Draw/Sheath script for shield

I have done shield which i want to draw/sheath visible (other one is worn in L forea-arm) and when drawn becomes visible. Same time shield worn in back will become invisible. With sheath command everything works opposite way.

I know this has to be done with llSetAlpha command. I have tried to put this script to shield

default
{
link_message(integer sender, integer channel, string msg, key id)
{
if (msg == "sheath" llSetAlpha(1, ALL_SIDES);
else if (msg == "draw" llSetAlpha(0, ALL_SIDES);
}
}

but nothing happens when i type draw or sheath command. Any help?

First, a link_message() event is triggered only by another script sending an llMessageLinked() message. You need a listen() event and an llListen filter.

Second, that will only work if the sheild happens to be one prim. Instead of llSetAlpha you can use llSetLinkAlpha to set a whole link set's alpha.

See attached script =^.^=

Thank you very much for helping. I got idea how to do it and got shield in back and hand working (making them visible depending if shield is drawn or "sheathed to back". Hmm maybe i change draw and sheath command to wear and use shield commands) Anyway i got another problem related to animation or llStopAnimation command.

I use following script to make shield pose animation (holds left arm lift up and so that it keeps shield front of body)

string anim ="drink";
string anim2 ="Shield pose";

default
{
    attach(key victim)
    {
    if(victim == NULL_KEY)
    {
          llStopAnimation(anim2);
          llStopAnimation(anim2);
          llSetTimerEvent(0);
          
        }
        else
        {
         llRequestPermissions(victim,PERMISSION_TRIGGER_ANIMATION);
    }
}

   run_time_permissions(integer permissions)
    {
        if (PERMISSION_TRIGGER_ANIMATION & permissions)
        {
        llStartAnimation(anim2);
         llStartAnimation(anim2);
        
        llSetTimerEvent(15);
        }
    }

   timer()
   {
    llStartAnimation(anim2);
    llStartAnimation(anim2);
    }

}

Naturally i have shield all time attached to hand so if i make it invisible animation still continues. I havent yet figured out yet how to use llStopAnimation so that when i command in channel 1 sheath shield animation script is stopped.

Your best bet is to combine the functions in one script. See attached.

Thank you Jillian!

I had to change last part of the script to look like this so that i would get this working correctly
..................

if (msg == "sheath"
{
llSetTimerEvent(0.0); // Stop the timer so the anim does not get re-run.
llSetLinkAlpha(LINK_SET,drawn, ALL_SIDES); // Make the item invisible
if(llGetPermissions() & PERMISSION_TRIGGER_ANIMATION) llStopAnimation(anim); // stop the animation
}
else if (msg == "draw"
{
llSetTimerEvent(5.0); // Re-start the timer
llSetLinkAlpha(LINK_SET, sheathed, ALL_SIDES); // Make item visible.
if(llGetPermissions() & PERMISSION_TRIGGER_ANIMATION) llStartAnimation(anim); // start the animation
}
....................

I changed to llSetLinkAlpha drawn & sheathed places. Now commends show them wrongly but it now works correctly. Otherwise when i type /1draw shield becomes visible in hand but animation stops and when i type /1sheath shield becomes invisible but animation starts.

Thanks again for a help! I will send you as a thanks that shield!
