Start a script only when sitting on the prim

Hi guys,

I have this nice bouncing script from the forums that I am modifying for use in a pogo stick. It works quite well, except for two things:

1. It starts bouncing on_rez, and I would like it it to only start when I get on it

2. It only bouces on land, not on solid objects such as floors of house. Is there an alternative event to the land_collision event?

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

   state_entry()
   {
   llSetStatus(STATUS_PHYSICS,TRUE);
   llSetStatus(STATUS_PHANTOM,TRUE);
   llCollisionSound("c02681b3-52f3-dfa0-416b-3f414fb01aef",1);
   }

   land_collision_start(vector x)
   {
   llSetStatus(STATUS_PHYSICS,FALSE);
   llSetPos(llGetPos() + <0,0,2>);
   llSetStatus(STATUS_PHYSICS,TRUE);
  }
}

any suggestions, as ever, appreciated

Look up info on the "changed(integer change)" event... specifically, the "CHANGED_LINK" portion, which can tell if someone is sitting on the item.

Thanks for that Starfire, it looks like what I need. I have tried to work this out from scratch, step-by-step, using the standard 'get off!' script. As I am going to introduce the land collision event later, I first want the rezzed object to be clearly off the ground. Unfortunately the code i have tried does not work, and in fact putting a llSay(0, "Hi there"; inside the on_rez state results in nothing being said at all. Why is my on_rez state not functioning as I think it should?

default {
    on_rez(integer x) 
    {
        llResetScript();
        llSitTarget(<0, 0, 0.1>, ZERO_ROTATION); // needed for llAvatarOnSitTarget to work
        llSetPos(llGetPos() + <0.0, 0.0, 3.0>); // Ensure rezzed prim is not touching the land
    }
    
    changed(integer change) 
    {
        if (change & CHANGED_LINK)
            { // if something changed AND it was a link change
            key av = llAvatarOnSitTarget();
            if (av) 
                {
                llSay(0, "Get off!"); // say in chat when person is remove from prim
                llUnSit(av); // unsit him
                }
            }
    }
}

TIA

it was a simple mistake, on_rez() means when it is first spawned from a object or item,

you need a llSiTarget in state_entry() after on_rez()

default
{
on_rez() // whne first rezes
{
//stuff
}
state_entry() // everytime scritp restarts
{
//stuff
}

I have a carosel and want rotation to start once avi is seated on a prim, rotation script is in another prim. Is there a way to have the rotation script start once the avi is seated in the other prim?

Thanks

assuming the other script is running, and waiting for an event, send it a message to start/stop when an av is detected, or better just do that IN the rotation script. something like

changed( integer vIntChanged ){
if (llAvatarOnSitTarget()){
//-- do rotation
}
}

if the script isn't running, you'd need a script in the same prim that turns it on, something like the above, but instead of //-- do rotation you do womething like

if (llAvatarOnSitTarget()){
llSetScriptState( "rotationScriptName", TRUE );
}else{
llSetScriptState( "rotationScriptName", FALSE );
}

the first example is better for most uses
