先感谢https://rpg.blue/forum.php?mod=viewthread&tid=386342 写出八方向/待机脚本的@VIPArcher 以及提出增强方案的 @doranikofu 大大。
简单测试了一下，由san shiro写的的analog move可以和8方向脚本重叠使用（SAN_AnalogMove要在方向脚本上面），另外SAN_AnalogMove2这个脚本与八方向脚本完全不兼容……

抛砖引玉，论坛有没有高手大大能使之兼容，优化成一个脚本？

没看这个rar不过八向和analog是不冲突的
唯一要改的核心代码就是analog里面这段注释掉之后analog插件就不会强制把人物八向专为四向

// 内部4方向を更新
Game_AnalogMove.prototype.updateDir4 = function(thisCharacter) {
this._dir4 = thisCharacter.direction();
//doranikofu edit for 8dir this._dir4 = this.dir8ToDir4(this.radianToDir8(this._directionRadian));
this._dir4 = this.radianToDir8(this._directionRadian);
};

复制代码

然后要注意一下行走图的素材规格，analog的方向是
789
456
123
跟八向的默认好像不太一样

自己做的时候加了点别的增强触发事件判定/朝向的，其实也不太好用，仅供参考

再一个问题就是斜向行动的时候地图上事件可能会抖动，浮点数计算的问题感觉不太好处理，试了一些办法都没彻底解决

非常感谢分享……大大的仙剑奇侠续传也有玩过，非常用心制作的良品。
移动时的浮动问题我也注意到了，会影响游戏体验……就好像自己折腾贴膜但是始终有灰……
