How Would I Make an Inventory System with Tables?
When making RPG games, most if not all of them include an inventory system that works like this:
Let's say there are 3 items. each labeled Item1,Item2 and Item3.
Now, if I were to remove Item2, then Item3 would slide into the position of Item2 and Item2 would be equipped.
By observing other scripters and developers, I found that I would have to use a table to conduct such things. I have no experience in making tables, all I do know is that a table contains values that can be summoned with TableName.value. I also do know that you have to summon a table with curly brackets ({,}).
Sorry if it's hard to read, but I'm really desperate. Can anyone show me examples of a table and how I would use it to create an inventory system?

Hey Sensei_Developer
This is a really interesting question you've asked.
What I would do is, have a server script;
1 | local data = {} -- create a table, and name it 'data' |
2 |
3 | game.Players.PlayerAdded:Connect(function() -- player added event. |
4 | data[plr.Name] = {"Starting Weapon", "Another Weapon"} -- create a new table inside of the 'data' table, name it after the player's name, and give them a weapon. |
5 | print(data[plr.Name][1]) -- Would print > 'Starting Weapon' |
6 | print(data[plr.Name][2]) -- Would print > 'Another Weapon' |
7 | end) |
So with this code, there are multiple things you can do, I'll list a few!
Use Datastore service, to load and save. (Check for data else give them starting weapon) Fire the client, to update their inventory. Using remove events.
To add a weapon:
1 | table.insert(data[plr.Name], #data[plr.Name]+1, "Hello") -- will insert hello, to position two in the players table. |
2 | print(data[plr.Name][3]) -- Would print > 'Hello' |
To remove a weapon:
1 | function getIndex(tbl, weaponName) -- new function named, getIndex. |
2 | for i,v in pairs(tbl) do -- for loop, to iterate though the table |
3 | if v == weaponName then -- if the weaponName = the current iteration value |
4 | return i -- return the index of 'weaponName' |
5 | end |
6 | end |
7 | end |
8 |
9 | table.remove(data[plr.Name], getIndex(data[plr.Name], "Starting Weapon")) -- Would remove the starting Weapon. |
I hope this has helped you a little.
I am fairly new to tables myself, but I hope this helped
