assigning / usage of NULL in script?

chrom

I built a walk through a node-parent-path to the root  in a while loop

while (camsParent)

                camsParent = camsParent.getNodeParent();

 

In some cases I want to stop it  manually and use

camsParent = NULL;

 

because of the description of getNodeParent  "The parent of this node in the scene hierarchy, NULL if this node is at root level."

 

But I get the error:     ReferenceError: Can't find variable: NULL

 

What is my mistakee and how can I fix it?

the correct syntax is

 

camsParent = null; //All lowercase

chrom

:)

thanks!

You might want to edit the first post and chnage the forum to the Daz Script Developer forum https://www.daz3d.com/forums/categories/daz-script-developer-discussion

I'm not sur what you are doing - you don't make a node the root of a hierarchy by setting its parent to null, if it's the root getNodeParent() will return null. If you want to unparent it you use removeNodeChild( child ) on the parent.

Ha ha, found the C programmer...

":)" meant I checked it and it was the solution. 

I just wanted a manually forced loop exit by the current loop check/condition

Yes and no. 

I only read the DAZ spec and there always mentioned "NULL"

The docs were probably written by their C++ programmers who were forced to write the JS documentation :)

If the APIs are the same then the docs get repurposed.
