[Trouble making prim detect correct position]

Hey guys,

 

I figured out that if I re-created my prims and start from scratch the positions work perfectly. Problem solved! Thanks anyway.

[Trouble making prim detect correct position]

For some reason my prim detected the end position fine but then later on it doesn't work anymore. Here is my code:

 

integer on = TRUE;
vector pos;
vector startpos = <81.287,87.940,30.251>;
vector endpos = <81.787,84.690,30.451>;
key ToucherID;
integer channel_dialog;
integer listen_id;
list choice = ["1V", "3V", "5V"];
string msg = "Please choose a voltage value for battery:";

default
{
    state_entry()
    {
        llSetText("Touch to move voltage source",<0,1,0>,1);
        llListen(-20, "", "", "");
        channel_dialog = ( -1 *
(integer)("0x"+llGetSubString((string)llGetKey(),-5,-1)) );
    }

    listen(integer channel, string name, key id, string choice)
    {
        if(channel == -20)
        {
            llSetText("Reset!",<0,1,0>,1);
            llSetPos(startpos);
            llResetScript();
        }
        else if (choice == "1V")
        {
            llShout(30, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else if (choice == "3V")
        {
            llShout(31, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else if (choice == "5V")
        {
            llShout(32, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else
        {
            llShout(33, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
    }
   
    touch_start(integer x)
    {
        pos = llGetLocalPos();
       
        if (on == TRUE)
        {
           listen_id = llListen( channel_dialog, "", ToucherID, "");
           llSetPos(llGetLocalPos() + <0,0,0.2>);
           llRequestPermissions(llDetectedKey(0), PERMISSION_TAKE_CONTROLS);
           on = FALSE;
        }   
        else if(pos == endpos)
        {
            llSetText("Correct placement!",<0,1,0>,1);
            llSleep(3.0);
            llReleaseControls();
            llSetText(msg, <1,1,1>,1);
            llSleep(3.0);
            ToucherID = llDetectedKey(0);
        llDialog(ToucherID, msg, choice, channel_dialog);
        listen_id = llListen( channel_dialog, "", ToucherID, "");
        llSetTimerEvent(60); //HERE WE SET A TIME LIMIT
        }
        else if (on == FALSE)
        {
            llSetText("Wrong spot...",<0,1,0>,1);
            llSetPos(pos);
            llRequestPermissions(llDetectedKey(0), PERMISSION_TAKE_CONTROLS);
            llReleaseControls();
            on = FALSE;
        }
    }
   
    run_time_permissions(integer perm)
    {
        integer controls = CONTROL_FWD | CONTROL_BACK |
             CONTROL_ROT_LEFT | CONTROL_ROT_RIGHT;
        if(perm & PERMISSION_TAKE_CONTROLS)
        {
            llTakeControls(controls, TRUE, FALSE);
        }
    }
   
    control(key id, integer level, integer edge)
    {
        integer button = level;
        if(button & CONTROL_FWD)
        {
            llSetPos(llGetLocalPos()+<0,-0.25,0>);
        }
        if(button & CONTROL_BACK)
        {
            llSetPos(llGetLocalPos()+<0,0.25,0>);
        }
        if(button & CONTROL_ROT_LEFT)
        {
            llSetPos(llGetLocalPos()+<0.25,0,0>);
        }
        if(button & CONTROL_ROT_RIGHT)
        {
            llSetPos(llGetLocalPos()+<-0.25,0,0>);
        }
    }
   
    timer()

[how to make avatar carry a prim and place it on top of another prim?]

I would like to know how to make avatar move a prim by carrying it and place that prim on top of another prim. I would like to make a circuit board and have these prims (components) placed on the circuit board (another prim). Also how would I make the circuit board prim detect the location of the prim placed on top so that the avatar can get a message saying the prim (component - ie. resistor) is placed in the wrong part of the board? Thanks
