detectClient code -- help needed

[Wrecking Crew]

Hi, thanks for taking a look, trying to detect when clients take off. The Flag 50003 is supposed to go True on an S_EVENT_TAKEOFF. I cobbled this code from examples so there may well be something wrong, but it is not throwing errors, testing it in Single Player DCS v1.5.4. I did try different means for setting Flag 50003 to True and 1, and using just 'F-15C 01' for the player name but no joy. Appreciate any help.

 

do
local function detectClient(event)
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  local airborneUnit = event.initiator
  if(Unit.getPlayerName(airborneUnit) == {'F-15C 01', 'F-15C 02', 'F-15C 03', 'F-15C 04','M-2000C 21', 'M-2000C 22', 'M-2000C 23', 'M-2000C 24'}) then
   trigger.setUserFlag(50003, 1)
  end
 end
end
mist.addEventHandler(detectClient)
end

 

The Player names are in the 'Pilot' field for the Client a/c.

  if(Unit.getPlayerName(airborneUnit) == {'F-15C 01', 'F-15C 02', 'F-15C 03', 'F-15C 04','M-2000C 21', 'M-2000C 22', 'M-2000C 23', 'M-2000C 24'})

 

Unit.getPlayerName returns only a string, not a table. This condition won't ever be true. :)

 

Something like this maybe:

do
local function detectClient(event)
 local function contains(tbl, val)
   for _,v in ipairs(tbl) do
  if v == val then return true end
   end
   return false
 end
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  local airborneUnit = event.initiator
  if(contains({'F-15C 01', 'F-15C 02', 'F-15C 03', 'F-15C 04','M-2000C 21', 'M-2000C 22', 'M-2000C 23', 'M-2000C 24'}, Unit.getPlayerName(airborneUnit))) then
   trigger.setUserFlag(50003, 1)
  end
 end
end
mist.addEventHandler(detectClient)
end

Thanks, had high hopes this would do it. Once this works I will be able to do lots more.

 

This did not work for player F-15C 01 in Single Player test:

do
local function detectClient(event)
 local function contains(tbl, val)
   for _,v in ipairs(tbl) do
    if v == val then return true end
   end
   return false
 end
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  local airborneUnit = event.initiator
  if(contains({'F-15C 01', 'F-15C 02', 'F-15C 03', 'F-15C 04','M-2000C 21', 'M-2000C 22', 'M-2000C 23', 'M-2000C 24'}, Unit.getPlayerName(airborneUnit))) then
   trigger.setUserFlag(50003, 1)
  end
 end
end
mist.addEventHandler(detectClient)
end

 

 

The mission is attached. The event is the 4th one down, 'mist.detectClient'

 

The help is appreciated. :beer:

Do the number of spaces/tab vs spaces make a difference between working code and not? There are two spaces in the function 'contains' instead of one.

Making progress, this code detects the take off of the F-15C and sets the flag and outputs the text but when I quit the mission the following error appears. Why this error?

 

do
local function detectClient(event)
 local airborneUnitName = event.initiator:getName()
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  trigger.action.setUserFlag(50003, true)
  trigger.action.outText(airborneUnitName .. ' just tookoff!', 5)
 end
end
mist.addEventHandler(detectClient)
end

do
local function detectClient(event)
 local airborneUnitName = event.initiator:getName()
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  trigger.action.setUserFlag(50003, true)
  trigger.action.outText(airborneUnitName .. ' just tookoff!', 5)
 end
end
mist.addEventHandler(detectClient)
end

 

When you quit the mission an event is triggered(S_EVENT_MISSION_END) as well

Event = {
 id = 12,
 time = Time,
}

this event, however, does no have an "initiator".

 

In your code you did

local airborneUnitName = event.initiator:getName()

before the if clause. Try to simply place this line into the "if"

do
local function detectClient(event)
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  local airborneUnitName = event.initiator:getName()
  trigger.action.setUserFlag(50003, true)
  trigger.action.outText(airborneUnitName .. ' just tookoff!', 5)
 end
end
mist.addEventHandler(detectClient)
end

so that when you quit a mission, an event is triggered and event handler does your function. It goes to the if, only to find that the event is not a takeoff event; then it stops there and leaves no scripting error

Makes perfect sense -- that solved the error, thank you! Now to extend the logic to detect the takeoff of specific a/c who are Clients...

[Wrecking Crew]

Got it! Thank you guys. Here is the tested code and simple mission. The outText line is only for testing.

 

do
local function detectClientTakeoff(event)
 local function contains(tbl, val)
  for _,v in ipairs(tbl) do
   if v == val then return true end
  end
  return false
 end
 if(event.id == world.event.S_EVENT_TAKEOFF and event.initiator) then
  local airborneUnitName = event.initiator:getName()
  trigger.action.outText(airborneUnitName .. ' just tookoff!', 5)
  if(contains({'F-15C 01', 'F-15C 02', 'F-15C 03', 'F-15C 04', 'M-2000C 21', 'M-2000C 22', 'M-2000C 23', 'M-2000C 24'}, airborneUnitName)) then
   trigger.action.setUserFlag(50003, true)
  end
 end
end
mist.addEventHandler(detectClientTakeoff)
end
