Xauxas 筆記

已經好久沒來「痞客邦」來寫關於Unity 技術文章，都在Goolge Blooger 那邊撰寫比較多 

回歸主題...此文章內容是Unity裡面Sprite 裡面的功能。

不多說...直接看程式碼之範例吧

忘了一件事情，此程式碼操作使用到Unity Editor 外掛編輯元件哦。

-----------------

Unity Edtor (C#):

using UnityEngine;
using System.Collections;
using UnityEditor;
using System.Collections.Generic;

public class SpriteProcessor : EditorWindow
{

    private Vector2 vector2Label;          // 標籤位置(BeginScrollView 用的)
    private GUIStyle style = new GUIStyle();   // GUI 風格
    private string spriteSegmentationType = "";  // Sprite 分割像素
    private string spriteName = "";        // Sprite 分格後名稱
    private int spriteTitleNumber = 0;   // 分格後的名稱編號
    private int spriteSegmentationNumber;   // 分割數值字串轉型



    //  呼叫視窗
    [MenuItem(測試/Sprite寫法)]
    public static void spriteWindowSetting()
    {
        SpriteProcessor windows = EditorWindow.GetWindow(typeof(SpriteProcessor), true, "Sprite 自動分割") as SpriteProcessor;
        windows.Show();
    }

  

    // 選擇貼圖(Sprite)
    static Object[] getSelectTexture()
    {
        return Selection.GetFiltered(typeof(Texture2D), SelectionMode.DeepAssets);
    }

    void OnGUI()
    {

        style.fontSize = 18;
        style.normal.textColor = Color.white;

        GUI.Label(new Rect(0, 0, 100, 30), "圖片分割", style);

        // Sprite 分割像素
        GUILayout.BeginArea(new Rect(0, 30, 300, 100));
        GUILayout.BeginHorizontal();
        GUILayout.Label("Sprite 分割像素");
        GUILayout.EndHorizontal();
        GUILayout.EndArea();

        // Sprite 分割像素輸入
        GUILayout.BeginArea(new Rect(150, 30, 150, 100));
        GUILayout.BeginHorizontal();
        spriteSegmentationType = GUILayout.TextField(spriteSegmentationType);
        GUILayout.EndHorizontal();
        GUILayout.EndArea();

        // Sprite標籤
        GUILayout.BeginArea(new Rect(0, 110, 300, 100));
        GUILayout.BeginHorizontal();
        GUILayout.Label("Sprite 標簽名稱");
        GUILayout.EndArea();
        GUILayout.EndHorizontal();

        // Sprite標籤輸入
        GUILayout.BeginArea(new Rect(148, 110, 150, 100));
        GUILayout.BeginHorizontal();
        spriteName = GUILayout.TextField(spriteName);
        GUILayout.EndHorizontal();
        GUILayout.EndArea();

        GUILayout.BeginArea(new Rect(200, 150, 100, 100));
        GUILayout.BeginHorizontal();
        if (GUILayout.Button("確定"))
            SetPivots();
        GUILayout.EndHorizontal();
        GUILayout.EndArea();
    }
 
    // 分割動作
    void SetPivots()
    {
        spriteTitleNumber = 0;
        // 判斷轉型成功執行分割
        if (int.TryParse(spriteSegmentationType, out spriteSegmentationNumber))
        {
            Object[] textures = getSelectTexture();
            Selection.objects = new Object[0];

            SpriteMetaData d = new SpriteMetaData();
            
            foreach (Texture2D texture in textures)
            {
                string path = AssetDatabase.GetAssetPath(texture);
                TextureImporter ti = AssetImporter.GetAtPath(path) as TextureImporter;
                ti.isReadable = true;
                List newData = new List();
                newData.Remove(d);
                for (int x = 0; x < texture.width; x += spriteSegmentationNumber)
                {
                    for (int y = 0; y < texture.height; y += spriteSegmentationNumber)
                    {
                        d.alignment = 9;
                        d.pivot = new Vector2(0.5f, 0.5f);
                        d.name = spriteName + "_" + (spriteTitleNumber += 1);
                        d.rect = new Rect(x, y, spriteSegmentationNumber, spriteSegmentationNumber);
                        newData.Add(d);
                    }
                }
                ti.spritesheet = newData.ToArray();
                AssetDatabase.ImportAsset(path, ImportAssetOptions.ForceUpdate);
            }
        }
    }
}
