Python魔塔游戏

Cooci 人气:0

前言

这一期我们继续完善我们的魔塔小游戏。

废话不多说,让我们愉快地开始吧~

开发工具

Python版本: 3.7.4

相关模块:

cpgames模块;

以及一些python自带的模块。

环境搭建

安装Python并添加到环境变量,pip安装需要的相关模块即可。

原理简介

本期我们实现一些之前还没实现的功能,以及做一些功能优化(部分内容为了测试方便,我会把人物设置成无敌状态)。首先,是拾取物品等游戏事件的提示效果,核心代码如下:

'''游戏事件提示'''
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
    # 画框
    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:

'''显示商店'''

即,商店主要包括三种类型:一种的明面上的商店,用金币进行交易,可以获得生命值、攻击力和防御力的提升;一种是商人,用金币进行交易,可以获得/出售不同颜色的钥匙;还有一种是神秘老人,用经验值进行交易,可以获得等级、攻击力和防御力的提示。效果如下

接着,我们来实现一下地图中可以捡到的一些宝物的特效,主要包括风之罗盘、圣光徽、星光神榔和幸运十字架。

其中,风之罗盘用于在已经走过的楼层间进行跳跃,代码实现如下:

'''显示关卡跳转'''
def showjumplevel(self, screen, scenes):
    # 主循环
    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)
        # --按键检测
        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)
        # --对话框
        # ----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))
        # ----边框
        pygame.draw.rect(screen, (199, 97, 20), (left - 4, top - 4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7)
        # ----展示选项
        for idx in list(range(self.max_map_level_pointer+1)):
            if selected_level == idx:
                text = f'➤第 {idx} 层'
                font_render = font.render(text, True, (255, 0, 0))
            else:
                text = f'    第 {idx} 层'
                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:

然后是圣光徽,用于查看怪物的基本情况,代码实现如下:

'''显示关卡怪物信息'''
def showforecastlevel(self, screen, scenes):
    # 主循环
    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)
        # --按键检测
        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
        # --对话框
        # ----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))
        # ----边框
        pygame.draw.rect(screen, (199, 97, 20), (left - 4, top - 4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7)
        # ----展示选项
        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'名称: {monster[0]}  生命: {monster[1]}  攻击: {monster[2]}  防御: {monster[3]}  金币: {monster[4]}  经验: {monster[5]}  损失: {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 = '空格键'
            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:

然后我们来实现一下幸运十字架,把它交给序章中的仙子,可以将自身的所有能力提升一些(攻击防御和生命值)。

# 定义所有对话
if self.hero.has_cross:
    conversations = [
        ['仙子, 我已经将那个十字架找到了.'],
        ['你做得很好. 那么现在我就开始', '授予你更强的力量! 咪啦哆咪哔...', '好了, 我已经将你现在的能力提升了!', '记住: 如果你没有足够的实力的话,', '不要去第二十一层. 在那一层里,', '你所有宝物的法力都会失去作用.']
    ]
    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)
