Question

我正在使用spritemanager，并试图在Renpy中进行边缘锁定的侧滚轴运动。但是，当按下向左和向右箭头键然后迅速松开时，会出现问题：

精灵倾向于在其空闲的精灵中移动（即使应该使用charWalk == True更改为行走精灵集）。
每次快速按下时，子图形的移动点（从其自由移动状态到锁定中心状态）就会一点一点地向右移动。如果我在角色处于锁定状态时快速按下，则精灵会在转移点停留一会儿，然后才能“释放”，并能够再次进入自由移动状态。

如果一次又一次按下并释放左箭头键和右箭头键，这两个问题都不会发生（并且可以按预期工作）。

def engine_updater(st):
    if store.time_counter:
        store.time_counter -= .001
        if store.time_counter <= 0.0:
            store.time_counter = None
            store.player_sprites.append(Character_Sprite())
    g_s = store.player_sprites

    if g_s:
        for sprite in g_s[:]:
            sprite.update()
            sprite.movement()
    return .001

def engine_event(ev, x, y, st):
    if ev.type == KEYDOWN and ev.key in BUTTONS:

        pressed = pygame.key.get_pressed()

        if pressed[u_arrow] and not u_arrow in store.control_flags:
            store.control_flags.append(u_arrow)
        if pressed[d_arrow] and not d_arrow in store.control_flags:
            store.control_flags.append(d_arrow)
        if pressed[l_arrow] and not l_arrow in store.control_flags:
            store.control_flags.append(l_arrow)
            store.spriteFlip = True
            store.charWalk = True
        elif pressed[r_arrow] and not r_arrow in store.control_flags:
            store.control_flags.append(r_arrow)
            store.spriteFlip = False
            store.charWalk = True

    if ev.type == KEYUP and ev.key in BUTTONS:
        if ev.key in store.control_flags:
            store.control_flags.remove(ev.key)

在Character_Sprite类中：

    def movement(self):
        if store.control_flags:
            if l_arrow in store.control_flags:
                self.dist -= self.move_amt
                if self.dist > -175 or self.dist < -2993:
                    self.x -= self.move_amt
                    store.charCentered = False
                else:
                    self.x -= 0
                    store.charCentered = True

            elif r_arrow in store.control_flags:
                self.dist += self.move_amt
                if self.dist > -175 or self.dist < -2993:
                    self.x += self.move_amt
                    store.charCentered = False
                else:
                    self.x += 0 
                    store.charCentered = True
    def update(self):
        if self.delay_frames > 0:
                self.delay_frames -= 1
                return
        self.delay_frames = self.max_delay
            self.frame_number += 1
            if self.frame_number >= self.max_frames:
                self.frame_number = 0

            self.refresh_sprite()

    def refresh_sprite(self):
            self.tx, self.ty, self.tz = self.show.x, self.show.y, self.show.zorder
            self.show.destroy()
            self.sprite = self.frame_list[self.frame_number]
        if spriteFlip == True:
                self.sprite = im.Flip(self.sprite,True,False)

        self.show = MNG.create(self.sprite)
        self.show.x, self.show.y, self.show.zorder = self.tx, self.ty, self.tz

为了方便查看，我删除了一些代码，但是如果需要，我可以显示更多代码。
