Decorate your scene

- Create a Material in Project / Create button, assign it a different color, and drag it onto some of your ground cubes to make them more distinctive.
It can’t be turtles all the way down
Have you noticed that if you fall off the edge of your ground cube, you fall forever?
- You could make wider ground and put more bigger cubes below to catch you, but players will always find a way to go where they shouldn’t.
- Next, we’ll add a trigger script to stop players from falling infinitely off the edge.
