"WARNING: ReferenceError: getNodeParent is not defined" for DzDistantLight::getNodeParent() ??

3dcheapskate · January 2015

I'm a little rusty since I haven't looked at any DAZ script for half a year. Here's a code snippet that's crashing my script...

   print("wbNode="+wbNode)
   print("wbGndNode="+wbGndNode)
   print("wbSunNode="+wbSunNode)
   print("wbIblNode="+wbIblNode)
   
   // Parent the sun to the worldball   (N.B. WORLDBALL + SUN NEED TO BE ZEROED FIRST !!! )
   var oParent=wbSunNode.getNodeParent();
   if (oParent && oParent!=wbNode){ // If the sun's already parented to anything except the worldball it must be unparented first
    oParent.removeNodeChild(wbSunNode); // no second parameter given (so inPlace=false)
   }

...and this is what ends up in the logfile when I run it in DS 3.1 ...

Line 1854 is the 'var oParent=wbSunNode.getNodeParent();'

But the debug shows that wbSunNode is a DzDistantLight, and getNodeParent() is a valid member function (inherited from DzNode).

So why's it telling me getNodeParent isn't defined?

What's the obvious thing I'm missing/overlooking?

Richard Haseltine · January 2015

I don't know - I copied your script, copied the name of your variable from the print statement to a var declaration to get the light and it works - with or without a semicolon after the print statement, which is the only thing leaping out as a fault in your code.

var wbSunNode = Scene.getPrimarySelection();
   print("wbSunNode="+wbSunNode)
   
   // Parent the sun to the worldball   (N.B. WORLDBALL + SUN NEED TO BE ZEROED FIRST !!! )
   var oParent=wbSunNode.getNodeParent();
   if (oParent){ // If the sun's already parented to anything except the worldball it must be unparented first
    oParent.removeNodeChild(wbSunNode); // no second parameter given (so inPlace=false)
   }

Thanks Richard, that's actually a good start. I copied your version of my snippet to a new test.dsa, selected a distant light, and ran the snippet (i.e. without the preceding 1850 or so lines of my original). Got this in DS 3.1...

I still haven't solved this, but I've run into another problem where a section of code works fine in isolation, but does something odd when it's part of the main 1600-or-so line script - "Update Prop Origin Only Working If I Display Message Boxes ???"

Although it's a different script, I'm wondering whether the root of the problem may lie somewhere in those other lines of code...

rbtwhiz · June 2015

In your snippet, "wbSunNode" is assumed to be a valid DzNode object. Don't assume. Make sure that it is not undefined/null. As written, if a node is not selected you will get that error, since you are then attempting to call getNodeParent on a null, not a DzNode object.

Agreed, I should check it's valid first (I wasn't checking). But if wbSunNode is undefined/null then why does the print statement earlier seem to indicate that it's valid?

Here's the chunk of code immediately preceding it (mainly for my own reference - I haven't looked at this for months):

        ...
        // ...we should now have exactly one of each. If not, I've messed up!
        if(aBalls.length==1 && aSuns.length==1 && aIbls.length==1 && aGnds.length==1){
        
            // Identify the WorldBall and WorldBall Ground nodes
            var wbNode = undefined;
            var wbGndNode = undefined;
            var wbSunNode = undefined;
            var wbIblNode = undefined;
            wbNode = this.getOurNode(allNodes[aBalls[0]].getLabel());
            wbGndNode = this.getOurNode(allNodes[aGnds[0]].getLabel());
            wbSunNode = this.getOurNode(allNodes[aSuns[0]].getLabel());
            wbIblNode = this.getOurNode(allNodes[aIbls[0]].getLabel());
            
            beginUndo(); // Causes a script error if any object is added/deleted between here and 'acceptUndo()'
   
   print("wbNode="+wbNode)
   print("wbGndNode="+wbGndNode)
   print("wbSunNode="+wbSunNode)
   print("wbIblNode="+wbIblNode)
   
   // Parent the sun to the worldball   (N.B. WORLDBALL + SUN NEED TO BE ZEROED FIRST !!! )
   var oParent=wbSunNode.getNodeParent();

3dcheapskate · July 2015

Adding the check makes no difference (or probably I've done the check wrongly - it's been so long since I wrote any DAZ script!) - it thinks wbSunNode is valid

   print("wbNode="+wbNode)
   print("wbGndNode="+wbGndNode)
   print("wbSunNode="+wbSunNode)
   print("wbIblNode="+wbIblNode)
   
   if (!wbSunNode){
    print("wbSunNode is NOT valid")
   }else{
    print("VALID wbSunNode")
    // Parent the sun to the worldball   (N.B. WORLDBALL + SUN NEED TO BE ZEROED FIRST !!! )
    var oParent=wbSunNode.getNodeParent();

And running that in DS 4.6 I get this

This smacks of self-screwing-up code! Which could explain why sometimes other odd things happen.

