In this I will show you examples of all the kinds of loops RBX.lua has to offer.

While-do

While-do, more commonly known as while true do, is one of the most used loops. The reason being is that most scripters on Roblox only know about it, no other loops. The way to use this loop is to put something in between while and do. If whatever is in between the two is true, then it will continue. You must end the loop with an 'end'

Code:

while true do wait() print("Hello World") end

Repeat-until

Repeat-until is another loop in RBX.lua. It repeats itself until its requirement is fulfilled.

Code:

repeat wait() print("Hello World") until 1 ~= 1

for-do

I use this to repeat something a specific amount of times, like if I wanted to make a script that counted down until it printed 'hi'

Code:

for i = 10,1,-1 do print(i.. " second(s) until I print hi") wait(1) end print("hi")

pairs loop

One of the more complex loops. This is used to run through an array and interact with its contents. 'i' is the number the script is on, 'v' is the object itself:

Code:

m = {"cookie","Milk","Cake") for i,v in pairs(m) do if v == "cookie" then print("I ate my " ..v) end end

The only code i get is while true do i dont quite get 'for i = 10,1,-1 do
print(i.. " second(s) until I print hi")
wait(1)
end
print("hi")'

you should change While-do to while loops and For-do for loops. pairs is just a method of indexing through tables. watch me put caps in certain words of this line using pairs:

FOR i,v in pairs(table) DO

notice how it's still a for loop. 0.o

To make the for do loop easier to understand you would say

For loop makes a command or commands go a set of number of times

better example

Code:

L = 10 for i = 1, L do print("Hey") end end

Also naknak i and v are just vairable names you can set different variables to it as long as the code is defined correctly.

I think that the pairs loops is really a for loop.

I never said anything about i and v not being changeable. Pairs is really a for loop, but it is best to understand them separately.

Just thought I would point out some technical stuff.

Fair enough.

I think that you may want to add that you need a minimum of wait() in the while loops.

"if v.Name == "cookie" then"

you mean

if v == "cookie" then

Whoops. Yes.
