The pictures needed for the game are placed at the end, and the pictures needed for the game are taken , The game is divided into three levels , Three types of difficulties: ordinary and simple . The game code is divided into seven categories . I put the pictures needed by the game at the end .
The screenshot of the game is as follows :
The game is divided into three levels
This is a simple level
This is an ordinary level
This is the most difficult level
Step on the thunder and lose directly , In the upper left corner is the number of mines . The upper right corner is the timing function , In the middle is the start button. After failure, click to restore the level and continue to break through the level .
The test class code is as follows , This class is mainly used to run and call other classes .
