Scripted operator help

[JDex]

I've had a bit of trouble myself Sam. Chrystia and I were trying to find them in the SDK guides, but all we found we're "Custom" Operators, which were tagged as deprecated... she looked down that path, but I didn't get an update from her on whether they we're adequate for learning scops... she had to go away for the holiday.

See if Custom Operators can help get you started... and hopefully someone else can chime in and point us all in the right direction.

Thanks Jdex!

It almost seems that this is so easy that this part doesn't need to be explained and I the only person who can't figure it out. :banghead: (http://forums.cgsociety.org/misc.php?do=getsmilies&wysiwyg=1&forumid=0#)

assuming you have a scop connected like :

Outlocal | Out | cube.kine.local
Inlocal | In | null.kine.local


function Update(In_UpdateContext, Out, Inlocal){

// storing the kinematics property
var inY = Inlocal.Value.posy

// the variable name is only needed when there are multiple outputs
// otherwise we use the 'Out' var passed into the function as is
Out.Value.rotz.Value = inY.Value

}



doesn't get much more simple than this :)

And note that the custom op docs are still perfectly fine. What's been deprecated is the part that deals with installing SCOPs, that has been replaced by self installing plugins.

Scripted operators are documented in the User Guides (in the TOC, Customization > Scripted Operators).

One way to find out what you're dealing with is to simply log the classnames of the objects passed into the Update function:

LogMessage( classname( Inlocal ) );
LogMessage( classname( Inlocal.Value ) );
LogMessage( classname( Out.Value ) );

Thanks Guys!

As usual, I was trying ot overcomplicate things.

Basically, to get the value of the "in" named Inposy (which is Cylinder.kine.local.posy) all I need to do is use inposy.value. To assign that to the out (named outposy) I just use out.value = inposy.value.

doesn't get much simplier, but it can get less risky.
if you have an output value, you should also marshall a call to that value as an input, regardless of whether you intend to use that input value or not, this is meant to make sure that execution is correct and dirtyness is flagged on updates.

And if the question would have been : "please explain the subtle intricacy's of xsi's scene graph evaluation cycle" then maybe my example would have been less 'risky'.

but it wasn't, so i didn't.

:P

It's never to early to make sure the next question won't be "why does my scop fail to update unless I tweak some off unrelated value?" :p

Fair point :)

It's also never to early to mention that writing scops will ruin even the gentlest of dispositions.

compulsory calls marshalling, also known as "WTF?!", wrecked more families then the 2nd world war.
true story!
