view text in mouselook

it is a kind of complex idea im working on, when you are in mouselook within a plane you will be able to see the text on the hud but when not in mouselook you wont be able to see it, i had it nearly working a few times but when i go into mouselook it dosent show up atall not sure if this way is the currect way of doing it

integer display = TRUE;

vector pos;
string altitude;
string altitude_sea;
string text;
vector Euler;
integer heading;
integer afterburner;
vector velocity;
string speed;
string throttle;
vector fwd;
rotation rot;

default
{
    state_entry()
    {
        llSetText(" ", <1.0, 1.0, 1.0>, 0.0);
        afterburner = FALSE;
    }
    
    link_message(integer sender, integer num, string str, key id)
    {
        if (str == "start") {
            state active;
        } else if (str == "throttle") {
            throttle = (string)num;
        } else if (str == "display off") {
            display = FALSE;
        } else if (str == "display on") {
            display = TRUE;
        }
    }
}

state active
{
    state_entry()
    {
        if (display) {
            llSetTimerEvent(0.5);
        }
    }
    
    state_exit()
    {
        llSetTimerEvent(0.0);
    }
    
    on_rez(integer sparam)
    {
        state default;
    }

    timer()
    {
        if (display) {
            pos = llGetPos() + (llGetVel() / 2.0);
            pos = llGetPos();
    
            if (afterburner) {
                text = "Throttle: AFTERBURNER";
            } else {
                text = "Throttle: " + throttle + "%";
            }
            
            velocity = llGetVel();
            speed = (string)llVecMag(velocity);
            speed = llGetSubString(speed, 0, llSubStringIndex(speed, ".") + 3);
            text += "  -  Speed: " + speed + " m/s";
            
            rot = llGetRot();
            fwd = llRot2Up(rot * llRotBetween(llRot2Fwd(rot), <0.0, 0.0, 1.0>)) * -1.0;
            heading = llFloor((llAtan2(fwd.x, fwd.y) * RAD_TO_DEG) + 0.5);
            if (heading < 0) {
                heading += 360;
           }
            text += "  -  Heading: " + (string)heading + " degrees";
            
            text += "\n----------";
            
            altitude = (string)pos.z;
            altitude = llGetSubString(altitude, 0, llSubStringIndex(altitude, ".") + 3);
            altitude_sea = (string)(pos.z - llWater(ZERO_VECTOR));
            altitude_sea = llGetSubString(altitude_sea, 0, llSubStringIndex(altitude_sea, ".") + 3);
            text += "\nAltitude (abs): " + altitude + " meters";
            text += "\nAltitude (sea): " + altitude_sea + " meters";
            
            text += "\nCoordinates: " + (string)llFloor(pos.x) + ", " + (string)llFloor(pos.y) + " (" + llGetRegionName() + ")";
        if(llGetAgentInfo(llGetOwner())& AGENT_MOUSELOOK) // added
        {
            llSetText(text + "\n ", <0.25, 0.25, 1.0>, 1.0); //added
        }
} else {
            llSetTimerEvent(0.0);
            llSetText(" ", <0.25, 0.25, 1.0>, 0.0); //added
        }
    }
}

    link_message(integer sender, integer num, string str, key id)
    {
        if (str == "stop" || str == "crash") {
            state default;
        } else if (str == "throttle") {
            throttle = (string)num;
        } else if (str == "afterburner_hud") {
            afterburner = TRUE;
        } else if (str == "afterburner_hud_off") {
            afterburner = FALSE;
        } else if (str == "display off") {
            display = FALSE;
        } else if (str == "display on") {
            display = TRUE;
            llSetTimerEvent(0.25);
        }
    }
}

i was also trying to wire the mouselook with display integers and had no luck

i would remove your added part and make a 2nd script with the llGetAgentInfo
and send llMessageLinked "display off" "display on" to turn on and off
thats what the script was designed for and already has the link_message event
-LW

this was aorrinaly a freebie script that i heavyly modded not sure if it will interact with the other stuff i added, but ill give it a shot

i made a second script for it and it refuses to work right every time i go into mouse look it shows up but it only saposed to work when im seated inside the plane and have mouselook

integer sit;

default
{
    state_entry()
    {
        llSetTimerEvent(.2);
    }
    link_message(integer sender, integer num, string str, key id)
    {
        if(str="seated")
        {
            sit=TRUE;
        }
        else if(str="unseated")
        {
            sit=FALSE;
        }
    }
    timer()
    {
        if((llGetAgentInfo(llGetOwner())& AGENT_MOUSELOOK) && (sit=TRUE)) 
        {
            llMessageLinked(LINK_SET, 0, "start", "");
        }
        else
        {
            llMessageLinked(LINK_SET, 0, "stop", "");
        }
    }
}
