8. Some Mistakes I made
which gave me Experiences
• collideWith(Thing thing), not collideWithTank()
• override and overload: collideWith(List<Thing> things),
and collideWith(Thing thing)
• Iterator: CurrentModifiedException
• A bullet shoot 2 blocks: test if damaged in the collision
detector
• Jar file did not work: how to get the path name, how to
read from a URL, pay attention to the upper case and
lower case, e.g: Bigleg_strip24.png vs BigLeg_strip24.png

9. What should be Improved
• Polish the game:
• Bounding box or bounding circle should get smaller to
get more accurate collision.
• After tank get a new life, additional weapon should be
clear.
• Create more levels
• Add more weapons to make the game more stimulating
