Stuck for over a year: Library Tactician [Solved]

I need help with the library tactician level, I’ve tried everything I can think of and I’ve been stuck on it for over a year. It always gives me an infinite loop error or one of the soldiers dies.

Here is my code:

# Hushbaum has been ambushed by ogres!
# She is busy healing her soldiers, you should command them to fight!
# The ogres will send more troops if they think they can get to Hushbaum or your archers, so keep them inside the circle!

# Soldiers spread out in a circle and defend.
def commandSoldier(soldier, soldierIndex, numSoldiers):
    angle = Math.PI * 2 * soldierIndex / numSoldiers
    defendPos = {"x": 41, "y": 40}
    defendPos.x += 10 * Math.cos(angle)
    defendPos.y += 10 * Math.sin(angle)
    if ( > 60):
        hero.command(soldier, "defend", defendPos)
        hero.command(soldier, "defend", {'x': 42, 'y': 40})

# Find the strongest target (most health)
# This function returns something! When you call the function, you will get some value back.
def findStrongestTarget():
    mostHealth = 0
    bestTarget = None
    enemies = hero.findEnemies()
    # Figure out which enemy has the most health, and set bestTarget to be that enemy.
    for enemy in enemies:
        if > mostHealth:
            bestTarget = enemy
            mostHealth =
    # Only focus archers' fire if there is a big ogre.
    if bestTarget and > 15:
        return bestTarget
        return None

# If the strongestTarget has more than 15 health, attack that target. Otherwise, attack the nearest target.
def commandArcher(archer):
    nearest = archer.findNearestEnemy()
    if archerTarget:
        hero.command(archer, "attack", archerTarget)
    elif nearest:
        hero.command(archer, "attack", nearest)

archerTarget = None

while True:
    # If archerTarget is defeated or doesn't exist, find a new one.
    if not archerTarget or <= 0:
        # Set archerTarget to be the target that is returned by findStrongestTarget()
        archerTarget = findStrongestTarget()
    friends = hero.findFriends()
    soldiers = hero.findByType("soldier")
    # Create a variable containing your archers.
    archers = hero.findByType("archer")
    for i in range(len(soldiers)):
        soldier = soldiers[i]
        commandSoldier(soldier, i, len(soldiers));
    # use commandArcher() to command your archers
    for i in range(len(soldiers)):
        archer = archers[i]

Finally! I tried on a much faster computer and it worked!!!


Now I’M stuck… Every time, the SAME soldier is taken out…

Hi Oliver_Davidson,

Can you post your code?

I see the problem. You have to define it like enemy you define it like this enemy = hero.findNearestEnemy(). Do you understand more or less?

My computer has decided to be slow today, but a small change and it worked.

I mostly was stuck for so long because I was inactive.
