Land Follow Script

I'm trying to make an object follow me using llmovetotarget but i want it to stay along the ground or the platform i'm on, i've tried using:

llDetectedPos(0) - (llGetAgentSize(llDetectedKey(0)) / 2)

For the height of the object when it moves to it still seems to hover a little bit off the floor, any ideas on how this could be done?

If you look closely you might notice you hover a little bit off the floor. It's messy but you could try:

llDetectedPos(0) - (llGetAgentSize(llDetectedKey(0)) / 2) - offset

Where offset is a vector like <0,0,-0.1> or whatever you need.

Personally I would assign the (llGetAgentSize(llDetectedKey(0)) / 2) - offset part to a variable when the object initializes so that you don't have to calculate that over and over again.

Something like:

// This is untested sorta fake code. Don't try to compile.

// A slight drop to account for that hover you mentioned.
vector adjustment = <0,0,-0.1>;
vector offset;

default {
     state_entry() {
          vector height = llGetAgentSize(llDetectedKey(0));
          // You really only need the avatar height, not width and depth.
          offset.z = (height.z / 2) - adjustment;
     }

     // The movement part.
     llDetectedPos(0) - offset;
}

Hey, look over there.

I would also recomment what Jesrad describes here, using the vehicle system to make the pet move.
