前言

嗨喽~大家好呀，这里是魔王呐 !

这个小恐龙熟悉叭，相信你在摸鱼得时候玩过它~

这是谷歌流量器中很有名的彩蛋：当你网络出现问题时，就会出现一个“小恐龙游戏”。

当然你如果想要直接进行游戏，可以在地址栏输入：chrome://dino

那么今天我们得目的就是：用python来制作一个仿制的“小恐龙游戏”！

开发工具：

Python版本：3.6.4

相关模块：

pygame模块；以及一些python自带的模块。

如果安装python第三方模块:

1. win + R 输入 cmd 点击确定, 输入安装命令 pip install 模块名 (pip install pygame) 回车

2. 在pycharm中点击Terminal(终端) 输入安装命令

准备素材

图片

音乐

代码

运行代码文件：Game7.py

导入模块

import cfg
import sys
import random
import pygame
from modules.sprites.scene import *
from modules.sprites.obstacle import *
from modules.sprites.dinosaur import *
from modules.interfaces.gameend import GameEndInterface
from modules.interfaces.gamestart import GameStartInterface

需要源码、素材可直接查看文章下方推广加助理小姐姐V免费获取呐~

游戏初始化

'''main'''
def main(highest_score):
	pygame.init()
	screen = pygame.display.set_mode(cfg.SCREENSIZE)
	pygame.display.set_caption('T-Rex Rush —— 青灯教育 小恐龙')

导入所有声音文件

	sounds = {}
	for key, value in cfg.AUDIO_PATHS.items():
		sounds[key] = pygame.mixer.Sound(value)

游戏开始界面

	GameStartInterface(screen, sounds, cfg)

定义一些游戏中必要的元素和变量

	score = 0
	score_board = Scoreboard(cfg.IMAGE_PATHS['numbers'], position=(534, 15), bg_color=cfg.BACKGROUND_COLOR)
	highest_score = highest_score
	highest_score_board = Scoreboard(cfg.IMAGE_PATHS['numbers'], position=(435, 15), bg_color=cfg.BACKGROUND_COLOR, is_highest=True)
	dino = Dinosaur(cfg.IMAGE_PATHS['dino'])
	ground = Ground(cfg.IMAGE_PATHS['ground'], position=(0, cfg.SCREENSIZE[1]))
	cloud_sprites_group = pygame.sprite.Group()
	cactus_sprites_group = pygame.sprite.Group()
	ptera_sprites_group = pygame.sprite.Group()
	add_obstacle_timer = 0
	score_timer = 0

游戏主循环

	clock = pygame.time.Clock()
	while True:
		for event in pygame.event.get():
			if event.type == pygame.QUIT:
				pygame.quit()
				sys.exit()
			elif event.type == pygame.KEYDOWN:
				if event.key == pygame.K_SPACE or event.key == pygame.K_UP:
					dino.jump(sounds)
				elif event.key == pygame.K_DOWN:
					dino.duck()
			elif event.type == pygame.KEYUP and event.key == pygame.K_DOWN:
				dino.unduck()
		screen.fill(cfg.BACKGROUND_COLOR)

–随机添加云

		if len(cloud_sprites_group) < 5 and random.randrange(0, 300) == 10:
			cloud_sprites_group.add(Cloud(cfg.IMAGE_PATHS['cloud'], position=(cfg.SCREENSIZE[0], random.randrange(30, 75))))

–随机添加仙人掌/飞龙

		add_obstacle_timer += 1
		if add_obstacle_timer > random.randrange(50, 150):
			add_obstacle_timer = 0
			random_value = random.randrange(0, 10)
			if random_value >= 5 and random_value <= 7:
				cactus_sprites_group.add(Cactus(cfg.IMAGE_PATHS['cacti']))
			else:
				position_ys = [cfg.SCREENSIZE[1]*0.82, cfg.SCREENSIZE[1]*0.75, cfg.SCREENSIZE[1]*0.60, cfg.SCREENSIZE[1]*0.20]
				ptera_sprites_group.add(Ptera(cfg.IMAGE_PATHS['ptera'], position=(600, random.choice(position_ys))))

–更新游戏元素

		dino.update()
		ground.update()
		cloud_sprites_group.update()
		cactus_sprites_group.update()
		ptera_sprites_group.update()
		score_timer += 1
		if score_timer > (cfg.FPS//12):
			score_timer = 0
			score += 1
			score = min(score, 99999)
			if score > highest_score:
				highest_score = score
			if score % 100 == 0:
				sounds['point'].play()
			if score % 1000 == 0:
				ground.speed -= 1
				for item in cloud_sprites_group:
					item.speed -= 1
				for item in cactus_sprites_group:
					item.speed -= 1
				for item in ptera_sprites_group:
					item.speed -= 1

–碰撞检测

		for item in cactus_sprites_group:
			if pygame.sprite.collide_mask(dino, item):
				dino.die(sounds)
		for item in ptera_sprites_group:
			if pygame.sprite.collide_mask(dino, item):
				dino.die(sounds)

–将游戏元素画到屏幕上

		dino.draw(screen)
		ground.draw(screen)
		cloud_sprites_group.draw(screen)
		cactus_sprites_group.draw(screen)
		ptera_sprites_group.draw(screen)
		score_board.set(score)
		highest_score_board.set(highest_score)
		score_board.draw(screen)
		highest_score_board.draw(screen)

–更新屏幕

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

–游戏是否结束

		if dino.is_dead:
			break

游戏结束界面

	return GameEndInterface(screen, cfg), highest_score

'''run'''
if __name__ == '__main__':
	highest_score = 0
	while True:
		flag, highest_score = main(highest_score)
		if not flag: break
