So say there’s a table like:
Table = {}
and I added values to the table this way:
Table[value1] = value2
how do I access value2? like this?
if Table[value2] then
-- do stuff
end

This tutorial should help you out.
Values in a table can be assigned in the format of Table[Key] = Value
. To access the value, you must use the key.
In your example, to access value2
, you would write Table[value1]
. Intuitively, you wouldn’t write Table[value2]
to access value2
, as that would assume you already have access to value2
.
For anyone who finds PiL hard to understand, or has formatting issues with it, the Roblox DevHub has an article as well.
If you already have value2 im not sure why you would want to index Table
for value2
?
@sjr04 The reason I want to remove it from the table too is for checks, to make sure the instance or value is no longer a member of the table. Also tables are useful for other things like teams.
Here is a couple of examples on what you can do
local team = {}
table.insert(team, player) -- add a player
local indexInArray = table.find(team, player) -- returns the index if it finds the value passed, otherwise it will return nil
if indexInArray then
local player = team[indexInArray] -- you can get the player again like this
table.remove(team, indexInArray) -- removes a player from the array/team
end
I prefer the example above, but you can also do it like this, and it’s a bit easier to understand
local team = {}
team[player] = true -- add player to team
team[player] = nil -- remove player from team
local isPlayerInTeam = team[player] -- check if a player is in the team
