setpointattrib vex not working

[MadMax50]

Hello,I am trying to set a point attribute based on the points that the nearpoints function found. This gives me an error. I am not sure why. Any help would be appreciated , thank you

i[]@neigh= nearpoints(1,@P, chf("Max"));

int setpointattrib(0,"start", i[]@neigh, 1, "set");

setpointattrib.hipnc

You don't have to use a setpointattrib on input 0, because you're already running over those points. You can assign the attribute directly.

i@start = @neigh[1];

@Atom, thank you

As @Atom mentioned, you don't have to use setpointattib in this case. But just for completeness, it was erroring because the order of arguments is wrong and you included the return type in the function call. It should be like this:

setpointattrib ( 0,"start", @ptnum, i[]@neigh );
