Modify the flowchart you created earlier to add more types of behaviors that might enable or disable access to a protected area. It’s your world, so you can change how you want it to work!
Think about the creatures who might inhabit this world and decide whether they might be classified as friend or enemy. How will you know? What patterns will you observe in their behavior to determine their objective? Which ones will protect the petrified wood, and which will try to steal it or inadvertently damage it? Build a flowchart to map out the behaviors of several types of protectors and several potential marauders. You probably guessed it, but your next steps will be to build a game within this world to protect the forest from invaders.
