[Ask A Pro] Tables.....

So I have just discovered the marvels of tables and well. I don't know how to read a table and use it? if that makes sense
so far I have.

sensor = peripheral.wrap("top")
pUnscramble = textutils.serialise(sensor.getPlayers())
write(pUnscramble)

It returns a table with a UUID and a name I want to only use the name and then compare it to a list of names using an if statement?

for k, v = pairs(table) do
  print("key: "..k.." value: "..v)
end

run your table through this and see if you can figure it out

It would help if you showed us the exact output, since different addons return differently formatted tables, and different versions can change this as well.

However, quick overview:

local mytbl = { [1] = "Hello", world = "World!" }
print( mytbl[ 1 ] ) --#prints "Hello"
print( mytbl.world ) --#prints "World!"

In some cases, a table may not explicitly show numerical indexes when serialized, because this is completely valid syntax:

local mytbl = {"a table", "of things"}
print( mytbl[ 1 ] ) --#prints "a table"
print( mytbl[ 2 ] ) --#prints "of things"

Finally, there's a nice trick for comparing something to a list of names, and that is to use a lookup table:

local tPlayerLookup = {
  ["KingofGamesYami"] = true,
  ["Justlan122"] = true,
}

print( "Enter a name: " )
if tPlayerLookup[ read() ] then
  print( "You're in the table!" )
else
  print( "You're not in the table :(/>" )
end
