如何在 Unity Editor 中绘制自定义菜单

using UnityEngine

using UnityEditor

using System.Collections

// This example shows how to create a context menu inside a custom EditorWindow.

// context-click the green area to show the menu

public class GenericMenuExample : EditorWindow

{

[MenuItem("Example/Open Window")]

static void Init()

{

var window = GetWindow<GenericMenuExample>()

window.position = new Rect(50, 50, 250, 60)

window.Show()

}

void Callback(object obj)

{

Debug.Log("Selected: " + obj)

}

void OnGUI()

{

Event currentEvent = Event.current

Rect contextRect = new Rect(10, 10, 100, 100)

EditorGUI.DrawRect(contextRect, Color.green)

if (currentEvent.type == EventType.ContextClick)

{

Vector2 mousePos = currentEvent.mousePosition

if (contextRect.Contains(mousePos))

{

// Now create the menu, add items and show it

GenericMenu menu = new GenericMenu()

menu.AddItem(new GUIContent("MenuItem1"), false, Callback, "item 1")

menu.AddItem(new GUIContent("MenuItem2"), false, Callback, "item 2")

menu.AddSeparator("")

menu.AddItem(new GUIContent("SubMenu/MenuItem3"), false, Callback, "item 3")

menu.ShowAsContext()

currentEvent.Use()

}

}

}

}

unity添加天空盒有两种方法，分别为向场景添加和向摄像机添加。首先我们在assert里面导入skybox素材。

向camera里导入：

点击camera或者main camera，再点击component，选renderin,点skybox.再inspector里面会成这样，注意，第一个框框必须是skybox。然后在第二个框框里面导入素材。

向scene里导入：

在edit里点render setting即可。再在红框框处选择。

scene里面添加skybox什么时候都可以看到，camera只有在该摄像机里面可以看到。
