2. Coordinates and Direc3ons

3. 3 Parts of a Robot
• All of them can rotate independently

4. Movement
• Time is measured in turns (“3cks”).
• Distance is measured in pixels.
• Robot can move no farther than 8 pixels per
turn. If commanded to move farther, it will
take several turns.
• The same goes for turning of body parts.

5. Firing
• Bullets can have power of 0.1‐3
• Firing a bullet costs an equal amount of HP
• But a hit “leechs” back HP
• Weak bullets move faster

6. Coding
• Main loop: what to do each turn
• Events: what to do when something happens
– onScannedRobot
– onHitByBullet
– onHitRobot
– …
• See the javadoc directory in the installa3on
folder for reference

9. Some angles from last slides explained

10. Trick: Linear Aim‐ahead
• Assume the enemy moves in straight line with
constant speed (very effec3ve against human
player)
