Cocos2d-x iPhone6 和 iPhone X 中的加速度计 x y 互换

Cocos2d-x Accelerometer x y interchanged in iPhone6 and iPhoneX

在 iPhoneX 中完美运行。在 iPhone6 中,当我在横向模式下倾斜时,加速度计值甚至在纵向游戏中也会出现。如何获得纵向倾斜的加速度计值?游戏是纵向的。但是加速度计把它当作风景..

代码如下:

    Device::setAccelerometerEnabled(true);

    mAccelerometerListener = EventListenerAcceleration::create(CC_CALLBACK_2( GBGameScene::onAcceleration, this));
    _eventDispatcher->addEventListenerWithSceneGraphPriority(mAccelerometerListener, this);

加速度计代码:

void GBGameScene::onAcceleration(Acceleration* acc, Event* event)
{
    //  Processing logic here

    float deceleration = 1.0f;
    float maxVelocity = 100;

    playerVelocity.x = playerVelocity.x * deceleration + acc->x;
    playerVelocity.y = playerVelocity.y * deceleration + acc->y;

    if (playerVelocity.x > maxVelocity)
    {
        playerVelocity.x = maxVelocity;
    }
    else if (playerVelocity.x < -maxVelocity)
    {
        playerVelocity.x = -maxVelocity;
    }


    if (playerVelocity.y > maxVelocity)
    {
        playerVelocity.y = maxVelocity;
    }
    else if (playerVelocity.y < -maxVelocity)
    {
        playerVelocity.y = -maxVelocity;
    }

//    Point pos = mGravityBall->getPosition();
//    pos.x += playerVelocity.x;
//    mGravityBall->setPosition(pos);

}

我认为代码没有问题,因为它在 iphoneX 中运行完美。为什么不倾斜 iPhone6?

加速度计API沿固定轴运行。如果您想将其视为始终处于横向状态,则需要改用 y 轴。
