I chose challenge 1, having foxes chase rabbits when they get close, and rabbits flee. Rabbits also move towards grass when they are close. I chose this because I wanted to find challenges that would be accessible to my struggling students. I don't think this was easy, but with scaffolding they could enjoy it and be successful.
I struggled a bit to find code blocks that would help. I started with the idea of computing the distance in absolute value between x and y coordinates of the agents, but was unsure how to detect the other agent's traits. Perhaps this can be done, I'll investigate later. I used the SLNova cookbook to find a better way to chase. This showed me interesting movement and detection code blocks I hadn't used yet. I think using the cookbook could be good for my students, if they are using it with critical thinking to explore new code blocks and how to solve challenges. I don't need help at this time.
