Connecting Scripted Ops

[5quid]

I don't think you are doing anything wrong. i've had this crash on even the simplest of scops saved to spdl...so much so, that i never, ever save scops as spdls now.

If you desperately need this intersection scop i'd suggest wrapping it into an apply script (or if you wait till tommorrow, i can do it for you) and using it that way.

You can rewrite it to be applied by running a script, there are examples in the sdk how to do so.

Take everything in update code and in sub pane as well and make the into a function:

function YouOp_Update (ctx, Out, InNullKine, InPolymsh, InP0Kine, InP1Kine, InPolymshKine) {
Copied code goes here
}

Then:

// Create new scripted operator
oScop = XSIFactory.CreateScriptedOp ("YouOp", "", "JScript");

// Add inputs and outputs
oScop.AddOutputPort (connection.FullName);
oScop.AddInputPort (connection.FullName, "portname");

// Add parameters
oScop.AddParameter (XSIFactory.CreateParamDef2 ("text", siString, "hello"));

// Convert update function to string
codeStr = YouOp_Update.toString();

// Add code and connect operator
oScop.Code = codeStr;
oScop.Connect ();

This should get you started!
Feel free to ask if you've got more questions.

Thanks for the assistance guys.

5quid... Reading through the SDK makes me think that I was doing something wrong, but at this point it's way above me... only so much mental bandwidth right now. If you do get a chance tomorrow, that would be much appreciated.

ShadowM8... I have tried to do so and follow the SDK examples that I could locate. I keep getting an error:

//ERROR : 'connection' is undefined

I've looked through the code to see if it was a simple typo error or something, but I'm not really versed well enough in the API or jscript to troubleshoot it effectively. Any thoughts on why the error is being thrown?

[ShadowM8]

Well I poseted the example so no need for sdk other than to check on methods, you pretty much just need to fill the blanks :)

If you have specified an output connection correctly you should be able to connect the operator without a problem. In this case
oScop.AddOutputPort (Arrow.Kinematics.Global.FullName);

Here's the script for you!
Obviously you'd need to change naming as required for your scene.


// Create new scripted operator
oScop = XSIFactory.CreateScriptedOp ("Op", "", "JScript");

// Add inputs and outputs
oScop.AddOutputPort (Dictionary.GetObject("arrow").Kinematics.Global.FullName);
oScop.AddInputPort (Dictionary.GetObject("arrow").Kinematics.Global.FullName, "InNullKine");
oScop.AddInputPort (Dictionary.GetObject("grid").ActivePrimitive.FullName, "InPolymsh");
oScop.AddInputPort (Dictionary.GetObject("start").Kinematics.Global.FullName, "InP0Kine");
oScop.AddInputPort (Dictionary.GetObject("end").Kinematics.Global.FullName, "InP1Kine");
oScop.AddInputPort (Dictionary.GetObject("grid").Kinematics.Global.FullName, "InPolymshKine");

// Add parameters
var param = oScop.AddParameter (XSIFactory.CreateParamDef2 ("NormalOrient", siBool, true));
var param = oScop.AddParameter (XSIFactory.CreateParamDef2 ("Roll", siDouble, 0, 0, 360));

// Convert update function to string
codeStr = Op_Update.toString();

// Add code and connect operator
oScop.Code = codeStr;
oScop.Connect ();

function Op_Update (ctx, Out, InNullKine, InPolymsh, InP0Kine, InP1Kine, InPolymshKine) {
var geo = InPolymsh.Value.Geometry;

Thanks mate... I'll give it a go in a little while. :bounce:

[JDex]

Works like a charm... just had to remove some unneeded spaces from lines 103 and 105. Thanks alot man. Now I just gotta talk the boss into making me available for some R&D time for getting back into my scripting studies.

Once again, thanks ShadowM8

[ShadowM8]

You're welcome!

I was gazumped!
