Interactive buttons for 3D animation & java scripts

[vinothk92107740]

Hello all,
I created 3D animation pdf. I need to add buttons like play, pause, reset animation, play next step,play previous step.
I dont have much knowledge in java script. this is the first time im creating some scripts with help of google...

Somehow,successfully i created for Play and Pause animation but i got struck with remaining buttons.

var annot = getAnnots3D(0)[0];
annot.context3D.runtime.play();
If anyone familiar with this Scripts please let me know

and i have another query also , when ever i open the 3D pdf ,it started playing automatically.

 

This is my settings, how to stop automatically playing animation , I tried all the option from the above setting file.
Thanks in advance.
