如何解决左上角的精灵消失了，我不知道如何修复它 PyGame 随机生成的精灵迷宫
所以我正在尝试制作一个迷宫游戏，迷宫是使用精灵随机生成的，但是，左上角的单元格总是空的，我不知道如何在不破坏删除某些单元格的代码的情况下解决这个问题取决于计算机采取的方向。如果有人知道如何解决这个问题，请帮忙。
代码：
import pygame,random,time
pygame.init()
SCREEN_WIDTH = 810
SCREEN_HEIGHT = 810
screen = pygame.display.set_mode((SCREEN_WIDTH,SCREEN_HEIGHT))
class Cell(pygame.sprite.Sprite):
def __init__(self,x,y):
super().__init__()
self.x = x
self.y = y
self.size = 80
self.N = True
self.E = True
self.S = True
self.W = True
self.image = pygame.Surface([80,80])
self.image.fill((255,255,255))
self.rect = self.image.get_rect()
# self.rect.x = x
# self.rect.y = y
def update(self):
if self.N:
pygame.draw.rect(screen,(255,0),[self.x+1,self.y+1,self.size,1])
if self.W:
pygame.draw.rect(screen,1,self.size])
if self.S:
pygame.draw.rect(screen,self.y+self.size+1,1])
if self.E:
pygame.draw.rect(screen,[self.x+self.size+1,self.size+1])
def clear_wall(self,side):
if side.lower() == "west":
self.W = False
elif side.lower() == "east":
self.E = False
elif side.lower() == "north":
self.N = False
elif side.lower() == "south":
self.S = False
def find_cell(cells,current,direction):
for c in cells:
if direction == "east":
if c.x == current.x + 80 and c.y == current.y:
return c # found the correct cell,so return it
if direction == "west":
if c.x == current.x - 80 and c.y == current.y:
return c
if direction == "south":
if c.x == current.x and c.y == current.y + 80:
return c
if direction == "north":
if c.x == current.x and c.y == current.y - 80:
return c
def getoppositeDir(direction):
if direction.lower() == "east":
return "west"
elif direction.lower() == "west":
return "east"
elif direction.lower() == "north":
return "south"
elif direction.lower() == "south":
return "north"
def generate_maze(cells):
current = cells.sprites()[random.randint(0,79)] # starting point
# Set current cell to initial starting point
direction = "south"
for x in range(800):
joining_cell = find_cell(cells,direction)
current.clear_wall(direction)
try:
joining_cell.clear_wall(getoppositeDir(direction))
current = joining_cell # move to the new current cell
direction = random.choice(["north","east","south","west"])
except:
pass
def Main():
cells = pygame.sprite.Group()
for x in range(10):
for y in range(10):
cells.add(Cell(y * 80,x * 80))
generate_maze(cells)
clock = pygame.time.Clock()
onRun = True
while onRun:
for event in pygame.event.get():
if event.type == pygame.QUIT:
runOn = False
screen.fill([255,255])
cells.update()
cells.draw(screen)
pygame.display.flip()
clock.tick(60)
if __name__ == '__main__':
pygame.init()
Main()
pygame.quit()
解决方法
我想我修好了。
问题在于您没有定位图像，因此所有单元格的白色表面在 (0,0) 处闪烁，这就是左上角单元格从来没有可见线条的原因。
我通过使用 surface.get_rect(top_left=location) 将 rect 设置为位置来解决这个问题。
但随后所有单元格都被覆盖了，所以我颠倒了绘制和更新步骤。
IDK，希望这会有所帮助。
