Unity Standard Assets – CrossPlatformInputのモバイルスティックが、次のシーン読み込みで動かない問題解決

UnityのStandard Assets – CrossPlatformInputのモバイルスティックが、次のシーンを読み込んだあと動かない場合があったので、以下の方法で解決。

• Standard Assets/CrossPlatformInput/Scripts/Joystick.CSを、以下の部分を修正。

void CreateVirtualAxes()
{
    // set axes to use
    m_UseX = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyHorizontal);
    m_UseY = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyVertical);

    // create new axes based on axes to use
    if (m_UseX)
    {
        if (CrossPlatformInputManager.AxisExists(horizontalAxisName)) {
            CrossPlatformInputManager.UnRegisterVirtualAxis(horizontalAxisName);
        }
        m_HorizontalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(horizontalAxisName);
        CrossPlatformInputManager.RegisterVirtualAxis(m_HorizontalVirtualAxis);
    }
    if (m_UseY)
    {
        if (CrossPlatformInputManager.AxisExists(verticalAxisName)) {
            CrossPlatformInputManager.UnRegisterVirtualAxis(verticalAxisName);
        }
        m_VerticalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(verticalAxisName);
        CrossPlatformInputManager.RegisterVirtualAxis(m_VerticalVirtualAxis);
    }
}
