Core The core is each team’s central building. If your core is destroyed, you lose the game. Each team starts with one core.

​
Spawning

The core can spawn one builder bot per round on any of the 9 tiles it occupies. Spawning costs one action cooldown.
Each team can have at most 50 living units total, including the core. That means you can have at most 49 additional living units. Use c.get_unit_count() together with GameConstants.MAX_TEAM_UNITS if you want the exact numbers. c.can_spawn() and any unit-producing c.can_build_*() method already account for the cap.
# Spawn a builder on an empty core tile
pos = c.get_position()  # centre of the 3x3 core
for dx in range(-1, 2):
    for dy in range(-1, 2):
        target = Position(pos.x + dx, pos.y + dy)
        if c.can_spawn(target):
            c.spawn_builder(target)
            break

​
Resource delivery

Resources must be transferred to the core via conveyors to be added to your team’s global resource pool, which is used for building. Raw axionite delivered to the core is destroyed, so refine it first if you want to keep it.

​
Conversion

The core can convert refined axionite from the global resource pool into titanium with c.convert(amount). 1 Ax→4 Ti1 \text{ Ax} \rightarrow 4 \text{ Ti} Converted axionite is removed from the Ax collected stat and added to the Ti collected stat.
