Question

我的播放器碰到物体时会不断飞离地图。

在我的游戏中，玩家可以与墙壁和物体碰撞-它们都遵循相同的碰撞代码。我在屏幕的底部有一排盒子，每个盒子之间都有间隔。当玩家碰到一个盒子时，他们会不断在屏幕上拖动，直到飞离地图为止。

如果玩家在盒子和墙壁之间的小距离内奔跑，他们也会从地图上掉下来。

我知道它与我的碰撞代码有关，但是我不知道是什么。我只是按照与墙相同的碰撞规则将框添加到代码中，所以这才刚刚成为一个问题。

这是墙壁和盒子的一般碰撞代码

def collide_hit_rect(one, two):
    return one.hit_rect.colliderect(two.rect)

def collide_with_walls(sprite, group, dir):
    if dir == 'x':
        hits = pg.sprite.spritecollide(sprite, group, False, collide_hit_rect)
        if hits:
            if sprite.vel.x > 0:
                sprite.pos.x = hits[0].rect.left - sprite.hit_rect.width / 2
            if sprite.vel.x < 0:
                sprite.pos.x = hits[0].rect.right + sprite.hit_rect.width / 2
            sprite.vel.x = 0
            sprite.hit_rect.centerx = sprite.pos.x
    if dir == 'y':
        hits = pg.sprite.spritecollide(sprite, group, False, collide_hit_rect)
        if hits:
            if sprite.vel.y > 0:
                sprite.pos.y = hits[0].rect.top - sprite.hit_rect.height / 2
            if sprite.vel.y < 0:
                sprite.pos.y = hits[0].rect.bottom + sprite.hit_rect.height / 2
            sprite.vel.y = 0
            sprite.hit_rect.centery = sprite.pos.y

玩家与之碰撞的盒子的代码看起来相同-只是说盒子而不是墙。这是我的播放器的详细信息：

class Player(pg.sprite.Sprite):
def __init__(self, game, x, y):
    self.layer = PLAYER_LAYER
    self.groups = game.all_sprites
    pg.sprite.Sprite.__init__(self, self.groups)
    self.game = game
    self.image = game.player_img
    self.rect = self.image.get_rect()
    self.rect.center = (x, y)
    self.hit_rect = PLAYER_HIT_RECT
    self.hit_rect.center = self.rect.center
    self.vel = vec(0, 0)
    self.pos = vec(x, y)
    self.rot = 0
    self.last_shot = 0
    self.health = PLAYER_HEALTH
    self.item = False
    self.box = True


def get_keys(self):
    self.rot_speed = 0
    self.vel = vec(0, 0)
    keys = pg.key.get_pressed()
    if keys[pg.K_LEFT] or keys[pg.K_a]:
        self.rot_speed = PLAYER_ROT_SPEED
    if keys[pg.K_RIGHT] or keys[pg.K_d]:
        self.rot_speed = -PLAYER_ROT_SPEED
    if keys[pg.K_UP] or keys[pg.K_w]:
        self.vel = vec(PLAYER_SPEED, 0).rotate(-self.rot)
    if keys[pg.K_DOWN] or keys[pg.K_s]:
        self.vel = vec(-PLAYER_SPEED / 2, 0).rotate(-self.rot)
    if keys[pg.K_RETURN]:
        if self.box == True:
            #self.player.WEAPON.PLACED = True
            now = pg.time.get_ticks()
            if now - self.last_shot > LASER_RATE:
                self.last_shot = now
                dir = vec(1, 0).rotate(-self.rot)
                pos = self.pos + BARREL_OFFSET.rotate(-self.rot)
                Laser(self.game, pos, dir)
        else:
            pass

    if keys[pg.K_SPACE]:
        if self.item == True:
            #self.player.WEAPON.PLACED = True
            now = pg.time.get_ticks()
            if now - self.last_shot > SHARD_RATE:
                self.last_shot = now
                dir = vec(1, 0).rotate(-self.rot)
                pos = self.pos + BARREL_OFFSET.rotate(-self.rot)
                Shard(self.game, pos, dir)
        else:
            pass



def update(self):
    self.get_keys()
    self.rot = (self.rot + self.rot_speed * self.game.dt) % 360
    self.image = pg.transform.rotate(self.game.player_img, self.rot)
    self.rect = self.image.get_rect()
    self.rect.center = self.pos
    self.pos += self.vel * self.game.dt
    self.hit_rect.centerx = self.pos.x
    collide_with_walls(self, self.game.walls, 'x')
    self.hit_rect.centery = self.pos.y
    collide_with_walls(self, self.game.walls, 'y')
    self.rect.center = self.hit_rect.center
    collide_with_boxs(self, self.game.boxs, 'x')
    self.hit_rect.centery = self.pos.y
    collide_with_boxs(self, self.game.boxs, 'y')
    self.rect.center = self.hit_rect.center

我不确定我做错了什么或为什么会这样。即使击中游戏中的其他物体，如果它不是墙壁，玩家也会做这种炫目的颠簸，将自己向上推并围绕该物体，直到不再接触为止。
