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

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）
