[파이썬] pygame 으로 간단한 아케이드 게임을 만들어보자 - 팩맨

pygame으로 간단하게 팩맨을 만들어보겠습니다.

 

지도입니다. 1은 벽, 2는 동전, 3은 몬스터입니다.

map=[[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
     [1,2,2,2,2,2,2,3,2,2,2,2,2,2,2,2,2,2,2,1],
     [1,2,1,1,2,1,1,2,1,2,1,1,1,2,1,1,1,2,2,1],
     [1,2,1,1,2,1,2,2,1,2,2,2,2,2,2,2,2,2,3,1],
     [1,3,1,1,2,1,2,1,1,1,1,1,1,2,1,1,1,1,2,1],
     [1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,1],
     [1,1,1,2,1,1,1,1,1,1,1,2,1,1,1,2,1,1,2,1],
     [1,2,2,2,2,1,2,2,2,1,2,2,2,1,2,2,2,1,2,1],
     [1,2,1,1,2,2,2,1,2,3,2,1,2,2,2,1,2,2,3,1],
     [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]
     ]

drawmap 함수를 만들어 맵을 생성합니다.

def drawmap():
    y=0
    x=0
    for i in map:
        y=0
        for j in i:
            if j==1:
                Wall(y,x)
            if j==2:
                Coin(y,x)
            if j==3:
                Monster(y,x)
            y+=1
        x+=1

 

벽, 동전, 몬스터 클래스를 만들어보겠습니다.

#벽
class Wall(pygame.sprite.Sprite):
    def __init__(self,x,y):
        super().__init__()
        self.image=pygame.Surface([BLOCK_SIZE,BLOCK_SIZE])
        self.rect=self.image.get_rect()
        self.rect.x=x*BLOCK_SIZE
        self.rect.y=y*BLOCK_SIZE
        
        wall_sprites.add(self)
        all_sprites.add(self)
#코인
class Coin(pygame.sprite.Sprite):
    def __init__(self,x,y):
        super().__init__()
        radius = 2
 
        self.image = pygame.Surface([4,4], pygame.SRCALPHA)
        pygame.draw.circle(self.image, YELLOW, (radius,radius), radius)

        self.rect = self.image.get_rect()
        self.rect.x = x * BLOCK_SIZE + BLOCK_SIZE//2
        self.rect.y = y * BLOCK_SIZE + BLOCK_SIZE//2

        all_sprites.add(self)
        coin_sprites.add(self)
    def update(self):
        #플레이어와 부딪히면 삭제하고, 점수를 늘립니다
        if pygame.sprite.spritecollide(self,player_sprite,False):
            self.kill()
            global score
            score += 10
            pygame.display.set_caption("score: " + str(score))
#몬스터
class Monster(pygame.sprite.Sprite):
    def __init__(self,x,y):
        super().__init__()
        radius = 10
 
        self.image = pygame.Surface([20,20], pygame.SRCALPHA)
        pygame.draw.circle(self.image, RED, (radius,radius), radius)

        self.rect = self.image.get_rect()
        self.rect.x = x * BLOCK_SIZE + 10
        self.rect.y = y * BLOCK_SIZE + 10
        #몬스터의 이동방향
        self.direction=random.choice(directions)
      
        all_sprites.add(self)
        monster_sprites.add(self)
    def update(self):
        #몬스터의 이동방향을 가져옵니다
        dx,dy=self.direction
    	#이동합니다.
        self.rect.x += dx
        self.rect.y += dy 
        #만약 벽과 부딪히면, 다시 왔던방향으로 돌아가고, 새로운 방향을 설정합니다.
        if pygame.sprite.spritecollide(self, wall_sprites, False, pygame.sprite.collide_rect) or not 0 <= self.rect.x < WIDTH or not 0 <= self.rect.y < HEIGHT:
            self.rect.x -= dx 
            self.rect.y -= dy
            self.direction=random.choice(directions)

플레이어 클래스를 만듭니다.

 

class Pacman(pygame.sprite.Sprite):
    def __init__(self,x,y):
        super().__init__()
        radius = 10
    
        self.image = pygame.Surface([20,20], pygame.SRCALPHA)
        pygame.draw.circle(self.image, YELLOW, (radius,radius), radius)
        self.rect = self.image.get_rect()
        self.rect.x = x * BLOCK_SIZE + 10
        self.rect.y = y * BLOCK_SIZE + 10
      
        all_sprites.add(self)
        player_sprite.add(self)
    def update(self):
        keys = pygame.key.get_pressed()
        dx,dy = 0,0
        if keys[pygame.K_LEFT]:
            dx=-1
        elif keys[pygame.K_RIGHT]:
            dx=1    
        elif keys[pygame.K_UP]:
            dy=-1
        elif keys[pygame.K_DOWN]:
            dy=1
        self.rect.x+=dx
        self.rect.y+=dy
        #벽과 충돌 감지
        if pygame.sprite.spritecollide(self,wall_sprites,False,pygame.sprite.collide_rect):
           self.rect.x-=dx
           self.rect.y-=dy
        #몬스터와 충돌 감지
        if pygame.sprite.spritecollide(self,monster_sprites,False,pygame.sprite.collide_rect):
            pygame.quit()
            quit()
