Hello,
 
You have lua functions GetRaidTargetIndex and SetRaidTarget (or SetRaidTargetIcon)
 
Samples:
 
Launch the spell id 109259 on the first boss with skull icon:

local SpellName = GetSpellInfo(109259) for i = 1, 4, 1 do local UnitIdString = "boss" .. i if UnitExists(UnitIdString) then if GetRaidTargetIndex(UnitIdString) == 8 then CastSpellByName(SpellName, UnitIdString) return end end end Launch the spell id 109259 on the first raid target with skull icon (this code check the target of raid members):
local SpellName = GetSpellInfo(109259) for i = 1, 40, 1 do local UnitIdString = "raid" .. i .. "target" if UnitExists(UnitIdString) then if GetRaidTargetIndex(UnitIdString) == 8 then CastSpellByName(SpellName, UnitIdString) return end end end Launch the spell id 109259 on the first party target with skull icon (this code check the target of party members):
local SpellName = GetSpellInfo(109259) for i = 1, 4, 1 do local UnitIdString = "party" .. i .. "target" if UnitExists(UnitIdString) then if GetRaidTargetIndex(UnitIdString) == 8 then CastSpellByName(SpellName, UnitIdString) return end end end ps: Replace 109259 by your spell id and add conditions to launch the spell, to launch the spell if mob health is lower than 50%:

local SpellName = GetSpellInfo(109259) for i = 1, 4, 1 do local UnitIdString = "party" .. i .. "target" if UnitExists(UnitIdString) then if GetRaidTargetIndex(UnitIdString) == 8 then if UnitHealth(UnitIdString)/UnitHealthMax(UnitIdString)*100 < 50 then CastSpellByName(SpellName, UnitIdString) return end end end end ps2: Code no tested, do not hesitate to tell me if this don't works

Hello,   Wait next update, the problem has been caused probably because this condition counted only mobs in combat with your character and not in combat (mobs in combat with party members are ignored). I have fixed it, now all hostile mobs are count.   Tell me if you problem is resolved with next update. 

It works fine in wrotation, but not in grinder, because the mobs mostly doesn't stand still in the trap (i.e. Talbuks) You need the barn in your Garrison It's optional and off by default You need to add the ID of the mobs you want to catch to the Variable KillBeast. (wowhead.com and the Development tools/Target Info will help)

I dont really think that this is the most urgent issue to adress but still worth of some improvement.
I also would appreciate to have a more sophisticated option to deal with open world pvp. Although in most cases, i dont believe that just ignoring an attacker is an appropriate option. Just standing there and getting killed is also not the best option.
Being able to chose from some options like 
- fight back,
- ignore and carry on with whatever i do,
- do nothing and take the beating or
- flee run from it (my favorite)
would be what i would appreciate.

I prefer having an API documentation...

Thanks for that. It helps much. I've created a Stratholme Profile based on yours.

Hello,
 
For advanced user:
- You can found sample of dungeon profile http://wrobot.eu/files/file/453-dungeon-the-temple-of-atalhakkar/ file description to get more informations) and https://wrobot.eu/forums/topic/3552-dungeon-profile-creation-tutorial-video/
 
For beginner users:
- Install and activate this plugin: http://wrobot.eu/files/file/496-reset-instances/
- In "General Settings", disable option "Close bot if teleported".
- Select product "Gatherer" or "Grinder" and activate option "Back to last profile position" in "Product Settings".
- Now, use "Profile Creator" and record loop path (in your loop, go out of instance) (You can download gatherer profile sample of "Hellfire Ramparts" here) (you can use "Action" to add feature at your profile)

Sorry, i cant. I only post the (imho) best solution. If you want to get the old solution change only
 
 
if (GetUnitSpeed("player") == 0) and not (UnitCastingInfo("player")) and not (UnitChannelInfo("player"))
 
with
 
if not (UnitCastingInfo("player"))
 
 
GCD is simple to detect. Use Parameter "Is Spell usable" in the fight class editor.
 
in lua try something like this
local spellid=123456 --[[change to the ID-nr of the spell)]] local spellname=GetSpellInfo(spellid)                 if (IsUsableSpell(spellname)) then                     local start, duration, enable = GetSpellCooldown(spellname)                     if (duration==0) then                         CastSpellByName(spellname);                         spell=spellname;                         break;                     end                 end

