This article mainly introduces the relevant knowledge of "how to use JAVA to realize the classic game tank war". The editor shows you the operation process through the actual case, the operation method is simple and fast, and the practicality is strong. I hope this article "how to use JAVA to realize the classic game tank war" can help you solve the problem.

Main design

1. There should be difficult levels: the first, the second, the third, the fourth and the fifth; the map of the first level is the simplest, and the map of the fifth level is the most difficult

2. Tanks must have blood strips and fight many times before they will die.

The map requires me to have four of our tanks (equivalent to four lives) and several enemy tanks

4. The number of shells in our tank is fixed, set to 500

5. Basic information is displayed on the right side of the map

6. On the map, there should be bricks, iron and rivers.
