这篇文章给大家介绍pygame实现俄罗斯方块游戏，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
在Panel类里增加函数
def check_overlap(self, diffx, diffy): for x,y in self.moving_block.get_rect_arr(): for rx,ry in self.rect_arr: if x+diffx==rx and y+diffy==ry: return True return False
修改move_block函数的判断，增加check_overlap函数检测
def move_block(self): if self.moving_block is None: create_move_block() if self.moving_block.can_move(0,1) and not self.check_overlap(0,1): self.moving_block.move(0,1) else: self.add_block(self.moving_block) self.create_move_block()
现在的效果是方块可以堆叠了
六、键盘控制左右移动
导入变量
from pygame.locals import KEYDOWN,K_LEFT,K_RIGHT,K_UP,K_DOWN
Panel类里增加一个控制移动方块的函数
def control_block(self, diffx, diffy): if self.moving_block.can_move(diffx,diffy) and not self.check_overlap(diffx, diffy): self.moving_block.move(diffx,diffy)
鼠标事件监听处做下键盘的响应
if event.type == KEYDOWN: if event.key == K_LEFT: main_panel.control_block(-1,0) if event.key == K_RIGHT: main_panel.control_block(1,0) if event.key == K_UP: pass # 变形过会实现 if event.key == K_DOWN: main_panel.control_block(0,1)
由于Block类的can_move函数没有实现左右移动的判断，所以需要再对can_move
增加左右边界的处理
def can_move(self,xdiff,ydiff): for x,y in self.rect_arr: if y+ydiff>=20: return False if x+xdiff<0 or x+xdiff>=10: return False return True
现在，左右的移动也正常了，效果图如下

screencaption = pygame.display.set_caption('Tetris')
screen = pygame.display.set_mode((main_panel_width+160+space*3,main_panel_height+space*2)) #设置窗口长宽
main_panel=Panel(screen,main_block_size,[space,space,main_panel_width,main_panel_height])
pygame.key.set_repeat(200, 30)
main_panel.create_move_block()
diff_ticks = 300 # 移动一次蛇头的事件，单位毫秒
ticks = pygame.time.get_ticks() + diff_ticks
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
if event.type == KEYDOWN:
if event.key == K_LEFT: main_panel.control_block(-1,0)
if event.key == K_RIGHT: main_panel.control_block(1,0)
if event.key == K_UP: pass # 变形过会实现
if event.key == K_DOWN: main_panel.control_block(0,1)
screen.fill((100,100,100)) # 将界面设置为灰色
main_panel.paint() # 主面盘绘制
pygame.display.update() # 必须调用update才能看到绘图显示
if pygame.time.get_ticks() >= ticks:
ticks+=diff_ticks
main_panel.move_block()
run()七、控制变形
变形的实现，我们对每个方块子类的初始化函数稍作修改，将获取形状做一个独立的get_shape函数，并且给每个子类增加一个变量用于记录当前形态id，用一个变量用于标识每种方块的形态数量，以T型为例，修改后代码如下
class TBlock(Block): # 四种形态 shape_id=0 shape_num=4 def __init__(self, n=None): super(TBlock, self).__init__() if n is None: n=random.randint(0,3) self.shape_id=n self.rect_arr=self.get_shape() def get_shape(self): if self.shape_id==0: return [(0,1),(1,1),(2,1),(1,2)] elif self.shape_id==1: return [(1,0),(1,1),(1,2),(0,1)] elif self.shape_id==2: return [(0,1),(1,1),(2,1),(1,0)] else: return [(1,0),(1,1),(1,2),(2,1)]
这样我们在Block父类里可以加一个change函数，用于变换至下一形态，由于变化时要保持原来的移动位置，我们增加sx，sy两个变量将方块移动过的位置存着，便于在变化时使用
