联机带AI版3D桌球游戏源码

这是款联机版3D桌球游戏，带有自动挂机算法，支持单机npc和联网对战。添加了瞄准辅助线功能。统一的架构，可以方便的嵌入rpg中。选手模型可以使用mmorpg中的玩家的模型。

选手动画暂时只做了一个站姿击球和一个坐姿击球，当选手和桌面发生碰撞时会从站姿切换到坐姿，中间自动添加过渡动画。手部动画配合拉杆力度使用计算预制关键帧的方法。鼠标控制拉杆角度选手移动位置时，脚步动作使用上下分身控制不同的动作。

碰撞计算是离散的，没有使用物理引擎，没有考虑到转动惯量的影响，这里是一个可以改进的地方（目前默认击球点在球的正中部位）。

AI算法，寻找最佳目标球（白色球-目标球-某个袋 - 距离之和越小越好，夹角越小越好，行进路线上不能有干扰球）。

球的碰撞及运动只同步了初始状态，后续的运动本机模拟，正常情况下简单的实现了同步。碰撞结果也暂时本机模拟，有待host处理。同步了玩家瞄准动画。
