This article mainly introduces "Java how to achieve the upgraded version of the cuckoo clearance game". In the daily operation, I believe that many people have doubts about how to achieve the upgraded version of the cuckoo clearance game in Java. The editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to achieve the upgraded version of the cuckoo clearance game in Java". Next, please follow the editor to study!

Preface

"cuckoo clearance-upgrade version" is a java-based cuckoo clearance game, the left mouse button click to control the position of the bird through the gap between the pipes, need to do collision detection, monitoring keyboard events, background picture switching, obstacles pipeline generated on the y-axis need random position.

Main design

1. Design the game interface and implement it with swing

two。 Design background

3. Design moving wall

4. Design cuckoo

5. Design obstacles

6. Design background music and sound effects

7. Add user account registration and login function

8. Reference mysql database, manage user account passwords and store ranking information

The database "game" needs to be created in advance, and the character set is selected "utf8mb4".

Then execute the mysql table structure and initialize the data script

Modify the parameter values of DBUtils in the code

9. New game mall module

10. New ranking module
