Properties

count :: uint64 optional

How many units are needed. Must be > 0.

count_formula :: MathExpression optional

Formula that specifies how many units are needed per level of the technology.

If the last characters of the prototype name are -<number>, the level is taken to be the number, e.g. physical-projectile-damage-2 implies a number of 2. This defaults to 1. There does not need to be lower-level technologies for a technology to be detected as having a level, meaning a technology or sequence of upgrade technologies can begin at any number.

For an infinite technology, the level begins at the given suffix (or 1 by default) and gains 1 level upon being researched, or if the max_level is reached, marked as completed. The initial level of a technology can not be greater than its max_level.

l and L are provided as variables in the expression, they represent the current level of the technology.

This formula can also be used at runtime.

Example

count_formula = "2500*(L - 3)"

time :: double

How much time one unit takes to research. In a lab with a crafting speed of 1, it corresponds to the number of seconds.

ingredients :: array[ResearchIngredient]

List of ingredients needed for one unit of research. The items must all be ToolPrototypes.

Example

unit =
{
  count_formula = "2^(L-6)*1000",
  ingredients =
  {
    {"automation-science-pack", 1},
    {"logistic-science-pack", 1},
    {"chemical-science-pack", 1},
    {"production-science-pack", 1},
    {"utility-science-pack", 1},
    {"space-science-pack", 1}
  },
  time = 60
}
