Vehicle changed event handler isolating

Hello =^.^= I am scripting my latest sailing ship project for physical movement. And anyway I am having a lot of greif with the changed event handler. I encountered teh same problems back when I was making airplanes and never reallly figured it out. Anyway, the issue I have is that it works just fine for the captiian sitting/unsitting. BUT whenever 1 of the 7 passangers sit on it, peices of that event are get activated. The startup lines may be ran, sometimes parts of the shutting down lines are ran (but not all)

I want to get a way to reorganize this so it TOTALLY ignores any agent sitting/standing up from any of the sittargets in the various child prims in this craft. Here is the relevant section of code cleaned up a bit

 changed(integer change)
    {
        if (change & CHANGED_LINK)
        {
            key agent = llAvatarOnSitTarget();
            
            if(agent != llGetOwner() && agent != NULL_KEY)
            {
               
                llUnSit(agent);
                llPushObject(agent, <0,0,10>, ZERO_VECTOR, FALSE);
            }
            else if(agent == llGetOwner())
            {
                
                gLinearMotor = <0, 0, 0>;
                 llSetVehicleVectorParam(VEHICLE_LINEAR_MOTOR_DIRECTION, gLinearMotor);


                 llSetVehicleFloatParam(VEHICLE_LINEAR_FRICTION_TIMESCALE, 1000.0);
                 llSetVehicleFloatParam(VEHICLE_ANGULAR_FRICTION_TIMESCALE, 1000.0);
                llRequestPermissions(agent, PERMISSION_TRIGGER_ANIMATION | PERMISSION_TAKE_CONTROLS);
                 llSetStatus(STATUS_PHYSICS, TRUE);
             
                llSay(0, "start ran");

             } 
             else if(agent == NULL_KEY)
             {

                gLinearMotor = <0, 0, 0>;
                 llSetVehicleVectorParam(VEHICLE_LINEAR_MOTOR_DIRECTION, gLinearMotor);
                 llSetVehicleVectorParam(VEHICLE_ANGULAR_MOTOR_DIRECTION, gLinearMotor);


                llSetStatus(STATUS_PHYSICS, FALSE);
                 llSetVehicleFloatParam(VEHICLE_LINEAR_FRICTION_TIMESCALE, 1.0);
                 llSetVehicleFloatParam(VEHICLE_ANGULAR_FRICTION_TIMESCALE, 1.0);
                anchor();
                llSay(0, "shutdown ran");

            }
            
        }
        

    }

Thanks for any help! ^_^

I think your script needs to have a llsittarget command somewhere before you can detect the av in the changed listener. Strange, but it worked for me.


See the QA after the first lsl example here:
http://rpgstats.com/wiki/index.php?title=LlAvatarOnSitTarget

There is a sittarget in state_entry and in the child prims for the other sitting positions too. But detecting them is exactly the bug im trying to fix (meaning I dont want to detect them). I'll look into avataronsittarget though!

n/m There is a AvataronSitTarget in there already.
