Basics

Prototype type: map-settings

The default map settings. Only 1 instance of this prototype can exist.

Mandatory properties

type

Type: Types/string

Must be "map-settings".

name

Type: Types/string

Name of the map-settings. Must be "map-settings" since only one instances of this prototype can be defined.

enemy_expansion

Type: Types/table

Table with the following mandatory members:

• settler_group_max_size - Types/uint32

unit_group

• max_group_gathering_time - Types/uint32
• max_wait_time_for_late_members - Types/uint32 - After the gathering is finished the group can still wait for late members, but it doesn't accept new ones anymore.

• max_member_speedup_when_behind - Types/double - When a member falls behind the group he can speedup up till this much of his regular speed.
• max_member_slowdown_when_ahead - Types/double - When a member gets ahead of its group, it will slow down to at most this factor of its speed.
• max_group_slowdown_factor - Types/double - When members of a group are behind, the entire group will slow down to at most this factor of its max speed.
• max_group_member_fallback_factor - Types/double - If a member falls behind more than this times the group radius, the group will slow down to max_group_slowdown_factor.
• member_disown_distance - Types/double - If a member falls behind more than this time the group radius, it will be removed from the group.
• tick_tolerance_when_member_arrives - Types/uint32
• max_gathering_unit_groups - Types/uint32 - Maximum number of automatically created unit groups gathering for attack at any time.
• max_unit_group_size - Types/uint32 - Maximum size of an attack unit group. This only affects automatically-created unit groups; manual groups created through the API are unaffected.

path_finder

Type: Types/table

Table with the following mandatory members:

• fwd2bwd_ratio - Types/int32 - Defines whether we prefer forward (>1) or backward (<-1) or symmetrical (1) search.
• goal_pressure_ratio - Types/double - When comparing nodes in open which one to check next, heuristic value is multiplied by this ratio. The higher the number the more is the search directed directly towards the goal.
• max_steps_worked_per_tick - Types/double - When this is exhausted no more requests are allowed, at the moment the first path to exhaust this will be finished (even if it is hundreds of steps).
• use_path_cache - Types/bool
• short_cache_size - Types/uint32 - Number of elements in the cache.
• long_cache_size - Types/uint32
• short_cache_min_cacheable_distance - Types/double - Minimal distance to goal for path to be searched in short path cache.

• cache_accept_path_start_distance_ratio - Types/double - When looking for path from cache make sure it doesn't start too far from requested start in relative distance terms.
• cache_accept_path_end_distance_ratio - Types/double - When looking for path from cache make sure it doesn't end too far from requested end. This is typically higher than accept value for the start because the end target can be moving.
• negative_cache_accept_path_start_distance_ratio - Types/double - Same as cache_accept_path_start_distance_ratio, but used for negative cache queries.
• negative_cache_accept_path_end_distance_ratio - Types/double - Same as cache_accept_path_end_distance_ratio, but used for negative cache queries.
• cache_path_start_distance_rating_multiplier - Types/double - When assigning rating to the best path this * start distances is considered.
• cache_path_end_distance_rating_multiplier - Types/double - When assigning rating to the best path this * end distances is considered. This is typically higher than value for the start to achieve better path end quality.
• stale_enemy_with_same_destination_collision_penalty - Types/double - Somewhere along the path is stuck enemy we need to avoid. This is mainly to handle situations when units have arrived and are attacking the target then units further in the back will use this and run around the target.
• ignore_moving_enemy_collision_distance - Types/double - If there is a moving unit further than this we don't really care.
• enemy_with_different_destination_collision_penalty - Types/double - Enemy is not moving/or is too close and has different destination.

• general_entity_subsequent_collision_penalty - Types/double - Collision penalty for successors of positions that require destroy to reach.
• max_clients_to_accept_any_new_request - Types/uint32 - Up until this amount any client will be served by the path finder (no estimate on the path length).
• max_clients_to_accept_short_new_request - Types/uint32 - From max_clients_to_accept_any_new_request till this one only those that have a short estimate will be served.
• direct_distance_to_consider_short_request - Types/uint32 - This is the "threshold" to decide what is short and what is not.
• short_request_max_steps - Types/uint32 - If a short request takes more than this many steps, it will be rescheduled as a long request.
• short_request_ratio - Types/double - How many steps will be allocated to short requests each tick, as a ratio of all available steps per tick.
• min_steps_to_check_path_find_termination - Types/uint32 - Absolute minimum of steps that will be performed for every path find request no matter what.
• start_to_goal_cost_multiplier_to_terminate_path_find - Types/double - If the current actual cost from start is higher than this times estimate of start to goal then path finding is terminated.

max_failed_behavior_count

Type: Types/uint32

If a behavior fails this many times, the enemy (or enemy group) is destroyed. This solves biters stuck within their own base.
