使用pygame製做打地鼠遊戲

一、運行結果預覽

開始界面

第一關

第二關

第三關

第四關

第五關

遊戲結束

二、遊戲功能介紹

2.1開發環境：

python版本：python3.7python

2.2相關模塊：

pygame模塊，以及一些Python自帶的模塊。ios

2.3遊戲介紹：

遊戲採用120秒計時進行，dom

前40秒爲第一關，老鼠的出現速度爲很慢；ide

40-60秒爲第二關，老鼠的出現速度爲慢；函數

60-80秒爲第三關，老鼠的出現速度爲中等；字體

80-100秒爲第四關，老鼠的出現速度爲快；ui

100秒後爲第五關，老鼠的出現速度爲很快；rest

倒計時結束時候遊戲結束，比較分數。code

三、開發思路

3.1定義的py文件

3.1.1 mouse.py（主函數入口）

經過mouse.py文件進行整個打地鼠功能的連接。orm

3.1.2cfg.py文件（字體等基礎配置）

cfg文件中定義了基礎的配置，字體，顏色，大小等等

3.1.3mole.py文件（地鼠）

mole定義了地鼠，包括地鼠的圖片加載，地鼠的顯示，重置等

3.1.4hammer.py文件（錘子）

hammer定義了錘子，包括錘子的圖片加載，錘子的顯示，擊中時的效果，重置等

3.1.5endinterface.py文件（結束界面）

endinterface定義告終束時候的頁面，包括分數顯示和最高分顯示

3.1.6startinterface.py文件（開始界面）

startinterface定義了開始的頁面。

3.2定義的函數

3.2.1遊戲初始化

def initGame():
	pygame.init()
	pygame.mixer.init()
	screen = pygame.display.set_mode(cfg.SCREENSIZE)
	pygame.display.set_caption('袁鑫張晨恩的打地鼠遊戲')
	return screen

3.2.2遊戲的主要入口

def main():

3.2.3 遊戲中老鼠類

class Mole(pygame.sprite.Sprite):

3.2.4 遊戲中錘子類

class Hammer(pygame.sprite.Sprite):

3.2.5 遊戲中開始界面

def startInterface(screen, begin_image_paths):

3.2.6 遊戲中結束界面

def endInterface(screen, end_image_path, again_image_paths, score_info, font_path, font_colors, screensize):

四、相關代碼

4.1mouse.py（主函數入口）

def main():
	# 初始化
	screen = initGame()

4.1.1 加載背景音樂和其餘音效

pygame.mixer.music.load(cfg.BGM_PATH)
	pygame.mixer.music.play(-1)
	audios = {
				'count_down': pygame.mixer.Sound(cfg.COUNT_DOWN_SOUND_PATH),
				'hammering': pygame.mixer.Sound(cfg.HAMMERING_SOUND_PATH)
			}

4.1.2加載字體

font = pygame.font.Font(cfg.FONT_PATH, 40)

4.1.3 加載背景圖片

bg_img = pygame.image.load(cfg.GAME_BG_IMAGEPATH)

4.1.4 開始界面

startInterface(screen, cfg.GAME_BEGIN_IMAGEPATHS)

4.1.5 地鼠改變位置的計時

hole_pos = random.choice(cfg.HOLE_POSITIONS)
	change_hole_event = pygame.USEREVENT
	pygame.time.set_timer(change_hole_event, 800)

4.1.6 地鼠

mole = Mole(cfg.MOLE_IMAGEPATHS, hole_pos)

4.1.7 錘子

hammer = Hammer(cfg.HAMMER_IMAGEPATHS, (500, 250))

4.1.8 時鐘

clock = pygame.time.Clock()

4.1.9 分數

your_score = 0

4.1.10 關卡

number = 1
	flag = False

4.1.11 遊戲主循環

while True:
		# --遊戲時間爲120s
		time_remain = round((121000 - pygame.time.get_ticks()) / 1000.)

