move_east() → x + 1

move_west() → x − 1

move_south() → y + 1

move_north() → y − 1

Each move costs 1 tick and 1 energy.

get_x() / get_y() — current position

Field size: get_max_x() × get_max_y() (10×10 by default)

// Sweep the first row east, then return while (get_x() < get_max_x() - 1) move_east(); while (get_x() > 0) move_west();

EMPTY

Growth only progresses when water_level > 0. Each farming action costs 1 tick + 1 energy. Use get_cell_state() to check which state a cell is in before acting.

while (true) { CellState s = get_cell_state(); if (s == CellState::EMPTY) till(); if (s == CellState::TILLED) plant(CropType::WHEAT); if (s == CellState::READY) harvest(); move_east(); }

🏠 The Base

⚡ Energy recharge

+10 / tick

💧 Tank refill

+8 / tick

📍 Location

(0, 0)

The base tile is at (0, 0). Farming actions (till, plant, water, harvest) are no-ops on the base — they do nothing and waste a tick. Use is_at_base() to check your position.

💡

Return to base when energy or tank runs low. The drone recharges automatically — no function call needed. At max upgrades: 360 energy, 150 tank.

// Go home to recharge, then come back if (get_energy() < 20 || get_tank() < 15) { while (!is_at_base()) { move_west(); move_north(); } wait(20); // charge up }

💧 Water System

Cell drain

−2 / tick

water() gives

+50 water

water() costs

15 tank units

Tank (base)

50 units

Every PLANTED or GROWING cell loses 2 water/tick. When water hits 0, growth pauses — the crop doesn't die, it just stops progressing. Water can go above 50 via water() up to the cell max of 100.

🍄

Mushroom is special — it only grows when water_level > 40. You must water proactively to keep the level high, not reactively when it runs out.

if (get_water_level() < 30 && get_tank() >= 15) water(); // costs 15 tank, gives cell +50 water

💰 Economy

Gold is earned by harvesting crops. Spend it on seeds, water packs, upgrades, and supplier unlocks. You start with 50 gold, 10 wheat seeds and 5 potato seeds.

Crop	Growth	Sell	Seed	g/tick	Unlock
🌾 Wheat	8+12	2 💰	1 💰	0.050	free
🥔 Potato	14+20	6 💰	2 💰	0.118	free

☕ Coffee	40+80	35 💰	20 💰	0.125	1500 💰

buy_seeds(CropType::POTATO, 20); // 2 gold each → costs 40 gold buy_water(1); // +50 tank units, costs 10 gold

🌿 Crop Suppliers

Four crop types are locked by default. Unlock them by purchasing a Supplier in the 🚁 Extra panel. Once unlocked, you can buy seeds and plant that crop. Suppliers persist until you reset the game.

💡

Unlock Corn first — it has the best gold/tick of the non-special crops (0.133). Mushroom needs a smart watering algorithm to beat it (0.150 g/tick when water is maintained). Coffee gives the highest absolute profit: +15 gold per harvest.

⚡ Quick Start Algorithm

A complete working program. Sweeps the field east→west, farms every cell, returns to base when resources are low.

int main() { while (true) { // Recharge if low on energy or tank if (get_energy() < 30 || get_tank() < 30) { while (get_x() > 0) move_west(); while (get_y() > 0) move_north(); wait(15); continue; } // Buy seeds if needed if (get_seeds(CropType::POTATO) < 5) buy_seeds(CropType::POTATO, 10); // Farm the current cell CellState s = get_cell_state(); if (s == CellState::EMPTY) till(); if (s == CellState::TILLED) plant(CropType::POTATO); if (s == CellState::READY) harvest(); if (get_water_level() < 25) water(); // Move: sweep east, then step south and go back west if (get_x() < get_max_x() - 1) { move_east(); continue; } if (get_y() < get_max_y() - 1) move_south(); while (get_x() > 0) move_west(); } }
