Energy

I was just reading the thread /54/0a/235123/1.html on llMoveToTarget(), where someone mentioned a possible "lack of energy" in an object. At first I thought it was a joke, but it has a real link to a real article on the second life wiki ().
What is the use of this? I always thought that one of the advantages of SL physics was that we don't have to worry about energy as in RL physics.
What will be next? Gas stations along the Linden roads to fuel our vehicles?

'Energy'/'Friction'/'Materials' and their relation to SL physics is currently being discussed in this on-going thread /54/0a/235123/1.html

Don't mixed up "energy" as it relates to SL physics, and "fuel/energy" as it relates to RL; same word, different concepts. Altho' I suspect you were just being whimsical....

Yes, that is the thread I was referring to. And yes, my posting is intended to be more-or-less whimsical. But I was hoping to be able to seperate this concept of energy from the correct working of llMoveToTarget(). I so much hope these problems are NOT related. So I did not want to contaminate that thread.

I think we want llMoveToTarget() to do what it is supposed to do: Move an object to a target.

I don't want to live in a world where objects can loose energy, without a way to give them new power! Give me gasoline and I will build you a four-stroke engine, give me streaming water and I will build you a watermill, give me electricity and I will build you a hair-dryer.

Opps. My apologies. This blasted llMoveToTarget problem is sending me bog-eyed, I think

If you are dealing with little/small-mass objects and velocities that aren't huge, you probably don't have to worry much about energy. Small objects get it back very quickly. For example, an attachment that moves the avatar around (all such attachments register with a mass equal to the avatar's) can pretty much do so without restriction and not run out of energy.

If you are dealing with massive objects and want physical movement, the only way I know of to get around energy considerations is to use vehicle functions, which don't sem to be affected by energy or mass (but have pretty limited speeds, unfortunately).
