View source for Ruleset Reference (OpenXcom)

A reference of all the customizable values of everything in a [[Rulesets (OpenXcom)|ruleset]] for the current stable version (1.0) of OpenXcom. For the current nightly versions (with the advanced features currently in development) check [[Ruleset Reference Nightly (OpenXcom)|Ruleset Reference Nightly]].

Some guidelines:
* If a value is omitted from the ruleset, the default is used. You cannot omit ''required'' values.
* Text strings (eg. names) are represented by string IDs from the [[Translations (OpenXcom)|language files]]
* Numerical IDs (used for sprites, sounds, etc.) start at 0, not 1.
* Boolean (yes/no) values are represented by true/false.
* World coordinates are represented in degrees (see [[WORLD.DAT]]).
* Money amounts (prices, costs, etc.) are represented in dollars.
* All paths are '''case sensitive'''! If your ruleset uses external files, make sure that they named properly as described in ruleset.

Items are ordered as they come in the ruleset. To override this, you can specify a ''listOrder''. You can find the default listOrders in [[Ruleset List Order (OpenXcom)|Ruleset List Order]].

| 1
|-
| '''type'''

* 0 - Default
* 1 - Landing Zone (for placing X-COM / alien craft)
* 2 - E-W Road (for city maps)

*'''frequency''' defines the odds of the map appearing on the map
** The value assigned (default: 1) is used in ''x/n'', which defines the probability of being chosen.
** ''x'' is the integer defined for the map block's frequency and ''n'' is the combined total of probabilities for all the map types combined.
** This property can only be used in type 0 map blocks.
*'''maxCount''' is the maximum number of times it can be used.
** The value assigned is also used in ''x/n'' to determine the probability of being chosen. 
** Each use reduces ''x'' by -1, with the caveat that being used as a Landing Zone type will not reduce the x value since it could result in no available Landing Zones.
** This property can only be used in type 0 map blocks.
* '''hemisphere''' only applies to UFO missions, not Terror ones.
*'''width/length''' defines the size of the map 
** be aware that the mapview "width"-label is the openxcom ruleset length parameter 
** be aware that the mapview "length"-label is the openxcom ruleset width parameter

==== Guidelines/Tips ====
* All maps with an XCOM/Alien craft require at least one type 1 map block. This map block can only contain ground tiles (no walls or objects), otherwise the game will crash or the walls/objects will be removed. 
* All Terror terrains (listed under STR_TERROR_MISSION) require at least 1 map block of '''Types''' 2, 3 and 4 (for a total of 3 maps, which are required to place roads) and the corresponding '''roadTypeOdds''' added to the ruleset. 
* If there isn't any map blocks designed as roads since you want to keep your terrain 'random', this can be circumvented by designating all 10x10 map blocks, excluding the one(s) used for the XCOM craft, as either '''Type''' 2, 3 and 4 and by defining their '''subType''' to 0. The game will then randomly choose between the map blocks for each type used in the roads, making them map more random.

=== Alien Item Levels ===

This is a list of item level probabilities, with a number between 0 and 2 representing an item level from plasma pistols to heavy plasmas, as defined in the deployments, expressing a 10% probability for that item level being used.

0 = first set (plasma pistol/clip)
1 = second set (plasma rifle/clip)
2 = third set (heavy plasma/clip)

For example:
[ 2, 0, 0, 0, 0, 0, 0, 1, 1, 1 ]
would represent a 60% chance for pistols, 30% rifles, and 10% heavy weapons.<br>
Note that the order does not matter, but the length DOES. each line MUST have 10 digits.

The above can be confusing. There are 10 fields; each number represents 10%.<br>
There are six instances of '0'. 6x10% = 60% chance of plasma pistol<br>
There are three instances of '1'. 3x10% = 30% chance of plasma rifle<br>
There is only one instance of '2'. 1x10% = 10% chance of heavy plasma<br>

Each line represents a month after the beginning of the game, and there is no limit to the number defined.<br>
OpenXCom will use the most recently available item level in the event the game goes on forever.
