vex groups from string parameter

[bonassus]

If I have a string parameter assigned to each point of an object can I create a group for each point using it?

s@s = sprintf("%i",i@ptnum);
f@group_s = @s ???

thanks,

string s = sprintf("point_%d",@ptnum);
setpointgroup(0, s, @ptnum, 1);

Okay, thanks a lot. I see now in the help card that the last parameter, 1 is a value parameter. Is this a true false value?

Yes, you could do something like:

int grp = @Cd.r > 0.5; // returns 1 if red color above 0.5, 0 if 0.5 or less
setpointgroup(0, "red_group", @ptnum, grp, "set"); // sets group if grp is 1

Thank you, did you leave out the point number parameter from your example?
