Script for revealing empty playerside vehicles

[ColonelKernel 4]

I'm trying to write a script for revealing all empty playerside vehicles to the player (MP & SP). This is how I've done it:

0 = [] spawn {
  while {true} do {
     _allEmptyVehs = vehicles select {{alive _x} count crew _x == 0 && (side==playerside)}; //vehicle should be empty (not counting the dead units) and on the player's side
     {
       player reveal _x;
     } foreach _allEmptyVehs;
  sleep 2;
  };
};

The problem is that the unit positions do not update on the map. Can someone please tell me what I'm doing wrong?

Empty vehicles are side civilian I believe (which is why the ai don't shoot at empty vehicles).

 

You can check in their config entry for the default side there:

 

getNumber (configfile >> "cfgvehicles" >> (typeOf _x) >> "side")

 

and it will give you 0 for opfor, 1 for blufor, 2 for independents and 3 for civ.

Then, e.g, why are BLUEFOR vehicles shown as blue on the map? (civilians are purple, right?)

Also can you please check if I've made any errors in the script?

[ColonelKernel 4]

Ok, after checking I've found a few problems:

1. Revealed vehicles disappear (from map) after a unit embarks and then disembarks them, and don't appear again.

2. Empty vehicle markers do not update on the map.

 

How can I keep the position of revealed vehicles updated on the map?

If you get in an empty vehicle, it changes to your side.

 

If you leave and walk off over 100m it reverts to side CIVILIAN.

 

So you can't reliably expect empty vehicles belonging to your faction to be on your side.

 

Check it yourself if you like:

 

onEachFrame{hintSilent format ["%1  %2",side car1,player distance car1]}

Can you please help me with the part I mentioned i.e making units update on the map ? I'm kind of stuck!

I already gave you a way in my first post....

Change this:

 

_allEmptyVehs = vehicles select {{alive _x} count crew _x == 0 && (side player)};

 

To one of these:

 

_allEmptyVehs = vehicles select {{alive _x} count crew _x == 0 && {getNumber (configfile >> "cfgvehicles" >> (typeOf _x) >> "side") == 1}}; // if you are blufor
_allEmptyVehs = vehicles select {{alive _x} count crew _x == 0 && {getNumber (configfile >> "cfgvehicles" >> (typeOf _x) >> "side") == 0}}; // if you  are opfor
_allEmptyVehs = vehicles select {{alive _x} count crew _x == 0 && {getNumber (configfile >> "cfgvehicles" >> (typeOf _x) >> "side") == 2}}; // if you  independent

 

btw: iterating through all the "vehicles" will probably bog down the scheduler if you have a busy mission.

Maybe addVehicle could be used to hold an empty vehicle on a specific side. But I did not test it

Maybe...   I don't fancy checking it either though  ;)

You're right. But I don't have any idea how to do it in a different way. Do you have any suggestions?

What if I limit the distance? Does it improve the performance?

My advice is to run this on clients. This also means it will work for all sides. Second, we know that empty vehicles don't move on their own, so we don't need to constantly update. I believe it is practical to go through all vehicles regularly on the client. There are more advanced ways with event handlers, but just wanted to quickly make something. The only possible problem with doing it client side, is that vehicles that are far away might not get transmitted to clients. Anywhere I made this script, and tested it and it seems to work (not sure how well the _visual commands work, maybe just use ordinary):

if (!hasInterface) exitWith {};

EM_Vehicles = [];

EM_MapDrawCallback = {
    params ["_mapCtrl"];
    // This just draws the data from EM_Vehicles on the map.

Thank you for your reply.

The reason I use the reveal command is because that way I can order my units to get in a vehicle. I did find a way (which is kind of silly!) that solves the update problem. If you have the time to test it, here it is:

0 = [] spawn {
	While {true} do {
    {
    waitUntil {visibleMap};
     _allVehs = _x nearobjects ["allvehicles", 800];
     _allEmptyVehs = _allVehs select {{alive _x} count crew _x == 0};
     {
	 player forgettarget _x;
	 player reveal _x;
     } foreach _allEmptyVehs;
     } foreach units group player;
    sleep 2;
    waitUntil {shownMap};
	};
};

If you could help me iron out the unit position shifting on map (because of using forgettarget) I would greatly appreciate it.

I just did something cool! If I use your script in conjunction with mine and disable friendly icons on the map (in difficulty settings) it actually does what I want!

[Muzzleflash 111]

I see now I misunderstand, and you literally meant reveal. I don't have time to test atm. That script is rather intensive if you have a larger group, since the nearunits check runs for each member of the group. Maybe just increase the radius a tiny bit and just do the search once from the player's position? But I am a bit confused about the use case. You only do this once the player open his map, but he does not have to enter the map to order his units around. If the server is running with higher difficulty, or disabled map icons, I am not even sure it is possible to giver 'getin' orders on the map. Finally, I am not sure what the last line where you waituntil shownMap is for, you already waited for the map to be visible?

Sure go ahead, do what you want with it :)   (yeah my version always draws the vehicles on the map regardless of difficulty settings).

-Actually, I created a ten unit group with 200 vehicles around me and I didn't notice much difference. (except for an initial slowdown because of those 200 vehicles of course!)

-I need it to do the search for all my units because I sometimes I stage my units somewhere far from my position.

-I added the line for it to work once the map is opened because I figured it would improve performance (why should it keep revealing vehicles to me when I still haven't opened the map?)

-To be honest, I don't know why I used that line either ;) I just tried it with plain

waitUntil {visibleMap};

at the start but the script ran only once (i,e the while loop would get stuck at the beginning). Then I tried the waituntil shownMap and it worked! Weird, right?!

Anyway, thanks for your help! I was going crazy with this!

This also fixes the flickering!

     {
	 if (player knowsabout _x != 1) then {player forgettarget _x};
     player reveal [_x, 1];
     } foreach _allEmptyVehs;
     } foreach units group player;
    sleep 2;
    waitUntil {shownMap};
    };
};
