给你一个粗略变更的插件，还没来得及美化，将就用吧。

谢谢

找到项目下的/js/rpg_sprites.js,所有特效显示效果都是在这个类里面定义的。
找到这个函数：
Spriteset_Map.prototype.createLowerLayer = function() {
Spriteset_Base.prototype.createLowerLayer.call(this);
this.createParallax();
this.createTilemap();
this.createCharacters();
this.createShadow();
// this.createDestination();
this.createWeather();
};
注释掉this.createDestination()即可，如果你想显示自己的光标样式，修改createDestination函数即可，不建议直接修改，可以以插件的模式来扩展，参见二楼提供的插件方法。
