pygame實(shí)現(xiàn)俄羅斯方塊游戲（基礎(chǔ)篇3）

更新時(shí)間：2019年10月29日 14:24:49 作者：冰風(fēng)漫天

這篇文章主要介紹了pygame實(shí)現(xiàn)俄羅斯方塊游戲基礎(chǔ)的第3篇，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

上一章請(qǐng)點(diǎn)擊查看：pygame實(shí)現(xiàn)俄羅斯方塊游戲（基礎(chǔ)篇2）

現(xiàn)在繼續(xù)

一、給每個(gè)方塊設(shè)置不同的顏色

根據(jù)代碼這里可以判斷正在下落的方塊在那些Block子類里加一個(gè)屬性最合適，而已經(jīng)落下的方塊顏色管理最合適的地方應(yīng)該是修改在Panel類里的rect_arr
Block子類里的修改比較簡(jiǎn)單，以TBlock類為例，在__init__函數(shù)加一行

self.color=(255,0,0)

在Panel的paint函數(shù)里將代碼

# 繪制正在落下的方塊
 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)

已經(jīng)下落的方塊修改會(huì)麻煩一點(diǎn)，原來存在rect_arr里的是x,y，現(xiàn)在要增加一個(gè)顏色，直接改也是可以的，不過考慮到以后的擴(kuò)展性，果斷定義一個(gè)RectInfo類

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

將存入rect_arr時(shí)的代碼修改為

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

并將設(shè)計(jì)rect_arr做下修改即可

 if game_state == 1 and pygame.time.get_ticks() >= ticks:

 if main_panel.move_block()==9: game_state = 2 # 游戲結(jié)束

run()

二、下一個(gè)方塊

為便于下一方塊的提示窗的繪制，我們定義一個(gè)類HintBox，用于管理下一方塊和界面的繪制

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: # 如果還沒有方塊，先產(chǎn)生一個(gè)
 block = create_block()
 
 self.next_block = create_block() # 產(chǎn)生下一個(gè)方塊
 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
 # 繪制正在落下的方塊
 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
 # 計(jì)算使方塊繪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類里面增加一個(gè)屬性

hint_box=None

將Panel類里面的

def create_move_block(self):
 block = create_block()
 block.move(5-2,-2) # 方塊挪到中間 
 self.moving_block=block

產(chǎn)生方塊的方式，改為由hint_box產(chǎn)生

def create_move_block(self):
 block = self.hint_box.take_block()
 block.move(5-2,-2) # 方塊挪到中間 
 self.moving_block=block

在run函數(shù)里增加初始化hint_box和設(shè)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

在游戲主循環(huán)增加下一方塊提示窗的繪制

hint_box.paint() # 繪制下一個(gè)方塊的提示窗

現(xiàn)在可以正常顯示下一方塊提示了

三、分?jǐn)?shù)的計(jì)算

消除分?jǐn)?shù)的計(jì)算方式為
1行 100分
2行 300分
3行 800分
4行 1600分
類似下一方塊提示窗的設(shè)計(jì)，我們可以增加一個(gè)ScoreBox類

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屬性

score_box=None

定義一個(gè)全局的SCORE_MAP

SCORE_MAP=(100,300,800,1600)

在check_clear函數(shù)中，如果有方塊消除，則執(zhí)行

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

在run主函數(shù)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

并在游戲循環(huán)繪制score_box

score_box.paint() # 繪制總分

四、歷史最高分

準(zhǔn)備在當(dāng)前目錄用一個(gè)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在繪制當(dāng)前分?jǐn)?shù)時(shí)一起繪制，所以直接在ScoreBox增加一個(gè)最高分的屬性和一個(gè)文件的定義

high_score = 0
db_file = 'tetris.db'

在ScoreBox的初始化函數(shù)里增加pickle的加載

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

在paint里增加下最高分的繪制

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))

將之前直接對(duì)ScoreBox的score的修改改為封裝一個(gè)add_score的函數(shù)

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函數(shù)里進(jìn)行score的修改并做是否超過最高分的判斷，如果超過則保存分?jǐn)?shù)（當(dāng)然也可以在游戲結(jié)束或關(guān)閉界面時(shí)判斷和保存最高分，減少磁盤io）

也許有人會(huì)想右下角空那么大一塊是做什么用的？
那塊區(qū)域我是準(zhǔn)備做對(duì)戰(zhàn)顯示用的，這里基礎(chǔ)篇差不多算收尾了，下一篇準(zhǔn)備寫AI篇。
