Hi, I created a new scenario with the name "CarsRacingScenario".
I deleted the "MyWorld" subclass of the World and created a new subclass of the World and named it "MyRaceWorld". But the world is not shown. I don't know what I am missing.
I know I can instead of deleting the "MyWorld" subclass, I can rename it to "MyRaceWorld", but I want to know why I can't delete it and create another one?
This is how it looks like!
