AGL Check Script - add more units into table?

[johnv2pt0]

Can anyone help me with this?

 

I made a simple script to check a client's agl and output a message to them. Set on a continuous action trigger. It seems to work well, however I'd like to adapt it to check a table of units instead of just looking for a specific one.

 

As a bonus, I'd love to figure out how to schedule it in the script so that it only sends the message once every 20 seconds or so. I should be able to make that happen via triggers, but having it neatly wrapped up in the script would be nice.

 

--MSG TO CLIENT IF ALTITUDE > 1000' AGL
local
_SHARK1 = Unit.getByName("SHARK 1")
ALT = _SHARK1:getPoint().y
GROUND = land.getHeight({ x = _SHARK1:getPoint().x, y = _SHARK1:getPoint().z })

   if (ALT - GROUND) > 304.8 then
       trigger.action.outTextForCoalition( 2, "" .. _SHARK1:getPlayerName() .." , YOU'RE ALTITUDE IS TOO GREAT.  PLEASE REMAIN BELOW 1000' AGL FOR DECONFLICTION.", 10 )
       
   end
   
   env.info(ALT)
   env.info(GROUND)

 

Any help would be greatly appreciated!

Put this on a once condition.

timer.scheduleFunction will set that function to run again in 20 seconds.

The unitTbl is a table of unit names which gets iterated via for i = 1, #unitTbl do

 

It then checks to make sure the unit is alive.

Then stores that unit as _u

Changed alt to pos because there isnt really a need to recheck the position. Also made it local.

 

local function altCheck()
   timer.scheduleFunction(altCheck(), {}, timer.getTime() + 20)
   local unitTbl = {"SHARK 1", "SHARK 2", "SHARK 3", "Hornet 1"}
   for i = 1, #unitTbl do 
       if Unit.getByName(unitTbl[i]) and Unit.getByName(unitTbl[i]):getLife() > 0 then 
           local _u = Unit.getByName(unitTbl[i])
           local pos = _u:getPoint()
           local GROUND = land.getHeight({ x = pos.x, y = pos.z })

               if (pos.y - GROUND) > 304.8 then
                   trigger.action.outTextForCoalition( 2, "" .. _u:getPlayerName() .." , YOU'RE ALTITUDE IS TOO GREAT.  PLEASE REMAIN BELOW 1000' AGL FOR DECONFLICTION.", 10 )
                   
               end
               
               env.info(pos.y)
               env.info(GROUND)
       end
   end
end
altCheck()

Thanks Grimes! I think this will really help me understand some things better.

This works without the scheduler, but with it in I get a stack overflow. Any ideas?

 

error msg references this line:

 

timer.scheduleFunction(altCheck(), {}, timer.getTime() + 20)

[Grimes]

Oops. remove the () next to the alt check in that call.

 

timer.scheduleFunction(altCheck, {}, timer.getTime() + 20)