Thats right. in the log you only see "--buffs", because in the log you see only the name of the "spell." In this case the lua script ist the "spell" and named "--buffs"
 
You have to change the for-loop variable form 6 to 11 (if I count your buffs right)

The following Code is a LUA-Script without a LUA-Script with a LUA-Condition that never wil be true. And it works fine! :-)
 
1.) Lua Script Spell.
With a Lua Script we can use our own fantasy Spell name, instead of a real script, because Lua Scripts are bad to be supported (insert,delete,insert) and they are very ugly in the settings window. So we use only the Word "--Buffs" as lua script. Because we don't have a real LUA script here, we use the comment signs "--" . (see note below the code)
 
2.) Lua Script Condition.
This do the work. The script do all needed checks for the buffs. It checks, if we are in combat (at least 1 Combo Point at a living and exiting target.) and then it check if the buffs (idBuffs) are known and cast them if they needed. The local variable buffed is only needed for debugging.
    <FightClassSpell>       <SpellName>--Buffs</SpellName>       <FightClassConditions>         <FightClassCondition>           <ContionType>LuaScript</ContionType>           <Param xsi:type="FightClassConditionLua">             <LuaScript>local buffed=0 if UnitExists("target") and not UnitIsFriend("player", "target") and not (UnitIsDead("target")) then     comboPoints = GetComboPoints("player", "target")     if (comboPoints &gt; 0) then --[[                Adrenalin,Combat Readiness,Shadow Blades,Berserking,lifeblood,Blood Flurry ]]         local idBuffs={13750,74001,121471,26297,121279,20572}         local idStealth=1784         local spellname=GetSpellInfo(idStealth)         local start, duration, enabled = GetSpellCooldown(spellname)         if (enabled==1) then             for i=1, 6 do                 if (IsPlayerSpell(idBuffs[i])) then                     local start, duration, enabled = GetSpellCooldown(idBuffs[i])                     if (duration==0) then                         local spellname=GetSpellInfo(idBuffs[i])                         CastSpellByName(spellname)                         print("buff: "..spellname)                         buffed=buffed+1                     end                 end             end                      end     end end result=(buffed&gt;0) </LuaScript>             <VarRet>result</VarRet>             <ValueRet>true</ValueRet>           </Param>         </FightClassCondition>       </FightClassConditions>       <Priority>23</Priority>       <AddToSettings>true</AddToSettings>       <NotSpellIsLuaScript>true</NotSpellIsLuaScript>       <DescriptionSpell>Set all known buffs</DescriptionSpell>     </FightClassSpell> based on WoW 5.4.2.
 

 
Note:
 
In a previous version I use "Buffs" instead of "--Buffs". I changed this to get an entry in the log-file. If you dont like "--Buffs" in the settings window, you can change it back to "Buffs" (or what ever you want). But then you have also change "<ValueRet>true</ValueRet>" to "<ValueRet>notNeeded</ValueRet>". You don't get any logfile entrys in this case, but the script works fine.

look here (in Fight Class Assistant)

I think I found the solution. Could it be, that you only check UnitCastingInfo("player") ?

This fails if it is a spell like mounting. Please have a look at UnitChannelInfo("player").

The difference between this I describe here

http://www.wowhead.com/item=40768
 
Moll-e is a item that engineers could create and use. The item must be in a bag. The handling is like a normal mailbox. And like a normal Mailbox it isn't possible to get the item in target.
I see a different Item name in the minimap, but I dont use a english client.
 
the spell www.wowhead.com/spell=54710 create an objet with the ID 191605

By default, this solution cast a lethal and a non-lethal poison, depending of the knowledge and the priority-list (idPoisons[1]=lethal, [2]=non-lethal).  If there is already a poison, and the run time of the poison will be less then 13  min, it will be renewed, if we are 
not in combat. (We need it before) not AFK (who want casting while afk ?!?) not Falling, Flying or Riding (mounted) (flying + casting = falling) not casting Why 13 Minutes ? Because of the duration time of a fight with a raid boss. You want more or less ? Change  the 13 in  local timeLeftToCastAgain = 13*60 to another value.

At first: The talent "Marked for Death" is needed to use the spell "Marked for Death". Without them, only the Redirect spell will be used.
 
