充分使用游戏素材，展示动画特效

主要思路比较直观：

• 加载一些列游戏素材图片
• 获取鼠标点击位置
• 顺序播放一系列图片帧，获得爆炸效果

效果如下：

• 加载素材

  explosion_frames = []

   for i in range(16):
       img = pygame.image.load(f"explosion/frame{i:04}.png")
       explosion_frames.append(img)
  

• 获取鼠标位置

  # 处理鼠标点击事件

       if event.type == pygame.MOUSEBUTTONDOWN:
           mouse_x, mouse_y = event.pos
           #if button_x <= mouse_x <= button_x + button_width and button_y <= mouse_y <= button_y + button_height:
           explosion_playing = True
  

• 绘制系列图片

  if explosion_playing:

       if frame_index < len(explosion_frames):
           frame = explosion_frames[frame_index]
           game_display.blit(frame, (mouse_x, mouse_y))
           frame_index += 1
           pygame.time.wait(100)
       else:
           explosion_playing = False
           frame_index = 0
  

完整代码如下：

import pygame

pygame.init()

# 窗口尺寸
width = 800
height = 600
game_display = pygame.display.set_mode((width, height))

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
BLUE = (0, 0, 255)

# 按钮尺寸和位置
button_width = 80
button_height = 40
button_x = width // 2 - button_width // 2
button_y = height // 2 - button_height // 2

# 加载爆炸动画帧
explosion_frames = []
for i in range(16):
    img = pygame.image.load(f"explosion/frame{i:04}.png")
    explosion_frames.append(img)

# 当前动画帧索引
frame_index = 0

# 爆炸动画是否正在播放
explosion_playing = False

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

        # 处理鼠标点击事件
        if event.type == pygame.MOUSEBUTTONDOWN:
            mouse_x, mouse_y = event.pos
            #if button_x <= mouse_x <= button_x + button_width and button_y <= mouse_y <= button_y + button_height:
            explosion_playing = True

    # 绘制游戏内容
    game_display.fill(BLACK)  # 填充窗口为黑色

    # 绘制按钮
    if explosion_playing:
        if frame_index < len(explosion_frames):
            frame = explosion_frames[frame_index]
            game_display.blit(frame, (mouse_x, mouse_y))
            frame_index += 1
            pygame.time.wait(100)
        else:
            explosion_playing = False
            frame_index = 0
    else:
        pass
        #pygame.draw.rect(game_display, BLUE, (button_x, button_y, button_width, button_height), 2)

    # 更新显示
    pygame.d

isplay.update()

pygame.quit()
