Lua for i,v tutorial

-- How to use for i,v loops and what are they?

-- if i say something wrong pls dm python#9373

-- for i,v in pairs() is used to loop through a table
-- If you don't know what tables are have a look at this: https://www.lua.org/pil/2.5.html

-- Let me show you something:
for i,v in pairs(game.Workspace:GetDescendants()) do
   print(i.. " - " ..v)
end

-- This program loops through the workspace and gets everything
-- The i stands for index, some people call it key so they do k,v instead of i,v
-- and the v stands for Value

-- I print the index concatenated with a dash and the value


-- So lets say the Baseplate
-- It could be the 3rd object inside of the workspace since the Terrain and Camera (I  think) are first

-- So while looping, the index will be 3 when at the Baseplate and the value will be the Baseplate

-- You can do many things with this (exploiters use this alot to their advantage by doing something like below)

for i,v in pairs(game.Workspace.Coins:GetChildren()) do -- Looping through a possible folder in the game called coins
   if v:IsA("BasePart") and v.Name == "Coin" then -- If the object is a part and its name is 'Coin'
        v.CFrame = game.Players.LocalPlayer.Character.HumanoidRootPart.CFrame -- They will make it teleport to them
   end -- The end of the 'if statement'
end -- The end of the loop thing

-- But this is also super helpful for game developers

for i,v in pairs(game.Workspace.Lava:GetChildren()) do -- Looping through a folder in the workspace called 'Lava'
        if v:IsA("BasePart") and v.Name == "Lava" then -- If the object is a part and its name is 'Lava'
            v.Touched:Connect(function(object) -- Then when it's touched
                if object.Parent:FindFirstChild("Humanoid") then -- If the object that touched it has a humanoid
                    object.Parent.Humanoid.Health = 0 -- We will set the health to 0, killing them
                end -- end of 'if statement'
            end) -- end of function (.Touched event)

        end -- end of 'if' statement
end -- end of for i,v loop thing

--[[
If this was hard to follow, I understand; my explaining was kinda bad (really bad)
Dm me at python#9373 if u want more info

-- Also you can loop through almost anything, not just workspace objects or workspace

-- quick example:

for i,v in pairs(game.Lighting:GetDescendants()) do -- Looping through Lighting
   if v.Name == "Beams" and game.Players.LocalPlayer.Graphics.Value == "Low" then
        v:Destroy()
   end
end
