THIS WEEK

Make it yours

hero.set_name("Nova")

Choose a name, up to 16 characters.

hero.set_color("purple")

Use blue, red, green, purple, orange, pink, yellow, or white. A hex color like #22aaff works too.

hero.set_hat("crown")

Choose cap, crown, helmet, or none. Run these commands once. Your choices stay saved in this browser, even if you remove the commands. Run them again to change your look.

Hero commands

hero.move("right")

Walk one tile. Use up, down, left, or right. Add a count: hero.move("right", 2) walks two tiles, checking each tile. Collect items separately.

hero.attack("right")

Hit an adjacent enemy once for 3 damage. Add a count: hero.attack("right", 2) attacks twice. Each hit deals 3 damage; surviving guards hit back. Attacking after a guard is defeated gives an error.

hero.collect()

Pick up items on your tile. In Week 5, keys, potions, swords, and gems fill your inventory.

hero.enemy_at("right")

Check for an enemy next to you.

hero.unlock("down")

Open the door next to you. Uses one key of the same color.

hero.activate()

Stand on a switch to open gates of the same color. Keys do not open gates.

code = hero.read()

Read the number sign under your hero and keep its value in a variable. Signs receive new values each run.

hero.enter_code("right", code)

Open an adjacent code door using the variable saved from its matching sign. Keep separate variables for different signs.

hero.heal()

Use a potion to restore 5 health, up to 10.

hero.door_at("right")

Check for a locked door.

hero.can_move("right")

Check if the next tile is clear.

hero.on_coin / hero.on_key
hero.on_potion

Check for something to collect.

hero.health / hero.potions

Check your health or potion count.

Before you start

Inventory command reference · Week 5

Your editor starts empty. The hero is already available; no import is needed. Write your own plan.

hero.collect()

Pick up the items on your tile. Each item joins the end of your inventory. Coins are counted separately.

hero.inventory[index]

Read an item at its current position. The first index is 0. Empty slots have no item.

hero.equip(hero.inventory[index])

Replace index with the position you want. Hold that collected item. Walking carries your whole inventory.

hero.drop()

Leave the held item on your tile. Later items shift left. Collect it again to add it to the end.

print(hero.inventory)
len(hero.inventory)

Inspect the current list or count its items. Up to five items fit. Read hero.inventory again after collecting, using, or dropping an item.

Hold a matching colored key to unlock a door, a sword to attack, or a potion to heal. A used key or potion leaves the list; the sword stays.
