基于平铺的运动pygame

Question

我试图使用Pygame和Tiled一起制作游戏。问题是，当我试图移动我的角色时，它会从一个瓦片到另一个瓦片（16x16瓦片网格）如此快速，即使我降低了fps，它看起来像是从一个瓦片传送到另一个瓦片（我的运动增加了16像素，因此它与地图匹配）。我想要实现的有点像当你移动口袋妖怪时会发生什么，当你从一块瓷砖移动到另一块瓷砖时你可以看到平滑的动画（我使用Pyganim进行步行动画）。

while running:
    ColDetectposX = gameMap.get_tile_properties(((posX/16)+1),((posY/16)),1)
    ColDetectnegX = gameMap.get_tile_properties(((posX/16)-1),((posY/16)),1)
    ColDetectposY = gameMap.get_tile_properties(((posX/16)),((posY/16)+1),1)
    ColDetectnegY = gameMap.get_tile_properties(((posX/16)),((posY/16)-1),1)
    if facedown:
        screen.blit(chardown,(posX,posY))
    elif faceup:
        screen.blit(charup,(posX,posY))
    elif faceleft:
        screen.blit(charleft,(posX,posY))
    elif faceright:
        screen.blit(charright,(posX,posY))

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()
            quit()

    if event.type == pygame.KEYDOWN:
        walking = True

我希望我能清楚地解释我想做什么，如果不是，我会尽力尽力回答。我不知道面向对象编程，由于我的日程安排，我没有时间学习，所以我希望你能不用课程来帮助我。如果相关，我也使用python 3.4.4。
