There are two types of loops, a numeric for loop, and a generic for loop. They are both mainly used for iterating through tables of different kinds. Although the numeric for loop is also commonly used for countdowns.
Generic For
1 | local tab={"Hello"} |
2 | for index, value in pairs(tab) do |
3 | print(index, value) |
4 | end |
Will print "1 Hello."
Numeric For
1 | local tab={"Hello"} |
2 | for index=1, #tab do |
3 | print(index, tab[index]) |
4 | end |
Will print "1 Hello" as well.
Countdown
1 | local t=30 --time to countdown from |
2 | for index=t, 1, -1 do |
3 | print(index) |
4 | wait(1) |
5 | end |

For loops can be used for many things, like irritating through tables or making a loop go 10 times.
--This loop goes through a table and prints its index and value.
1 | myTable = {"Thetacah", "Josh", "John"}; |
2 | for i, v in pairs(myTable) do |
3 | wait(1) |
4 | print(i..v) |
5 | end |
--This loop will print one through ten since it runs 10 times and i is the value of the ammount of times the loop runs.
1 | for i = 1, 10 do |
2 | wait(1) |
3 | print(i) |
4 | end |
