What is a loop?
A loop is a block of code that will run indefinitely unless told to stop.
What kind of loops are there?
There are 3 main types of loops. For, While, and Repeat. Each of them work very differently.
For
A For loop is a loop that will loop a defined amount of times. There a quite a few different ways to do this, which is why I recommend looking at the wiki. For example:
2 | print("This is the for loop") |
While
A While loop is a loop that will run indefinitely, until told to stop. The ways to stop a while loop are either to make it a variable loop or break it. And you always need a wait() function. Example:
02 | local changepart = game.Workspace.Part |
06 | if changepart.Changed then |
Repeat
A Repeat loop is a loop that will run until a condition is met. This is particularly useful when seeing if a LocalPlayer is there. The following example must be in a LocalScript.
1 | local players = game:GetService("Players") |
3 | repeat wait() until players.LocalPlayer |
5 | local player = players.LocalPlayer |
Pros and Cons of Loops
Loops are very efficient ways of indexing tables, counting up or down, or smoothly CFraming. They also minimize code, so you can do more with less.
Loops are also very resource consuming, depending on the loop. Do not ever do a loop without a wait() inside. This can cause studio to crash, and make you lose your hard work.
