MIssion Scripting Tools (Mist)- enhancing mission scripting Lua

[chromium]

Hi Grimes, an info: I would like to use teleport to move some groups from a remote poiint tp an urban area with a great distribution (i.e. imagine a trigger zone over Krasnodar having a radius of 3 km).

 

Is there a way to prevent units, vehicles in particoular, to be teleported over buildings?

[Wrench]

I'm having an error in call utility functions. Any function with utils in the name I get a nil value error. Such as

 

mist.utils.converter

 

I get

 

attemp to call 'converter' (a nil value)

 

As I say, I've tried a few utils, and get similar results.

Have the utilities been removed?

 

**Added**

 

Is there a way to basically combine mist.message.add and DCS func radioTransmission?

What I'd like is to use MiST's excellent multSound capability, but only over a specified frequency, like you can with radiotrasnmission.

Thanks as always! :pilotfly:

Converter should be working, but keep in mind I never actually got around to pushing that built out of the "development" branch. So make sure you are using a file from here: https://github.com/mrSkortch/MissionScriptingTools/tree/development

 

As for the radio transmission, I think it would be doable. It would be an extra set of parameters on an already complicated scripting function though. Radio transmissions are quite separated from triggered messages and sounds, so I'd be more inclined to create a new function to do it. I probably would give it the ability to do transmissions from units if desired. I've got the perfect mission to test it out on.

 

 

Chromium, I'll look into it. As a quick fix you could probably make the units drive a little bit. If they spawn on a building, whenever the unit moves it gets teleported back to ground level. It might be a complicated mess in the future due to all the new trees on Caucuses and the tree positioning isn't exactly detectable.

Thanks, Grimes. I'll have to look into the dev branch.

That's the point. May I suggest you to check y value of the spawned unit, if it's > than land.getHeight you might assume that you're not on ground level (wouldn't work for bridges.. but could be feasible?). I might move the units but doing so I would lose larger "disperse" parameter.

[Grimes]

You can also easily validate the returned units and either try it again or if applicable just remove the offending unit.

 

That isn't a solution I'd prefer to do within mist because it could be kind of resource intensive. I'd prefer to try and figure out if an object is in a building before it even spawns. I have one idea worth trying out that I am experimenting with right now. Part of the problem is that you can detect buildings near a point, but you don't know a whole lot about the shape of a building. Its sadly not a simple pointInPolygon test as there isn't a polygon to test. Suppose I could build

or ask ED for a 2d point DB of assorted world objects.

[chromium]

or else you might try to run a world.search on Scenery object for a 5 m radius for each unit placement. But sounds like calculation intense even writing it...

try to use it in dcs 2 ti get a string error as soon as mission is un paused any thoughts?

I need to know what the error is. Copy paste the error that is in dcs.log.

[Darkfury]

Apologies, this is probably a dumb question. It's my first DCS script I am trying, let alone MIST. I just want to output a different message to two pilots for a training mission. Whatever I seem to do, both client aircraft receive both messages despite them being called 'Pilot01' and 'Pilot02' and using the below code.

 

Mist is running at startup and I get no errors so I think all is well with that.

 

Maybe I have a scope problem? I don't yet have my head around scoping in DCS or LUA. Any ideas? This is in DCS 1.5.8 latest build.

 

 

   local msg = {} 
   msg.text = 'Your callsign for this sortie  is COLT 1-1' 
   msg.displayTime = 10  
   msg.msgFor = {units = {'Pilot01'}} 
   mist.message.add(msg)


   local msg = {} 
   msg.text = 'Your callsign for this sortie  is COLT 1-2' 
   msg.displayTime = 10  
   msg.msgFor = {units = {'Pilot02'}} 
   mist.message.add(msg)

I thought I'd run that through a quick mission to see if anything obvious stood out. Funny thing, I can't output any message with that script. And I see it is literally the exact syntax demonstrated at the Hoggit wiki.

 

MIST loads fine; I can see that in the logs. But I cannot get a message to ouput. I've tried various conditions, "time more", UNIT IS ALIVE, etc....but nothing outputs a message. I have the units named properly.

 

A workaround would be to make the planes single-unit groups, with group and unit names the same, then use the native "MESSAGE TO GROUP" to output the message.

 

If you have a single group with two individually named aircraft, try changing it to two groups with single aircraft. A "Pilot01" group and a "Pilot02" group. I have a suspicion, MIST is treating groups as units (?).

If they are in the same group it is unfortunately a limitation of DCS at present. A while back you could only have one client aircraft per group, but they changed it so each unit could be a client. However they haven't in turn added a "Message to Unit" functionality. The smallest entity we can send a message to is the group. If they aren't in the same group, then there could be a bug in my code.

