The Game Over creating with audio?

Hello? I added to my player life textures on the screen, the GUI textures. Now when my bar reaches zero, I would like to place a script on the screen appear the words I (GAME OVER) with not only audio source to understand more as a variable in the script. How can I do? There is already a script like this you know?

you could have a gui.label or something on your camera
but will sit under an if statement to check if life is 0

or when life is 0 instantiate some 3d text or something

that’s the basic theory… im not gonna right the code for ya
