现在继续

一、给每个方块设置不同的颜色

根据代码这里可以判断正在下落的方块在那些Block子类里加一个属性最合适,而已经落下的方块颜色管理最合适的地方应该是修改在Panel类里的rect_arr
Block子类里的修改比较简单,以TBlock类为例,在__init__函数加一行

self.color=(255,0,0)

在Panel的paint函数里将代码

# 绘制正在落下的方块
 if self.move_block:
 for rect in self.moving_block.get_rect_arr():
 x,y=rect
 pygame.draw.line(self._bg,[0,0,255],[self._x+x*bz+bz/2,self._y+y*bz],[self._x+x*bz+bz/2,self._y+(y+1)*bz],bz)
 pygame.draw.rect(self._bg,[255,255,255],[self._x+x*bz,self._y+y*bz,bz+1,bz+1],1)

中的

pygame.draw.line(self._bg,[0,0,255],[self._x+x*bz+bz/2,self._y+y*bz],[self._x+x*bz+bz/2,self._y+(y+1)*bz],bz)

改成

pygame.draw.line(self._bg,self.moving_block.color,[self._x+x*bz+bz/2,self._y+y*bz],[self._x+x*bz+bz/2,self._y+(y+1)*bz],bz)

已经下落的方块修改会麻烦一点,原来存在rect_arr里的是x,y,现在要增加一个颜色,直接改也是可以的,不过考虑到以后的扩展性,果断定义一个RectInfo类

class RectInfo(object):
 def __init__(self, x, y, color):
 self.x = x
 self.y = y
 self.color = color

将存入rect_arr时的代码修改为

def add_block(self,block):
 for x,y in block.get_rect_arr():
 self.rect_arr.append(RectInfo(x,y, block.color))

并将设计rect_arr做下修改即可

二、下一个方块

为便于下一方块的提示窗的绘制,我们定义一个类HintBox,用于管理下一方块和界面的绘制

class HintBox(object):
 next_block=None
 def __init__(self, bg, block_size, position):
 self._bg=bg;
 self._x,self._y,self._width,self._height=position
 self._block_size=block_size
 self._bgcolor=[0,0,0]

 def take_block(self):
 block = self.next_block
 if block is None: # 如果还没有方块,先产生一个
 block = create_block()
 
 self.next_block = create_block() # 产生下一个方块
 return block

 def paint(self):
 mid_x=self._x+self._width/2
 pygame.draw.line(self._bg,self._bgcolor,[mid_x,self._y],[mid_x,self._y+self._height],self._width) 
 bz=self._block_size
 # 绘制正在落下的方块
 if self.next_block:
 arr = self.next_block.get_rect_arr()
 minx,miny=arr[0]
 maxx,maxy=arr[0]
 for x,y in arr:
 if x<minx: minx=x
 if x>maxx: maxx=x
 if y<miny: miny=y
 if y>maxy: maxy=y
 w=(maxx-minx)*bz
 h=(maxy-miny)*bz
 # 计算使方块绘制在提示窗中心位置所需要的偏移像素
 cx=self._width/2-w/2-minx*bz-bz/2 
 cy=self._height/2-h/2-miny*bz-bz/2

 for rect in arr:
 x,y=rect
 pygame.draw.line(self._bg,self.next_block.color,[self._x+x*bz+cx+bz/2,self._y+cy+y*bz],[self._x+x*bz+cx+bz/2,self._y+cy+(y+1)*bz],bz)
 pygame.draw.rect(self._bg,[255,255,255],[self._x+x*bz+cx,self._y+y*bz+cy,bz+1,bz+1],1)

在Panel类里面增加一个属性

hint_box=None

将Panel类里面的

def create_move_block(self):
 block = create_block()
 block.move(5-2,-2) # 方块挪到中间 
 self.moving_block=block

产生方块的方式,改为由hint_box产生

def create_move_block(self):
 block = self.hint_box.take_block()
 block.move(5-2,-2) # 方块挪到中间 
 self.moving_block=block

在run函数里增加初始化hint_box和设置main_panel的程序

hint_box=HintBox(screen,main_block_size,[main_panel_width+space+space,space,160,160])
main_panel.hint_box=hint_box

在游戏主循环增加下一方块提示窗的绘制

hint_box.paint() # 绘制下一个方块的提示窗

现在可以正常显示下一方块提示了

pygame实现俄罗斯方块游戏(基础篇3)

三、分数的计算

消除分数的计算方式为
1行 100分
2行 300分
3行 800分
4行 1600分
类似下一方块提示窗的设计,我们可以增加一个ScoreBox类

class ScoreBox(object):
 total_score = 0
 def __init__(self, bg, block_size, position):
 self._bg=bg;
 self._x,self._y,self._width,self._height=position
 self._block_size=block_size
 self._bgcolor=[0,0,0]

 def paint(self):
 myfont = pygame.font.Font(None,36)
 white = 255,255,255
 textImage = myfont.render('Score:%06d'%(self.total_score), True, white)
 self._bg.blit(textImage, (self._x,self._y))

然后在Panel增加score_box属性

score_box=None

定义一个全局的SCORE_MAP

SCORE_MAP=(100,300,800,1600)

在check_clear函数中,如果有方块消除,则执行

score = SCORE_MAP[clear_num-1]
self.score_box.total_score += score

在run主函数初始化score_box

score_box=ScoreBox(screen,main_block_size,[main_panel_width+space+space,160+space*2,160,160])
main_panel.score_box=score_box

并在游戏循环绘制score_box

score_box.paint() # 绘制总分

pygame实现俄罗斯方块游戏(基础篇3)

四、历史最高分

准备在当前目录用一个tetris.db的pickle文件保存

所以首先

import pickle,os

由于最高分可以借用ScoreBox在绘制当前分数时一起绘制,所以直接在ScoreBox增加一个最高分的属性和一个文件的定义

high_score = 0
db_file = 'tetris.db'

在ScoreBox的初始化函数里增加pickle的加载

if os.path.exists(self.db_file): self.high_score = pickle.load(open(self.db_file,'rb'))

在paint里增加下最高分的绘制

def paint(self):
 myfont = pygame.font.Font(None,36)
 white = 255,255,255
 textImage = myfont.render('High: %06d'%(self.high_score), True, white)
 self._bg.blit(textImage, (self._x,self._y))
 textImage = myfont.render('Score:%06d'%(self.total_score), True, white)
 self._bg.blit(textImage, (self._x,self._y+40))

将之前直接对ScoreBox的score的修改改为封装一个add_score的函数

def add_score(self, score):
 self.total_score += score
 if self.total_score > self.high_score:
 self.high_score=self.total_score
 pickle.dump(self.high_score, open(self.db_file,'wb+'))

在add_score函数里进行score的修改并做是否超过最高分的判断,如果超过则保存分数(当然也可以在游戏结束或关闭界面时判断和保存最高分,减少磁盘io)

也许有人会想右下角空那么大一块是做什么用的?
那块区域我是准备做对战显示用的,这里基础篇差不多算收尾了,下一篇准备写AI篇。

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
