Improved loot spawner for v1.0.3

[speedweasel 276]

Improved loot spawner for Exile v1.0.3.  Makes the size of loot spawns less predictable and occasionally spawns a large crate full of gear.  Fully configurable.

Instructions:

1. Overwrite the CfgExileLootSettings class in your mission config.cpp file with the code below.  Just overwrite the class - including the class name and the opening and closing braces {} - Do not overwrite the whole config.cpp file.  

class CfgExileLootSettings
{
	/**
	 * Lifetime of loot in minutes. Synchronize this with
	 * the garbage collector settings of your server
	 * CfgSettings!
	 */
	lifeTime = 30;

	/**
	 * Interval in seconds when the client searches for
	 * new buildings to spawn loot in
	 */
	spawnInterval = 12;

	/**
	 * This is a percentage value to determine how many loot
	 * positions should contain loot when the system spawns loot.
	 *
	 * If a building has 20 positions defined, Exile will 
	 * spawn loot in 10 random positions of them.
	 * 
	 * This means smaller buildings spawn less loot and larger
	 * ones spawn more loot.
	 *
	 * You can also cap it at a maximum value. See below.
	 */
	maximumPositionCoverage = 30;

 	/**
 	 * Limit the number of loot positions per building. If the 
 	 * above percentage value exceeds this value, it will be capped.
 	 *
 	 * Example: Coverage is 50%. Building has 60 loot positions defined.
 	 * This results in 30 loot positions and that is too much. So we
 	 * cap this at 10
 	 */
	maximumNumberOfLootSpotsPerBuilding = 3;

	/**
	 * Exile spawns a random number of items per loot spot. This 
	 * is the upper cap for that. So 3 means it will never spawn more than 3 items in one spot.
	 */
	maximumNumberOfItemsPerLootSpot = 7;
	
	/**
	 * This is the mid range for the number of loot items per spot. Exile is most likely to spawn this number of items. https://community.bistudio.com/wiki/random
	 */
	midNumberOfItemsPerLootSpot = 3;
	
	/**
	 * This is the minimum number of loot items per spot.
	 */
	minimumNumberOfItemsPerLootSpot = 1;
	
	/**
	 * This is the chance (as a percentage) of spawning a crate full of items.
	 */
	percentageChanceToSpawnCrate = 1; // 2 = 2% chance to spawn a crate.  Keep it low.
	
	/**
	 * The number of items to spawn in a crate.
	 */
	numberOfItemsPerCrate = 50;
		

	/**
	 * Radius in meter to spawn loot AROUND each player.
	 * Do NOT touch this value if you dont know what you do.
	 * The higher the number, the higher the drop rates, the
	 * easier your server will lag.
	 *
	 * 50m  = Minimum
	 * 200m = Maximum
	 */
	spawnRadius = 60;

	/**
	 * Defines the radius around trader cities where the system should
	 * not spawn loot. Set this to 0 if you want to have loot spawning
	 * in trader citites, ugh.
	 */
	minimumDistanceToTraderZones = 500;

	/**
	 * Defines the radius around territories where no loot spawns.
	 * This does not regard the actual size of a territory. So do not
	 * set this to a lower value than the maximum radius of a territory,
	 * which is 150m by default.
	 */
	minimumDistanceToTerritories = 150;
};

2. Tune the settings in CfgExileLootSettings to your liking.

3. Overwrite the ExileServer_system_lootManager_spawnLootInBuilding function with the code below, using the regular Exile CustomCode overwrite method.

Hey this is really cool. Tested it out and it works well. It can be annoying when a box spawns in front of a door, so just make sure to add the crate to R3F so players can move or load them. Thanks a bunch man! :]

[Super Jerome 370]

@speedweasel Impressive!

[gfourth 39]

Very cool! Can the loot crate chance be set to a decimal like 0.1? To make it REALLY rare...

Sure.  Any number between 0 and 100 should work.  Be aware that 0.1 would mean an average of 1 crate in 1000 loot spawns.  That's pretty rare.  Many players will never find a crate.

[[RG] Salutesh 261]

Lol this is like my container loot system but without the configs and the interaction option.

Nice work.

Yeah, quite an impressive change @speedweasel, I'll have to have a tinker with this..........

[Darksoul47 1]

I did exactly as described above, and got this

ErrorMessage: File mpmissions\__cur_mp.Altis\config.cpp, line 3155: Config: /CfgExileCustomCode.private: '"' encountered instead of ']'

just as the error says, somewhere around line 3155 in the config.cpp file in your mpmission folder, it encountered " instead of ]. simple typo fix. since you didnt post the line in that file i cant tell you exactly what the error is, so youll have to go off of what the error says.

Here is line 3150 to 3160

	class Exile_Car_Van_Guerilla07 						{ quality = 2; price = 12000; };

	class Exile_Car_Van_Box_Guerilla01 					{ quality = 3; price = 17000; };

After commenting out the loot spawner code I used from here, it resolved the issue, but the code starts at line 3238 to 3369, inside ExileCustomCode

somewhere in this code is the typo. Appreciate any help.
