Show/Hide Script help

I don`t know much about scripting

I have 1 linked object that is made up of about 15 prims. I would like the user to be able to hide only one prim of the entire object. I think this script is capable of that? I`m guessing it has something to do with the line that says "llSetLinkAlpha(LINK_SET , 0.0, ALL_SIDES);" Currently the script hides the entire object. I have no idea what command to enter to get it to change just one prim to transparent/phantom... Could somebody lend a hand please or is this more complex then just a small script mod?

Here is the script:




default
{
on_rez(integer total)
{
llResetScript();
}


touch_start(integer total_number)
{

llOwnerSay("Removing Sheet...";
llSetLinkAlpha(LINK_SET , 0.0, ALL_SIDES);
state otherway;

}
}

state otherway
{
touch_start(integer total_number)
{
llOwnerSay("Showing....";
llSetLinkAlpha(LINK_SET , 1.0, ALL_SIDES);
state default;

}
}

You just need to change the LINK_SET to the link number for the prim to hide - finding that number can be a bit more of a challenge.

You may find it easier to use a slave script in the prim which sets the alpha and use llMessageLinked to communicate with it.

to find what prim number you need to hide try this easy way.

1 .- Unlink the object
2.- select all prims.
3.- desselect the prim what you need to hide and the root prim with the script inside.
4.- select the prim to hide and last one the root prim.
5.- Link it all.

Ready you have the prim number to hide in your link set .

If the root prim is the last selected that is the link number 1 the the second is your prim to hide.

llSetLinkAlpha(2 , 1.0, ALL_SIDES); // "2" prim to hide .

It sounds complicated but its simple

Thank you both a ton. worked like a charm. Perfect

Is there any way to also make the hidden piece phantom or is 1 phantom prim in the midst of a non-phantom primmed linked object impossible?

I think if you make one prim phantom all the link set would be phantom ...(correct me if im wrong)
from the wiki:

http://wiki.secondlife.com/wiki/LlSetLinkPrimitiveParams

default
{
    state_entry()
    {
        llSetLinkPrimitiveParams(2,[PRIM_COLOR,ALL_SIDES,<1.0, 1.0,1.0>,1.0]); // visible
         llSetLinkPrimitiveParams(2,[PRIM_PHANTOM,FALSE]); //no phantom 
    }

    touch_start(integer total_number)
    {
        llSetLinkPrimitiveParams(2,[PRIM_COLOR,ALL_SIDES,<1.0, 1.0,1.0>,0.0]); //invisible
 
 llSetLinkPrimitiveParams(2,[PRIM_PHANTOM,TRUE]); //phantom
    }
}

Im not inworld so i cant test it , try it and let us know

If it's the right kind of shape you could make it flexi if you want it to be phantom and linked.

Or you can use a script to manipulate it in other ways too -- shrinking it, perhaps, or cutting a big hole in the middle, using a similar function to llSetLinkAlpha, llSetLinkPrimitiveParams http://www.lslwiki.net/lslwiki/wakka.php?wakka=llSetLinkPrimitiveParams, which might also, depending on the size and shape of the prim, be a good way to achieve an effect similar to making it invisible and quasi-phantom by making it flexy.
