One-Shot CS 175: Project in AI (in Minecraft)
Once upon a time…
There was a little boy called Q. He lived in a wonderland named DBH. People in DBH live happily together. They sing, they dance, and they code together! Suddenly, a group of mob broke into the village, they rob and bully the residents in DBH. From then on, mob came to the village occasionally. Q cannot stand mobs bullying their family and friends. He decides to learn archery to defense the mobs and protect the residents in DBH. However, Q doesn’t have that much arrows. Our job is to help Q to improve his archery skill so that he can kill the mob using fewest arrows. We used Q-learning from Reinforcement learning to achieve this goal. And we received a pretty good result

Goal
First goal of our project is to let the agent to shoot a motionless target:
As the graph shown above, the target is standing right in front of us. Agent can only change it’s up/down angle to aim at the mob.
Second goal of our project is to let the agent to shoot a moving-horizontally target:
More goals are coming!
Environment setting
We’re have two rectangle stages separated by a 2 block-length air gap, where Mob is standing on one stage, agent is facing the mob on the other. We chose Zombie as the Mob(target). Zombie has a 15 life long(3 shot). Time is set to sunset so that Zombie can still live. Peacons and Glowstone are used as our light resource.
