Thanks RGaal, much appreciated, have come to the conclusion I need to go away and learn more VEX!

Hi,
first post here! Have come from a long time in Maya but have been very slowly picking up bits of Houdini for a while now but still mostly clueless

My question is..
I have an object travelling along a curve with a pathdeform node and want to test the colour of the path curve point at the current animated position of the object traversing it (I coloured the path curve points black and white at different points along the curve) the objective is to emit new points from my travelling object only when the path points are coloured white.

I'm emitting points from a wrangle inside a solver node from point 0 of the object that travels along the curve. Not quite sure how I got this far to be honest but managed to google my way (and its probably not the way it should be done) but am properly stuck now!

I have a curvepos attribute from the pathdeform node thats updated through the animation, and am trying to fathom if it's possible to use that to find the point color currently under the object over the course of the animation so I can emit new points only when its coming back as white.

Hope that all makes some kind of sense.

P.
