layers Need Help Understanding Layers and Their Functionality

[npmproductions13 14]

Hi there can anyone assist me with using layers to hide a selection of entities using boolean logic or variables for example.

Right now I want to make a ship appear depending on the faction selected in the parameter screen. The wiki describes its many uses for the 3DEN layers like remove,add and set, it also describes the syntax but I'm finding it hard to get working correctly.

Another thing I don't understand is, are the entities "linked" to the value -1 or is it "linked" to the "Enemy Base" String?

There is only one option available to you from inside a runnning mission, being getMissionLayerEntities. The command excepts either a layer ID(NUMBER) or the layers name. The layers available are only those created in the editor, the default side layers are not actually layers.

Both, inside the .sqm all entities belonging to a layer exist in a child class of the layer. The layer class has both a ID(NUMBER) and name(STRING) properties to identify it.

Spoiler

Example of a .sqm with just a single soldier inside a custom layer.

	class Entities
	{
		items=1;
		class Item0	//First item saved
		{
			dataType="Layer";	//Of type layer
			name="Layer 1";		//STRING representing layers name
			class Entities		//class holding entities that exist in this layer
			{
				items=1;
				class Item0	//Child class
				{
					dataType="Group";	//A group
					side="West";
					class Entities		//Groups objects
					{
						items=1;
						class Item0		//First group member
						{
							dataType="Object";
							class PositionInfo
							{
								position[]={4097.647,5.0014391,4145.6558};
							};
							side="West";
							flags=7;
							class Attributes
							{
							};
							id=3;
							type="B_Soldier_F";		//Of type
						};
					};
					class Attributes
					{
					};
					id=0;
				};
			};
			id=4;	//Layer ID
		};
	};

 

 

Untested but something like...

//description.ext
class Params
{
	class ChoosenSide
	{
		title = "Choose Side";
		values[] = {0,1,2};
		texts[] = {"East","West","Independant"};
		default = 1;
	};
};

//initServer.sqf

_sideParam = [ "ChoosenSide", 1 ] call BIS_fnc_getParamValue;

if !( _sideParam isEqualTo 1 ) then {
	{
		_index = _forEachIndex;
		{
			if ( _index isEqualTo 0 ) then {
				deleteVehicle _x;
			}else{
				deleteMarker _x;
			};
		}forEach _x;
	}forEach getMissionLayerEntities "MyLayer";
};

I'm still getting the issue of both sides ships appearing inside each other. I can't get one to delete itself while the other stays etc.. In EDEN iv'e made the layer invisible and want to make 1 and only one appear by script and it seems both layers unhide themselves regardless of the scripts controlling them.

 

I'm even just trying to debug this in the debug console but nothing works like before.

Ok I got the desired results by using the simple code below with some snippets of your code thanks Larrow.

{ 
 deleteVehicle _x; 
} forEach ((getMissionLayerEntities "Munificent") select 0);

Fixed my code, had assignment in _index check, missed a =.

@Larrow

First time I have ever saw you make a typo in your code on these forums. You must be tired, get some sleep!

On a serious note. Good work! As always.
