我目前正在制作一个吃 bean 人游戏,正在努力弄清楚如何在与屏幕碰撞后将其从屏幕上移除。我尝试将颜色更改为黑色,但无法成功。接下来我尝试删除元素索引,但这也不起作用。

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')

#pacmans class

self.currenty=self.y

def outofbounds(self):

#main game loop

pygame.display.flip()
clock.tick(60)

最佳答案

我知道的最简单的方法(我知道的不多)是使用 pygame.sprite.Group()pygame.sprite.spritecollide .

这里的基本逻辑是,为颗粒创建一个 Sprite 组,将每个颗粒创建为 Sprite 并将其添加到组中。在游戏循环的每次迭代中,将 Sprite 组绘制到屏幕上,并使用spritecollide验证玩家角色与颗粒组中的任何颗粒之间是否存在碰撞。 .

spritecollide 有一个参数可以在发生碰撞时消除颗粒,因此您需要将其设置为 true,以避免在下一个循环中绘制它。

#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

这是一个使用 Sprite 和 Sprite 组的项目示例: Snake game
