Hi,
First post here since I start learning Houdini 3 weeks ago.
I'm trying to build vex code in an attribute wrangler node and I face some issues that perhaps you could help.

Input of my vex code is an object with primitive, wrangler node set to primitive.
I'm trying to randomly set an attribute (lets say i@electedPrimitive) to 0 or 1 with one constraint.
Constraint is 2 “connected” primitive couldn't be set to 1.

I have a function that return the “connected” primitive list of a specific primitive

So basically I have a var randomly set to 0 or 1
If 1, I get all “connected” primitive and count their electedPrimitive attribute.
If different from 0 then at least one of my “connected” primitive has been elected so I change the var to 0
In every situation, I store the var value in the electedPrimitive attribute.

Since this easy task did not work I'm wondering if I could change the electedPrimitive attribute on primitive 10 and read the attribute from primitive 10 on primitive 20 (10 & 20 are just example of course)

My guess is that primitive value are some kind of lock until the end of node.
Perhaps this is due to multitasking ?

Any advise ? solution ?
regards
FRED

sounds like you are trying implement a graph coloring algorithm. I'm not familiar with the proper solution, but perhaps this can get you started on finding one:

John, you should change your icon to a paperclip
