【Unity】编辑器中实现可拖动窗口

不得不吐槽CSDN的编辑器不好用 ,学习中

参考国外大牛的文章写得可拖动小窗口 , 还是不错滴 




using UnityEngine;

using UnityEditor;

public class NodeEditor : EditorWindow

{

    Rect window1;

    Rect window2;

    [MenuItem("Window/Node editor")]

    static void ShowEditor()

    {

        NodeEditor editor = EditorWindow.GetWindow<NodeEditor>();

        editor.Init();

    }

    public void Init()

    {

        window1 = new Rect(10, 10, 100, 100);

        window2 = new Rect(210, 210, 100, 100);

    }

    void OnGUI()

    {

        DrawNodeCurve(window1, window2); 

        BeginWindows();

        window1 = GUI.Window(1, window1, DrawNodeWindow, "Window 1");   

        window2 = GUI.Window(2, window2, DrawNodeWindow, "Window 2");

        EndWindows();

    }

    void DrawNodeWindow(int id)

    {

        GUI.DragWindow();

    }

    void DrawNodeCurve(Rect start, Rect end)

    {

        Vector3 startPos = new Vector3(start.x + start.width, start.y + start.height / 2, 0);

        Vector3 endPos = new Vector3(end.x, end.y + end.height / 2, 0);

        Vector3 startTan = startPos + Vector3.right * 50;

        Vector3 endTan = endPos + Vector3.left * 50;

        Color shadowCol = new Color(0, 0, 0, 0.06f);

        for (int i = 0; i < 3; i++) // Draw a shadow

            Handles.DrawBezier(startPos, endPos, startTan, endTan, shadowCol, null, (i + 1) * 5);

        Handles.DrawBezier(startPos, endPos, startTan, endTan, Color.black, null, 1);

    }

}
