Using a timer in game lab

I have a student building a game. He wants the backgrounds to change automatically after 60 seconds. He has tried the world.seconds. He cannot get this to work. Any suggestions on how to use a timer to initiate change from one background to another background?

Greetings @leslie.dillon ,

You can use setTimeout like shown below.

background("blue");
setTimeout(function(){
    background("red");
}, 60000); //in ms
