manipulating vex group name?

[probiner]

How do I manipulate a group name? Here I'm onto grouping the corresponding points of similar mehes, so that I can then connect them.

I got it working but not for any situation, here it works for a cube with 8 points

int grpnum = @ptnum % 8;
@group_grp_0 = (grpnum == 0);
@group_grp_1 = (grpnum == 1);
@group_grp_2 = (grpnum == 2);
@group_grp_3 = (grpnum == 3);
@group_grp_4 = (grpnum == 4);
@group_grp_5 = (grpnum == 5);
@group_grp_6 = (grpnum == 6);
@group_grp_7 = (grpnum == 7);

So, I'm trying to do a version without explicit lines, just a loop for n points, not just 8.

 

int psize = 8;

int grpnum = @ptnum % psize;

for (int i = 0; i < psize; i++) {
@group_grp_i = (grpnum == i);
}

Where it says @group_grp_i, I would like 'i' to be the iteration value. As is, it just makes it all named grp_i, not grp_0, grp_1, grp_2.... etc.



Thanks!

no idea what I am doing, clutching at straws...I changed the for loop to

for (int i = 0; i < psize; i++) {
s@grp = sprintf("%s%d","grp_",grpnum);
}

results:

grp
===
grp_0
grp_1
grp_2

etc....etc...

Nah...pls ignore..I'm yet to fully understand the problem..

Thanks, that led me to the answer:

int psize = 8;
int grpnum = @ptnum % psize;
setpointgroup(0, sprintf("%s%d","grp_",grpnum), @ptnum, 1);

setpointgroup seems to be way to go!

Cheers

I'm back to annoy ppl...:) whatabout Partition, rule is:

grp_`@ptnum%8`

I learnt from this too...thanks

Just having a hard time to imoport the @numpt of another mesh. Doesn't seem to be a point attribute.  
I would like to have

int psize = 8;

with something like:
 

int psize point(1, "numpt", 0);

Where 1 a second input.

Below my attempt to get numpt from another mesh in VOPs. Always retuns 0. I expected 4. Dunno...

i@psize = npoints(1); should work  

Edit: Sorry if you want it in vops I guess an inline vop with $psize = npoints(1);
