Binary Deployment Error Message

Alexander_Gu · July 21, 2021, 2:07pm

What is wrong with my code?

# Recruit soldiers and archers to fill out each squadron.
# Each paladin has a decimal number stored in her deployment attribute.
# Convert these to binary and represent them with lines of soldiers and archers next to each paladin.
# Soldiers are 0s, archers are 1s.
# For the bonus goal, add griffins as 2s for trinary number lines next to the warlocks.
# Check the guide for help with binary numbers.
def binary(number):
    string = ""

I get the error hero placeholder needs something to command.

A unit only exists after it is summoned. At the moment, you’re finding nearestSol before summoning the soldier, so of course it can’t be assigned to the newly summoned soldier. The same is true with archers.

One option is to move hero.findNearest(hero.findByType(...))) after the summon command. Another is to instead reference the latest unit by finding the last unit in hero.built.

I tried it, but it doesn’t work. I still get the same error message

Never mind. Here’s my new code

but it still doesn’t work. There is no error message but some troops
get to the wrong spot

Sure, since sol = hero.findByType("soldier") is the list of all soldiers before the one you just summoned.

I changed the code but the same thing happens.
Code:

# Each paladin has a decimal number stored in her deployment attribute.
# Convert these to binary and represent them with lines of soldiers and archers next to each paladin.
# Soldiers are 0s, archers are 1s.
# For the bonus goal, add griffins as 2s for trinary number lines next to the warlocks.
# Check the guide for help with binary numbers.

        string = string +"0"
    if number > 64:
        number = number - 64
        string = string +"1"
    else:
        string = string + "0"

Is the nearest unit the newest one?

Alexander_Gu · July 22, 2021, 2:22pm

I don’t know.(20 chars)

Hydrobolic · July 22, 2021, 7:21pm

Not necessarily, there’s no good reason for them to be correlated. Try referencing the last built unit, which is the last element in hero.built

Alexander_Gu · July 22, 2021, 9:03pm

Thanks for your help. It worked.
