Step 83

The value of the currentWeapon variable corresponds to an index in the weapons array. The player starts with a "stick", since currentWeapon starts at 0 and weapons[0] is the "stick" weapon.

In the buyWeapon function, use compound assignment to add 1 to currentWeapon - the user is buying the next weapon in the weapons array.

where are you adding 1 to curretnWeapon?

5

i added it in my ‘if’ function but i think i did it wrong.

6

I don’t see it, that’s why I am asking. There isn’t an addition of 1 to currentWeapon. Do you remember how you add a number to a number? You already did something similar a few lines above
