我在我的第一个 Cocos2D 游戏中使用加速度计，它工作正常，我可以使用下面的代码移动精灵但是，当我将方向从 LandscapeLeft 更改为 LandscapeRight 时，精灵停止响应 Y 坐标，并且精灵转到屏幕顶部并且没有正确响应...我相信这是因为更改了设备方向，但我不确定，因为我对应用程序开发很陌生，任何帮助将不胜感激。

这是我正在使用的示例代码...

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration
{    
    //this determines how sensitive the accelerometer reacts (higher = more sensitive)
    NSUserDefaults *defaulObj = [NSUserDefaults standardUserDefaults];
    float sensitivity = [defaulObj floatForKey:@"Sensitivity"]; //10.0f
    if (!sensitivity) {
        sensitivity = 6;
    }

    // this controls how quickly the velocity decelerates (lower = quicker to change direction)
    float deceleration = 0.4f;
    static float xVal = 0;

    if (!self.isFlag) {
        xVal = -acceleration.x;
        self.isFlag = TRUE;
    }

    playerVelocity.x = playerVelocity.x * deceleration + (xVal + acceleration.x) * sensitivity;
    playerVelocity.y = playerVelocity.y * deceleration + acceleration.y * sensitivity;
    playerVelocity.y = playerVelocity.y*-1;
}

也许这会有所帮助，沿您当前的设备方向翻转 Y。

float rotatedY = acceleration.y;
if ([UIApplication sharedApplication].statusBarOrientation==UIInterfaceOrientationLandscapeLeft) {
rotatedY *= -1;
}

然后使用rotatedY代替acceleration.y
