Base object definition

Rewardable object is defined similarly to other objects, with key difference being handler. This field must be set to "handler" : "configurable" in order for vcmi to use this mode.

Variables Parameters definition

This property allows defining "variables" that are shared between all rewards and limiters of this object. Variables are randomized only once, so you can use them multiple times for example, to give skill only if hero does not have this skill (e.g. Witch Hut).

Example of creation of a variable named "gainedSkill" of type "secondarySkill":

"variables" : {
	"secondarySkill" : {
		"gainedSkill" : {
			"noneOf" : [
				"leadership",
				"necromancy"
			]
		}
	}
}

Possible variable types:

  • number: can be used in any place that expects a number
  • artifact
  • spell
  • primarySkill
  • secondarySkill

To reference variable in limiter prepend variable name with '@' symbol:

"secondary" : {
    "@gainedSkill" : 1
},

Reset Parameters definition

This property describes how object state should be reset. Objects without this field will never reset its state.

  • Period describes interval between object resets in day. Periods are counted from game start and not from hero visit, so reset duration of 7 will always reset object on new week & duration of 28 will always reset on new month.
  • If visitors is set to true, game will reset list of visitors (heroes and players) on start of new period, allowing revisits of objects with visitMode set to once, hero, or player. Objects with visit mode set to bonus are not affected. In order to allow revisit such objects use appropriate bonus duration (e.g. ONE_DAY or ONE_WEEK) instead.
  • If rewards is set to true, object will re-randomize its provided rewards, similar to such H3 objects as "Fountain of Fortune" or "Windmill"
"resetParameters" : {
    "period" : 7,
    "visitors" : true,
    "rewards" : true
}

Appear Chance definition

This property describes chance for reward to be selected. When object is initialized on map load, game will roll a "dice" - random number in range 0-99, and pick all awards that have appear chance within selected number. Note that object that uses appearChance MUST have continious range for every value in 0-99 range. For example, object with 3 different rewards may want to define them as

  • "min" : 0, "max" : 33
  • "min" : 33, "max" : 66
  • "min" : 66, "max" : 100 In other words, min chance of second reward must be equal to max chance of previous reward
    "appearChance": 
    {
      // (Advanced) rewards with different dice number will get different dice number
      // This allows (for example) choosing two rewards randomly, independent from each other
      // For H3 objects, this is generally not needed and this field can be omitted
      "dice": 1,
  
      // reward will be selected only if random roll value is greater or equal than this
      "min" : 33,
      
      // reward will be selected only if random roll value is lower than this
      "max" : 66
    },

Configurable Properties

Unless stated othervice, all numbers in this section can be replaced with random values, e.g.

"minLevel" : { "min" : 5, "max" : 10 } // select random number between 5-10, including both 5 & 10
"minLevel" : [ 2, 4, 6, 8, 10] // (VCMI 1.2) select random number out of provided list, with equal chance for each

In this case, actual value for minLevel will be picked randomly. Keep in mind, that all randomization is performed on map load and on object reset (if rewards field in resetParameter was set).

Current Day

  • Can only be used as limiter. To pass, current day of week should be equal to this value. 1 = first day of the week, 7 = last day
"dayOfWeek" : 0
  • Can only be used as limiter. To pass, number of days since game started must be at equal or greater than this value
"daysPassed" : 8

Resource

  • Can be used as limiter. To pass, player needs to have specified resources. Note that limiter will NOT take resources.

  • If negative value is used as reward, it will be used as cost and take resources from player
"resources": {
    "crystal" : 6,
    "gold" : -1000,
},
  • Alternative format that allows random selection of a resource type
"resources": [
    {
        "anyOf" : [ "wood", "ore" ],
        "amount" : 10
    },

        "min" : 1,
        "max" : 3
    },
    {
        // Primary skill will be selected randomly, expect those
        "noneOf" : ["knowledge"],
        "amount" : 1
