Script Example requiring supplies delivered via crates to airfields

[RotorVR]

I am curious, are there any good examples out there of a script that enables tracking of a supply count for an airfield or FARP that is provided by crate delivery?

 

-track supply value for an airfield 

-add to supply value with delivering crates and despawning said crate once delivered

-subtract from supply value with takeoff event and add with landing event

 

I see lots of servers do this and for our little private scenario in a small group I’d prefer to avoid trying to build something from the ground up. Does anyone have any good example that they could reference or would be willing to share?

 

I experimented using CTLD’s crate counter function and associating that with a flag value that I associated with an airfield but I think most scripts use a table value instead of flag counters and it counts any crate whether it’s a proper supply crate or a humvee crate. I don’t know any scripters to bounce ideas off of.

Here is the code I was using. Even if unwilling to share example scripts that others may have worked hard on, I'd love if I could get any help on my work:

 

THIS WORKS: I used CTLD's built-in functions to spawn a crate via standard DCS trigger and DO Script:
ctld.spawnCrateAtZone("blue", 2701, "Crate Factory TEST") --spawns a BLUE coalition HMMWV at the trigger zone "crateSpawnTrigger"

 

THIS WORKS: I used CTLD's built-in functions to designate a trigger zone to be a crate dropzone and count every 5 seconds via normal DCS trigger Do Script:

ctld.cratesInZone("Crate Dropzone TEST",200)

 

THIS WORKS: I tried editing CTLD's crates in zone function as per below so that it adds to the flag value rather than just counting and replacing the value. I got that to work, so it is now adding onto a current flag value cumulatively. I had it pull the value and add 2 to it for every crate in the zone.

 

NEED HELP: My attempts to have the crate despawn immediately following it being counted is not working. I have marked the line in bold in the code quote below.

NEED HELP: The message to all to announce the delivery and supply count is also not working. I have marked the line in bold in the code quote below.

Quote

--Script File to add function:
-- Continuously counts the number of crates in a zone and sets the value of the passed in flag
-- to the count amount
-- This means you can trigger actions based on the count and also trigger messages before the count is reached
-- Just pass in the zone name and flag number like so as a single (NOT Continuous) Trigger
-- This will now work for Mission Editor and Spawned Crates
-- e.g. ctld.cratesInZone("DropZone1", 5)
function ctld.cratesInZone(_zone, _flagNumber)
    local _triggerZone = trigger.misc.getZone(_zone) -- trigger to use as reference position

    if _triggerZone == nil then
        trigger.action.outText("CTLD.lua ERROR: Cant find zone called " .. _zone, 10)
        return
    end

    local _zonePos = mist.utils.zoneToVec3(_zone)

    --ignore side, if crate has been used its discounted from the count
    local _crateTables = { ctld.spawnedCratesRED, ctld.spawnedCratesBLUE, ctld.missionEditorCargoCrates }

    local _crateCount = trigger.misc.getUserFlag(_flagNumber) --Orignal value was 0, trying to set this to equal the current flag value

    for _, _crates in pairs(_crateTables) do

        for _crateName, _dontUse in pairs(_crates) do

            --get crate
            local _crate = ctld.getCrateObject(_crateName)

            --in air seems buggy with crates so if in air is true, get the height above ground and the speed magnitude
            if _crate ~= nil and _crate:getLife() > 0
                    and (ctld.inAir(_crate) == false) then

                local _dist = ctld.getDistance(_crate:getPoint(), _zonePos)

                if _dist <= _triggerZone.radius then
                    
                    _crateCount = _crateCount + 2 -- Crate addes value of 2 to the count which should be current flag value
                    
                    trigger.action.outTextForCoalition(_heli:getCoalition(), ctld.getPlayerNameOrType(_heli) .. " delivered a Supply Crate. Supplies at " .. _zone .. ": " .. _crateCount, 10)  --This will send a message confirming delivery and current new supply count at triggerzone
                    
                    --_crate.crateUnit:destroy() --Attempting to ADD IN THE DESPAWN CRATE LINE HERE, so crate will add 2 to flag value in line 810 but then disappear not be counted again        
                end
            end
        end
    end

    --set flag stuff
    trigger.action.setUserFlag(_flagNumber, _crateCount)

    -- env.info("FLAG ".._flagNumber.." crates ".._crateCount)

    --retrigger in 5 seconds
    timer.scheduleFunction(function(_args)

        ctld.cratesInZone(_args[1], _args[2])
    end, { _zone, _flagNumber }, timer.getTime() + 5)
end

 

If anyone can help me with the message line and the despawn line I would be really appreciative! If I can get the despawn(destroy) line to work and the message to work then I'll have the crate supply delivery functioning! I would love any help at all.
