so i'm trying to write a script that keeps you from falling down above 80m off the ground... but it isn't working. for some reason I set the llOwnerSay to confirm the distance from the ground and all it returns is 25.7... blah blah blah. no matter how high or low I am. wtf is wrong? :)
From: someone

default
{
on_rez(integer sp)
{
llResetScript();
}
state_entry()
{
llSetTimerEvent(.5);
}
timer()
{
float grounddist = llGround(ZERO_VECTOR);
llOwnerSay((string)grounddist);
if ( grounddist > 80 )
{
llApplyImpulse(llGetMass()*<0,0,10>,FALSE);
}
}
}

llGround returns the z axis of the ground, not your object

Instead of re-inventing the wheel I'd suggest you go and get yourself a thing called "flight feather".

Should be a freebie toy that does exactly what you want.

Or the flight band - this also allows you to fly in no-fly zones, not that I would do such a thing. PM me if you want one and I'll send one over when I'm next online.

I highly recommend the flighfeather. It is now up to version 1.4 and offers a menu control system for setting the options you want. The script that powers it is Cyberflight 1.4 which is open source so can be used in any of your projects. It is also well commented so you get a good understanding of what it's doing.

Try working out your own script, then compare it to those open source scripts once you think it's working how you like. WAY TO ENCOURAGE CREATIVITY, GUYS. :(

To add za little detail to what Osgeld said.

llGround() is the height of the ground itself.

llGetPos is the position of the object containing the script, or the avatar if it is attached (I think).

llVecDist( llGround( <0,0,0> ), llGetPos() ) would be the height above the ground.

Thanks for the recommendations to the flight enhancers, but the whole deal is that I learn to write that sort of script myself =p

Lee, wouldn't llVecDist(llGround(<0,0,0>;) , llGetPos()); not compile since llGround is a FLOAT not a VECTOR, and llVecDist finds the distance between vectors?

Keep on re-inventing the feather Aniam. Fresh perspective is always good.

I use ground like this:

CODE

default
{
	touch_start(integer total_number)
	{
		vector pos = llGetPos();
		float ground = llGround(ZERO_VECTOR);
		if(pos.z > (ground + 50))
		{
		}
	}
}
