MIssion Scripting Tools (Mist)- enhancing mission scripting Lua

Respawn doesn't work anymore. Any update? Thks!

MIST doesn't work at all for me, no random flights or anything is spawned

Well it works here, latest OB (as of yesterday).

We've got an intensively dynamic training mission, and everything still works as advertised.

Teleport does not work... anyone can replicate?

Actually it does work with version 4.3.73 but NOT with 4.3.74...

Don't know if this has been reported but mist.flagFunc.mapobjs_dead_polygon is not working in the current build of DCS, either OB or stable. It was just working before the last DCS update. We've tested and used this frequently but now it's broken. I've been using the development branch of MIST, 4-4-78. Any thoughts on what might be causing the problem and how to make it work again?

Flew a mission last night with many folks that used to work and now doesn't. Going to investigate, but it heavily uses get.unit. mist.flagFunc.units_in_zones and mist.flagFunc.units_in_polygon...that sort of thing.

A while back get.group was broken and so we were forced to use get.unit...maybe something similar is happening here. Not sure how mist.flagFunc.mapobjs_dead_polygon works, but I'm guessing ED changed something in the base scripting engine.

I also would love any insight one of the smart people on here might have to share.

Which map and what type of object is it trying to detect?

For me, Black Sea and aircraft. Both by name and by using the built in filters... blue, airplane, helicopter, etc.

As far as I know CTLD was still working fine, so IDK. I'm going to fly it a bit tonight as check out the logs and such and see if I can provide more info.

Ok Grimes, reloading the scripts into the mission fixed most of it, but I was still getting some weirdness with the flags being triggered like an airplane busted a zone, but no airplane was active or anywhere near said zone. And it was triggering after a set amount of time...which also didn't make sense because the mist function starts almost at mission start.

TLDR, I have two zones defined by the waypoints of 2 helos, both late activated, that butt up against each other in some areas. The helos are of opposing coaltions... I changed them to the same coalition and problem solved.

It seems to me that mist.flagFunc.units_in_polygon was detecting when, given it's flight path and speed, the opposing coalition late activated helo WOULD have crossed into that polygon had it been active.

Anyway, original question of getUnit vs getGroup seems to have been faulty.

I hope that's a datapoint that's useful somehow. Thanks ~

Which map and what type of object is it trying to detect?

Anything, buildings, bridges, runways. I can do a test again if you want and send you the file. Everything was working fine up till the last patch. Are you still working on a new version of MIST?

File would help. I did try it on a tester version so it is always possible that it works on that but not the current patch. But I tested on a bridge on Caucuses.

Please keep the file as simple as possible.

I tested this back 3 or 4 weeks ago and I was successfully getting the runway as being destroyed. It is working for buildings in all the different versions so I'm not sure why it's not working in our dynamic mission. I'll have to look it over again. But I tried adding some static object mines and I'm guessing that MIST won't detect objects that have been added in. Any thoughts would be appreciated.

There are two factors at play here.

1. Location of the zone relative to the position of the "airbase." In short the airbase object is not where you think it is. It is just a single point in 3d space that for some reason or another on Cacuases is at one end of the runway and off to the side. So it is possible for the zone covering the runway to not have the center of the runway within it.

2. It is dependent on the death event occurring. I switched the aircraft to the Su-25T because when I test stuff like this I am a lazy keyboard pilot and don't plug my joystick in. As such I used proper runway destroying bombs and got the message to appear fairly easily.

That functionality only checks for map objects, or in other words scenery objects. Which are objects that are placed on the map by default. It ignores anything you place in the editor. It is actually kind of a fluke that it detects the airbase because it returns enough of the same data as a world object to classify it as such.

OK, thanks! We'll play around with it some more.

Hi Montrose

This is the error:

'RedAir1'.... (look at the end, you miss this sign ')

But anyway, I'd try this script to work, and I can't, if you have succeed tell me how please.

having trouble trying to respawn when a group is dead - I am very very very new to this

 

mist.flagFunc.group_dead {

units='RedAir1,flag=100, toggle=true,}

 

I get [strin "mist.flagFunc.group_dead {…"]:2:unfinished string near'<eof>

 

 

I checked to make sure RedAir1 is alive (its set to uncontrolled and present)

 

 

I know this will be something silly I am missing but ….. Any help would be appreciated

mist.flagFunc.units_in_polygon help

Hello all!

