Math Operations

x + y	Adds x and y
x - y	Subtracts y from x
x * y	Multiplys the x by y
x / y	Divides x by y
x % y	Remainder of x divided by y

Math Functions

math.random(x,y)	Returns a random number between x and y
math.floor(x)	Rounds down x
math.ceil(x)	Rounds up x
math.abs(x)	Returns the absolute value of x
math.sqrt(x)	Returns the square of x
math.pi	Returns pi

Basic Refrences

.game	Parent of all running game services
.workspace	Refrences Workspace, circumvents game.Workspace
.script	Refrences the script itself
.parent	Refrences the parent of an object

For Loops

for i = start, end, count do
    --Code
end

for i = 1, 5 do
    print("Iteration:", i)
end

local fruits = {"Apple", "Banana", "Cherry"}
for index, value in ipairs(fruits) do
    print(index, value)
end

While Loops

while condition do
    -- Code
end


local counter = 1
while counter <= 5 do
    print("Count:", counter)
    counter = counter + 1 -- Increment the counter to avoid an infinite loop
end

Wait routines

wait()	Pauses the execution of the script for a set duration. Tied to game framerate
task.wait()	Pauses the execution of the script for a set duration. More acurated, Independent of framerate.
task.delay()	Runs a function after a specified delay but does not block the current script.
RunService.Heartbeat	Creates a custom wait loop. High precision, frame-dependent tasks.
Debris:AddItem()	Used for timed object destruction but can act as a timer mechanism.

Basic Threading

task.spawn()	Runs a function in a new thread after yielding briefly (~1/30th of a second)
task.defer()	Schedules a function to run in a new thread without yielding at all. It is executed after the current thread completes.
coroutine.create()	Creates a new coroutine that is paused until explicitly resumed.
coroutine.resume()	Resumes a paused coroutine.
coroutine.yield()	Pauses the current coroutine until it is resumed again.
coroutine.status()	Returns the status of a coroutine ("suspended", "running", or "dead").
coroutine.wrap()	Creates a coroutine and returns a function that, when called, resumes the coroutine.
