Question

Well, I know how to create a table/metatable with their initial values, but I don’t know how to insert or remove an element after its creation. How can I do this using the best practice in Lua Script? Is there any kind of standart function to do this?

Answer 1

Here’s just about every way of inserting and removing from Lua tables; firstly, for array-style tables:

local t = { 1, 2, 3 }

-- add an item at the end of the table
table.insert(t, "four")
t[#t+1] = 5  -- this is faster

-- insert an item at position two, moving subsequent entries up
table.insert(t, 2, "one and a half")

-- replace the item at position two
t[2] = "two"

-- remove the item at position two, moving subsequent entries down
table.remove(t, 2)

And for hash-style tables:

local t = { a = 1, b = 2, c = 3 }

-- add an item to the table
t["d"] = 4
t.e = 5

-- remove an item from the table
t.e = nil
