Can somebody explain how to use a 'for' loop?
How do you use a for loop, in lua?

An example of a for loop would be
1 | for i = 1, 10 do |
2 | print(i.." ") |
3 | end |
and it would OUTPUT 1 2 3 4 5 6 7 8 9 10
The "i" can actually be anything, you could actually just name it "BugQuestioner" and if you refer to it later as BugQuestioner it will work. Also the 1 after the equals is the initial starting value and the number after the comma is the end value. If you want it to count down you can switch the 1 and the 10 and add another comma and put -1 because that's the number it will increment by. If you don't set the increment it will default to 1.
Okay, so here is how it is written first of all.
1 | myTable = {1,2,3,4,5} |
2 |
3 | for i,v in pairs(myTable) do |
4 | print(v) |
5 | end |
So i'm assuming you learned what a table is. If not here's what it is: A table is a variable that contains numbers,strings etc. It could hold anything as long as it has a value.
A For Loop loops through the table, by going through each object/string/number within. V represents the object it's currently counting.
So this will print 12345. But not in any order. That's what table.Sort() is for.
1 | myTable = {1,2,3,4,5} |
2 |
3 | for i,CurrentObject in pairs(InsertTableNameHere) do |
4 | print(v) -- Loops through all objects in the table and will print each one. |
5 | end |
Hope i helped.
