Strategy: RatedFieldGrowth

Purpose to increase the field levels while keeping a given proportion between resources
When to use when you need some resources less than others
When to avoid when you want to grow your village in the quickest possible way and your resource fields are balanced

The RatedFieldGrowth strategy will try to grow the fields while keeping the given proportion between resources. After a run, the strategy will be called again when the field level has been completed, when the needed resources have become available or after “checkTimeMinutes” has passed since the last check, whatever comes first. It is a good idea not to use a very short “checkTimeMinutes” value otherwise the nanny will hopelessly keep checking the fields while something is still growing or resources aren't available.

From version 2.3.0 there is an optional new parameter at top level sets max level for any field, once reached this field type will no longer be grown but others will so rate difference will not be maintained.

Individual resource types can have different maximums using an optional parameter line to specify individual types.


  • The production rate doesn't have to be an integer, so you could use “0.5” or “1.27”


<strategy class="RatedFieldGrowth" desc="DESCRIPTION" enabled="true" maxLevel="LEVEL"
          runWhile="RUNWHILE_UID" waitFor="WAITFOR_UID" uid="UID">
	<productionRate wood="WOOD_RATE" clay="CLAY_RATE" iron="IRON_RATE"

Attributes and parameters

DESCRIPTION some optional description of your choice
WAITFOR_UID See "Strategies"
RUNWHILE_UID See "Strategies"
UID Unique IDentifier. See "Strategies"
CHECKTIME sleep timeout
RES_PROD the production rate for one of the resource types, strategy will finish when reached
LEVEL the maximum level to grow fields to, when reached the strategy will finish - default 999
RESTYPE one of “clay”/“wood”/“iron”/“crop”
RESLEVEL the maximum level to grow individual resource field to - default LEVEL


<strategy class="RatedFieldGrowth" desc="Half Crop" enabled="true" uid="s9283">
	<productionRate wood="2" clay="2" iron="2" crop="1" 
        <whileProductionBelow clay="1000" />

The example below grows WOOD and CLAY to level 9 but limits iron to 6 and crop to 5 which is the level at which a Grain Mill can be constructed.

       <maxLevel iron="6" crop="5" />
