Why are there different running modes for the playhead?
The playhead can – automatically run forward – remain at a certain frame position – automaticall run backwards Usually in a presentation you want to change the shown slides manually. That is you want to click on a button or press a key to see the next/previous slide. This is the default case if you want to present content slides. However for animation effects it is sometimes usefull to automatically exchange the slides very fast: In this case the Javanti slides work like a film roll in a cinema. Because the content is exchanged so rapidly a constant movement of objects is seen by your eyes. For frame animation or keyframe animation an automatically exchange of the slides is need. Therefore the playhead can move automatically forward or backwards. You can change the run direction manually in the control panel. At runtime you can also change the run direction using the setRunDirection action. This allows you to switch between animation and normal presentation mode in the same Javanti pro
