启动一个计时器来控制就行了。
你要多少时间刷新一次，就用这个时间来设置计时器，计时器更改你的数据，然后刷新就行了。

void Object::Draw()
{
    // Do not draw if it should not be visible
    if ( !IsVisible() )
        return;

    iTick = m_pMainEngine->GetTime()/20; // 1 per 20ms
    int iFrame = iTick % 30;
    int iSize = 10 + iFrame;
    if ( iFrame > 15 )
        iSize = 10 + (30-iFrame);

    /*draw object*/

    // Store the position at which the object was last drawn
    // You MUST do this to ensure that the screen is updated when only drawing movable objects
    // This tells the system where to 'undraw' the object from
    StoreLastScreenPositionAndUpdateRect();
