Harvester & Foundry - Cambridge Battlecode

Harvester

Must be placed on an ore deposit. Outputs one stack of the corresponding resource to an adjacent building every 4 rounds. The first output happens immediately on the round the harvester is built. Prioritises outputting in directions used least recently.

Property	Value
HP	30
Base cost	80 Ti
Scaling	10%
Output interval	4 rounds

# Build a harvester on an ore tile
if c.can_build_harvester(ore_pos):
    c.build_harvester(ore_pos)

Harvesters are expensive (80 Ti base, +10% scaling) but they generate resources passively. Build them on ore deposits early to fund your expansion.

Axionite Foundry

Takes one stack each of titanium and raw axionite, then outputs one stack of refined axionite. Accepts input and produces output from any side.

Property	Value
HP	50
Base cost	120 Ti
Scaling	100%

Foundries have the highest scaling contribution at +100% each. Building one adds 100% to your cost multiplier (e.g. 1.0x → 2.0x if it’s your first build, but 1.5x → 2.5x if you’ve already built other things). Plan carefully before committing 120 Ti.

Refining process

Feed titanium (via conveyor) → foundry stores it
Feed raw axionite (via conveyor) → foundry combines them
Foundry outputs one stack of refined axionite to an adjacent accepting building
