Python遊戲開發之魔塔小遊戲的實現
前言
這一期我們繼續完善我們的魔塔小遊戲。
廢話不多說，讓我們愉快地開始吧~
開發工具
Python版本： 3.7.4
相關模塊：
cpgames模塊；
以及一些python自帶的模塊。
環境搭建
安裝Python並添加到環境變量，pip安裝需要的相關模塊即可。
原理簡介
本期我們實現一些之前還沒實現的功能，以及做一些功能優化(部分內容為瞭測試方便，我會把人物設置成無敵狀態)。首先，是拾取物品等遊戲事件的提示效果，核心代碼如下：
'''遊戲事件提示'''
def showinfo(self, screen):
if self.obtain_tips is None: return
self.show_obtain_tips_count += 1
if self.show_obtain_tips_count > self.max_obtain_tips_count:
self.show_obtain_tips_count = 0
self.obtain_tips = None
# 畫框
left, top = self.cfg.BLOCKSIZE // 2, 100
width, height = self.cfg.SCREENSIZE[0] // self.cfg.BLOCKSIZE - 1, 2
pygame.draw.rect(screen, (199, 97, 20), (left - 4, top - 4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7)
for col in range(width):
for row in range(height):
image = self.resource_loader.images['mapelements']['0'][0]
image = pygame.transform.scale(image, (self.cfg.BLOCKSIZE, self.cfg.BLOCKSIZE))
screen.blit(image, (left + col * self.cfg.BLOCKSIZE, top + row * self.cfg.BLOCKSIZE))
# 文字
if isinstance(self.obtain_tips, list):
assert len(self.obtain_tips) == 2
font = pygame.font.Font(self.fontpath, 30)
font_render1 = font.render(self.obtain_tips[0], True, (255, 255, 255))
font_render2 = font.render(self.obtain_tips[1], True, (255, 255, 255))
rect1 = font_render1.get_rect()
rect2 = font_render2.get_rect()
rect1.midtop = left + width * self.cfg.BLOCKSIZE // 2, top + 10
rect2.midtop = left + width * self.cfg.BLOCKSIZE // 2, top + 10 + self.blocksize
screen.blit(font_render1, rect1)
screen.blit(font_render2, rect2)
else:
font = pygame.font.Font(self.fontpath, 40)
font_render = font.render(self.obtain_tips, True, (255, 255, 255))
rect = font_render.get_rect()
rect.midtop = left + width * self.cfg.BLOCKSIZE // 2, top + height * self.cfg.BLOCKSIZE // 2 - 20
screen.blit(font_render, rect)
效果:
'''顯示商店'''

即，商店主要包括三種類型：一種的明面上的商店，用金幣進行交易，可以獲得生命值、攻擊力和防禦力的提升；一種是商人，用金幣進行交易，可以獲得/出售不同顏色的鑰匙；還有一種是神秘老人，用經驗值進行交易，可以獲得等級、攻擊力和防禦力的提示。效果如下
接著，我們來實現一下地圖中可以撿到的一些寶物的特效，主要包括風之羅盤、聖光徽、星光神榔和幸運十字架。
其中，風之羅盤用於在已經走過的樓層間進行跳躍，代碼實現如下：
'''顯示關卡跳轉'''
def showjumplevel(self, screen, scenes):
# 主循環
clock, selected_level = pygame.time.Clock(), 1
font = pygame.font.Font(self.cfg.FONT_PATHS_NOPRELOAD_DICT['font_cn'], 20)
while True:
screen.fill((0, 0, 0))
screen.blit(self.background_images['gamebg'], (0, 0))
self.map_parser.draw(screen)
for scene in scenes:
screen.blit(scene[0], scene[1])
self.hero.draw(screen)
# --按鍵檢測
for event in pygame.event.get():
if event.type == pygame.QUIT:
QuitGame()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
return selected_level
elif event.key == pygame.K_w or event.key == pygame.K_UP:
selected_level = max(selected_level - 1, 0)
elif event.key == pygame.K_s or event.key == pygame.K_DOWN:
selected_level = min(selected_level + 1, self.max_map_level_pointer)
# --對話框
# ----底色
width, height = 11, 4
left, top = self.cfg.SCREENSIZE[0] // 2 - width // 2 * self.cfg.BLOCKSIZE, self.cfg.SCREENSIZE[1] // 2 - height * self.cfg.BLOCKSIZE
for col in range(width):
for row in range(height):
image = self.resource_loader.images['mapelements']['0'][0]
image = pygame.transform.scale(image, (self.cfg.BLOCKSIZE, self.cfg.BLOCKSIZE))
screen.blit(image, (left + col * self.cfg.BLOCKSIZE, top + row * self.cfg.BLOCKSIZE))
# ----邊框
pygame.draw.rect(screen, (199, 97, 20), (left - 4, top - 4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7)
# ----展示選項
for idx in list(range(self.max_map_level_pointer+1)):
if selected_level == idx:
text = f'➤第 {idx} 層'
font_render = font.render(text, True, (255, 0, 0))
