question about llDetectedTouchUV

Hi,

i'm making a hud which will be just chating the "buttons" will this work. in the notes for this it says

if you're using a single prim hud then yes, if you're using multiple prims for the buttons you'll need to use llDetectedLinkNumber, and if you have multiple buttons per face per prim, you would use them together, just make sure you get the logic right so it knows exactly which button you are pressing

it's a multi prim hud
each prim is a "page" with a different texture and different options.

however i just figured out a problem that makes it not viable.
the prims overlap and even if you want to click one the "last page" you'll click the first.

back to the sandbox

you could use 1 prim really, twist a cube, and stretch it so you see 2 full faces at once. and each face will be a page. as you flip thru the pages have the script keep track of which pages it's showing, when you click a "button" it can calculate where you touched:

gridspot# + (page#* #buttons on page) = button number

this can get tricky though if you don't always have the same number of buttons on each page

think i figured it.
path cutting a prim aka door.

in the script to hide the page also cut it to shrink it.

now i just have to work on the TouchUV coding & images.

with this function correct me if i'm wrong is this how it works and then to make it do something:

1. detect touch (vector)
2. store vector in Var
3. absolute ****load of IF statements (one for each button)

If the buttons are lined up in neat rows and columns you could write a function that returns a button number from the coordinates, which would make the shedload of ifs slightly easier to live with.

I look at it this way. It's a HUD and you have over 250 prims available per attach point. Why worry? (^_^)

neatness and readability.
also i couldn't make it multi-page without the buttons overlapping and making a huge mess of prims.
when i can be bothered i'll post screenshots.

@ EF Klaar
yeah they are in nice neat rows & columns and one i've done the first page i can just copy & paste into the rest (another 3) and just edit the button functions & comment out un needed ones.
