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。
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 *
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
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)
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
