I am new to Lua, so while creating and accessing a class in a lua code. I am getting the following error
attempt to index global 'BankAccount' (a function value)
The code block is below for reference.
-- classes in lua
-- bank account is a table
BankAccount = {
account_number = 0,
holder_name = "",
balance = 0.0
}
function BankAccount:deposit(amount)
self.balance = self.balance + amount
end
function BankAccount(amount)
self.balance = self.balance - amount
end
function BankAccount:new(t)
t = t or {}
setmetatable(t,self)
self.__index= self
return t
end
-- instantiate an object of the class BankAccount
johns_account = BankAccount:new({
account_number = 12345678,
holder_name = "John",
balance = 0.0
})
print(johns_account.account_number)
Could anyone explain what error am I making or something else I am missing?
The line function BankAccount(amount)
redefines BankAccount
to be a function.
The line should be function BankAccount:withdraw(amount)
.
