Query:components

Returns all components that are currently contributing to a successful match for this query.

This method is mostly useful when working with queries that match against a single component class. For queries working with multiple component classes, it is often more convenient to call entities.

Usage

query:components()

Returns

Name	Type	Description
components	table	A table where every key is a Component.

Examples

local Regen = Class("Regen", crystal.Component);
local RegenSystem = Class("RegenSystem", crystal.System);

RegenSystem.init = function(self)
  self.query = self:add_query({ "Regen" });
end

RegenSystem.frame = function(self)
  for regen in pairs(self.query:components()) do
    -- Regeneration logic goes here
  end
end
