how to set terminal points of child llSetPos()?

Hi,

Anyone can help with this?

Imagine a 3-prim object (say a lipstick container Prim #1 and a a 2-prim lipstick, Prim #2 and Prim #3), all linked. I'd like to be able to get the lipstick (Prim #2 and #3) to move out of the container upon touching Prim #2, and to recede back to the container upon touching Prim #3.

How do I set the extreme limits of Prim #2 and #3 so they don't move upwards or downwards forever (or up to 10m) when touched?

Thanks a bunch.

Well, assuming things about your build I can't know...

vector position = <0,0,0>; // Uh, whatever fully retracted might be.
                                       // and I'm assuming extended is along the Z axis.
float myz = 0;

link_message( integer src, integer num, string msg, key id)
{
     if ( msg == "extend" )
     {
          myz = myz + 0.01;
          if ( myz > 1.0 ) myz = 1.0;
          position.z = myz;
          llSetPos(position);
     }
     else if ( msg == "retract" )
     {
          myz = myz - 0.01;
          if ( myz < 0.0 ) myz = 0.0;
          position.z = myz;
          llSetPos(position);
     }
}

And the scripts in the other two prims would just send the extend and retract messages with llMessageLinked.

Someone will be along shortly to teach me a better way

okay I modified the above code a little in my experiment (forgive my poor newbie scripting skills). Unfortunately it hit a syntax error and I can't figure out what's the problem:

default
{
  
    state_entry()
    {
        vector position = <0,0,0>;  
        float myx = 0.5;  
    }

    touch_start(integer total_number)
    {
          myx = myx - 0.01;                            // <===SYNTAX ERROR HERE
          if ( myx < 0.0 ) myx = 0.0; 
          position.x = myx; 
          llSetPos(position);


        vector location = llGetLocalPos();
        llSay(0,(string)location);
    }
}

The error message was: Name not defined within scope, and the cursor was pointing at the first "myx". Any ideas?

Thanks,

Move the "float myx = 0.5" out to above the default line. Where you have it now, that variable exists only within the state_entry event, and disappears essentially as soon as it's created. When you move it above the default (and outside of the state) it becomes a global variable available at all times.

Thanks very much! Will try that.
