Hello,

Simple lua game with simple class like so:

creature = class({ name = "MONSTER BADDY!",

stats = { power = 10, agility = 10, endurance = 10, filters = {} },

other_things = ... })

creatureA = creature.new()

creatureB = creature.new()

creatureA.name = "Frank"

creatureB.name = "Zappa"

creatureA.stats.agility = 20

creatureB.stats.power = 12

-- blah blah blah

Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table.

Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic?

Q2: How would you have each instance of creature have it's own stats table (and sub tables)?

PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation.

Thanks a bunch.
