Android游戏My Paper Plane是如何实现倾斜控制的一个很好的例子,但我一直在努力理解如何做类似的事情.

我有以下示例,它使用SensorManager中的getOrientation().整个事情都在这里的pastebin上.它只是将方向值打印到文本字段.这是最相关的片段:

private void computeOrientation() {
    if (SensorManager.getRotationMatrix(m_rotationMatrix, null,
                                        m_lastMagFields, m_lastAccels)) {
        SensorManager.getOrientation(m_rotationMatrix, m_orientation);

        /* 1 radian = 57.2957795 degrees */
        /* [0] : yaw, rotation around z axis
         * [1] : pitch, rotation around x axis
         * [2] : roll, rotation around y axis */
        float yaw = m_orientation[0] * 57.2957795f;
        float pitch = m_orientation[1] * 57.2957795f;
        float roll = m_orientation[2] * 57.2957795f;

        /* append returns an average of the last …
