matching values in a prim wrangle?

[alexisB]

I'm creating horizontal and vertical lines from geometry,

and testing whether a horizontal line has a matching position in x as one of many vertical lines.

If not, it's not "supported" by a vertical post, and therefore should be deleted.

 

When I test it with a grid with lines copied to its points, it works fine.

But creating the lines from a points from volume SOP,

the prim wrangle is returning the wrong values,

deleting way more than it should.

 

I am hoping someone could point out why it would work in one case and not the other,

when the geometry I'm feeding in seems pretty comparable.

I think the code that is having issues is in my prim wrangle near the bottom:

 

------------------------------

int colCount = nprimitives(1);

float match;

 

for (int i=0; i<colCount; i++){

 

   match = prim(1,"xPos",i);

   

   if (@xPos == match){

   @die = 0;

   }

   

}

---------------------------------

 

 

Kinda hard to explain with words... file is attached

 

Anyone have any ideas?
