如何用flashfxp上传网站免费推广工具有哪些

关键词：UnityEditor、可视化节点编辑、Unity编辑器自定义窗口工具 

 使用Newtonsoft.Json、UnityEditor相关接口实现
主要代码：

Handles.DrawBezier(起点，终点，起点切线向量，终点切线向量，颜色，null, 线粗度) 绘制贝塞尔曲线

Handles.DrawAAPolyLine(线粗度，顶点1, 顶点2, ...) 根据线段点绘制不规则线段

GUI.Window(id, rect, DrawNodeWindow, 窗口标题);  
void DrawNodeWindow(int id) 传入的id即GUI.Window第一个参数，一般传节点唯一标识ID。

LinkObj类是节点类，里面有一个位置pos数据是存储该节点窗口位于编辑器的位置SerializableVector2类型是一个可被Json序列化的Vector2，不然无法被序列化。
