How to remove points based on their attributes in Houdini?

I created a curve with several points. Now I want to delete some points based on one of their attribute (will_be_removed).

geometry spreadsheet

As is shown in the picture above, those points with i@will_be_removed set to 1 will be removed.

I tried using the VEX code below but it said invalid subscript for type: int.will_be_removed

if(@ptnum.will_be_removed == 1)
{
    removepoint(0, @ptnum);
}

How can I correctly reference those points?

Solution

  • I think I figure out a way to do it. Use @will_be_removed instead of @ptnum.will_be_removed instead:

    if(@will_be_removed == 1)
{
    removepoint(0, @ptnum);
}