Richard Haseltine · July 2015

Try printing the className() for your objects - it looks as if they are there but not what you expect.

3dcheapskate · July 2015

Thanks Richard, just tried that and you're right - they're not nodes (and it's so obvious! Look where the 'getLabel()' is! )...

           ...
            wbNode = this.getOurNode(allNodes[aBalls[0]].getLabel());
            wbGndNode = this.getOurNode(allNodes[aGnds[0]].getLabel());
            wbSunNode = this.getOurNode(allNodes[aSuns[0]].getLabel());
            wbIblNode = this.getOurNode(allNodes[aIbls[0]].getLabel());
            
            beginUndo(); // Causes a script error if any object is added/deleted between here and 'acceptUndo()'
   
   print("wbNode="+wbNode+", className()="+wbNode.className())     // THIS IS LINE 1848
   print("wbGndNode="+wbGndNode+", className()="+wbGndNode.className())
   print("wbSunNode="+wbSunNode+", className()="+wbSunNode.className())

   if (wbSunNode == undefined){

   }else{
    print("wbSunNode seems OK")
    // Parent the sun to the worldball   (N.B. WORLDBALL + SUN NEED TO BE ZEROED FIRST !!! )
    var oParent=wbSunNode.getNodeParent();
    ...

...and got this...

Then I noticed that wbNode, wbSunNode etc are all strings, not nodes - they're set up with wbNode=xyz.getLabel()

I thought that this would explain things, but...

3dcheapskate · July 2015

...but here's the same section in the original version of the script (with an extra print to confirm the section of code is actually being run), which works. I've also added a comment to show where I inserted new code to crash it...

3dcheapskate · July 2015

The 'Apply worldball material bit at the end continues like this...

            // Apply the WorldBall material
            if (wbNode){
                this.m_oNode = wbNode[0];
                this.m_aMaterials = new Array;
                g_oPresetHelper.collectMaterials( this.m_oNode, false, false, false );
                this.m_aMaterials = g_oPresetHelper.getCollectedMaterials();
                
                oWb = this.m_oNode.getObject();

So in my origibal working version of the script this.m_oNode is being set as a single character, the first character of the label.

I'm surprised that g_oPresetHelper.collectMaterials() and/or getObject() don't crash ?

So wbNode was always intended to be a DzNode, not a string.
I therefore assumed that correcting the getLabel() bit would resolve things, but...

3dcheapskate · July 2015

If I remove the getLabel() then the script with inserted code no longer crashes. But it always does the 'wbSunNode is undefined' bit

        ...
        // ...we should now have exactly one of each. If not, I've messed up!

            wbSunNode = this.getOurNode(allNodes[aSuns[0]]);
            wbIblNode = this.getOurNode(allNodes[aIbls[0]]);

     oParent.removeNodeChild(wbSunNode); // no second parameter given (so inPlace=false)
    }
    if (!oParent){ // If the sun's not already parented to the worldball then parent it

    print("Applying worldball material")
                this.m_oNode = wbNode[0];

        // Regenerate the Worldball node counting arrays...
        aBalls = [];
        aSuns = [];
        aIbls = [];

        if(aBalls.length==1 && aSuns.length==1 && aIbls.length==1 && aGnds.length==1){

...or here...

Oh dear, I'm talking a load of rubbish here ! :oS
Did I say I'm a little rusty in the OP? More like totally seized up and in need of a good whack with a mallet! LOL

I'm not setting wbNode, etc to a string with xyz.getLabel() - I'm passing xyz.getLabel( as a parameter to getOurNode() , and setting wbNode to whatever that returns.

And although the function getOurNode() was in the original script it was never called till I inserted this new code...

3dcheapskate · July 2015

Finally ! And so stupid... as usual. getOurNode() is totally unnecessary :D

     // Identify the WorldBall and WorldBall Ground nodes
            var wbNode = undefined;
            var wbGndNode = undefined;
            var wbSunNode = undefined;
            var wbIblNode = undefined;
            wbNode = allNodes[aBalls[0]];
            wbGndNode = allNodes[aGnds[0]];
            wbSunNode = allNodes[aSuns[0]];
            wbIblNode = allNodes[aIbls[0]];
            
            beginUndo(); // Causes a script error if any object is added/deleted between here and 'acceptUndo()'
   
   if (wbSunNode == undefined){
    print("wbSunNode is undefined")
   }else{
    print("wbSunNode seems OK")
    ...

Now just got to find out what that oHand should be... I obviously just cut-and-pasted a chunk of code from my Smart+ Prop stuff.
