Unity之EditorGUILayout-一

转载：http://blog.csdn.net/liqiangeastsun/article/details/42173029
一般情况下，在Inspector面板上只能显示public类型的基本变量如 float int string 等
例如 Rect Color Texture等类型的，声明为 public也不会显示出来，下面利用编辑器类来让不能显示的类型显示在Inspector面板
如下显示了 Color， AnimationCurve， Rect，Texture

点击 颜色跳出如下 窗口来修改颜色

点击曲线跳出如下窗口

可以点击曲线的灰色部分右键， 点击 Add Key 添加一个点，然后调整位置
本例创建两个脚本，一个在Editor文件夹下 创建为 InspectorTest
另一个不放在Editor文件夹下 Test
Test脚本如下

using UnityEngine;  
using System.Collections;  
  
public class Test : MonoBehaviour {  
    public Color myColor;  
    public AnimationCurve curveX = AnimationCurve.Linear(0, 0, 10, 10);  
    public AnimationCurve curveY = AnimationCurve.Linear(0, 0, 10, 10);  
    public AnimationCurve curveZ = AnimationCurve.Linear(0, 0, 10, 10);  
  
    public Rect myRect;  
    public Texture myTexture;  
    // Update is called once per frame  
    void Update () {  
  
        if (Input.GetKeyUp(KeyCode.A))  
        {  
            print("MyColor   "+myColor);  //打印颜色  
            print("curveX "+ curveX.Evaluate(Time.time));   //利用时间获取曲线的值  
            print("curveY  "+curveY.Evaluate(Time.time));   //利用时间获取曲线的值  
            print("curveZ  "+ curveZ.Evaluate(Time.time));  
            print("myRect    "+myRect);  //打印 Rect的 x ，y ，width， height  
            print("myTexture    "+myTexture); //打印Texture  
        }  
        //根据三个曲线，实时的获取他们的值，来设置该对象的位置  
        transform.position = new Vector3(curveX.Evaluate(Time.time), curveY.Evaluate(Time.time), curveZ.Evaluate(Time.time));  
    }  
}  

放在Editor文件夹中的 InspectorTest 脚本  
using UnityEngine;  
using System.Collections;  
using UnityEditor;  
  
[CustomEditor(typeof(Test))]  
public class InspectorTest : Editor {  
  
    public override void OnInspectorGUI()  //该方法会绘制在Inspector面板上  
    {  
        Test myTest = (Test)target;  
       //颜色  
        myTest.myColor = EditorGUILayout.ColorField("New Color", myTest.myColor);  
       //曲线  
        myTest.curveX = EditorGUILayout.CurveField("Animation On X", myTest.curveX);  
        myTest.curveY = EditorGUILayout.CurveField("Animation On Y", myTest.curveY);  
        myTest.curveZ = EditorGUILayout.CurveField("Animation On Z", myTest.curveZ);  
       // Rect   
        myTest.myRect = EditorGUILayout.RectField("窗口  ", myTest.myRect);  
//Texture   
        myTest.myTexture = EditorGUILayout.ObjectField("tie tu", myTest.myTexture, typeof(Texture), true) as Texture;  
    }  
}
