Auto walker which can judge player/mob then fight

Hi all,

I'd like to seek for your advice on the issues I cannot resolve by myself after spent many time on trail and error.

I want to develop an auto walker which can achieve following features:

Judge if the room already has a player or mob(s) I want to kill
If there is a player entered the room before my char does, then my char will directly move to the next room
If no player in the room but the mob(s) I want to kill are there, my char will fight with the mob, then move to the next room after the mob(s) are killed

If a player enters the room later than my char, my char will continue fighting with the mob(s) in the room instead of moving to the next room

I referred to Nick's reply in this post to have the auto walker as the base (the 3rd reply)

Plus the function to judge player/mob following Nick and Fiendish's instruction in this post (thanks for the great guidance again!)

Then come out my codes as below (separate in several parts for easy reading; some words in Chinese since the MUD I play is in Chinese):

Auto walker by timer


<timers>
  <timer second="2.75" offset_second="0.00"    send_to="12"
group="潛能1" >
  <send>route_check()
pplroom = nil
EnableTrigger("check_player", true)

Note(pplroom)
Note(fighting)
Note(loc)

-- stay here if we are fighting or recovering

if fighting then
  return
end  -- if

loc = (loc or 0) + 1  -- next way to walk

  -- if past end, go to next wave
if loc &gt; #route then
  loc = 0
  pot_wave = GetVariable("pot_wave") + 1
  SetVariable("pot_wave", pot_wave)
  next_wave = pot_wave + 1
  if route_current[pot_wave] then
     DoAfterSpecial(2, 'Execute("move " .. next_wave)', 12)
  else
     route_check()
     Execute("move 1;exert force;deposit 10000 coin")
     DoAfterSpecial(8, 'Execute("deposit 100 silver")', 12)
     --DoAfterSpecial(8, 'Execute("w;s;w")', 12)
     loc=0
     timer_end("潛能1")
     --timer_start("練武")
  end -- if
else
  DoAfterSpecial(1, 'Send(route [loc])', 12)
  Note(fighting)
end -- if</send>

  </timer>
</timers>

Trigger used to judge player/mob then define "fighting" is true of false


<triggers>
  <trigger
   group="查玩家"
   match="^[&gt; ]*.*\((?P&lt;char_name&gt;.*)\).*$"
   name="check_player"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>Char_Name = string.lower("%1")

pplroom = find_in_list(Char_Name, players)

if pplroom then
   fighting = false
   Note ("Warning, player " .. pplroom .. " here.")
   EnableTrigger("check_player", false)
   return 
else
   mobroom = find_in_list(Char_Name, mobs)
   if mobroom then
      fighting = true
      Execute ("say Mob " .. mobroom .. " here.")
      EnableTrigger("check_player", false)
      timer_end("潛能1")
   else
      fighting = false
   end -- if
end -- if</send>
  </trigger>
</triggers>

Trigger to re-active the timer


<triggers>
  <trigger
   custom_colour="2"
   enabled="y"
   group="統計"
   match="^吒]為你殺死了(.*)，得到了\s+(\d+)點經驗值和\s+(\d+)點潛能以及\s+(\d+)點聲望。$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
<send>
-- check state --
EnableTrigger("check_player", true)
check_state ()
DoAfterSpecial (0.5, 'heal()',12)
DoAfterSpecial (0.75, 'pot_threshold()',12)
timer_start("潛能1")</send>
  </trigger>
</triggers>

Some self-defined functions used (less relevant ones are excluded)


function find_in_list(find_what, the_list)
   for k, v in pairs(the_list) do
      if find_what:lower() == k:lower() then
         return k
      end -- if
   end -- for
end -- function


function pot_threshold()
    if my_pot > 150 then
       timer_end ("潛能1")
       -- trigger_end ("潛能1")
       fighting = false
       loc = 0
       Execute ("move 1")
       DoAfterSpecial (1, 'timer_start("學習")',12)
    else
       Execute ("look")
    end -- if
end -- function


function frozen_blade()

    Execute ("wield blade;perform blade.kill;unwield blade")

end -- function

Issues bumped

The walker usually works fine, while sometimes it makes my char move to the next room when the fighting is still on-going
Once my char moves as mentioned in #1, since the walker has already been temporarily turned off, my char will be idled there until the timer is fired by another trigger after 15 mins
If another player enter the room after my char, when my char sees the player, the timer will move my char into the next room - this is not the ideal behavior I want

May I have your help/guidance on the possible solutions? Thanks in advance.
