Feedback Fed up of poor tile placement in tile palette by Unity ? Here's a fix!

So Unity makes working with 2D tiles a real pain, it just places them all next to each other, making it very difficult to spot and pick ones that are elevated:



I've wrote a small tool that re-distributes them !



Now it's easier to identify and pick them!



Code:

Code (CSharp):

1. using System;
2. using System.Linq;
3. using UnityEditor;
4. using UnityEngine;
5. using UnityEngine.Tilemaps;
6.  
7. namespace z
8. {
9.     internal sealed class TilePaletteAdjuster : EditorWindow
10.     {
11.         [SerializeField]
12.         private int Extent = 10;
13.  
14.         [SerializeField]
15.         private GameObject Prefab;
16.  
17.         [SerializeField]
18.         private bool Square = true;
19.  
20.         [SerializeField]
21.         private int Stride = 3;
22.  
23.         private Tilemap Tilemap => Prefab != null ? Prefab.GetComponentInChildren<Tilemap>() : null;
24.  
25.         [MenuItem("z/Tile Palette Adjuster")]
26.         private static void ShowWindow()
27.         {
28.             var window = GetWindow<TilePaletteAdjuster>(true, "Tile Palette Adjuster", true);
29.             window.minSize = window.maxSize = new Vector2(333.0f, 111.0f);
30.         }
31.  
32.         private void OnGUI()
33.         {
34.             Prefab = EditorGUILayout.ObjectField(new GUIContent("Prefab", "The tile palette to adjust."),
35.                 Prefab, typeof(GameObject), false) as GameObject;
36.  
37.             using (new EditorGUI.DisabledGroupScope(Square))
38.             {
39.                 Extent = EditorGUILayout.IntSlider(
40.                     new GUIContent("Extent", "The extend to distribute tiles on."), Extent, 1, 20);
41.             }
42.  
43.             Stride = EditorGUILayout.IntSlider(
44.                 new GUIContent("Stride", "The stride between each tiles."), Stride, 1, 10);
45.  
46.             Square = EditorGUILayout.Toggle(
47.                 new GUIContent("Square", "Distribute tiles in a square fashion."), Square);
48.  
49.             EditorGUILayout.Space();
50.  
51.             var disabled = Prefab == null ||
52.                            PrefabUtility.GetPrefabAssetType(Prefab) != PrefabAssetType.Regular ||
53.                            Tilemap == null;
54.  
55.             using (new EditorGUILayout.HorizontalScope())
56.             using (new EditorGUI.DisabledGroupScope(disabled))
57.             {
58.                 GUILayout.FlexibleSpace();
59.  
60.                 if (GUILayout.Button("Adjust", GUILayout.Width(75.0f)))
61.                     Adjust();
62.             }
63.         }
64.  
65.         private void Adjust()
66.         {
67.             var tilemap = Tilemap;
68.             if (tilemap is null)
69.                 throw new ArgumentNullException(nameof(tilemap));
70.  
71.             var block = tilemap.GetTilesBlock(tilemap.cellBounds);
72.             var tiles = block.Where(s => s != null).OrderBy(s => s.name).ToArray();
73.             var ceil = (int) Mathf.Ceil(Mathf.Sqrt(tiles.Length));
74.             var w = Square ? ceil : Extent;
75.             var h = Square ? ceil : tiles.Length / Extent + (tiles.Length % Extent == 0 ? 0 : 1);
76.             var z = tilemap.cellBounds.size.z;
77.  
78.             var array = new TileBase[w * Stride * h * Stride];
79.             var index = 0;
80.  
81.             foreach (var tile in tiles)
82.             {
83.                 var x = index % w * Stride;
84.                 var y = index / w * Stride;
85.                 var i = y * w * Stride + x;
86.                 array[i] = tile;
87.                 index++;
88.             }
89.  
90.             // if we save asset we lose undo, but then preview in Tile Palette fails, this hack allows both
91.             Selection.activeObject = Prefab;
92.  
93.             Undo.RecordObject(tilemap, "Adjust Tile Palette");
94.  
95.             tilemap.ClearAllTiles();
96.             tilemap.size = new Vector3Int(w * Stride, h * Stride, z);
97.             tilemap.SetTilesBlock(tilemap.cellBounds, array);
98.  
99.             PrefabUtility.RecordPrefabInstancePropertyModifications(tilemap);
100.             EditorUtility.SetDirty(Prefab);
101.         }
102.     }
103. }

Hope that'll ring some bell at Unity ...

Comment and share your improvements!

 

I think this is nice because you can have both spaced out tiles and adjacent tiles, but to get the visual results in your screenshot, you could increase the gap value of the palette asset's grid component I believe.

 

haven't thought about that, really clever!



it's even more clear as on where the content is supposed to sit in the tile.

Thanks

 

Literally stumbled across this today after my tile frustration was boiling over... an absolute god-send - can't thank you enough!!!!
