more movement questions

I'm wanting to make a beacon and an object that can move to the object using llApplyImpulse. I got the beacon that is using llRegionSay (I want the object to move all over the sim). I'm having problems giving the vector coordinates to the object to move though. It's listening on the channel it knows what to do once it gets the vector I just dont know how to give it the coords. Can you help me?

If your passing the coordinates through the listen, I would cast the coordinate vector to a string and then before you use it cast it back to a vector.

There is another way. Let the beacon just say "Beacon" (for example).

And in the moving object:

listen(integer channel, string name, key id, string msg)
{
if (msg == "Beacon"
{
llListenRemove(Handle);
llRegionSay(Channel, "STFU"; // Eventually...
// The useful line:
BeaconPos = llList2Vector(llGetObjectDetails(id, [OBJECT_POS]), 0);
}
}

To move to a target with llApplyImpulse(), I'd use something like:

timer()
{
vector pos = llGetPos();
llApplyImpulse(llVecNorm(TargetPos, pos) * llVecMag(TargetPos - pos), FALSE);
}

But don't trust me on this one... Yesterday I launched a supersonic object that must be orbiting around SL as we speak.

That is a hell of a lot simpler. I'll test it out in a bit and tell you how it goes

Well your applyImpule line is giving me a script error and when I try to fix it the object will start hopping in a straight line when it gets the command

llVecNorm() takes only one argument. With llApplyImpulse() you are adding to the object's MOMENTUM (velocity times mass). I'd suggest something more like:

timer()
{
   vector currentVel = llGetVel();
   vector desiredVel = speed*llVecNorm(targetPos-llGetPos);
   vector dp = llGetMass()*(desiredVel-currentVel);
   llApplyImpulse(dp, FALSE);
}

Gravity may still affect your path unless you've set a force or buoyancy, so unless the speeds and times at which you are operating are such that any acceleration due to gravity is insignificant you'll have to consider ballistic trajectories.

Note though that llMoveToTarget() may do what you want in a simpler and more efficient manner. All you need for that function is a target position and a timeframe for exponential damping to that position. See http://www.lslwiki.net/lslwiki/wakka.php?wakka=llMoveToTarget

No idea what I was thinking of... Here is what would be syntactically correct:

timer()
{
vector offset = TargetPos - llGetPos();
llApplyImpulse(llVecNorm(offset) * llVecMag(offset), FALSE);
}

Any way, follow Heewee advice... I never use llApplyImpulse() for anything but kicking objects away. llMoveToTarget() is the most logical choice to reach a destination.
