Introduction

In C# and Unity, loops are used to execute a block of code multiple times. There are several types of loops that we can use in Unity. Let’s discuss them below.

The for loop

Developers use the for loop to repeat a set of instructions a specific number of times. Here’s the syntax for a for loop:

C#
for (int i = 0; i < 10; i++)
{
    Debug.Log(i);
}

In this example, the for loop will repeat the Debug.Log(i) statement ten times. The loop starts with the variable i set to 0 and will continue as long as i is less than 10. After each iteration, i is incremented by 1. ...
