Code¶

Program to Print the String¶

--- print("Hello Senthil")
--

local myString = "Hi my name is Senthil"
print(typeof(myString))
print(myString)

-- This is a number variable

local myInteger = 32.67
print(typeof(myInteger))
print(myInteger)

local myBoolean = true
print(typeof(myBoolean))
print(myBoolean)

Program with Conditional Statement¶

local myString = "Hi my name is Senthil"
local myInteger = 32.67
local myBoolean = true

print(myString)

myString = "My name is now Darth Vader"

print(myString)


if myBoolean == true then
    print("My boolean is true")
else
    print("My boolean is false")
end


if myInteger > 30 then
    print("My integer is greater than 30")
else
    print("My integer is less than 30")
end


if (1 + 1 == 3) then
    print("1 + 1 is 3")
else
    print("1 + 1 is not 3. It is 2")
end

Program with Conditional Statements and Boolean¶

local age = 15
local movieRating = "M"

if age >= 15 then
    print("You can watch the M rated movie")
else
    print("You are too young to watch the M rated movie")
end

movieRating = "G"

if movieRating == "G" then
    print("You can watch the G rated movie")
end

movieRating = "M"

if age >= 15 and movieRating == "M" then
    print("You can watch the M rated movie")
end

Functions¶

local myName = "Senthil"

-- The dot dot symbol is called concatenation operator
local function sayMyName()
    print("My name is " .. myName)
end


sayMyName()

myName = "Kumaran"

sayMyName()

Functions with Parameters¶

local function sayMyName(myName, age)
    print("Hello, " .. myName)
    print("I am " .. age .. " years old")
end

sayMyName("Senthil", 42)

Parameter Strings¶

local function addNums(num1, num2)
    return num1 + num2
end

local answer = addNums(1, 2)

print(answer)

Calculator with String¶

local function addNums(n1, n2)
    return n1 .. " + " ..  n2 .. " = " .. (n1 + n2)
end

local answer = addNums(1, 2)

print(answer)

Part¶

local myPart = script.Parent

myPart.BrickColor = BrickColor.new("Bright red")

myPart.BrickColor = BrickColor.Random()

Workspace¶

local myPart = game.Workspace.Part

myPart.Transparency = 0.5

local myBridge = game.Workspace.Bridge

myBridge.Grass.BrickColor = BrickColor.Random()

When creating a part, make it anchored.

Touching the part¶

local myPart = script.Parent

myPart.BrickColor = BrickColor.Random()

local function partTouchedFunction(partTouched)
    print(partTouched)
end

myPart.Touched:Connect(partTouchedFunction)

Changing Brick Color with Touch¶

local myPart = script.Parent

-- debounce

local db = true

local function partTouchedFunction(partTouched)
    if db then
        db = false
        myPart.BrickColor = BrickColor.Random()
        wait(2)
        db = true
    end
end

myPart.Touched:Connect(partTouchedFunction)

Inline Touch Function¶

local myPart = script.Parent

-- debounce

local db = true

myPart.Touched:Connect(function(partTouched)
    if db then
        db = false
        myPart.BrickColor = BrickColor.Random()
        wait(2)
        db = true
    end
end)

Player touch the part¶

-- Player = This is you!
-- Humanoid - A little robot
-- Character - This is how you look in the game.
--

local myPart = script.Parent

-- debounce

local db = true

myPart.Touched:Connect(function(hit)
    local character = hit.Parent
    local humanoid = character:FindFirstChild("Humanoid")
    if humanoid and db then
        local player = game.Players:GetPlayerFromCharacter(character)
        -- game.Players:FindFirstChild(character.Name)
        db = false
        myPart.BrickColor = BrickColor.Random()
        print(player.Name .. " touched the part!")
        wait(2)
        db = true
    end

end)


-- Test this. Player can change the color of the part by touching it.
-- Moving another block against it will not change the color.

Pick up the Part¶

-- Create a Spawn point.
-- Create a part to pick up. Rename it to "Pickup"
-- Anchored
-- Add a Script and rename it to pickupScript
--
--
local pickup = script.Parent
local db = true

pickup.Touched:Connect(function(hit)
    local character = hit.Parent
    local humanoid = character:FindFirstChild("Humanoid")
    if humanoid and db then
        local player = game.Players:GetPlayerFromCharacter(character)
        -- game.Players:FindFirstChild(character.Name)

        db = false

        pickup.Transparency = 1
        pickup.CanCollide = false

        print(player.Name .. " picked up the part!")

        wait(2)

        pickup.Transparency = 0
        pickup.CanCollide = true

        db = true
    end

end)

Sign to pick up the part¶

-- Create a Spawn point.
-- Create a part to pick up. Rename it to "Pickup"
-- Anchored
-- Add a Script and rename it to pickupScript
--
local sign = game.Workspace.signModel.backboard.SurfaceGui.Frame.TextLabel
local pickup = script.Parent
local db = true

pickup.Touched:Connect(function(hit)
    local character = hit.Parent
    local humanoid = character:FindFirstChild("Humanoid")
    if humanoid and db then
        local player = game.Players:GetPlayerFromCharacter(character)
        -- game.Players:FindFirstChild(character.Name)

        db = false

        pickup.Transparency = 1
        pickup.CanCollide = false

        sign.Text = "You have picked up the item!"

        print(player.Name .. " picked up the part!")

        wait(5)

        pickup.Transparency = 0
        pickup.CanCollide = true

        sign.Text = "Pick up the part!"

        db = true
    end

end)

Camping Project¶

LeaderBoard¶

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)

        local leaderstats = Instance.new("Folder")
        leaderstats.Name = "leaderstats"
        leaderstats.Parent = player

       end)
end)

Log Pickup¶

-- logScript

local log = script.Parent
local db = true

log.Touched:Connect(function(hit)
    local character = hit.Parent
    local hum = char:FindFirstChild("Humanoid")

    if db and hum then
        db = false

        local plr = game.Players:FindFirstChild(char.Name)
        local pStats = plr:WaitForChild("leaderstats")

        log.Transparency = 1
        wait(3)
        log.Transparency = 0

        db = true
    end

end)

Roblox Programming - 2023¶

Pass The Ice Wall¶

-- Add this 1
local wall = workspace.iceWall

local myName = "Bill"
local myAge = 12
local isAllowedToGoCamping = true

-- Add this 3
task.wait(5)

-- Add this 2
if myName == "Bill" then
    print("Yes your name is ", myName)
    wall.Transparency = 0.3
else
    warn("No your name is not Bill")
end

task.wait(5)

if myAge >= 10 then
    print("Yes you are ", myAge, " you are old enough to go camping")
    wall.Transparency = 0.6
end

if isAllowedToGoCamping == true then
    print("Yes you are allowed to go camping")
    wall.Transparency = 1
    wall.CanCollide = false
end
