我想做一种“关卡编辑器”作为练习。 我有以下代码:
import pygame
running = True
pygame.init()
screen = pygame.display.set_mode((800, 500))
class Cube:
def update(self):
self.cx, self.cy = pygame.mouse.get_pos()
self.square = pygame.Rect(self.cx, self.cy, 50, 50)
def draw(self):
pygame.draw.rect(screen, (255, 0, 0), self.square)
cube = Cube()
drawing_cube = False
drawing_cube2 = False
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.MOUSEBUTTONDOWN:
cube.update()
drawing_cube = True
screen.fill((0, 255, 0))
if drawing_cube:
cube.draw()
pygame.display.flip()
pygame.quit()
但是,它不会创建多个正方形。它只是重新定位已经创建的正方形。

它完全按照您的要求进行操作:更新游戏中唯一的一个Cube
对象,然后重新绘制屏幕和该对象。如果要多个多维数据集,则必须创建每个多维数据集。也许是这样的:
cube_list = [] # List of all cubes
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.MOUSEBUTTONDOWN: # Make a new cube
cube = Cube()
cube.update()
cube_list.append(cube)
drawing_cube = True
screen.fill((0, 255, 0))
if drawing_cube: #New cube made; draw them all.
for cube in cube_list:
cube.draw()
pygame.display.flip()
现在,作为学生的练习,您可以简化一下,使其仅将最新的多维数据集添加到现有屏幕上,而不是为每个新的多维数据集重新绘制整个游戏区域吗?

谢谢,修剪!但是对于那些在我后面阅读本文的人,这里是完整的代码:
import pygame
cube_list = []
running = True
pygame.init()
screen = pygame.display.set_mode((800, 500))
class Cube:
def update(self):
self.cx, self.cy = pygame.mouse.get_pos()
self.square = pygame.Rect(self.cx, self.cy, 50, 50)
def draw(self):
pygame.draw.rect(screen, (255, 0, 0), self.square)
cube = Cube()
drawing_cube = False
drawing_cube2 = False
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.MOUSEBUTTONDOWN: # Make a new cube
cube = Cube()
cube.update()
cube_list.append(cube)
drawing_cube = True
screen.fill((0, 255, 0))
if drawing_cube: #New cube made; draw them all.
for cube in cube_list:
cube.draw()
pygame.display.flip()
pygame.quit()
干杯!
