Radar that detects agents up to 300m?

Hi I have this text based HUD that detects users up to 96 meters and gives me their location. On WIKI there is a bug/feature that allows users to detect agents locations up to 300m away.

Does anyone happen to know what this bug/feature is?


Thanks! :)

Yup - the bug is that when you say you want to scan for avies that way, sometimes, in spite of the 96m "limit" it will report back on people who are over 300m away

It get's better - I've had reports back on agents that were in the NEXT SIM - around 250m away total, and in a sim to the side of my travel, so not even a sim that I had been in or was headed into.

And THAT is just weird.

If it hadn't kept happening for about 15 minutes, I woudln't have believed it.

And I know where they were because I was working on a mapping radar script, and was checking my results with the minimap at the same time.

Sadly, there doesn't seem to be any way to 'force' the behaviour - often you just get the 96m range, even when you KNOW that there are people at 97m, and 250m, and 400m etc.

It's not really a feature, someones on private islands or when the sim is feeling generous it'll give you sensor input up to 300m or more away.

I think the greater than 96m entries in the return list are errors. I did some testing when I was making the HUD Scan and none of those people were actually anywhere near me in my current sim or any sim around me. HUD Scan discards returns greater than 96m for this reason.

What bothers me is the bug where worn 'avatar radars' don't get returns from across sim lines, but unworn they work over sim lines. Further I know this was added? to the game Right after HUD Scan came out as it worked across sim lines in the two weeks of beta testing and for the first few weeks of release. Most annoying.

I think text/chat avatar radars are annoying anyway, which is why I made HUD Scan as soon as the tech making it possible was added to SL. Much less annoying.

You could be correct about the >96m being errors, but my personal hud is based on a full map of the sim, not just a 96m range, and it does indeed sometime put people on the map in places where they are 250m away, and they also appear on the minimap there, too, so it certainly isn't always just a random blip.

Actually, I've gone and checked quite a few times with my radar when it shows people 300+m away, and it's never been wrong, even across sim borders. It doesn't always find everyone that's in a cluster of people, but anyone it says is somewhere is there.

I've hit about 700m away using Argent's otter monitor. That was almost directly up, and only with certain people(the folks next to my plot have a high, high skybox, and when I am on the ground that can be detected as they move around.) I don't know what it is about the spot, but it's constant within my parcel.

You can't rely on any of this stuff, though. I usually screen out anything with a detected distance greater than the scan range, because I'm not confident in the data and I'm not confident that decisions I make based on it will make sense. If I scan somebody I want it to indicate that they are definitely in a certain position, and that my next scan will report their position (if inside scan range) as well.

My sensor at 715m altitude regularly reports avatars on the ground. Doesnt seem to work as far in the horisontal plane though.

I use a Security HUD and it consistantly returns 300m's or less.

I realize a regular sensor sometimes can return more than 96m but as far as I can tell it isnt consistant.

It is accurate (security HUD) because I've tested it and use it for protection.

Some folks say use relay sensors via other objects. my detection HUD doesn't use any relays according to all the beacons I have enabled.

There has to be a consistant way of detecting Avies up to 300m.

Thanks

I don't think there's a consistent way - there's not even a consistent way to detect them in the next sim after all.

One consistent thing I have noticed, that I should bug report I guess, if you're in an edge sim (I live in one) you can regularly "wrap around" and detect people on the other edge of the sim. Standing in a corner makes it even freakier, you can't quite scan the whole sim, but you can get arcs about 96m in from each corner.

Why?


It is a glitch in the system that it allows this at all, ever.

And if you want to break it even more, go somewhere where there are more than 16 other avies in range, you'll only get the first 16 of them.

If you want reliable, consistent, guaranteed detection of everyone within 300m of you, then good luck. you will need a huge grid of remotes, to get around the 16 av limit. Since you can cluster 16 avs within about an 8m x 8m square if you try (assuming they are on the flat - much smaller if you stack them, or use sit targets to overlap them, etc.) then you'll need something like one sensor every 8m, which is a1024 sensors to cover a whole sim (which could be as little as 128m range if you are stood in the center of it, so still less than your 300m requirement.


in reality, for reasonable use - a 96m limit is plenty. if you want more, you need remotes. 5 remotes can cover a full sim at ground level. add more if you want air cover. relay all the data back to the controller via llShout, and make sure that the remotes die if you leave the sim. It will still fail if you have a cluster of >16 avies in one location.


And, finally, remember that the >96m range is officially a bug, which means that one day LL may well fix it so that it stops doing that forever.

When I get in game I will let you know the name of multiple Detection objects that consistantly return 300m or less distances.

This is why I said there is a consistant way to do thjs, because I own proof it can be consistant. The one I use most often is the Personal Security HUD.

This does not work from one sim to the next consistantly, but I think we've all come to expect that.

You could consistently cover a sim by rezzing detectors and sending them out to about (67.5, 67.5), (188.5, 67.5), (67.5, 188.5) and (188.5, 188.5) - you'd have to worry about heights and things too I guess.

So smart coding could let you interpret all the data.

Doing it routinely will make you unpopular - why do you need this amount of sensor information in someone else's sim? Have you thought about what it's likely to do to the script load?

Ditto. :D Not a plug, just an example.

LOL you didnt even read my post. You said 2 things I said I didn't want to do.

I am talking about one single object (not rezzing other objects with a relay because that's dumb)

I do NOT expect it to detect the other sim because that isn't realistic.

I DO want a sensor script that detects avatars up to 300m consistantly.

There are objects out there that currently do this. They do it consistanly.

My current Agent sensor works great but it works up to 96m.

I'm curious how my HUD that I purchased scans to 300m without relays. That is it.

The answer is they don't. They might rez another object to do it, but there's no consistent way to have a single object scan like that. llSensor is limited to 96m although it does wrap oddly sometimes.

I've noticed that you usually get these reports from other sims when there is no-one or only 1 person other than you in your sim. And it only updates every 5 seconds so if you are scannng more often, then you may or may not get them reported on subsequent scans.
