Pygame沒有識別碰撞

Question

但是我對pygame很陌生，仍然在努力解決小怪癖。我有碰撞功能不會再向我拋出錯誤，但它不能檢測到碰撞？我知道它比較了左上角的點，所以這意味着精靈必須具有相同的尺寸？ 我調整了我的對象的大小，但它不會接受它，但我知道有一個確定的方法來讓它移動。任何建議，非常感謝！

，這裏是我的課，我導入

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()使用精靈rect屬性來檢查，如果有衝突發生。您正在爲每個精靈創建一個rect對象，但正在使用另一個屬性來移動和定位它們。整個遊戲中self.rect屬性處於相同位置。所以玩家和對象永遠不會碰撞，除非他們在相同的位置開始，然後他們會一直碰撞。

而不是創建新屬性self.rectx和self.recty，使用您的rect的x和y來移動精靈。這可以通過點符號來訪問。

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. 

在你的程序的其餘部分，你應該改變屬性player.rect.x和player.rect.y，而不是player.rectx和player.recty。
