嗨,我在实现自己的想法时遇到了一些麻烦。我首先想用两次鼠标点击绘制矩形,但它没有正常工作,所以我把它缩小到这个:用一个鼠标点击绘制固定大小的矩形。 然而它仍然没有工作/...
import pygame
windowSize = (500,500)
white = (255,255,255)
black = (0,0,0)
pygame.init()
screen = pygame.display.set_mode(windowSize)
running = 1
while running:
screen.fill(white)
pygame.display.update()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
running = 0
问题在哪里
elif event.type == pygame.MOUSEBUTTONDOWN:
rect = pygame.Rect(event.dict["pos"],(30,50))
pygame.draw.rect(screen,black,rect,1)
pygame.display.flip()
我知道我的代码可能存在很多概念错误......请帮忙!
答案 0 :(得分:1)
每个刻度都在整个屏幕上填充白色。因此,在您实际绘制屏幕后,在下一个刻度上再次变为空白。只需将screen.fill(white)
移出主循环:
import pygame
windowSize = (500,500)
white = (255,255,255)
black = (0,0,0)
pygame.init()
screen = pygame.display.set_mode(windowSize)
running = 1
screen.fill(white)
while running:
pygame.display.update()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
elif event.type == pygame.MOUSEBUTTONDOWN:
rect = pygame.Rect(event.dict["pos"],(30,50))
pygame.draw.rect(screen,black,rect,1)
pygame.display.flip()
