Usage in base

• biters/spitters

Mandatory properties

This prototype inherits all the properties from Prototype/EntityWithOwner.

run_animation

Type: RotatedAnimation

attack_parameters

Type: AttackParameters
Requires animation in attack_parameters. Requires ammo_type in attack_parameters.

movement_speed

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

distance_per_frame

Type: float
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

pollution_to_join_attack

Type: float
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.

distraction_cooldown

Type: uint32

vision_distance

Type: double
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

rotation_speed

Type: float
Default: 0.025

dying_sound

Type: Sound
The sound file to play when entity dies.

min_pursue_time

Type: uint32
Default: 10 * 60

has_belt_immunity

Type: bool
Default: false
If the unit is immune to movement by belts.

spawning_time_modifier

Type: double
Default: 1

max_pursue_distance

Type: double
Default: 50

radar_range

Type: uint32
Default: 0

ai_settings

Type: UnitAISettings

move_while_shooting

Type: bool
Default: false

can_open_gates

Type: bool
Default: false

affected_by_tiles

Type: bool
Default: false

render_layer

Type: RenderLayer
Default: "object"

light

Type: LightDefinition

walking_sound

Type: Sound

alternative_attacking_frame_sequence

Type: table
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

running_sound_animation_positions

Type: table (array) of float
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.
