PLEASE NOTE:
I no longer have any intention of posting comments or updating the addon text (excluding major changes) for this website... keeping track of html/bbcode/xcode for three different websites is just too much of a pain and TBH I like this website the least out of Curse/WoWI/WoWUI.

If you've got a comment please email me or comment on another addon site. Thanks!

Now working with both the WotLK beta and patch 3.0, which went live on servers last Tuesday.

Paranoia will have a KoS list feature in a future version... I've already started working on it in 1.11. I've been visiting family in Argentina for the past three weeks so I haven't been able to write a single line of code, but once I get back next week I'll start working on the addon again. I suggest downloading the 1.11 beta from WoWAce.com, there's plenty of new features in it and even though it's not finished it seems to be stable enough. Support for KoS exists in 1.11, there is just no way to browse through the enemy database yet. That will probably come in 1.12.

Yeah I've been meaning to add this for a while, I just keep forgetting to do it. Then the next time I run an instance I remember it again.
Added in 1.11, which will be out soon. It isn't an option, it just automatically disables itself in an instance since there isn't any reason to have it.

This was a mistake while tinkering with the detection code for 1.10, I did not test it after making the change, and I apologize. I've been smacking my head against the desk for letting that issue slip through while 1.10 was downloaded over a thousand times.
The issue is fixed in 1.10b, and I implore you to give Paranoia another shot, as it should be working perfectly now. :)
If you've got any other suggestions for improving the addon, I'd love to hear them! Thanks!

Glad you like it. :)
While there is no button anywhere to clear the list, you can use the debug command /paranoia clear to clear the hostile list, ignore list, and warning timeout. I'll probably just move that command out of the debug list and into the regular slash command list.

Unfortunately, what you've suggested isn't something I can implement. When Paranoia detects an enemy's combat log event, it only knows that someone is there, but not where they are. Even if you target an enemy, the WoW API function that gets a unit's coordinates only works on yourself and those in your party or raid, so it's impossible for Paranoia to know where the player is.
Usually, what I do is target an enemy, send my pet after them and then quickly recall the pet. The pet will begin walking in the enemy's direction so you can have a general idea of where they are. Obviously this doesn't work without a pet, but that's really the only thing you can do.

I'm not sure what else you were expecting Paranoia to do; it detects enemy players, puts them in a list with their class and estimated level, and warns you. You can target them by left-clicking, and announce them by right clicking. It might not be as robust as Personal Sentry, but clearly enough people have downloaded the mod (and enjoyed it) that it is not a "useless memory hog." Thanks for the useless comment.
If you've found that the mod doesn't meet your expectations, perhaps you could add some suggestions or some actual helpful criticism, rather than just a comment saying "This mod blows." I'm all for taking suggestions and criticism about my addon -- in fact I appreciate it -- but comments like the one you just posted are not in any way helpful.

I am not sure what is up with the occasional false positives... I get them too, rarely, where a unit who is friendly to me and is generating lots of blue (friendly) combat log events will out of the blue generate a red (hostile) one. It seems to be a bug with the combat log itself, since it's feeding Paranoia wrong data. Not really anything I can do about it since it's not a bug in Paranoia's code.

As for getting notices in Shattrath, that shouldn't be happening. If the Paranoia window is invisible, it will not (or at least it shouldn't) make a sound or popup. Be sure you're using the latest version (currently 1.09) and make sure Disable in Sanctuaries is checked in config. You can also try /paranoia testwarn while you're in Shattrath and see if Paranoia triggers (as long as the Paranoia list is invisible, it shouldn't.
You also say you get notices while being in "any town", that is the intended behavior, Paranoia can only disable itself in Shattrath, a BG or Arena, or a Free-For-All zone. If you're sitting in Stormwind and a rogue starts fighting guards (or a player zoning in from a BG has debuffs on him) Paranoia is going to detect them.

@Halfmike666:
Well luckily it's Blizzard who gets to decide what is a cheat and what isn't. To quote someone on the WoW forums:
-----
Mods can only do what Blizzard enables via the Lua programming language. All mods are fine. If Blizzard doesn't like the direction that mod authors are going, they just disable that function.
-----
And I'll go ahead and paste what I just posted on the WoW forums this morning:
-----
Paranoia detects nearby hostile players solely by using incoming combat log events (soon It'll use mouseover and targeting, but both of those pretty much guarantee the user already knows the enemy is there). This information is and has always been available to all players and addons, regardless of what tracking spells are up or not up.
Paranoia isn't even the only addon that does this... far from it. I can think of several addons that look through the combat log for events caused enemy players, including NECB, a popular, widely used enemy castbar mod that could be configured to show castbars for units not currently targeted. And as mentioned above, you can create a combat log filter to only show events of hostile player controlled characters and have the exact same warning of enemy players that Paranoia provides. The only difference is the alarm sound, warning popup message, and targeting.

And about targeting. Way back during patch 1.08, Paranoia used to target enemies using TargetUnit(), just like many other addons. Then, with patch 2.0, Blizzard blocked many functions relating to spellcasting, target switching, etc. including TargetUnit and the original Paranoia author, rmet0815, removed targeting completely from the mod. After picking up the addon, I've recently re-added targeting to Paranoia, this time using SecureTemplates. SecureTemplates are Blizzard's way of allowing mods to continue doing things like targeting and spellcasting, while requiring some form of human interaction first. When using SecureTemplates, a mod cannot arbitrarily target another player, it requires something to be done, be it a mouseclick, scrollwheel movement, or a keypress, before it can perform the action. The way Paranoia targets an enemy is simply by creating a regular /target macro with the enemy player's name. This means that whatever /target can do, Paranoia can do. The inverse is also true. /target cannot target stealthed, invisible, or out of visible range players, and neither can Paranoia.
Q u o t e:
Might not be an exploit, but I can't quite reconcile the ability to target stealthed players from anywhere simply by clicking on their name in your mod log. That doesn't seem kosher.

/target cannot target stealthed players, and neither can Paranoia. If the player is visible and in-range, /target can target them, and therefore so can Paranoia.

Q u o t e:
Otherwise it seems legit. If the only way it is detecting stealth is through the combat log you should be ok.

If by detecting stealth you mean "Hey look the combat log says some rogue just went stealthed nearby, I better be careful" and not "Hey look that rogue went stealthed and he thinks I can't see him, activate superhax lol", which I doubt is possible because I don't think the WoW client even gets information on a stealthed player, then yes, that's the only way this addon "detects stealth".

-----
Paranoia is not a "cheat"... and I'd appreciate it if you wouldn't disparage the time and effort I've put into writing this addon by calling it one.
kthx.

Heh, PEPA, I like that =P

Localization is coming soon I hope, maybe in the next couple versions... then after that I'll have to get some translations.
Thanks for the comment, and keep up the great work with PS, it's given me many ideas =D

Paranoia is just (by design) a much simpler addon than Personal Sentry. However, since picking up the addon, I've been slowly adding features to bring it closer to addons like Personal Sentry.
I can see the addon having channel/party reporting capabilities, though I wouldn't make it automatic since the addon detects all enemies, not just those who attack you. Autotargeting is impossible now since TBC came out, but click-to-target is possible using secure frames. Unfortunately I don't know how to use secure frames, but I'm researching and click-to-target should be back in Paranoia by the next version. The hitlist would be the very last thing that I implement since it strays kinda far from the original intent of this addon and there are other addons that do the same thing better than I would be able to (Ganklist, Opium, etc.)
Thanks for the suggestions, I realize Paranoia isn't really even close to Personal Sentry but give me some time and it'll get there.
