Creating a Forest

Let's use some command to make a forest and make the entire world green!

• ⚠️ Try the command first! Click here if you need a hint.

⁉️ Hold up. Forests aren't all trees...

We need some way for some of the patches to be green, while the other stay black. Sometimes there's random dirt or rocks where fires shouldn't spread.

How should we address this?

Randomness

In the command center:

> show random 6

• ❓ What did you get?

Random numbers are super useful. Imagine you played a game that was the exact same every time: that wouldn't be any fun at all. Our world is filled with random things that random people do that have random results. Randomness is essential to building NetLogo models!

• ❓ What if we wanted a different range of numbers?
