Training SAMs by Grimes

[Grimes]

It should work for any guided A2A or surface to air missile. I didn't change enough for it to break. Which aircraft/weapons are you using and are you sure the script is loading before shots are fired? Just to humor me, put it on a Once>Time Less than 5>Do Script trigger. That is how I had it setup when I tested it earlier.

[Eddie]

It's certainly loaded, dcs.log confirms it. Initially tested with an A-10C vs SA-3/SA-6 and loading file a once>time more than 5>do script file trigger.

 

I've switched it to your trigger format and the same occurs, it does however work vs SA-15/SA-8/SA-13 in both cases. So, it appears there may be something related to the missiles themselves (class/type issue perhaps)?13

[Grimes]

After some investigations I've figured out the problem. Got sidetracked by slmod and general tester stuff so I haven't made the fixes yet. I'm also going to make it a little more configurable so you can easily set it to destroy player missiles or not. Also I forgot I had put this script up on my github as part of my miscScripts repository, so I am going to be editing my older posts in this thread and just link directly to the script file there.

[Eddie]

Outstanding. The effort is massively appreciated.

 

Out of curiosity, can you explain what the issue was (in simple terms if possible, preferably with crayons)?

[Grimes]

I was going to get my wacom tablet out to try and draw it, but it dawned on me that illustrating how code works would probably take to much time to figure out a decent way to do it.

 

The short of it is that I over simplified the code. Specifically it just needs to check the distance to target more often and without much of a delay built in. It was written with sam sites in mind so certain assumptions like estimated time to impact were made and relied upon to define when to check each weapons position. These assumptions made the script not work with shorter range shots, which is something I didn't realize at first. Upon tweaking the numbers for shorter range shots it screwed up longer range shots.

[Eddie]

Gotcha, makes sense.

 

Again out of curiosity, and because I keep being asked about it myself when explaining this script to people, is a similar script possible for guns/aaa etc? My instinct is no, but as I only just know enough to tweak parameters in other people's scripts I'm reluctant to say for sure.

[Dojo]

Grimes, I have nothing valuable to add to the discussion, other than to say that this is the thing I'm most excited for coming to the sim at the moment.

 

Now go make us proud, you coding freak of a man.

[Hansolo]

Oh this is excellent new Grimes. We had this running in our old tranining mission and yes we 'lost' a pilot during this because the ground force commander was firing missiles at and A-10C.

 

Would be awesome if you got it working Sir :thumbup:

 

Cheers

I'm pretty certain shells can be destroyed, its just a more complex process overall. There are a lot more objects to track and getting those objects isn't as simple as using a lone event handler. Determining a hit would also require a bit more math since its not a single object that explodes once near the target, its dozens-hundreds of objects that have to physically intersect with the target. It can be done, I just don't know how practical it would be. At its simplest it may be possible to do a very rough approximation of the shells trajectory to determine a hit and simply destroy the shells as soon as possible. So you'd have to have ammo for it to work and firing the gun would result in a "simulated" shot.

[Eddie]

Hmmm interestin, thanks. It I can ever find the time to wrap my head around lua I might make that a project.

[Eddie]

Grimes, any idea when you'll be able to put some time into this one? I know it's not the most used script and with everything else it'll be way down the to do list, but it would be greatly appreiced by us at least.

[ESAc_matador]

Grimes.

 

After your recomendation of start learning lua a year a ago.. Now I am in the middle of the process, i did cool scripts to my squadron, and now I want to make something different, but I am not very good at event handlers. So I want to identify Radar Guided missiles, and using this script, "emulate" some electronic warfare, comparing the distance with a specific aricraft/s that will be the Jammers.(Prowlers)

 

So, what I need is,

 

if

missile distance to Prowler unit <= 500m then missile (Radar Guided) has 90% probability of missing ( explode).

elseif

1000m >= missile distance to Prowler unit and >500m then missile (Radar Guided) has 50% probability of missing ( explode).

1500m >= missile distance to Prowler unit and >1000m then missile (Radar Guided) has 25% probability of missing ( explode).

 

I ll check the distances, later.

 

 

What i get with this?? Well, it means that all aircrafts that are close to the Prowler are protected against the missiles. I just want to compare the distance between missile and specific unit.

 

I know I can get the position of the units or objects via getPos etc, but I dont know how to identify them so I an make the script.

 

I have been checking your script but.. I dont know what I should really do.

 

I think if I change...

 

local dist = get3DDist(Object.getPoint(mis.missile), Object.getPoint(mis.origTarg))

for

local dist = get3DDist(Object.getPoint(mis.missile), Object.getPoint(Unit.getByName('Prowler'))

 

What do you think?

 

and then changing the conditions... but I am quite lost here... any advice? or help please??

 

It would be nice to make interdiction missions with F5 or Mirages... depending on flying under the plan to survive and see missiles launched everywere...

[Grimes]

Well when the missile is fired there is the weapon object which you can use Object.getDesc() on to figure out information about it. You'd be looking for a weapon category of missile, a missileCategory of AAM, and missileGuidance of Radar active or radar semi active.

 

I think you are on the right track. Something to know about this little script is that I have it setup to recheck the missile position the closer it is to a target. So if you used your above psuedo code for removing the missiles, then it would be EXTREMELY likely that the missile gets removed. Its written in a way to 100% remove a missile that gets close for training purposes.

Hi Grimes,

 

this script is so awesome, found it just yet. How's the status on client vs. client (A/A) situations? Does ist work, now?

[Grimes]

It didn't work before? There is a little option I added for that: trackAIShotsOnly. It should work, haven't exactly tested it in a while.

[ESAc_matador]

I am trying to make it work with no success...

 

I just put an A10, with an enemy Tor. I receive the message where says that I should have ejected, but the missile didnt explode, instead it hit me.

 

Can anyone pass me a mission that works?? and if possible the lua file they are using?

 

Cheers.

 

PS: I think, I know how to make the Jammer Script.

[VTJS17_Fire]

Thanks Grimes, will try it.

 

@Matador: Good to know, I'm looking forward.

[ESAc_matador]

Fire, if you have a mission and a script working, please send it to me or post it

[VTJS17_Fire]

Wilco.

[Midnight]

Tested and works for the SA-3, SA-8 but the SA-10 kills you. I have not tried other systems.

[ESAc_matador]

Ups... I have been doing tests with tor

[ESAc_matador]

Can you post the mission Midnight?? it does not work for me at all.

[Midnight]

I do not have a mission yet for the Caucasus map and can make one for you, in the meantime you can see it in action on the DCS 2 NTTR VSAAF Training mission. The test area is at Mesquite.

[ESAc_matador]

I ll see.

 

Thank you!!!

[Midnight]

here you go, give that a try. For the Caucasus map.
