Where should I start if I want to learn how to script Lua on Roblox?

Asked by

I have done scripting for around 6 months. I don't get why I don't get so much better on scripting. Is there a good advice how to be a good scripter and start up?

If there is, Thank you!

Sincerely,

Ducksneedhelp

I've been scripting on Roblox for 2 years and I'm still not that good. :/ DesertusX 435 — 5y

Hi Ducksneedhelp!

I had a similar issue to you.

For beginner scripters, it's best to start with something simple; like changing BrickColors, printing, etc. Work your way up and read/watch tutorials that actually TEACH you how the script works. if you have a script that is having an error, you can always ask this website. This will also help you understand why you made mistakes.

No script can be too complicated if you learn how they work. Here are some functions that will definitely be useful when scripting:

`1`	`print(x)`

Print Function: Will print x in the output. This is mainly used for debugging, where the script is erroring.

Example

`1`	`print("Hello!")`

Output: Hello!

1for i = x, y, z do
2      print(i)
3end

x = number it starts at; y = number it will end at; z = number it goes up/down by. Example

1for i = 0, 10, 2 do
2      print(i)
3end

The value of "i" will start at 0, and it will keep going up by 2 until "i" reaches 10.

Output: 0, 2, 4, 6, 8, 10

`1`	`Instance.new(x, y)`

This function, instance.new() makes a new instance, and becomes a child of y.

Example 1

`1`	`Instance.new("Folder", game.ServerStorage)`

This creates a Folder into the ServerStorage.

Example 2

`1`	`Instance.new("BoolValue", game.ReplicatedStorage)`

This creates a BoolValue (Boolean Value aka True or False statement) into ReplicatedStorage.

Here are simple, intermediate, and complicated scripts:

Simple: Change BrickColor

1local part = script.Parent --Gets the part
2 
3part.BrickColor = BrickColor.new("New Yeller") --Changes the BrickColor of the part to the color "New Yeller"

Intermediate: Changing the Transparency of everything inside the model

1local model = script.Parent --Gets the model
2for i, v in pairs(model:GetChildren()) do --This `for i` function goes through everything inside the model, as it says `model:GetChildren()`. If you don't know what `:GetChildren()` means, it gets everything inside something. In this case, we get everything inside the model
3    if v:IsA("Part") then --If the thing inside the model is a part. We use this to check if the current item inside the model is a part.
4        v.Transparency = 1 --The transparency of the part becomes 1
5    end
6end

Complicated: Datastores

01local ds = game:GetService("DataStoreService") --Gets Service of Datastores
02local ds1 = ds:GetDataStore("CashDataStore") --Gets the Datastore with the name "CashDataStore"
03local ds2 = ds:GetDataStore("WinsDataStore") --Gets the Datastore with the name "WinsDataStore"
04 
05game.Players.PlayerAdded:Connect(function(player) --When a player is added
06    wait() --Makes sure it loads
07    local stats = Instance.new("Folder") --Creates a folder
08    stats.Name = "leaderstats" --The name of the folder is "leaderstats"
09    stats.Parent = player --The parent of the leaderstats is player
10    print("success") --Prints success
11 
12    local Cash = Instance.new("IntValue") --Makes a new IntValue, or Integer Value.
13    Cash.Name = "Cash" --The name of the IntValue is Cash.
14    Cash.Parent = stats --The parent of Cash is stats.
15    Cash.Value = ds1:GetAsync(player.UserId) or 0 --If the player has played the game before, they will have a Cash Value already. But if they don't, they will have 0. (Due to the `or 0` part.)
16    ds1:SetAsync(player.UserId, Cash.Value) --Sets the datastore of the specific player and the value of cash
17    print(Cash.Value) --Prints the cash
18 
19    local Wins = Instance.new("IntValue") --Makes another IntValue
20    Wins.Name = "Wins" --Name is Wins
21    Wins.Parent = stats --parent is stats
22    Wins.Value = ds2:GetAsync(player.UserId) or 0 --Again, gets the wins value of the player, or if they haven't played before, has 0.
23    ds2:SetAsync(player.UserId, Wins.Value) --Sets value of the specific player and the number of wins.
24    print(Wins.Value) --prints wins
25 
26    Cash.Changed:Connect(function() --when the value of Cash has changed
27        ds1:SetAsync(player.UserId, Cash.Value) --Saves
28    end)
29 
30    Wins.Changed:Connect(function() --When the value of Wins has changed
31        ds2:SetAsync(player.UserId, Wins.Value) --Saves
32    end)
33end)
