how to follow an avatar who is located above 1000 meters or more in region?

[elyzeryd]

I'm trying to make a HUD to catch an avatar who is flying above 1000 meters or more in region.

Well, there are several script to follow an avatar in SL; it works only if the avatar is relatively close, under 98 meters). There are some items in marketplace to follow an avatar no matter the distance they are...

Could you please give me some ideas what function(s) or method do i need to use to create a script to get it?

Thank you.. hope you can help me.

llName2Key converts avatar names into UUIDs.

llGetObjectDetails is able to get a lot of useful data about an object/avatar in the region, such as position, rotation, and velocity.

Also llGetAgentList gives you a list of all avatars in the region in UUID form, regardless of distance. This is not necessary if you know the target, though.

That should be enough for you to figure the rest out.

this is a combat HUD so it is easy to get a list of avatars in region. no matter the distance... they are usually above 10,000 or 50,000 meters... the goal is move your avatar untill you reach that position...  llMoveToTarget doesn't work...

If your ultimate destination is further than the llMoveToTarget() limit, you just have to run it in a loop or a timer event with smaller steps that move you toward your goal. 

llVectorNorm() multiplied by a scalar and added to llGetPos() should break it into a small enough step.

You might also look at llSetForce. Something like 1000.0 in the z direction will get you somewhere around maximum SL velocity. Polling your target's position will let you track towards it, with a little help from some trigonometric or rotation calculations.