class Block(object): sx=0 sy=0 def __init__(self): self.rect_arr=[] def get_rect_arr(self): # 用于获取方块种的四个矩形列表 return self.rect_arr def move(self,xdiff,ydiff): # 用于移动方块的方法 self.sx+=xdiff self.sy+=ydiff self.new_rect_arr=[] for x,y in self.rect_arr: self.new_rect_arr.append((x+xdiff,y+ydiff)) self.rect_arr=self.new_rect_arr def can_move(self,xdiff,ydiff): for x,y in self.rect_arr: if y+ydiff>=20: return False if x+xdiff<0 or x+xdiff>=10: return False return True def change(self): self.shape_id+=1 # 下一形态 if self.shape_id >= self.shape_num: self.shape_id=0 arr = self.get_shape() new_arr = [] for x,y in arr: if x+self.sx<0 or x+self.sx>=10: # 变形不能超出左右边界 self.shape_id -= 1 if self.shape_id < 0: self.shape_id = self.shape_num - 1 return None new_arr.append([x+self.sx,y+self.sy]) return new_arr
在Panel类里的再增加一个change函数，直接调用moving_block的change
def change_block(self): if self.moving_block: new_arr = self.moving_block.change() if new_arr and not self.check_overlap(0, 0, check_arr=new_arr): # 变形不能造成方块重叠 self.moving_block.rect_arr=new_arr
最后将key_up事件的响应加入change_block的调用就好了
if event.key == K_UP: main_panel.change_block()
现在已经实现了，变形和移动了，方块基本可以正常下落了
八、方块的消除
这个计算主要是处理Panel类的rect_arr，如果数组中出现某一行有10个就符合消除条件，为简化计算，我们将这些矩形按y值存到一个数组中，便于计算
def check_clear(self): tmp_arr = [[] for i in range(20)] # 先将方块按行存入数组 for x,y in self.rect_arr: if y<0: return tmp_arr[y].append([x,y]) clear_num=0 clear_lines=set([]) y_clear_diff_arr=[[] for i in range(20)] # 从下往上计算可以消除的行，并记录消除行后其他行的向下偏移数量 for y in range(19,-1,-1): if len(tmp_arr[y])==10: clear_lines.add(y) clear_num += 1 y_clear_diff_arr[y] = clear_num if clear_num>0: new_arr=[] # 跳过移除行，并将其他行做偏移 for y in range(19,-1,-1): if y in clear_lines: continue tmp_row = tmp_arr[y] y_clear_diff=y_clear_diff_arr[y] for x,y in tmp_row: new_arr.append([x,y+y_clear_diff]) self.rect_arr = new_arr
在Panel的move_block处增加check_clear的调用
def move_block(self): if self.moving_block is None: create_move_block() if self.moving_block.can_move(0,1) and not self.check_overlap(0,1): self.moving_block.move(0,1) else: self.add_block(self.moving_block) self.check_clear() self.create_move_block()
现在游戏可以消除方块了
九、增加空格键使快速落下
快速落下可以快速调用Panel的move_block函数，我们在move_block函数增加一个返回值，用于标记使正常下移还是移到底部后新的方块
def move_block(self): if self.moving_block is None: create_move_block() if self.moving_block.can_move(0,1) and not self.check_overlap(0,1): self.moving_block.move(0,1) return 1 else: self.add_block(self.moving_block) self.check_clear() self.create_move_block() return 2
在键盘响应处增加键盘处理
if event.key == K_SPACE: while main_panel.move_block()==1: pass
十、增加游戏结束判断
游戏结束同样可以在Panel类的move_block中处理，如果一个方块到底，并且消除进行后，发现有方块的y值小于0，那么一定是失败了
修改Panel类的move_block函数
def move_block(self): if self.moving_block is None: create_move_block() if self.moving_block.can_move(0,1) and not self.check_overlap(0,1): self.moving_block.move(0,1) return 1 else: self.add_block(self.moving_block) self.check_clear() for x,y in self.rect_arr: if y<0: return 9 # 游戏失败 self.create_move_block() return 2
增加一个变量记录游戏状态
game_state = 1 # 游戏状态1.表示正常 2.表示失败
计时器处修改程序
if game_state == 1 and pygame.time.get_ticks() >= ticks: ticks+=diff_ticks if main_panel.move_block()==9: game_state = 2
鼠标键盘响应空格键中也增加一下判断
if event.key == K_SPACE: flag = main_panel.move_block() while flag==1: flag = main_panel.move_block() if flag == 9: game_state = 2
最后增加游戏结束文字的绘制
if game_state == 2:
myfont = pygame.font.Font(None,30)
white = 255,255,255
textImage = myfont.render("Game over", True, white)
screen.blit(textImage, (160,190))好了，现在会提示游戏结束了
