Brief introduction of principle

In this issue, we implement some features that have not been implemented before, as well as do some functional optimization (part of the content for testing convenience, I will set the character to invincible state). First of all, it is the prompt effect of game events such as picking items. The core code is as follows:

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 # frame left, top = self.cfg.BLOCKSIZE / / 2,100 width Height = self.cfg.SCREENSIZE [0] / / self.cfg.BLOCKSIZE-1,2 pygame.draw.rect (screen, (1999,97,20), (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) # text 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) 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)

Effect:

That is, there are mainly three types of stores: one is an open shop that trades with gold coins to increase its health, attack and defense; one is a merchant who trades with gold coins and can obtain / sell keys of different colors; and there is a mysterious old man who trades with experience and can get hints of grade, attack and defense. The effect is as follows

Then, let's realize the special effects of some treasures that can be found in the map, including the compass of the wind, the holy emblem of light, the nut of the star god and the cross of luck.

Among them, the compass of the wind is used to jump between the floors that have been passed. The code is as follows:

Def showjumplevel (self, screen, scenes): # main loop 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) #-- key detection 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) #-dialog #-background 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) #-Border pygame.draw.rect (screen, (1999,97,20), (left-4, top-4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8) 7) #-display options for idx in list (range (self.max_map_level_pointer+1)): if selected_level = = idx: text = f '➤ layer {idx}' font_render = font.render (text, True, (255,0) 0) else: text = f 'layer {idx}' 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) #-refresh pygame.display.flip () clock.tick (self.cfg.FPS)

Effect:

Then there is the holy emblem, which is used to view the basic situation of the monster. The code is implemented as follows:

Def showforecastlevel (self, screen, scenes): # main loop 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 #-dialog #-background 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) #-Border pygame.draw.rect (screen, (1999,97,20), (left-4, top-4, self.cfg.BLOCKSIZE * width + 8, self.cfg.BLOCKSIZE * height + 8), 7) #-display option 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' name: {monster [0]} Life: {monster [1]} attack: {monster [2]} Defense: {monster [3]} Gold Coin: {monster [4]} experience: {monster [5]} loss: {self.hero.winmonster (monster) [1]} 'font_render = font.render (text, True, (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) #-Operation Tip 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 = 'Spacebar' font_render = font.render (tip_text, True, 255,255) rect.left, rect.bottom = self.cfg.BLOCKSIZE * width + 30, self.cfg.BLOCKSIZE * (height + 1) + 10 screen.blit (font_render, rect) #-Refresh pygame.display.flip () clock.tick (self.cfg.FPS)

Effect:

Then let's implement the Lucky Cross and give it to the fairy in the preface so that we can improve all our abilities (attack defense and health).

# define all conversations if self.hero.has_cross: conversations = [['fairy, I have found that cross.'], ['you have done well. So now I will begin to give you more power! Mira do Mimi beep.

On that floor,' 'The mana of all your treasures will lose its effect.] 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) this is the end of the introduction to "how to use Python scripts to achieve Motta Mini Game".
