evgen configuration

Config files are stored in the YAML format

Names for keys should be self-explanatory

Everything that's not a variant must be an integer value

Value constraints

• map_width, map_height: must be between 1 and 50
• starting_animals: must be between 0 and 100
• genome_length: must be between 1 and 100
• min_mutations: must be between 0 and genome_length
• max_mutations: must be between min_mutations and genome_length
• starting_foliage, energy_gain, daily_foliage_growth, starting_energy, min_procreation_energy: must be at least 0
• procreation_energy_loss: must be between 0 and min_procreation_energy

Warning

The above constraints are merely to assure the integrity of the simulation. They do not protect against nonsensical and useless setups, for instance:

• daily_foliage_growth=0: plants will not grow
• energy_gain=0: animals will be unable to gain energy
• procreation_energy_loss=0: children will be born dead
• min_procreation_energy=procreation_energy_loss: procreation may kill the parents
• starting_animals<2, starting_energy=0: simulation will be extremely boring

Available variants

• map_variant: globe, portal
• foliage_variant: equator, toxic
• mutation_variant: random, step
• behaviour_variant: predestined, crazy

Default values

If loading of custom config fails, simulation will use default settings, which can be seen in the Example config file section below.
