Python Pygame实现兔子猎人守护城堡游戏

作者：九叔敲代码

这篇文章主要介绍了用python来制作的一个守护类小游戏兔子猎人守护城堡，文中的示例代码介绍得很详细，感兴趣的小伙伴快来跟随小编一起学习学习吧

效果图

守卫类游戏大家应该玩过吧，什么植物大战僵尸呀，保卫萝卜呀，今天我们自己用python来写一个自己的守护类小游戏兔子猎人守护城堡，让大家看看效果图。

主要代码

下面我来说一下是怎么得到的将代码分享一下给大家

首先得将要用到的库导入进来

import cfg
import math
import random
import pygame
from modules.Sprites import *
from modules.interfaces import *

游戏初始化

 初始化pygame, 设置展示窗口

pygame.init()
	pygame.mixer.init()
	screen = pygame.display.set_mode(cfg.SCREENSIZE)
	pygame.display.set_caption(' QQ群号: 932574150')

加载必要的游戏素材

game_images = {}
	for key, value in cfg.IMAGE_PATHS.items():
		game_images[key] = pygame.image.load(value)
	game_sounds = {}
	for key, value in cfg.SOUNDS_PATHS.items():
		if key != 'moonlight':
			game_sounds[key] = pygame.mixer.Sound(value)
	return screen, game_images, game_sounds

主函数

初始化

screen, game_images, game_sounds = initGame()

播放背景音乐

pygame.mixer.music.load(cfg.SOUNDS_PATHS['moonlight'])
	pygame.mixer.music.play(-1, 0.0)

加载字体

font = pygame.font.Font(None, 24)

定义兔子

bunny = BunnySprite(image=game_images.get('rabbit'), position=(100, 100))

跟踪玩家的精度变量, 记录了射出的箭头数和被击中的獾的数量.

acc_record = [0., 0.]

生命值

healthvalue = 194

弓箭

arrow_sprites_group = pygame.sprite.Group()

獾

badguy_sprites_group = pygame.sprite.Group()
	badguy = BadguySprite(game_images.get('badguy'), position=(640, 100))
	badguy_sprites_group.add(badguy)

定义了一个定时器, 使得游戏里经过一段时间后就新建一支獾

badtimer = 100
	badtimer1 = 0

游戏主循环, running变量会跟踪游戏是否结束, exitcode变量会跟踪玩家是否胜利.

running, exitcode = True, False
	clock = pygame.time.Clock()
	while running:

在给屏幕画任何东西之前用黑色进行填充

screen.fill(0)

添加的风景也需要画在屏幕上

		for x in range(cfg.SCREENSIZE[0]//game_images['grass'].get_width()+1):
			for y in range(cfg.SCREENSIZE[1]//game_images['grass'].get_height()+1):
				screen.blit(game_images['grass'], (x*100, y*100))
		for i in range(4): screen.blit(game_images['castle'], (0, 30+105*i))

倒计时信息

countdown_text = font.render(str((90000-pygame.time.get_ticks())//60000)+":"+str((90000-pygame.time.get_ticks())//1000%60).zfill(2), True, (0, 0, 0))
		countdown_rect = countdown_text.get_rect()
		countdown_rect.topright = [635, 5]
		screen.blit(countdown_text, countdown_rect)

按键检测，退出与射击

		for event in pygame.event.get():
			if event.type == pygame.QUIT:
				pygame.quit()
				sys.exit()
			elif event.type == pygame.MOUSEBUTTONDOWN:
				game_sounds['shoot'].play()
				acc_record[1] += 1
				mouse_pos = pygame.mouse.get_pos()
				angle = math.atan2(mouse_pos[1]-(bunny.rotated_position[1]+32), mouse_pos[0]-(bunny.rotated_position[0]+26))
				arrow = ArrowSprite(game_images.get('arrow'), (angle, bunny.rotated_position[0]+32, bunny.rotated_position[1]+26))
				arrow_sprites_group.add(arrow)

移动兔子

key_pressed = pygame.key.get_pressed()
		if key_pressed[pygame.K_w]:
			bunny.move(cfg.SCREENSIZE, 'up')
		elif key_pressed[pygame.K_s]:
			bunny.move(cfg.SCREENSIZE, 'down')
		elif key_pressed[pygame.K_a]:
			bunny.move(cfg.SCREENSIZE, 'left')
		elif key_pressed[pygame.K_d]:
			bunny.move(cfg.SCREENSIZE, 'right')

更新弓箭

		for arrow in arrow_sprites_group:
			if arrow.update(cfg.SCREENSIZE):
				arrow_sprites_group.remove(arrow)

更新獾

		if badtimer == 0:
			badguy = BadguySprite(game_images.get('badguy'), position=(640, random.randint(50, 430)))
			badguy_sprites_group.add(badguy)
			badtimer = 100 - (badtimer1 * 2)
			badtimer1 = 20 if badtimer1>=20 else badtimer1+2
		badtimer -= 1
		for badguy in badguy_sprites_group:
			if badguy.update():
				game_sounds['hit'].play()
				healthvalue -= random.randint(4, 8)
				badguy_sprites_group.remove(badguy)

碰撞检测

		for arrow in arrow_sprites_group:
			for badguy in badguy_sprites_group:
				if pygame.sprite.collide_mask(arrow, badguy):
					game_sounds['enemy'].play()
					arrow_sprites_group.remove(arrow)
					badguy_sprites_group.remove(badguy)
					acc_record[0] += 1

画出弓箭

arrow_sprites_group.draw(screen)

画出獾

badguy_sprites_group.draw(screen)

画出兔子

bunny.draw(screen, pygame.mouse.get_pos())

画出城堡健康值, 首先画了一个全红色的生命值条, 然后根据城堡的生命值往生命条里面添加绿色.

screen.blit(game_images.get('healthbar'), (5, 5))
		for i in range(healthvalue):
			screen.blit(game_images.get('health'), (i+8, 8))

判断游戏是否结束

		if pygame.time.get_ticks() >= 90000:
			running, exitcode = False, True
		if healthvalue <= 0:
			running, exitcode = False, False

更新屏幕

pygame.display.flip()
		clock.tick(cfg.FPS)

计算一下游戏的准确性

accuracy = acc_record[0] / acc_record[1] * 100 if acc_record[1] > 0 else 0
	accuracy = '%.2f' % accuracy
	showEndGameInterface(screen, exitcode, accuracy, game_images)

运行 

if __name__ == '__main__':
	main()

上面我将代码分散了，大家可以看一下整合一下就可以运行了
