Python routine: Mary's adventure

---

Instructions for using the "Mary's Adventure" program

Run "Mary's Adventure" in PyCharm to enter the main game interface as shown in Figure 1.

Figure 1 Game main interface

The specific operation steps are as follows:
(1) After the game's main form interface is displayed, the background map of the game will be automatically loaded and moved. At this time, pipes and missile obstacles will appear randomly. things. When encountering an obstacle, press the space key on the keyboard and Mary will jump, as shown in Figure 2.

Figure 2 Little Mary jumps

(2) Whenever an obstacle is crossed, the points in the upper right corner will automatically increase by 1 point. As shown in Figure 3.

Figure 3: Increase points by overcoming obstacles

(3) If Mary accidentally hits an obstacle while moving, the text "Game Over" will be displayed in the middle of the main game interface. As shown in Figure 4.

Figure 4 Game over

After the game is over, pressing the space bar again will restart the game.
(4) If you do not need to play the background music of the game, you can click the music button in the upper left corner. When the background music is playing, the operating effect of the control button is shown in Figure 5. When the background music stops, the operating effect of the control buttons is shown in Figure 6.

Development environment requirements

The software development and operating environment of this system are as follows.
Operating system: Windows 7, Windows 8, Windows 10.
✓Python version: Python 3.7.0.
✓Development tool: PyCharm.
Python built-in modules: itertools, random.
Third-party module: pygame.
Note: When using a third-party module, you first need to use the pip install command to install the module. You can execute the following command in the Python command window:

pip install pygame

Run method

(1) Start the PyCharm development tool and click the "open" button to open the project source code, as shown in Figure 1.

Figure 7 Open the project source code

(2) After the project source code is opened, open the marie.py file, right-click the file, and select "Run marie" in the pop-up shortcut menu, as shown in Figure 2.

Figure 8 Select “Run marie”

(3) After the project source code is started normally, the main form interface as shown in Figure 3 will be displayed.
