我的智力竞赛游戏中的draw()函数工作不正常

Question

好吧，我正在用python做一个智力竞赛游戏。我有它，所以当你的鼠标悬停在其中一个选项上时，它会改变颜色。然而，当我尝试这样做时，有两个问题正在发生

1. 当我悬停在answer_box4上时，它的颜色实际上只发生了一些变化
2. 当我将鼠标悬停在answer_box4上时，它会更改所有框的颜色

这是代码：

try:
logname = 'c:/temp/pgzrun.log'
fontname = 'arial.ttf'

import faulthandler
faulthandler.enable()

import os, sys

script_dir = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
os.chdir(script_dir)

import pgzrun
import playsound 

import random 
from random import randint

WIDTH = 1280
HEIGHT = 720

def draw():
screen.fill("purple")
screen.draw.filled_rect(main_box, "sky blue")
screen.draw.filled_rect(timer_box, "sky blue")
screen.draw.text("Score: " + str(score), color="black", topleft=(10, 10), fontname=fontname)

for boxc in answer_boxes:
screen.draw.filled_rect(box, color)

screen.draw.textbox(str(time_left), timer_box, color=('black'), fontname=fontname)
screen.draw.textbox(question[0], main_box, color=('black'), fontname=fontname)

index = 1
for box in answer_boxes:
screen.draw.textbox(question[index], box, color=('black'), fontname=fontname)
index = index + 1

def game_over():
global question, time_left, scoredecreaserps
scoredecreaserps = 0
message = 'Game Over. You got %s questions correct' %str(numques)
question = [message, '-', '-', '-', '-', 5]
time_left = 0

def correct_answer():
global question, score, numques, time_left

numques = numques + 1
score = score + 1000

if questions:
question = questions.pop()
time_left = 10
else:
print('End of questions')
game_over()

def on_mouse_down(pos):
index = 1

for box in answer_boxes:

if box.collidepoint(pos):
print('Clicked on answer' + str(index))

if index == question[5]:
print('You got it correct!')
correct_answer()
else:
game_over()

index = index + 1

def update_time_left():
global time_left

if time_left:
time_left = time_left - 1
else:
game_over()

def score_lower():
global score

if score:
score = score - scoredecreaserps
def on_mouse_move(pos):
global color 
for box in answer_boxes:

if box.collidepoint(pos):
color = "medium blue"
print(color)

else:
color = "green yellow"
print(color)


main_box = Rect(50, 40, 820, 240)
timer_box = Rect(990, 40, 240, 240)

answer_box1 = Rect(50, 358, 495, 165)
answer_box2 = Rect(735, 358, 495, 165)
answer_box3 = Rect(50, 538, 495, 165)
answer_box4 = Rect(735, 538, 495, 165)

answer_boxes = [answer_box1, answer_box2, answer_box3, answer_box4]

scoredecreaserps = 80
color = "green yellow"
numques = 0
score = 0
time_left = 10

q1 = ["Who was the third president of the Philippines?",
'Rodrigo Duterte', 'Ramon Magsaysay', 'Jose P. Laurel',
'Fidel V. Ramos', 3]

q2 = ['When was the Philippines granted independece from the US?'
, '1977', '1946', '1935', '1907', 2]

q3 = ['When was the Philippines colonized by Spain', '1898', '1523', '1654',
'1521', 4]

questions = [q1, q2, q3]

random.shuffle(questions)

question = questions.pop(0)
clock.schedule_interval(update_time_left, 1.0)
clock.schedule_interval(score_lower, 1.0)

pgzrun.go()
except:
import traceback
with open(logname, 'a', encoding = 'utf-8') as f:
f.write(''.join(traceback.format_exc()) + 'n')

Answer 1

每次鼠标经过方框时，您都会迭代所有的方框

def on_mouse_move(pos):
global color 
for box in answer_boxes:

if box.collidepoint(pos):
color = "medium blue"
print(color)

else:
color = "green yellow"
print(color)

最后一个盒子是盒子4answer_boxes = [answer_box1, answer_box2, answer_box3, answer_box4]。最后，如果你将鼠标悬停在box1上，你会将其颜色更改为蓝色，然后在循环中移动到box2，进入"；否则"；块，并将box1的颜色更改为绿色。

为什么？我怀疑是global color的声明：每个框都指向相同的颜色。这与box4不同的事实是一致的，当单击时，会更改所有框的颜色：作为for循环中的最后一个，悬停一次会将颜色覆盖为所需的颜色，如果单击则会更新所有框的色彩。

您应该将每个框实现为具有自己颜色的对象，然后更改特定框的颜色。
