Need help with Gas Attack JS

Hello. Need help with this lvl. How I shoud count enemy health? What is wrong?

// Peasants are trapped in a valley!
// You only have one poison shell.
// Calculate the required mass of the shell to defeat the ogres.
// The poison mass needs to be equal to the health of the ogres.
// Using too little or too much will be a disaster!

// This function should return the total health of the enemies:
function healthSum(units) {
    // Create a variable and set it to 0 to start the sum.
    var countHit =0;
    var i = 0;
    // Iterate over each enemy in the array and add their health to the sum variable.
    while(i< units.length){
        
 countHit == countHit + units.health;
    i++;
    }
       
    return countHit; // ∆ Change this to return the sum variable!
}

// Use the cannon to defeat the ogres.
var cannon = hero.findNearest(hero.findFriends());

// The cannon can see through the walls.
var enemies = cannon.findEnemies();

// Calculate the sum of the ogres' health.
hero.say("Use " + healthSum(enemies) + " grams.");

countHit == countHit + units.health;

units is an array of units. First you need to get the certain unit units[i] and read its health.

3

something like this?

countHit == countHit + units[i].health

4

Yep. But == is a comparison operator. Use = to assign values.

Thank you!:slight_smile:

def healthSum(units):
# Create a variable and set it to 0 to start the sum.
ogres=hero.findEnemies()
ogreHealth=0
ogreIndex=0
ogre=ogres[ogreIndex]
while ogreIndex<len(ogres):
ogreHealth+=1
ogreIndex+=1
return ogreHealth

Use the cannon to defeat the ogres.

cannon = hero.findNearest(hero.findFriends())

The cannon can see through the walls.

enemies = cannon.findEnemies()

Calculate the sum of the ogres’ health.

hero.say(“Use " + healthSum(enemies) + " grams.”)

My code is not working properly and I do not know why. Can anyone help me?

7

What are doing here?

I think at some point I modified the code without noticing. It is supposed to be ogreHealth+=ogre.health. Even then. It does not work

9

Could you post your new code? And please post it as code (use triple ` to wrap it)

’# Calculate the total health of all the ogres.

def sumHealth(enemies):
# Create a variable and set it to 0 to start the sum.
totalHealth = 0
# Initialize the loop index to 0
loop:
index = 0
while index < len(enemies):
totalHealth = enemies[index].value
index =+ 1
# While index is less than the length of enemies array

    # Add the current enemy's health to totalHealth
    
    # Increment the index.
    

return totalHealth

‘# Use the cannon to defeat the ogres.
cannon = hero.findNearest(hero.findFriends())
’# The cannon can see through the walls.
enemies = cannon.findEnemies()
’# Calculate the sum of the ogres’ health.
ogreSummaryHealth = sumHealth(enemies)
hero.say(“Use " + ogreSummaryHealth + " grams.”)

it says unknown unary operater Uadd

12

I dont think value is the method you want. If you want the health use .health

don’t know what you mean

14

If you want to know the health of an unit you should read .health property. .value is a coin/gem property.

15

just said unknown unary operator: UAdd

16

here’s my code:

Calculate the total health of all the ogres.

def sumHealth(enemies):
# Create a variable and set it to 0 to start the sum.
totalHealth = 0
# Initializhe loop index to 0
index = 0
while index < len(enemies):
totalHealth = enemies[index].health
index += enemies.health
# While index iess than the length of enemies arra
# Add the current enemy’s health to totalHealth

    # Increment the ind
    

return totalHealth

Use the cannon to defeat the ogres.

cannon = hero.findNearest(hero.findFriends())

The cannon can see through the walls.

enemies = cannon.findEnemies()

Calculate the sum of the ogres’ health.

ogreSummaryHealth = sumHealth(enemies)
hero.say(“Use " + ogreSummaryHealth + " grams.”)

I think it’s fine, but it still dosen’t work because all the ogres don’t die and they kill the peasents

Please format your code according to the FAQ

@lazerA.Y Your problem lies here:

while index < len(enemies):
    totalHealth = enemies[index].health   # you should add to totalHealth
    index += enemies.health   # this index should be incremented by 1
