Object Oriented Design Goals Pacman Project Reflections The Sims Project: additional pointers Classes Pacman Ghost Dot Power Maze Fruit Score pill On state diagrams Naming of states: much better! Transitions Need labels! Labels = Event [Guard] / Action If multiple objects are involved: event needs to describe who is involved what happens to whom Describe Event not Method Ghost states: attacking eat fleeing Not clear who is involved Ghost state diagram attacking Power Pill effect is gone (2 secs) Ghost reaches home Pacman eats power pill Returning to ghost home fleeing blinking Power Pill effect fades away (10 secs) fleeing Sequence diagrams Keep general flow left to right What :Pacman makes the ghost go right? :Ghost kill Ok, but not recommended :Ghost :Pacman kill Good The Sims Collaborative Diffusion Search Can be used to build simulations including object interactions even more complex than that found in the Sims Getting started Look at existing AgentSheets projects “Ultimate Pacman” “World Cup” Diffusion Difference Equations Simple u (k=0.25) := 0.25 * (u[left] + u[right] + u[up] + u[down]) General u := @k * (u[left] + u[right] + u[up] + u[down] - 4 * u) + u Where k is The diffusion coefficient Should be < 0.45 Debugging diffusion 3D Plot is only available in research prototype Use colorization Wanted We need one person who would help building an infrastructure (counts as final project).
