometer.js.

There are also some accelerometer tests in test case/event tests.
