This article is about how Python Pygame implements the fruit ninja game. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. 1.0 rules of the game in preparation

Python version of the fruit ninja editor initialization setting is the player's 3 health points, cut to the corresponding fruit points, cut to explosive

For example, bombs will correspondingly reduce health, in the value of life can always be cut, the more cut, the higher the score, the corresponding health depletion is the end of the game! Try it. How many points can you get?

Ha, today also recorded a game video, watching the video has a more feeling of playing games.

1.1 Game picture material (modifiable)

1.2 game font material (modifiable)

II. Environmental installation

This article is written by Python3 and Pycharm. Modules Pygame, random randomly appear fruit and some of their own.

Here the module installation command unifies the image source Douban:

Pip install-I https://pypi.douban.com/simple/ + module name

Third, start tapping code 3.0 to set the interface player health, such as player_lives = 3 # life score = 0 # score fruits = ['melon',' orange', 'pomegranate',' guava' 'bomb'] # Fruit and bomb 3.1 Import module import pygame, sysimport osimport random3.2 interface background, font setting background = pygame.image.load (' background image / 02.png') # background font = pygame.font.Font (os.path.join (os.getcwd (), 'font / comic.ttf') 42) # Font score_text = font.render ('Score:' + str (score), True, (255,255,255)) # Font style 3.3 Game window sets the frame rate of WIDTH = 800HEIGHT = 500FPS = 12 # gameDisplay Refresh pygame.init () pygame.display.set_caption ('fruit ninja _ csdn account: Gu Muzi A') # title gameDisplay = pygame.display.set_mode ((WIDTH) HEIGHT) # Game window clock = pygame.time.Clock () 3.4 randomly generated fruit location and data storage def generate_random_fruits (fruit): fruit_path = "images/" + fruit + ".png" data [fruit] = {'img': pygame.image.load (fruit_path),' x': random.randint (100500) # position of the fruit on the x axis' yearly: 800,' speed_x': random.randint (- 10 speed_x': random.randint 10), # speed and diagonal movement of the fruit in the x direction 'speed_y': random.randint (- 80,-60), # speed in the y direction' throw': False # if the location where the fruit is generated is outside gameDisplay Will be discarded 'tweets: 0,' hit': False,} if random.random () > = 0.75: # returns the next random floating point in the range of [0.0,1.0] to keep the fruit displayed in the game.

Game display effect

4.1 Part 1 dynamic video shows the following results

Video link

Python version of fruit ninja, fun ~

4.2 Part 2 static screenshot shows the effect as follows

(1) the game enters the interface--

(2) modify the interface entered by the background image-this feels better.

4.3 the screenshot of Part 3 statically entering the game interface is as follows
