The provided Lua code creates a timer that counts down from 20 seconds and displays a message when the countdown ends. Here's an explanation of what it does:

1. Initialize the timer: local timer = 20 sets the initial value of the timer to 20 seconds.

2. Define the RunTimer function:

   • Inside this function, a while loop continuously checks if the timer is greater than 0.
   • The wait(1) function pauses the loop for 1 second (presumably from a framework like Roblox where wait is defined).
   • After waiting 1 second, the timer variable is decremented by 1 with timer = timer - 1.

3. Print the end message:

   • Once the timer reaches 0, the loop ends, and it prints "The time is over!".

4. Call the RunTimer function: Finally, the RunTimer function is executed, starting the countdown.

Summary:

This code creates a simple countdown timer starting from 20 seconds, decrementing every second, and prints "The time is over!" when the countdown reaches 0.
