class_<Derived, bases<Base1, Base2, Base3> >("Derived")

Creating Classes in Lua Using LuaBind

It’s also possible to define classes within your Lua scripts using Luabind.

Here’s how you would go about creating a class similar to

class 'Animal'

function Animal:__init(num_legs, noise_made)

self.NoiseMade = noise_made

self.NumLegs = num_legs

end

function Animal:Speak()

print(self.NoiseMade)

end

function Animal:GetNumLegs()

return self.NumLegs

end
