Digital Workshop

I would like to create an object which will spin randomly when clicked.
Something like the spinning arrow on various educational spinner wheels.

I see some examples of scripts like the following in various resources but I cannot figure out how to implement this in Opus.
Examples of spinner scripts:
on(press){
object.spinning = true
object.spin = 12 + Math.random()*20
object._rotation = object._rotation = 0
}

if (spinning){
if (spin <= 0){
spinning = false
rot = (_rotation < 0) ? 180 + _rotation : _rotation
_root.youSpunA = Math.floor(16 * rot/180)+1
}else{
_rotation += spin -= .25
_parent.wheel._rotation = -_rotation
}
}
}


Any help on this will be greatly appreciated.

This is rather advanced scripting. Unless you need something this complicated - you could use Opus actions.

See example. Click the spinner hand to spin.

Hi Mack,
This is perfect. Greatly appreciated. I hope to learn more scripting by following your example.
Thanks again.

Hi Mack,
Sorry to bother you again.
Your publication spins fine when in preview mode.
But when published to flash, spinner does not work. I am baffled and dont understand why.

I have also attached an imp file that I created using your as an example.

could you please help again.
Kind regards

That's because you've published to SWF. Most the functions in Opus are not available in Flash publications.

Mack

Thank you very much again Mack. That explains what was happening.

Maybe someone from digital workshop can offer some advice here. I use Promethean Activstudio in my classroom. So far all publications I made with Opus Pro were published to SWF . This worked great because I then could embed the output SWF files inside ActivStudio. This created a wonderful seamless learning environment.

The next best option when ouput to swf does not work is the standalone publication mode I guess where a single EXE file is generated and this can be embedded inside Promethean Activstudio.

Unfortunately htm file cannot be embedded in Activstudio. I even tried to save the htm file output as mht but that did not work.

This spinner should be SWF compatible.

Mack

Thanks again very much Mack.
yes indeed this does work in swf format.

I was looking through the two variables that you used.
I understand how the "myrandom" variable works with a max value of 4

I see that you also declared another variable called "mytick" which is set to -1.

But I do not understand how "myrandom" interacts with "mytick".

Could you help me understand how this all works so nicely?
Thanks again.

The myTick variable is control via a ticker action on the page. It increments 1 per second. The start button resets this and starts the count again until myRandom is reached which triggers the stop action.

Ignore this one - it posted twice!!
