我正在尝试构建我的第一个平台游戏。到目前为止,我可以左右移动,但是不幸的是,在实现碰撞和重力时遇到了无法修复的错误。如果它落在平台上,我的播放器会像蜘蛛侠一样不断消散。角色仍然存在,并降落在平台上,但不幸的是,他变得不可见。没有错误消息,我怀疑与冲突检查有关。
hits = pygame.sprite.spritecollide(object, allPlatforms, False)
if hits:
object.rect.y = hits[0].rect.top + 1
object.vy = 0
print(object.rect.midbottom)
它会在代码中打印出Players的位置,并且该播放器仍然存在并且可以移动,但是它没有显示。我做了什么使角色消失的事情?
import pygame

all_sprites.add(p1)
allPlatforms.add(p1)
def moveCharacter(object):
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
object.vx += -2

object.vx = 0
if (abs(object.vx) > 10):
if(object.vx < 0):
object.vx = -10
else:
object.vx = 10
object.vy = object.vy + 1
object.rect.x += object.vx
object.rect.y += object.vy
hits = pygame.sprite.spritecollide(object, allPlatforms, False)
if hits:
object.rect.y = hits[0].rect.top + 1
object.vy = 0
print(object.rect.midbottom)
running = True
while running:
clock.tick(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
moveCharacter(player)
#Update State
all_sprites.update()
#Render
screen.fill(BLACK)
all_sprites.draw(screen)
#screen.blit(player.icon, (20, 40))
pygame.display.flip()
pygame.quit()
我做错什么了吗?谢谢!
答案 0 :(得分:0)
rect的y
属性与top
坐标相同,因此在此处object.rect.y = hits[0].rect.top + 1
将播放器精灵的顶部设置为平台精灵的顶部。而且,如果该平台稍后出现在sprite组中,则它将在播放器播放后变白,并且播放器将不可见。
只需将该行更改为object.rect.bottom = hits[0].rect.top + 1
。
