VEXing array question - SOLVED

[kev2 36]

Hi, 

If I use an attribute wrangle to create an array attribute and populate the array like so:

i[]@stuff = nearpoints (0, @ape, 1, 23);

I can then slice the array like so:

i@branch = @stuff[3];

and all is good in the world.

However, if I attach another wrangle node and try to use the same slice, I get an error even though the array attribute shows up in the spreadsheet? 

Not a showstopper but I'd love to know why the attribute isn't accessible.

I don't know why that doesn't work, but this seems to work:

i@the_slice = i[]@opinput0_stuff[3];

-b

Oh, nice trick Bonsak. Works for me too. I'll give this post a couple days and submit it to support if no one can explain it. Maybe its not supposed to for some reason.

And,

i@the-slice = i[]@stuff[3]; 

also works so it appears to need the [] prefix for the vex snippet to pick up an array attribute.

Good to know. Less typing

-b

if you don't declare the attribute type the first time you call it

it defaults to float

For completeness, all I needed to do was declare the array as itself: 

i[]@stuff = i[]stuff; 

and then it picks up the array so that i@branch = @stuff[4] works fine now. Thanks @david for the assist.