[Darkfury]

Thanks a ton Grimes. At least I know I am not doing anything wrong. They are all in the same group. Damn that current limitation!

 

I will amend my mission to either separate them, or skip that bit.

 

Thanks doodenkoff for trying to help as well!

[Zarma]

Hi guys.

 

Is there a way in MIST to set an air unit with unlimited fuel or set his fuel back to full ?

 

In my case, it's a reaper acting as JTAC. If I use a respawn script while he is on a scripted orbit, the game crashes.

[Johnny_Rico]

DCS engine only has facilities to read fuel status, sadly you cannot write values

Damn !

MIst units in zone flag function

 

Any help is appreciated, my apologies if this is not the appropriate thread.

I'm trying to accomplish: When Troops dropped via CTLD are in zone, flag is set to true. This works fine with ME units active or late activated however, when "Dropped Group #" is in zone, nothing is returned. Can anyone please advise, I would appreciate it greatly.

 

Thank you.

 

blueZoneUnits = mist.makeUnitTable({'[blue][vehicles]'})

 

trainStation1 =

{

units = blueZoneUnits,

zones = {"9_TrainStation1"},

flag = 901,

zone_type = "sphere",

req_num = 1,

interval = 5,

toggle = false,

unitTableDef = blueZoneUnits,

}

 

mist.flagFunc.units_in_zones(trainStation1)

[ESAc_matador]

Most probably because the list of units with makeunittable only takes the initial units. Dropped, spawned, cloned units, can have the same name, but different ID.

 

Unless you redo the list after dropping units it won't work.

 

You can make a loop repeating the script every minute to ensure it takes into account all units

[Vatikus]

mist.groupToRandomZone and others in this group of functions do not have parameter to set if AI should use roads or not.

Wiki page does not reflect what is in code! Code should be fixed asap ...

[Scatoogle]

Hopefully someone smarter than me can tell me why I am getting this error?

 

 

Here is the script:

 

local grpTemplate = {

units = Group.getByName("Insurgent BTR-80"):getUnits(),

country = 17,

category = "GROUND_UNIT",

groupName = nil,

groupId = nil,

clone = true,

route = nil

}

 

mist.dynAdd(grpTemplate)

[Grimes]

Group.getByName("Insurgent BTR-80"):getUnits() returns a group of unit objects, its not in the same format that mist.dynAdd() is expecting for the units table.

 

You can just grab the data directly from mist.DBs, for example:

units = mist.DBs.groupsByName["Insurgent BTR-80"].units

More specifically you can just add the clone value to a table that is grabbed from the DB itself, for example:

local grpTemplate = mist.getGroupData("Insurgent BTR-80")
grpTemplate.clone = true
mist.dynAdd(grpTemplate)

 

 

 

mist.groupToRandomZone and others in this group of functions do not have parameter to set if AI should use roads or not.

Wiki page does not reflect what is in code! Code should be fixed asap ...

 

It automatically forces roads if the group is more than 1.3x the radius of the zone away from the center. If you want more control over it just feed the data you want into mist.groupToRandomPoint()

[maverickturner]

I'm having a hard time trying to figure out a simple script with MIST. I'm looking to simply set a Flag value if a player destroys another player

(RED team killed member of BLUE), set flag 7001,1

 

Can anyone help me with this? I've been searching most of the day and can't seem to figure it out in my rookie stages. Apologies if this isn't the appropriate thread.

You have to use an event handler. A really basic example could be something like...

 

local lastHit = {}
local function score(event)
   if event.id ==  world.event.S_EVENT_HIT then
       if event.target and mist.DBs.humansByName[unit.getName(event.target)] then
           if event.initiator and mist.DBs.humansByName[unit.getName(event.initiator)] then
               lastHit[unit.getName(event.target)] = Unit.getName(event.initiator)
           end
       end
   elseif  event.id ==  world.event.S_EVENT_DEAD then
       if event.initiator and mist.DBs.humansByName[unit.getName(event.initiator)] and lastHit[unit.getName(event.initiator)] then 
           if mist.DBs.humansByName[unit.getName(event.initiator)].coalition == 'red' then
               trigger.action.setUserFlag(7001, 1)
           else
           
           end
       end
   end
end
mist.addEventHandler(score)

Grimes, this is absolutely perfect. Just what I was looking for. I'll test it out when I get home today. Thanks for the help!

To use this code in conjunction with say CTLD, would I identify the medical helos like this:

 

if event.target == ctld.transportPilotNames and mist.DBs.humansByName...

 

I'm getting the overall idea but missing something due to my lack of experience with .lua.
