Tutorial - Synchronizing Actions

There are 2 macro defined in Web Cartoon Maker to help you to synchronize actions. These are THIS_TIME and SAME_TIME. Some methods and functions like GoesTo () or Winks() and all Change...() methods and functions can change the current time in scene. For example a boy in the script below first moves to a new location and then raises his hand and then winks:

#include <boy.h>

void Scene1 ()
{
    Boy Max;
    Max.SetPos ( 300, 290 );
    Max.SetVisible ();

    Max.ChangePos ( -300, 290, 2 );
    Max.RightArm.ChangeAngle ( 65, 2 );
    Max.Winks ();
}

But what if we want these 3 things to happen together? You can use GetTime () and SetTime () of course:

#include <boy.h>

void Scene1 ()
{
    Boy Max;
    Max.SetPos ( 300, 290 );
    Max.SetVisible ();

    double dStartTime = GetTime ();

    Max.ChangePos ( -300, 290, 2 );
    SetTime ( dStartTime );
    Max.RightArm.ChangeAngle ( 65, 2 );
    SetTime ( dStartTime );
    Max.Winks ();
}

But it is not very convenient. There is a more convenient way to use THIS_TIME before first action and SAME_TIME before other actions happening at the same time:

#include <boy.h>

void Scene1 ()
{
    Boy Max;
    Max.SetPos ( 300, 290 );
    Max.SetVisible ();

    double dStartTime = GetTime ();

    THIS_TIME Max.ChangePos ( -300, 290, 2 );
    SAME_TIME Max.RightArm.ChangeAngle ( 65, 2 );
    SAME_TIME Max.Winks ();
}

At the end of this tutorial please compile the above script and preview it in WCM Player
