Prototype/Unit

Template:Prototype parent Entity that attacks players.

Usage in base

• biters/spitters

Mandatory properties

This prototype inherits all the properties from Prototype/EntityWithOwner.

Template:Prototype property Requires animation in attack_parameters. Requires ammo_type in attack_parameters.

Template:Prototype property Movement speed of the unit in the world, in tiles per tick. Must be equal to or greater than 0.

Template:Prototype property How fast the run_animation frames are advanced. The animations are advanced animation_speed frames per distance_per_frame that the unit moves.

frames_advanced = (distance_moved ÷ distance_per_frame) * animation_speed

Template:Prototype property The amount of pollution that has to be absorbed by the unit's spawner before the unit will leave the spawner and attack the source of the pollution.

Template:Prototype property Max is 100.

Note: Setting to 50 or above can lead to undocumented behavior of individual units creating groups on their own when attacking or being attacked.

Optional properties

Template:Prototype property The sound file to play when entity dies.

Template:Prototype property If the unit is immune to movement by belts.

Template:Prototype property Table with the following mandatory properties:

• warmup_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• warmup2_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• attacking_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• cooldown_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• prepared_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• back_to_walk_frame_sequence - Array of uint16 - Indices of frames from the attack parameter animation.
• warmup_animation_speed - float
• attacking_animation_speed - float
• cooldown_animation_speed - float
• prepared_animation_speed - float
• back_to_walk_animation_speed - float

Template:Prototype property Ignored if walking_sounds is not defined.

Mandatory values

Units have additional requirements for the properties inherited from Prototype/EntityWithOwner:

• Prototype/EntityWithOwner#is_military_target must be true.
• Prototype/EntityWithOwner#allow_run_time_change_of_is_military_target must be false.
