血小板卡在墙上

Question

我好像和我在皮格特建的那个平台有矛盾。当我从左边接近他们的时候，我可以把它们弄到墙上去。当接近墙壁时，我把x速度设为零，但我仍然可以进去。有人能帮我一下吗？

我正在尝试做一个游戏，玩家必须跑动到赛道的尽头。这个平台将是一个2d，非滚动的游戏，当它完成。

import pygame as pg


pg.init()
screen = pg.display.set_mode((640, 480))
BG_COLOR = pg.Color(173, 216, 230)

def main():
    clock = pg.time.Clock()
    image = pg.Surface((50, 50))
    image.fill(pg.Color('red'))
    player_rect = image.get_rect(topleft=(200, 200))
    image_ground = pg.Surface((1000, 50))
    image_ground.fill(pg.Color('black'))
    ground_rect = image_ground.get_rect(topleft=(0, 430))
    image_ground2 = pg.Surface((300, 50))
    image_ground2.fill(pg.Color('black'))
    ground_rect2 = image_ground2.get_rect(topleft=(0, 330))
    image_ground3 = pg.Surface((50, 50))
    image_ground3.fill(pg.Color('black'))
    ground_rect3 = image_ground3.get_rect(topleft=(400, 230))
    screen_rect = screen.get_rect()
    image_ground3.fill(pg.Color('black'))
    ground_rect3 = image_ground3.get_rect(topleft=(400, 230))
    screen_rect = screen.get_rect()
    xv = 0
    yv = 0
    level = 1

    while True:
        for event in pg.event.get():
            if event.type == pg.QUIT:
                return
        pressed = pg.key.get_pressed()
        if pressed[pg.K_RIGHT]:
            xv = xv + 0.85
        if pressed[pg.K_LEFT]:
            xv = xv - 0.85
        xv = xv * 0.9
        player_rect.x += xv
        if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
          player_rect.y -= 1
          if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
            player_rect.y -= 1
            if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
              player_rect.y -= 1
              if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
                player_rect.y -= 1
                if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
                  player_rect.y -= 1
                  if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
                    player_rect.y += 5
                    player_rect.x -= xv
                    if pressed[pg.K_UP]:
                      if xv > 0:
                        xv = -8
                      else:
                        xv = 8
                      yv = 13
                    else:
                      xv = 0
        yv = yv - 1
        player_rect.y -= yv
        if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
          player_rect.y += yv
          yv = 0
        player_rect.y += 1
        if player_rect.colliderect(ground_rect) or player_rect.colliderect(ground_rect2) or player_rect.colliderect(ground_rect3):
          if pressed[pg.K_UP]:
            yv = 13
        player_rect.y -= 1
        player_rect.clamp_ip(screen_rect)

        screen.fill(BG_COLOR)
        screen.blit(image, player_rect)
        screen.blit(image_ground, ground_rect)
        screen.blit(image_ground2, ground_rect2)
        screen.blit(image_ground3, ground_rect3)

        pg.display.flip()
        clock.tick(60)


if __name__ == '__main__':
    main()
    pg.quit()

Answer 1

我想出了我自己问题的答案。游戏因为四舍五入而变得很糟糕，游戏被移动0.000000000000001弄糊涂了，还把我塞进了墙上。在移动播放器之前，我用十五号四舍五入来修正它。

Answer 2

当方向键被按下，你移动到墙上时，你会弹出(墙跳)。但如果你放开钥匙碰墙，你就被卡住了。我不知道如何解决这个问题，但是相关的帖子可能会对你有帮助。:)