else:
text = f' 第 {idx} 層'
font_render = font.render(text, True, (255, 255, 255))
rect = font_render.get_rect()
rect.left, rect.top = left + 20 + idx // 6 * self.cfg.BLOCKSIZE * 2, top + 20 + (idx % 6) * 30
screen.blit(font_render, rect)
# --刷新
pygame.display.flip()
clock.tick(self.cfg.FPS)
效果：
然後是聖光徽，用於查看怪物的基本情況，代碼實現如下：
'''顯示關卡怪物信息'''
def showforecastlevel(self, screen, scenes):
# 主循環
clock = pygame.time.Clock()
font = pygame.font.Font(self.cfg.FONT_PATHS_NOPRELOAD_DICT['font_cn'], 20)
monsters = self.map_parser.getallmonsters()
if len(monsters) < 1: return
monsters_show_pointer, max_monsters_show_pointer = 1, round(len(monsters) / 4)
show_tip_text, show_tip_text_count, max_show_tip_text_count = True, 1, 15
return_flag = False
while True:
screen.fill((0, 0, 0))
screen.blit(self.background_images['gamebg'], (0, 0))
self.map_parser.draw(screen)
for scene in scenes:
screen.blit(scene[0], scene[1])
self.hero.draw(screen)
# --按鍵檢測
for event in pygame.event.get():
if event.type == pygame.QUIT:
QuitGame()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_l:
return_flag = True
elif event.key == pygame.K_SPACE:
monsters_show_pointer = monsters_show_pointer + 1
if monsters_show_pointer > max_monsters_show_pointer: monsters_show_pointer = 1
elif event.type == pygame.KEYUP:
if event.key == pygame.K_l and return_flag:
return
# --對話框
# ----底色
width, height = 14, 5
left, top = self.cfg.SCREENSIZE[0] // 2 - width // 2 * self.cfg.BLOCKSIZE, self.cfg.SCREENSIZE[1] // 2 - height * self.cfg.BLOCKSIZE
for col in range(width):
for row in range(height):
image = self.resource_loader.images['mapelements']['0'][0]
image = pygame.transform.scale(image, (self.cfg.BLOCKSIZE, self.cfg.BLOCKSIZE))
screen.blit(image, (left + col * self.cfg.BLOCKSIZE, top + row * self.cfg.BLOCKSIZE))
# ----邊框
pygame.draw.rect(screen, (199, 97, 20), (left - 4, top - 4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7)
# ----展示選項
for idx, monster in enumerate(monsters[(monsters_show_pointer-1)*4: monsters_show_pointer*4]):
id_image = self.resource_loader.images['mapelements'][monster[6]][0]
id_image = pygame.transform.scale(id_image, (self.cfg.BLOCKSIZE - 10, self.cfg.BLOCKSIZE - 10))
screen.blit(id_image, (left + 10, top + 20 + idx * self.cfg.BLOCKSIZE))
text = f'名稱: {monster[0]} 生命: {monster[1]} 攻擊: {monster[2]} 防禦: {monster[3]} 金幣: {monster[4]} 經驗: {monster[5]} 損失: {self.hero.winmonster(monster)[1]}'
font_render = font.render(text, True, (255, 255, 255))
rect = font_render.get_rect()
rect.left, rect.top = left + 15 + self.cfg.BLOCKSIZE, top + 30 + idx * self.cfg.BLOCKSIZE
screen.blit(font_render, rect)
# ----操作提示
show_tip_text_count += 1
if show_tip_text_count == max_show_tip_text_count:
show_tip_text_count = 1
show_tip_text = not show_tip_text
if show_tip_text:
tip_text = '空格鍵'
font_render = font.render(tip_text, True, (255, 255, 255))
rect.left, rect.bottom = self.cfg.BLOCKSIZE * width + 30, self.cfg.BLOCKSIZE * (height + 1) + 10
screen.blit(font_render, rect)
# --刷新
pygame.display.flip()
clock.tick(self.cfg.FPS)
效果：
然後我們來實現一下幸運十字架，把它交給序章中的仙子，可以將自身的所有能力提升一些(攻擊防禦和生命值)。
# 定義所有對話
if self.hero.has_cross:
conversations = [
['仙子, 我已經將那個十字架找到瞭.'],
['你做得很好. 那麼現在我就開始', '授予你更強的力量! 咪啦哆咪嗶...', '好瞭, 我已經將你現在的能力提升瞭!', '記住: 如果你沒有足夠的實力的話,', '不要去第二十一層. 在那一層裡,', '你所有寶物的法力都會失去作用.']
]
self.hero.has_cross = False
self.hero.life_value = int(self.hero.life_value * 4 / 3)
self.hero.attack_power = int(self.hero.attack_power * 4 / 3)
self.hero.defense_power = int(self.hero.defense_power * 4 / 3)