Checking the examples on the hoggit wiki, it would seem the following code should fire flag 300 to true work whenever a BLUE aircraft enters the zone...

do
mist.flagFunc.units_in_polygon {
units = {'[blue][plane]'}, --unit names
zone = mist.getGroupPoints('poly'),
flag = 300,
}
end

However, it seems to be making the flag true at almost random times..... Anywhere from 10 seconds after the script is loaded, to a few minutes. The problem is, there are no BLUE aircraft anywhere near the Polygon I've defined (unit name is poly).

Any suggestions?

Sedlo, I was having weird issues with one of my missions a little while ago and the solution might apply here. If your units waypoints that define the polygons cross, even if they are late activated and never would actually be there, the flag might get tripped.

I had two borders that were defined by late activated helos, and it seemed that the flag was getting tripped at the time that the helo's would have crossed paths had they been activated and flying at their assigned speeds. I moved the waypoints around to make sure they didn't cross and the problem was solved.

I don't know if this applies in your case because it is random for you but it might be worth checking out especially if you have randomly activated units that might cross that boundary.

Good luck ~

Interesting! Thanks for the info! I've got two units on the map which define zones, but they are not touching each other at all.. It's strange!

\I deleted one of those other poly groups, then changed the script so that {'[blue][plane]'} got captilized {'[bLUE][PLANE]'}. It's working now!

Thanks to johnv2pt0!

Yeah that was a lovely bug that was fixed and reappeared less than a year later. Think its actually getting fixed in the next patch. Anyway I always use ground units to define polygons and set their probability of appearing to 0%. Mist just needs the path to be in the mission file to find it.

Hi,

I'm building a mission with scrypt but I can not make it all work ..

I want try a mark spot. I copy past the cod from her: https://forums.eagle.ru/showthread.php?t=193232 For apply to my tanker but it did not work.

Tanker name group is KC135mprs. What wrong?

Thank

Plane = Group.getByName( "KC135mprs" )

if Plane and Plane:isExist() then

local Vec3 = Plane:getUnit(1):getPosition().p

local GroupID = Plane:getID()

trigger.action.markToCoalition( 2, "Plane Marking", Vec3, GroupID )

end

I am trying to have AI aircraft spawn in a random location in a zone for ACM. I have them activated via a radio message, then immediately run the mist.teleportInZone, which does randomize their location - but it is like it creates a new aircraft. It has a different skin and doesn't follow it's task/waypoint - just heads for the closest airfield and lands. I even flew right up behind it and shot it with no reaction.

I have even tried Triggered Action after a 10 sec wait to change waypoint/engage Player aircraft etc but it does not respond at all.

Any suggestions?

It does create a new aircraft, just it shares as many parameters of the old one as possible and erases the old one. Its not actually a teleport, it just mimics it. Make sure it has the 2nd value for the command since that defines whether or not it keeps the same task.

mist.teleportInZone('group', true)

Is their a way to set a timer on when a group respawns. I have a FreeFlight missions build and trying to put a delay spawn on to the drones that i have flying around. Here is a copy of the script that i use to respawn them

for k, v in pairs(droneACDB) do

if not Group.getByName(v['group']) then

local msg = {}

msg.text = "Respawning" .. v['name'] .. "Drone Group."

msg.displayTime = 30

msg.msgFor = {coa = {'all'}}

mist.message.add(msg)

mist.respawnGroup(v['group'], true)

local con = Group.getByName(v['group']):getController()

con:setOption(AI.Option.Air.id.ROE, AI.Option.Air.val.ROE.WEAPON_HOLD)

con:setOption(AI.Option.Air.id.RADAR_USING, AI.Option.Air.val.RADAR_USING.NEVER)

con:setOption(AI.Option.Air.id.SILENCE, true)

con:setOption(AI.Option.Air.id.REACTION_ON_THREAT, AI.Option.Air.val.REACTION_ON_THREAT.EVADE_FIRE)

end