1. Check if there are any combopoints around there, but not on the target. In this case we use Redirect if possible.
2. If Redirect is not usable, then we use "Marked for Death". which give us 5 CP instant. (accept Shadow Blades is active.)

The "Combat" detection isn't usefull in all cases. Because of this I select a target in Raids only if i am sure that the fight has startet (or the pullcountdown will be 0). And I wait for the first CP to start the buffs, debuffs etc to be sure, that I am in fight to. It lose (very little) DPS, but I am sure, that I dont pull the boss or that my buffs are running out without an impact

This snippet needs the snippet or another solution to handle Cheap Shot
 
What do we do ?
We check, if the target is stuned. If not, we try a Kidney Shot, If Kidney Shot not ready AND we are in PvP OR in a Group AND attack the same Mob AND Vanish and Cheapshot are ready we vanish. ...(and now?)... Your (or my ()) Cheap Shot solution do its best to stun again. We remember Preparation...and use it. And we start at point  3. again After this Kidney Shot should be ready again. (20 sek cd) I use Kidney Shot with 4 or more Combo Points. If you want it faster, change the value after GetComboPoints (btw: do you know Nerve Strike ?)

"I want to break free" (Queen). In this case we want to break out of stealth. In PvP this will be most done with Cheap Shot , in PvE with Ambush . Ambush will only work, if you are behind the target. Because we couldn't not really be sure, that we are behind the target, I use a shadowstep before, (and a pickpocket. We have it, we should use it ;-) ).
 
If Ambush is not usable (not more behind or spell not known), I try Cheap Shot, Garrote,  Revealing Strike and at last Sinister Strike to get out of Stealth into combat.

For Rogue (mostly Combat Rogue) :
 
(Discussions about the snippets in the correspondending Threads)
 
Set your poisons out of combat. Manage Redirect and Marked for Death : Use all 4 abilitys to kick a spell. Kick, Blind, Gouge, Kidney Shot. (and Feint, if it is not kickable) : All buffs at once : From Stealth to Combat. Cheap Shot / Ambush, Garotte, Revealing Strike, Sinister (one of them do the job) needs . Cheap Shot (stun), Kidney Shot (stun), Vanish, Cheap Shot (stun), Preparation, Vanish, Cheap Shot (stun), Kidney Shot (stun). I'am sure, your opponent will love you for this ;-) 10 /use 13 and /use 14 . 30 Yards ! and no step closer...bye!  
How to use the snippets: (looks more then it is)
click on the snippet you want mark the whole code (from <FightClassSpell> to </FightClassSpell>) CTRL-C (copy the marked code) . Go to your mrobot directory open the fight class folder right click on the file do you want to edit Edit (or Edit with Notepad++, if you use Notepad++) Go to the last line CTRL-V (append the code to your fight class) Save the new code . start the Fight Class editor open the changed fightclass move the new spell to the right place in the priority list The Codes above are mostly LUA-Scripts without a LUA-Script with a LUA-Condition that needs never to be true. And they work fine! :-)
 
1.) Lua Script Spell.
With a Lua Script we can use our own fantasy Spell name, instead of a real script, because Lua Scripts are bad to be supported (insert,delete,insert) and they are very ugly in the settings window. So we use only a "--Short Description" as lua script. Because we don't have a real LUA script here, we use the comment signs "--" .
 
2.) Lua Script Condition.
The script here do the whole work. The local variable result is only needed to get a log-file entry. See also.

A (Combat) Rogue has at last 4 spells to interrupt spells: Kick, Blind, Gouge, Kidney Shot. Not all are usable in all situations, but all have the same conditions to try a try:
  the target must not be friendly its cast must be a interruptable spell our spell must be ready to use and the target must be in range. (added) If the spell not interruptable, cast feint (and hope the best) Kick need a high priority, feint a low, so I removed it with this information we could combine this 4 spells to one cast, which
make our fight class profile smaller, make the settings clearer gives a info of the spell, which is interrupted allow us to do changes in the source once, not four times Hint: With the talent "Dirty Tricks" the cost of blind and gouge are 0 energie (like Kick)

I use the spell option "Not a spell, is lua script" to use a fantasy spell name.
 
A timer wouldn't work because
 
the duration/cd could be changed, because of items (i.e http://ptr.wowhead.com/item=102292) or other buffs the buffs have CD the buffs should be available at fight start.  
And the solution above do a good job
