Lua aray problem [closed]

Question

I'm working on a game but Im havin a bit of a problem. The problem is for example if i buy 1 ham it charges 55 gold and I get 1 ham but if I want 5 ham I get 5 ham but it only charge 55 gold when it should charge 275 gold.

_state = 0
_count = 0
_index = 0

-- List of items you can buy
items = {}
items[0] = {name = 'ham', id = 456, price = 55}
items[1] = {name = 'fish', id = 201, price = 60}
items[2] = {name = 'mushroom', id = 355, price = 150}
items[3] = {name = 'bread', id = 356, price = 10}

The Function

local function onActionItem(action)

amount = ''
suffix = ''
plural = 'a'

if (_count > 1) then
    amount = ' ' .. tostring(_count)
    suffix = 's'
    plural = ''
end

cost = items[_index].price


selfSay('Do you want to buy ' .. plural .. amount .. ' ' .. items[_index].name .. suffix .. ' for ' .. cost .. ' gold?', 1000)
end

Answer 1

You've missed off using _count in the cost

cost = items[_index].price * _count

You also have some tidying up to do with spaces "Do you want to buy5 hams" - two spaces between buy and 5.

For completeness, you'll need extra work on plurals - fish -> fishes, and you want "loaf of bread" (-> loaves of bread) as an item. You may be better off extending the items array to include the plural name rather than assembling it.

Answer 2

Change this line:

cost = items[_index].price

to:

cost = items[_index].price * _count
