The document discusses using PGraphics objects as image layers or off-screen buffers for collision detection based on distance vs. color. It recommends tackling problems one object at a time by defining its data, methods, and constructor through pseudo-coding before writing real code. A demo refactors Pong and adds reset, pause, and countdown game methods. The next steps are to read about algorithms, debugging, and libraries and decide plans for Friday.
18. Algorithms
- 1. From last time… • Using the PGraphics object as image layers or off-screen image buffers! • Collision detection based on distance vs. color–using an off-screen image buffer! • Iteration 1 graded and returned via email
- 3. Pseudo-coding 1. Tackle one object at a time! 2. Decide what it needs to know (its data), what it needs to do (its methods), and how it needs to be built initially (its constructor)! 3. Write pseudo-code first, then translate it into real code in small chunks
- 5. Demo! Add Game Methods 1. Reset! 2. Pause! 3. Count Down
- 6. For next time… • Read Shiffman, p. 178–198 (Algorithms II, Debugging, & Libraries)! • Decide what to do about Friday…
