Pygame 使用 colliderect 时关闭

Question

我正在努力做到当主角(mc)被蜘蛛触动时，pygame closes.I对pygame.Rect的理解不是很深，但这不应该起作用吗？无论如何，pygame 在添加此代码后关闭：

mcrect = mc.get_rect()
spirect = spider_small.get_rect()

if mcrect.colliderect(spirect):
    pygame.quit()
    sys.exit()

完整代码供参考：

import pygame

import time
import math





#Initializing stuff and setting display settings
wait = time.sleep

print("What is your preferred screen width and height?(800,600 or greater.)")
wait(1)
print("If your chosen resolution is below 800,600 , you will be automatically set to 800,600")
wait(1)


preferred_screen_width = raw_input("Width?")
print("Dank MLG processing...")
wait(1.5)
preferred_screen_height = raw_input("Height?")
print("More dank MLG processing...")
wait(1.5)


pygame.init()

Answer 1

当您使用 Surface 的 get_rect() 功能创建 Rect 时，Rect 的 topleft 属性将始终成为 0, 0.

由于您永远不会更改 mcrect 和 spirect，因此它们总是重叠，因为它们的位置相同 (0, 0)；所以 mcrect.colliderect(spirect) 将永远是 True.

你应该做的是摆脱 mc_x、mc_y、spider_x 和 spider_y 变量并使用 mcrect 和 spirect 跟踪图像的位置，例如而不是

mcrect = mc.get_rect()
...
screen.blit(mc,(mc_x,mc_y))
...
mc_y += 3

做

mcrect = mc.get_rect(top=20, left=20)
...
screen.blit(mc, mcrect)
...
mcrect.move_ip(0, 3)

等等等
