What steps can be taken to ensure that whenever an event occurs, a screenGui element becomes visible to all players?

edit

Create a ScreenGui element that contains the information or image that needs to be shown to players whenever an event occurs.

Use a RemoteEvent or RemoteFunction to send a message to the server indicating that the event has occurred.

In the server script, listen for the RemoteEvent or RemoteFunction call and trigger the ScreenGui to become visible.

Use a loop to iterate through all players in the game and set the ScreenGui element's Visible property to true for each player.

Make sure to include a check to ensure that the ScreenGui element is not already visible before attempting to make it visible again.

Include a timeout feature that automatically hides the ScreenGui after a certain amount of time to prevent clutter and ensure that players can continue playing the game without any distractions.
