Lua debug log ?

[lanmancz]

edit:

ah, I got it. Turns out that the DUMMY unit cannot be marked "dead" or else the Unit.getByName() returns nil. That was the problem. So I created immortal standard unit and now it's ok. I knew it had to be something stupid like this :-)

 

So this now works ok. I expanded it a bit so it also reports hits. Thanks for the debug tips though guys!

 

local StaticTargetName = "DUMMY"
local DetectionRange = 500
local ShotEventHandler = {}
local HitEventHandler = {}
local isHit = "----"
local lastDistance = DetectionRange
function HitEventHandler:onEvent(event)
   if event.id == world.event.S_EVENT_HIT then
       if event.target == Unit.getByName(StaticTargetName) then
           isHit = "HIT!"
           local _ordnanceName = ""
           if event.weapon ~= nil then
               local _ordnance = event.weapon
               _ordnanceName = _ordnance:getTypeName()
           end
               
           local _initname = ""
           if event.initiator ~= nil then
               local _initiator = event.initiator
                   _initname = _initiator:getPlayerName()
               if _initname == nil then
                   _initname = _initiator:getName()
               end
           end            
           
           trigger.action.outText(isHit.."     Who: ".._initname.."     What: ".._ordnanceName.."     Distance: "..lastDistance, 10, true)
       end
   end
end

function ShotEventHandler:onEvent(event)
   if event.id == world.event.S_EVENT_SHOT then
       isHit = "----"
       lastDistance = DetectionRange
       local _ordnance = event.weapon
       local _ordnanceName = _ordnance:getTypeName()
       local _initiator = event.initiator
       local _initname = _initiator:getPlayerName()
       if _initname == nil then
           _initname = _initiator:getName()
       end

       local TrackShot = {}
       function TrackShot()
           if _ordnance:isExist() == true then
               local _sP = _ordnance:getPoint()
               local _staticTarget = Unit.getByName(StaticTargetName)
               local _tP = _staticTarget:getPoint()
               local _distance = math.floor(math.sqrt(math.pow((_sP.x - _tP.x), 2) + math.pow((_sP.y - _tP.y), 2) + math.pow((_sP.z - _tP.z), 2)))
               if _distance < lastDistance then
                   lastDistance = _distance
               end
               
               if _distance < DetectionRange then
                   trigger.action.outText(isHit.."     Who: ".._initname.."     What: ".._ordnanceName.."     Distance: "..lastDistance, 10, true)
               end

               return timer.getTime() + 0.005
           end
       end
       timer.scheduleFunction(TrackShot, nil, timer.getTime() + 0.5)        
   end
end

world.addEventHandler(ShotEventHandler)
world.addEventHandler(HitEventHandler)

Lua errors are logged to %USERPROFILE%\Saved Games\DCS\Logs\dcs.log

 

You can also use env.info("my message") to write your own entries to that log file.

 

Another great way to debug Lua code is the Lua Console in DCS Witchcraft (link in my sig), which lets you execute snippets of Lua code inside a running mission.

I used SNAFU's one and it works perfectly in DCS 1.5. Not sure how yours is different or what you need from the script.
