単色テクスチャを作るエディタスクリプト
不意に適当なサイズのテクスチャが欲しくなる時がありませんか?
私はあります。
一々Photoshopやペイントを立ち上げるのが面倒だったりするので。。
なので、エディタスクリプトで手軽にテクスチャを追加できる仕組みを作りました
using System.Collections.Generic; using System.IO; using UnityEngine; using UnityEditor; namespace ScreenPocket { public class TextureUtility { [MenuItem("Assets/ScreenPocket/Texture/Create")] static void Create() { OpenCreateTextureWindow((w,h,col) => { var icon = EditorGUIUtility.FindTexture("Texture2D Icon"); ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0, new DoCreateTexture() { width = w, height = h, color = col }, "New Texture.png", icon, null); }); } static void OpenCreateTextureWindow(System.Action<int,int,Color> callback) { var w = EditorWindow.GetWindow<CreateTextureInformationWindow>(true, "テクスチャ作成"); w.callback = callback; w.position = new Rect(150f, 150f, 280f, 100f); } public static void Fill(Texture2D texture, Color color ) { for (int y = 0; y < texture.height; ++y) { for (int x = 0; x < texture.width; ++x) { texture.SetPixel(x, y, color); } } texture.Apply(); } } class DoCreateTexture : UnityEditor.ProjectWindowCallback.EndNameEditAction { public int width; public int height; public Color color; public override void Action(int instanceId, string pathName, string resourceFile) { var texture = new Texture2D( width, height ); texture.name = Path.GetFileNameWithoutExtension( pathName ); TextureUtility.Fill( texture, color ); byte[] bytes = texture.EncodeToPNG(); DestroyImmediate( texture ); File.WriteAllBytes(pathName, bytes); AssetDatabase.Refresh(); } } public class CreateTextureInformationWindow : EditorWindow { int w = 0; int h = 0; TextureImporterNPOTScale npotW = TextureImporterNPOTScale.None; TextureImporterNPOTScale npotH = TextureImporterNPOTScale.None; Color color = Color.white; public System.Action<int, int, Color> callback = null; void OnGUI() { EditorGUILayout.BeginHorizontal(); w = EditorGUILayout.IntField(w); EditorGUILayout.LabelField("x", GUILayout.Width(12f)); h = EditorGUILayout.IntField(h); EditorGUILayout.EndHorizontal(); EditorGUILayout.BeginHorizontal(); GUI.enabled = !( Mathf.IsPowerOfTwo(w) ); npotW = (TextureImporterNPOTScale)EditorGUILayout.EnumPopup(npotW); GUI.enabled = !(Mathf.IsPowerOfTwo(h)); npotH = (TextureImporterNPOTScale)EditorGUILayout.EnumPopup(npotH); EditorGUILayout.EndHorizontal(); int finalW = w; int finalH = h; switch (npotW) { case TextureImporterNPOTScale.ToNearest: finalW = Mathf.ClosestPowerOfTwo(finalW); break; case TextureImporterNPOTScale.ToLarger: finalW = Mathf.NextPowerOfTwo(finalW); break; case TextureImporterNPOTScale.ToSmaller: finalW = Mathf.NextPowerOfTwo(finalW)/2; break; } switch (npotH) { case TextureImporterNPOTScale.ToNearest: finalH = Mathf.ClosestPowerOfTwo(finalH); break; case TextureImporterNPOTScale.ToLarger: finalH = Mathf.NextPowerOfTwo(finalH); break; case TextureImporterNPOTScale.ToSmaller: finalH = Mathf.NextPowerOfTwo(finalH)/2; break; } color = EditorGUILayout.ColorField(color); var isValidSize = !(finalW == 0 || finalH == 0); string msg = "サイズが不正なため、テクスチャを作成できません!"; if (isValidSize) { msg = finalW.ToString() + "x" + finalH.ToString() + " のテクスチャを作成します"; } EditorGUILayout.LabelField(msg); GUI.enabled = isValidSize; if (GUILayout.Button("Create")) { if (callback != null) { callback(w,h,color); } Close(); } GUI.enabled = true; } } }
使うときは Projectフォルダを右クリック > ScreenPocket > Texture > Create で、パネルを表示して入力して下さい。
