This code implements a countdown timer using a Lua script. Here's what it does:

1. Initialize Timer:

   • local timer = 20: A local variable timer is initialized to 20, representing the number of seconds for the countdown.

2. RunTimer Function:

   • function RunTimer(): A function named RunTimer is defined, which houses the countdown logic.

3. Countdown Logic:

   • while timer > 0 do: A while loop is used to continuously execute its body as long as the value of timer is greater than 0.
   • wait(1): This pauses the execution of the script for 1 second (assuming wait() is a function that introduces a delay; it’s often used in game engines like Roblox).
   • timer = timer-1: After each 1-second delay, the value of timer is decremented by 1.

4. Result:

   • When the RunTimer function is executed, it will count down from 20 to 0, pausing for 1 second between each decrement. Once timer reaches 0, the loop stops, and the countdown is complete.

Note: This code snippet doesn't handle what happens after the countdown completes, and there may be errors depending on the runtime environment or if wait(1) isn't a defined function in the given context.
