monsterHealth -= weapons[currentWeapon].power * 1 + 0;

The Math object in JavaScript contains static properties and methods for mathematical constants and functions. One of those is Math.random(), which generates a random number from 0 (inclusive) to 1 (exclusive). Another is Math.floor(), which rounds a given number down to the nearest integer.

Using these, you can generate a random number within a range. For example, this generates a random number between 1 and 5: Math.floor(Math.random() * 5) + 1;.

Following this pattern, use the addition operator (+) to add a random number between 1 and the value of xp to your monsterHealth -= weapons[currentWeapon].power.

multiplying by 1 and adding 0 doesn’t change the values at all, you can remove them and the code is the same. You need to make some bigger changes here

5

I’ve tried some big changes, but i still seem stuck, please.

6

what’s your new code now?

7

monsterHealth -= Math.floor(weapons[currentWeapon].power() * 1) + 0;

8

you are still only multiplying by 1 and adding 0. What values are you asked to use in the instructions?

9

1 and the value of “xp”

10

Dear ilenia, are you still with me please?

11

you are not using xp there tho

12

i thought it said the value of xp which i think is 0?

Hi @Physayo

The instructions asked you to add the random number to the following code:

monsterHealth -= weapons[currentWeapon].power;

The last code you posted:

does not have the power of the weapon, and it is not using the random number generator.

It is not doing anything to the weapon power.

You have * 1, this needs to be * xp which is the experience points variable.

You have + 0, this needs to be + 1, this will generate random numbers between 1 and xp, when you code the Math.random() method.

Happy coding

hey @oakth

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.

I think the big hint is this :

  • use the addition operator (+ ) to add a random number.
  • between 1 and the value of xp .
  • this generates a random number
  • between 1 and 5
    -Math.floor(Math.random() * 5) + 1; => so by replace 5 to xp and we got
  • Math.floor(Math.random() * xp) + 1
  • And then we use the addition operator (+ ) to add a random number.
