visible/invisible when using poseball

I tried to find it but didn't, it's proparbly asked a trillion times,
i don't even know how it's called but i give it a trie:

i've made an structure with a poseball, and if i click the poseball i want to change 2 prims in the structure. So i want 1 prim be invisible an the other visible, when i use the poseball it must be the other way round (visible/invisible)... is this possible???

Thanks

yes, do this

integer vis;

default
{
state_entry()
{
vis = TRUE;
touch_start(integer touch)
{
if(vis == TRUE)
{
llSetAlpha(0,ALL_SIDES);
vis = FALSE;
}
else if(vis == FALSE)
{
llSetAlpha(1,ALL_SIDES);
vis = TRUE;
}
}
}

that should do it, im not in world atm to test it, atmost there is just a few minior errors
and for the other prim you can reverse the 1 and 0 in llSetAlpha and use a link message, on command have the other prim turn inv or visable

Thanks so far ... there is an error and my scripting skills are almost zerro...

A curly bracket was missing.

 integer vis;
 
 default
 {
 state_entry()
 {
 vis = TRUE;
 }
 touch_start(integer touch)
 {
 if(vis == TRUE)
 {
 llSetAlpha(0,ALL_SIDES);
 vis = FALSE;
 }
 else if(vis == FALSE)
 {
 llSetAlpha(1,ALL_SIDES);
 vis = TRUE;
 }
 }
 }

Thanks verry much... as soon as we can login again i gonna give it a try... Big THANKS!

as i said before, i wosent able to get in sl for a wile + downtime atm didnt help, atleast it was only a little bit of a error, one of the key tricks to learning lsl is looking at freebie scripts studying them and looking up there funutions on wiki

wiki.secondlife.com

that is one of the best ways i found out on how to learn lsl, take it slow and learn what it takes for what your building ect, and yes this is a random post,

/me waits for grid to get its switch turned on

hmmm it seems i can't get it working the way i want it...

I try to explain it again:

I've made a gallow pole with a hanging pose
and made two knots, the 1st hanging down (for when nobody's dangle)
and the 2nd for arround the neck, but want them to show one at a time...

Now i want the 1st knot showing when nobody's dangle and the 2nd is invisible,
when sombody is using the poseball, and is gonna dangle, i want the 1st knot dissappear and the 2nd knot (arround the neck) appear... When he/she jumps off 1st showing 2nd dissappear again...

Sorry if it's confussing, my english is not that well...
But thanks for even reading my post

i get what you mean, forget what it is called but something about changed links, when avatar go on pose ball it will send a linked message to the 1st not to turn alpha (inviable) and 2nd not to turn visable, and when you get off it sends a messge for bot 1 to turn vis and not 2 invisable

EDIT:

 changed(integer change)
    {
        if (change & CHANGED_LINK)
        {
            key agent = llAvatarOnSitTarget();
            if (agent)
            {
                   // link message to tell knots what to do
                   // avatar on poseball
            }
            else
            {
                // link message to tell knots what to do
               // avatar gets off
            }
        }
        
    }

try using that
