Unity编辑器之导入导出获取路径对话框

选中一个图片，点击 “Save Texture to file”按钮

在Editor文件夹下创建脚本
using UnityEngine;
using System.Collections;
using UnityEditor;
using System.IO;

public class TestEditor : EditorWindow
{
    [MenuItem("Examples/Save Texture to file")]
    static void Apply()
    {

        Texture2D texture = Selection.activeObject as Texture2D; //选中一个图片
        if (texture == null)
        {  //如果没选图片，显示提示对话框
            EditorUtility.DisplayDialog(
                "Select Texture",
                "You Must Select a Texture first!",
                "Ok");
            return;
        }
        //获取路径
        string path = EditorUtility.SaveFilePanel(
                "Save texture as PNG",
                "",
                texture.name + ".png",
                "png");

        if (path.Length != 0)
        {
            // Convert the texture to a format compatible with EncodeToPNG
            if (texture.format != TextureFormat.ARGB32 && texture.format != TextureFormat.RGB24)
            {
                Texture2D newTexture = new Texture2D(texture.width, texture.height);
                newTexture.SetPixels(texture.GetPixels(0), 0);
                texture = newTexture;
            }
            var pngData = texture.EncodeToPNG();
            if (pngData != null)
                File.WriteAllBytes(path, pngData);
        }
    }
}
