Runway Denial

johnv2pt0 · March 25, 2013

Is there a way to check the health status of runways?

I have tried using MIST map object destroyed in polygon to no avail. I haven't tried SLMod but I think it's the exact same function as that in MIST.

I'm trying to make a training mission that will check a pilot's hits on a runway without using the SLMod weapons impacting in zone function. I'd like to stay away from SLMod if at all possible for maximum exportability to users. I also want to stay away from putting actual targets on the runway (troops, etc)

Am I out of luck?

If you have FC3 check out the MP mission "Su-27 - Sukhoi Surprise - Coop4"

Speed has a scoring system in there for getting hits on the runway using only Mist.

I'm pretty sure that most of the mission scripting type of functions from slmod will get ported in Mist, but that is Speeds code and that is up to him.

Thanks, I'll check it out.

Edit: I've searched all the sites I know and can't find this. Can you provide a link?

lol ok, thanks! I don't think I've fired up single player missions in years!

I've played with Speed's script a bit in an effort to learn some things and have it be more in line with what I will need for one of my missions, but I have a problem

Instead of checking 5 segments I've reduced it to 2 (west and east) and once the scoring script get's enough hits in each section it will simply turn a flag on.

do

            end
            scoreWest = scoreWest + hitScoreWest
       end

           local hitScoreWest = 0
            for i = 2, #runwayHitsEast[i] do
               hitScoreEast = hitScoreEast + hitBonus
            end

       end
	
       if scoreWest >= reqPoints then
          trigger.action.setUserFlag(westEndFlag, true)
	end
	
	if scoreEast >= reqPoints then
          trigger.action.setUserFlag(eastEndFlag, true)
	end
	
end
   
end

It's working fine for the first segment but not for the second. Where am I going wrong?

There were a couple problems. Try the attached code and see if it works.

			end		
		end
	end
end

Thanks Speed, I'll give it a go and try to learn some more poop.

EDIT: It works great, thanks again for the help

Fixed his script. The only thing I changed was the shotHandler function. But I copied the whole thing in there anyways.

do 

local runwayHits = { [1] = {}, [2] = {}, }

					local init = event.initiator
					local init_name = ''
					if init:isExist() then
						init_name = init:getName()
					end
					tracked_wpns[event.weapon.id_] = { wpn = wpn, init = init_name, pos = wpn:getPosition().p, dir = wpn:getPosition().x }
				end

Thanks Grimes! I appreciate you taking the time to fix it. I'll redirect the other thread here for people's searches.

I can't get this script to work anymore and I don't see anything wrong based on the latest MIST documentation so I'm wondering if one of the functions in DCS is broken. Would one of you smart fellas please take a min to look at this? Attached test mission and script.

Runway Bombing Detection Script.lua

BOMB ON RUNWAY TEST.miz

Grimes · June 29, 2017

It works, you just have two minor issues preventing it from working.

Two issues:

1. The zone defining the runway is was named "runwayzone #001" in the editor, the script was looking for "runwayzone".

2. You have to call the scoreMission() function because it isn't called automatically. I think the mission that used this script had a condition like Once a unit enters a zone and then exists it, it will run the scoreMission() function.

FlightControl · June 30, 2017

Maybe this is also an option? It keeps the runway healthy.
