Builder bots are the only mobile unit. They construct buildings, heal friendly entities on a chosen tile, and can make a weak attack against the building under them.

Movement
Builder bots can move to an adjacent tile (including diagonals) if their move cooldown is 0. Moving increases the cooldown by 1.
Builder bots can only walk on:
- Conveyors, splitters, armoured conveyors, and bridges (any direction, either team)
- Roads (either team)
- The allied core
These are called walkable tiles. The direction of the building does not matter, and neither does the presence of resources on the tile. # Move towards a target
direction = c.get_position().direction_to(target)
if c.can_move(direction):
c.move(direction)
Actions
When action cooldown is 0, a builder bot can perform one of:
Build
Build any building or turret on a tile within action radius that doesn’t
already have a building.
If a tile already contains a builder bot, only walkable buildings
(conveyors and roads) can be built on that tile.
Heal
Spend 1 Ti to heal 4 HP to all friendly entities on a tile within action radius. If a friendly builder bot and a friendly building share the chosen tile, both are healed. The action fails if nothing on that tile would gain HP.
if c.can_heal(target_pos):
c.heal(target_pos)
Attack
Spend 2 Ti to deal 2 damage to the building on the tile the builder bot is standing on. This reuses the standard can_fire() / fire() combat API. Armoured conveyors are immune to builder bot attacks.
my_pos = c.get_position()
if c.can_fire(my_pos):
c.fire(my_pos)
Destroy
Destroy any allied building within action radius. This can be done any number of times per round and does not cost action cooldown.
if c.can_destroy(building_pos):
c.destroy(building_pos)
Self-destruct
A builder bot can self-destruct at any time. It does not deal damage.
Markers
Builder bots (like all units) can place one marker per round within action radius, separate from the action cooldown.
