Total noob qestion here i was having some dificulity finding an answer to my question.
i was trying to make a road in a tunnel.
i started by wanting to make a polygon by feeding the points 0,1,21,23 into addprim.

as such
int road1 = addprim(0;“poly”; points) For some reason the array i put here does not not apear 1,0,23,21.


Nothing happened. now i'm stuck.
also anny help with making some sort of for loop to automaticly add poligons to all the bottom surfaces whould be greatly apreciated.

Please submit your hip. There's not enough info, like how your wrangle node is set up, and how you created the array.

This function works fine for me and can do what your intending.

As for your vex problem you had some typos in the code
This should work:

addprim(0, “poly”, array(1,0,23,21));

But your approach does create “illegal” polygons if you connect the road that way and is highly dependent on the point order and on that subdivide.

Your wrangle is also set to primitives…so your going to get 32 of the same created primitive. Set it to detail mode for just one.

Also, you could use curlybraces, not saying it's better, just another option for you to know about:
int road1 = addprim(0,“poly”, {1,0,23,21});

ok so i'm switching to a new tactic for creating the tunnel so the points are lined up.
However i am having issues with creating a for each loop in vex. i can not figure it out for the life ofme.
I tried in vex and with a normal for each loop. i cant figure out how to do for each point in ID (or group.)

i whould greatly apreasiate anny help that can be offered.
