I'm having problems getting the desired escorts for a Boa 2...

For simple escorts you can use

escort_role (the role of the ship) or
escort_ship (the key of the ship).

Combining it with escorts and a number might be useful.

escort_roles offers you a variable number of escorts, you can assign only 1 ship (role) with min and max so that in more dangerous systems more escorts will be assigned.

Neither
escort_role (the role of the ship) nor
escort_ship (the key of the ship)
...seem to work.

Where there is supposed to be 1 escort ship-type, I'm seeing Geckos, Mambas, Sidewinders, Cobra 1's and 3's, etc!

I am using a separate line of:
escorts = 4;
...To define how many escorts to have.

The ships I'm trying to make escorts exist, as I can spawn them separately using this line:

Code: Select all

system.addGroup("navy-asp", 4, [0,0,0], 30E3);

escort_roles = 
(
    { role = "navy-asp"; min = -2; max = 4; }
);

I've updated the wiki a bit to hopefully explain things a bit more. It's a bit tricky: as you say earlier, I find it easy to understand, but I'm a programmer. It's hard to know where exactly to add descriptions, without writing an OXP for every function! (Although, perhaps, in fairness, an OXP for every function is what is needed for non-programmers to get their heads around it).

Strange, I will run some tests tomorrow. However, please try this one:

Code: Select all

escort_roles = 
(
    { role = "navy-asp"; min = -2; max = 4; }
);

You should get between 2 and 4 escorts of your desired role.

EDIT: Do you use a core-Boa2 ? If you reference to this ship you have escorts already defined, means you need to neutralize or overwrite them.

"navy-boa2" =
{
like_ship = "boa-mk2";
accuracy = 10;
aft_weapon_type = "WEAPON_MILITARY_LASER";
forward_weapon_type = "WEAPON_MILITARY_LASER";
escorts = 4;
// "escort_role" = "navy-asp";
"escort_ship" = "navy-asp";
roles = "navy-frigate(99) navy-boa2";
};

So it's "inheriting" boa-mk2's escort_roles ...but shouldn't defining escorts override that?

"escort_roles" = " ";
"escorts" = 4;
"escort_role" = "navy-asp";

Yes, thanks for this. Super helpful to be able to look up examples working templates that are less complicated to modify.

One such I've been looking around to find is a more meaty example than this little snippet for my rustyShips

Code: Select all

this.allowSpawnShip = function(shipKey)
{
  // your code here
  return bool;
}

with language to specify only communist and feudal systems, and no higher than TL 5.. That would be great in the wiki.

this.allowSpawnShip = function(shipKey)
{
   var gov = system.info.government;
   var tech = system.info.techLevel;
   
   switch (shipKey) 
   {
	case "my_ship_01":
	case "my_ship_02":
		
           if((gov === 2 || gov === 4) && tech < 6)
              return true;

         break;
               
         default:
            return false;
            break;   
    }
}

Well, it should, but it doesn't. What you can try is

Code: Select all

"escort_roles" = " ";
"escorts" = 4;
"escort_role" = "navy-asp";

I didn't test it, but I hope it will work.

"escort_roles" = " ";
"escorts" = 4;
"escort_role" = "navy-asp";

"escort_roles" = ();

"escort_roles" = (	{}	);

"escort_roles" = (	{	role = " ";	}	);

"escort_roles" = (	{	role = "navy-asp"; min = 4; max = 4;	}	);

The internal variables are for performance and switch offers you to check multiple ships. Not tested and only typed on the board, so no editor check as well. However, I hope it will work.

...results in absolute weirdness!
4 Navy Asps act as escorts of the Navy Boa 2.

	case "my_ship_01":
	case "my_ship_02":

That line is unnecessary. "context" is passed into the function by the core code when it's checking the equipment item. If you were encountering situations that made that line of code necessary, then something else is happening, and we'd need a bit of context to help out.

I see the possibility of interpreting multiple ships in two senses: One script I can apply to the whole entire shipset, or one script to apply to each core ship that can fork to multiple variants?

    switch (thing_to_switch_on) { // "thing_to_switch_on" is the data element you want to base your switch on
    	case "type 1": // this is the first possible option
    		// ...code specific to type 1
    		break; // you must "break" out of the switch after executing switch code
    	case "type 2": // this is the second possible option 
    		// ...code specific to type 2
    		break;
    	case "type 3": //
    	case "type 4": // we're combining these 2 options
    		// ...code specific to types 3 and 4
    		break;
    	default: // if none of the above were found, this is the "catch any other type" part of the switch
    		// .. code for any other type
    		break; // technically this isn't needed here, but it's useful for ease of understanding and consistency
    }

		case "my_ship_01":
		case "my_ship_02":
		case "my_ship_03":

		case "my_ship_03":
			if (gov == 3 && tech < 4)
				return true;
			break;

However, It is strange that it seems you can't neutralize escort_roles you need to overwrite it. Maybe Admiral phkb knows a solution

	"dock_anaconda" = {
		like_ship = "anaconda";
		escort_roles = (
			{role = ""; min = 16; max = 16;}
		);
		roles = "dockonly";
	};

..Hopefully that helps a bit in understanding the code.
