Pygame不识别碰撞

Question

但我是pygame的新手，仍然在研究一些小怪癖。我有碰撞功能不再向我抛出错误，但它无法检测到碰撞？我知道它比较了左上角的点，所以这是否意味着精灵必须有相同的大小？ 我调整了对象的大小，使其保持相同的大小，但它无法适应，但我知道有一种方法可以让它移动。如有任何建议，我们将不胜感激

    #    print("yo new score is", score)
pygame.quit() #unintiliazes pygames
quit() #this will exit out of python

这是我导入的类

import pygame
import os
import time

gameDisplay= pygame.display.set_mode((800, 600))
class sprites(pygame.sprite.Sprite):
    def __init__(self, image, xcoor, ycoor):
        # Call the parent class (Sprite) constructor
        pygame.sprite.Sprite.__init__(self)
        self.image = image
        self.rect = self.image.get_rect()
        self.rectx=xcoor
        self.recty=ycoor
        self.rect.topleft = self.rectx, self.recty
    def pos(self):
        gameDisplay.blit(self.image, [self.rectx, self.recty])
    def left(self):
        dist = 7
        self.rectx = self.rectx - dist

Answer 1

pygame.sprite.collide()使用精灵的rect属性检查是否发生了冲突。您正在为每个精灵创建一个rect对象，但是正在使用另一个属性来移动和定位它们。self.rect属性在整个游戏中处于相同的位置。所以玩家和物体永远不会碰撞，除非它们从同一个位置开始，然后它们总是碰撞

使用rect的x和y来移动精灵，而不是创建新的属性self.rectx和self.recty。这可以通过点符号来访问

class Sprite(pygame.sprite.Sprite):  # Start classnames with capital letter!
    def __init__(self, image, x_coor, y_coor):
        # Call the parent class (Sprite) constructor
        pygame.sprite.Sprite.__init__()
        self.image = image
        self.rect = self.image.get_rect()
        self.rect.x = x_coor  # Notice that we're assigning to the rects x value!
        self.rect.y = y_coor  # The same here.

    def pos(self):
        gameDisplay.blit(self.image, self.rect)  # Position the sprite according to the the rect.

    def left(self):
        dist = 7
        self.rect.x = self.rect.x - dist  # Assigning to the rect's x attribute.

在程序的其余部分，您应该更改属性player.rect.x和player.rect.y，而不是player.rectx和player.recty
