In Lua, you can declare a class using the following syntax:
-- Create a new class
ClassName = {}
-- Create a constructor function for the class
function ClassName:new()
local object = {}
setmetatable(object, self)
self.__index = self
return object
end
-- Define methods for the class
function ClassName:sayHello()
print("Hello from the class!")
end
This creates an empty class called
ClassName. The new function is the constructor for the class which returns a new object instance of the class. The __index field ensures that the object inherits methods defined in the class table.
Here's an example of how you can create an instance of the class and call its method:
-- Create an object instance
local myObject = ClassName:new()
-- Call a method on the object instance
myObject:sayHello()
This will output:
Hello from the class!