4.1.12 遊戲時間減小, 地鼠變位置速度變快

# 第一關
		if time_remain == 100 and not flag:
			hole_pos = random.choice(cfg.HOLE_POSITIONS)
			mole.reset()
			mole.setPosition(hole_pos)
			pygame.time.set_timer(change_hole_event, 650)
			flag = True

		# 第二關
		elif time_remain == 80 and not flag:
			hole_pos = random.choice(cfg.HOLE_POSITIONS)
			mole.reset()
			mole.setPosition(hole_pos)
			pygame.time.set_timer(change_hole_event, 600)
			flag = True
		# 第三關
		elif time_remain == 60 and not flag:
			hole_pos = random.choice(cfg.HOLE_POSITIONS)
			mole.reset()
			mole.setPosition(hole_pos)
			pygame.time.set_timer(change_hole_event, 550)
			flag = True

		# 第四關
		elif time_remain == 40 and not flag:
			hole_pos = random.choice(cfg.HOLE_POSITIONS)
			mole.reset()
			mole.setPosition(hole_pos)
			pygame.time.set_timer(change_hole_event, 500)
			flag = True

		# 第五關
		elif time_remain == 20 and flag:
			hole_pos = random.choice(cfg.HOLE_POSITIONS)
			mole.reset()
			mole.setPosition(hole_pos)
			pygame.time.set_timer(change_hole_event, 450)
			flag = False
		# 關卡顯示
		if time_remain == 100:
			number = 1
		elif time_remain == 80:
			number = 2
		elif time_remain == 60:
			number = 3
		elif time_remain == 40:
			number = 4
		elif time_remain == 20:
			number = 5

4.1.13倒計時音效

if time_remain == 10:
			audios['count_down'].play()

4.1.14遊戲結束

if time_remain < 0:
			break
		count_down_text = font.render('Time: '+str(time_remain), True, cfg.WHITE)

4.1.15按鍵檢測

for event in pygame.event.get():
			if event.type == pygame.QUIT:
				pygame.quit()
				sys.exit()
			elif event.type == pygame.MOUSEMOTION:
				hammer.setPosition(pygame.mouse.get_pos())
			elif event.type == pygame.MOUSEBUTTONDOWN:
				if event.button == 1:
					hammer.setHammering()
			elif event.type == change_hole_event:
				hole_pos = random.choice(cfg.HOLE_POSITIONS)
				mole.reset()
				mole.setPosition(hole_pos)

4.1.16-碰撞檢測

if hammer.is_hammering and not mole.is_hammer:
			is_hammer = pygame.sprite.collide_mask(hammer, mole)
			if is_hammer:
				audios['hammering'].play()
				mole.setBeHammered()
				your_score += 10

4.1.17分數

your_score_text = font.render('Score: '+str(your_score), True, cfg.BROWN)
		your_number_text2 = font.render('第 '+str(number)+'關', True, cfg.WHITE)

4.1.18綁定必要的遊戲元素到屏幕(注意順序)

screen.blit(bg_img, (0, 0))
		screen.blit(count_down_text, (800, 8))
		screen.blit(your_score_text, (750, 430))
		screen.blit(your_number_text2, (600, 430))
		mole.draw(screen)
		hammer.draw(screen)

4.1.19讀取最佳分數

try:
		best_score = int(open(cfg.RECORD_PATH).read())
	except:
		best_score = 0

4.1.20若當前分數大於最佳分數則更新最佳分數

if your_score > best_score:
		f = open(cfg.RECORD_PATH, 'w')
		f.write(str(your_score))
		f.close()

4.1.21 結束界面

score_info = {'your_score': your_score, 'best_score': best_score}
	is_restart = endInterface(screen, cfg.GAME_END_IMAGEPATH, cfg.GAME_AGAIN_IMAGEPATHS, score_info, cfg.FONT_PATH, [cfg.WHITE, cfg.RED], cfg.SCREENSIZE)
	return is_restart
