パックマンのゲームを作って、衝突後のパックのペレットを取り除く方法がわからない

Question

現在、パックマンのゲームを作っていて、衝突した後にペレットをスクリーンから取り除く方法を考えています。私は色を黒に変えようとしましたが、動作させることができませんでした。私は次にdel要素のインデックスにしようとしましたが、それも動作しませんでした。

import pygame 
import os 
import sys 


#initialise the game 
pygame.init() 
screen = pygame.display.set_mode((448, 576)) 
done = False 

y = 416 
x = 232 

#sets up clock and loads pacman image 
clock = pygame.time.Clock() 
PACMANSPRITE = pygame.image.load("pacman.png").convert_alpha() 
PACMAN_MAP = pygame.image.load("pacman_map.png").convert_alpha() 

#gets pacman intro music, sets music to lower volume then plays it 
pygame.mixer.music.load('pacman_beginning.WAV') 
pygame.mixer.music.set_volume(0.01) 
pygame.mixer.music.play(0) 


#box class, used for boxes to border pacmans map 
class boxcollisions(pygame.sprite.Sprite): 
    def __init__(self, x, y): 
     self.y = y 
     self.x = x 
     self.rect = pygame.Rect(self.x, self.y, 12, 12) 
     self.colour = (0, 128, 255) 

    def draw(self, screen): 
     pygame.draw.rect(screen, self.color, self.rect) 

class pointclass(pygame.sprite.Sprite): 
    def __init__(self, x, y): 
     self.y = y 
     self.x = x 
     self.rect = pygame.Rect(self.x, self.y, 12, 12) 
     self.colour = (255, 204, 153) 
     self.score=0 

    def draw(self, screen): 
     pygame.draw.rect(screen, self.colour, self.rect) 

    def addpoint(self): 
     self.score+=1 
     print(self.score) 
     self.colour= (0,0,0) 
     print('why isnt it working')

      self.x -= 2 
     if pressed[pygame.K_RIGHT]: 
      self.x += 2 
     self.rect.left = self.x 
     self.rect.top = self.y

Answer 1

私が知っている最も簡単な方法は、（と私は多くのことを知らない）pygame.sprite.Group()とpygame.sprite.spritecollideを使用しています。

基本的なロジックは、ペレットのスプライトグループを作成し、すべてのペレットをスプライトとして作成し、グループに追加することです。ゲームループが繰り返されるたびに、スプライトグループを画面に描画し、プレイヤキャラクタとペレットグループ内のペレットのいずれかが衝突しているかどうかを確認します（spritecollide）。

spritecollideには、衝突が発生したときにペレットを除去するためのパラメータがあります。そのため、次のループで描画するのを避けるために、spritecollideをtrueに設定する必要があります。

#Basic logic as example. 

pellets = pygame.sprite.Group() 
#CREATE PELLETS AND ADD THEM TO THE pellets sprite group. 

player = Sprite() 

... 

#IN THE GAME LOOP 

    #Validate if there was a collision. 
    pellets_hit = pygame.sprite.spritecollide(player, pellets, True) #True indicates that, if there were any hit, remove the pellet from the group. 

    if len(pellet_hit): 
     #Increment score or something. 

    ... 

    #Updating the display 
    player.draw(screen) 
    pellets.draw(screen) #If there were any hit, the pellet won't be in this group and won't be drawn 

これはスプライトとスプライトグループを使用するプロジェクトの例です：

Answer 2

私は基本的に仕事

#spawn pellets function 
def spawnpellets(pointspawns): 
    abc=0 
    efg=0 
    px=0 
    py=-16 
    for row in pointspawns: 
     #y co ordinate 
     py=py+16  
     for n in row: 
      #x co ordinate 
      n=n-1 
      px=n*16 
      point=(pointclass(px, py)) 
      #used to draw points 
      point.draw(screen) 
      if pygame.sprite.collide_rect(sprite, point): 
       tempfunc(pointspawns, row, n , py) 

def tempfunc(pointspawns, row, n, py): 
    abc=n+1 
    efg=py/16 
    efg=int(efg) 
    tempindex=row.index(abc) 
    del pointspawns[efg][tempindex] 
    pointspawns[int(efg)].insert(abc,0) 

多くの後、私はの産卵を入れていたことを考え出しましたペレットを関数にしてから、別の関数として衝突検出を行い、forループでvaulesやrowとnを使って、正確なリストとインデックスを探し出しました。次に、要素を0に置き換えます後書きする必要はありません再。私の変数名はひどいですが、文字通りちょうど2時間後にこれを終了しましたので、今すぐに値する休憩をとります。
