llRotLookAt headaches

Hi all,

Just to pass time I made a bird, got it to move randomly inside a bounding area, etc. It's all nifty.

Ok but the bird flies butt first sometimes, side first other times, it's very annoying. I cant seem to get a consistent side of the prim with the script in it to face the destination when using llRotLookAt().

Any suggestions? :confused:

I am not in world atm, but maybe something along these lines?

CODE
vector origin = llGetPos();
origin.x = destination.x + randomx;
origin.y = destination.y + randomy;
origin.z = destination.z + randomz;
vector destination = ZERO_VECTOR - origin;
llRotLookAt(llRotBetween(<-1, 0, 0>,(destination - origin)) , 0.5, 0.5);



randomx, randomy and randomz would be your randomly generated values for movement. Like I said, not in world, so I can't confidently stand behind this. I'll try and get in world in a bit and check it out for ya though.

I use a short timer that uses llLookAt to have my A-life fish look where they're going. I don't have acess to the script ATM, but it uses llGetVel (vector along which the prim is traveling) with llGetPos() to get the point that the fish is traveling to, and applies the value to llLookAt() to have my fish look in that direction.

The function is working perfectly fine. It's just not working the way you wanted it to work.

^.^

I could use this with rockets...

And then combine that with the key-passing functions in another post (/54/18/77274/1.html)...

And set up a nice rocket launcher with realistic moving rockets!

Neat.

Senuka,

Are the fish physical? I thought llLookAt was only for non physical objects. *checks wiki*

Nope, works for both! yay!

I'll give it a shot tomorrow, would love the code from your script tho to make it easier :)

Thanks :)
