Python Can';不要让rect在pygame中更改颜色?
因此,我在pygame中遇到了一个问题,我试图制作一个迷宫生成器,用户可以点击网格中的一个正方形,而这个正方形会变成黑色。虽然我在调试器/打印语句中看到颜色值发生了变化,但在ui中没有看到任何变化。谁能帮我看看吗 我的源代码:Python Can';不要让rect在pygame中更改颜色?,python,pygame,Python,Pygame,因此,我在pygame中遇到了一个问题,我试图制作一个迷宫生成器,用户可以点击网格中的一个正方形,而这个正方形会变成黑色。虽然我在调试器/打印语句中看到颜色值发生了变化,但在ui中没有看到任何变化。谁能帮我看看吗 我的源代码: import pygame import math WIDTH = 800 # initialize window WINDOW = pygame.display.set_mode((WIDTH, WIDTH)) # always square pygame.disp

我认为您的生成网格
功能有问题
而不是
def make_grid(rows, width, height):
grid = []
gap = width // height # this will always be 1
for i in range(rows):
grid.append([])
for j in range(rows):
spot = Spot(i, j, gap, height) # all your spots a 1px wide and 800px tall
grid[i].append(spot)
return grid
使用
这似乎奏效了:
哦,是的。我没有想到它是一个正方形,宽度总是==高度。
def make_grid(rows, width, height):
grid = []
gap = width // rows # TODO: use better variable names
for i in range(rows):
grid.append([])
for j in range(rows):
spot = Spot(i, j, gap, gap)
grid[i].append(spot)
return grid
