Fix Camera Lock to Object

[KiondraeLoc]

This is the script I have in my hud:

string TargetName = "n";
default {
    
    state_entry() {
        // run this code when entering the default state
        // displays red "OFF" as floating text above the prim
        llRegionSay(3, "off");
        llSetText("OFF", <1,0,0>, 1.0);
        llRequestPermissions(llGetOwner(), PERMISSION_CONTROL_CAMERA);
 llClearCameraParams();
  llSetTimerEvent(0.0);
    }
    touch_start(integer num_detected) {
        // when touched, switch to state named 'on'
        state on;
        llRegionSayTo("n", 3, "on");
    }
     }    
        
      
    

 
state on {
    state_entry() {
       
        llRegionSay( 3, "on");
        // run this code when entering state 'on'
        // displays green "ON" as floating text above the prim
        llSetText("ON", <0,1,0>, 1.0);
            llRequestPermissions(llGetOwner(), PERMISSION_CONTROL_CAMERA);
 llSetTimerEvent(0.022);
  llListen(4, "","", "");
  
 
 }
  

    touch_start(integer num_detected) {
        // when touched, switch to the default state
        state default;
    
    }
    listen(integer channel, string name, key id, string message)
    {
        if(llGetPos())
        {
           list data = llGetObjectDetails(TargetName, [OBJECT_POS, OBJECT_ROT]);
        vector pos = llList2Vector(data, 0);
        rotation rot = llList2Rot(data, 1);

        llSetCameraParams([
            CAMERA_ACTIVE, TRUE,
            CAMERA_FOCUS_LOCKED, TRUE,
            CAMERA_POSITION_LOCKED, TRUE,

            CAMERA_FOCUS, pos, 
            CAMERA_POSITION, pos + (<0, -2, 1> * rot)  
        ]);
        }
    }
    

}

This is the script I have in my RC Flying Drone: 

string TargetName = "n";
default{
    on_rez(integer r){
        llResetScript();
    }
     state_entry()
    {
        llListen(3, "","", ""); 
    }
    listen(integer channel, string name, key id, string message)
    {
         if (llGetOwner() != llGetOwnerKey(id))
        {return;}
        
        if(message == "on")
        {
             
          llSetTimerEvent(0.05);
        }
          
        if (message == "off")  
        {
            llSetTimerEvent(0.0);   
        }
        
        }
 timer()
    {
      
  llSetObjectName(TargetName);     
        llRegionSay(4,(string)llGetPos());
    }
}

How can I get the camera to track the object and not the bottom left corner of the sim at <0,0,0>? I don't want to use the object uuid, I want to use the name of the object to track on a channel so I don't have to keep changing the uuid of my object every time I rez it.

I'm not quite sure what you are asking for, but when I design something like this, I make the HUD be the rezzer that generates the drone.  That way, I automatically know the UUID of the drone as it is created, from the result of an object_rez event.

Am somewhat confused at the OPs request myself seeing as that is what the object_rezz event is for.

What does this do?

listen(integer channel, string name, key id, string message)
    {
        if(llGetPos())

Literally?  It says, "If my present location is not <0,0,0>, go ahead and do stuff ..."

But what is the point? Maybe i am half asleep because i just do not get it.

Oh, I have no idea. Personally, I would not want a HUD that only works if I happen to be standing at <0,0,0>.

The odds of that are higher than you being the first woman on the moon.

Which is pretty much anywhere.

I think the OP misunderstands llGetPos() as being the position of the drone, relayed to the HUD via llRegionSay in the timer event. The HUD's listen event makes no reference to the message it receives, and the only thing the drone says is its position. If the HUD were actually looking at the message, I don't think the OP would be asking this particular question.

Yup, and I was hoping that the OP would figure that out for herself.  😉

Would make more sense doing this.

listen(integer channel, string name, key id, string message)
    {
        if(name == "whatever_it_called")
        {
            llOwnerSay( (string) id );//use this data for whatever purpose. Make it a global variable if you want to.

        }
    }
