Loops and Arrays | Unity C# Basics Part 2
Published: 22 Feb 2022
Learn about some critical fundamentals - Arrays and Loops. They usually go hand in hand so it just felt right to talk about them together. In this tutorial, aimed at absolute beginners who have very little to no coding experience whatsoever, you'll learn:
⚫ What Loops are.
⚫ What kinds of Loops are available in C#
⚫ A step-by-step breakdown of what each statement is doing, why it's happening, and how it works.
⚫ How to make multiple TextMeshProUGUI components on the screen count up over time from a single script

Tip: There's a bunch of ways to approach this, but one way that I like to do it takes advantage of a handy "remainder" operator called the modulus operator: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/arithmetic-operators#remainder-operator-
Update this script so will display the updated TimeDisplay on only a single TextMeshProUGUI component on a frame.
On frame 1, the first TextMeshProUGUI component should display the TimeDisplay
On frame 2, the second TextMeshProUGUI component should display the updated TimeDisplay, the first TextMeshProUGUI component should still show the last TimeDisplay value.
On frame 3, the third TextMeshProUGUI component should display the updated TimeDisplay, the first TextMeshProUGUI component should still show the first TimeDisplay value, and the second TextMeshProUGUI component should display the last value.
etc... through the end of the TextMeshProUGUI components. Once we've reached frame 8 (since we only have 7 TextMeshProUGUI components) it should update the first TextMeshProUGUI component again and continue with this pattern.
This should work for any number of TextMeshProUGUI components, or any size of the Texts array.
