Question

我正在使用Python和Pygame开发一个驾驶模拟器。但是，我在处理汽车方面遇到了一些麻烦。每当我转弯时，汽车似乎漂浮在冰上或潮湿的路面上。有没有简单的方法可以防止这种情况发生？

从代码中摘录：

class Player(pg.sprite.Sprite):
def __init__(self, game, x, y):
    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.hit_rect = PLAYER_HIT_RECT
    self.hit_rect.center = self.rect.center
    self.vel = vec(0,0)
    self.acc = vec(0,0)
    self.pos = vec(x, y) * TILESIZE
    self.rot = 0

def get_keys(self): #Where all the keypresses are detected and assigned to a feature e.g. movement.
    self.rot_speed = 0
    self.acc = vec(0, 0)
    keys = pg.key.get_pressed()
    if keys[pg.K_w]:
        self.acc = vec(PLAYER_SPEED, 0).rotate(-self.rot)
    if keys[pg.K_a]: # This part of the code is used to reverse the functions of the A and D key, so when you want to reverse, they actually rotate the sprite in the correct direction.
        self.rot_speed = PLAYER_ROT_SPEED
    if keys[pg.K_d]:
        self.rot_speed = -PLAYER_ROT_SPEED
    if keys[pg.K_s]:
        self.acc = vec(-PLAYER_SPEED /5, 0).rotate(-self.rot)
    self.acc += self.vel * PLAYER_FRICTION
    self.vel += self.acc
    self.pos += self.vel+ 0.02 * self.acc
    self.rect.center = self.pos

感谢您的帮助！（某些注释不正确，因为它来自较旧版本的游戏）
