Constructor Detail
Instance Method Detail
Creates new entity in a world context. Basically doesn't cost anything as it just increase entities counter. Entity don't take up space without components.
Creates new Filter.
This call can be skipped:
Instead of world.new_filter.of(Comp1)
you can do world.of(Comp1)
Non-allocating version of #stats
. Yields component names and count of corresponding components
world = init_benchmark_world(1000000)
world.stats do |comp_name, value|
puts "#{comp_name}: #{value}"
end
Returns Hash containing count of components
world = init_benchmark_world(1000000)
puts world.stats # prints {"Comp1" => 500000, "Comp2" => 333334, "Comp3" => 200000, "Comp4" => 142858, "Config" => 1}
