Unity 3D GridLayoutGroup3D 让子物体对齐，调整子物体间距
效果
GridLayoutGroup3D 脚本是一个用于在 Unity 3D 编辑器中创建 3D 网格布局的实用工具。主要用于在 Unity 编辑器中提供一种可视化的方式来设置和调整子物体的位置，同时支持删除脚本时将物体恢复原位。 源码： #if UNITY_EDITOR using UnityEditor.SceneManagement; #endif using System.Collections.Generic; using UnityEngine; public class GridLayoutGroup3D : MonoBehaviour { #if UNITY_EDITOR public Vector3 matrixInterval = new Vector3(0.25f, 0.25f, 0.25f); public Vector3Int matrixSize = new Vector3Int(3, 3, 3); public Color matrixColor = new Color(255 / 225f, 225 / 225f, 0, 100 / 255f); public float radius = 0.1f; private int ChildIndex = 0; public List locations = new List(); //子物体间隔 public Vector3 MatrixInterval { get => matrixInterval; set { matrixInterval = value; UnityEditor.EditorApplication.QueuePlayerLoopUpdate(); } } //矩阵大小 public Vector3Int MatrixSize { get => matrixSize; set { matrixSize = value; UnityEditor.EditorApplication.QueuePlayerLoopUpdate(); } } public float Radius { get => radius; set { radius = value; UnityEditor.EditorApplication.QueuePlayerLoopUpdate(); } } public Color MatrixColor { get => matrixColor; set { matrixColor = value; UnityEditor.EditorApplication.QueuePlayerLoopUpdate(); } } private void OnDrawGizmosSelected() { DrawAndSetLocation(); } public void DrawAndSetLocation() { ChildIndex = 0; int MatrixSizeX = Mathf.Abs(MatrixSize.x); int MatrixSizeY = Mathf.Abs(MatrixSize.y); int MatrixSizeZ = Mathf.Abs(MatrixSize.z); //刷新子物体位置 for (int j = 0; j for (int i = 0; i if (transform.GetChild(ChildIndex).localPosition != Location) { transform.GetChild(ChildIndex).localPosition = Location; EditorSceneManager.MarkSceneDirty(EditorSceneManager.GetActiveScene()); } } Gizmos.color = MatrixColor; Gizmos.matrix = transform.localToWorldMatrix; Gizmos.DrawCube(Location, Radius * Vector3.one); ChildIndex++; } } } } public void CopyInfo() { if (locations.Count == 0) { foreach (var item in GetComponentsInChildren()) { locations.Add(new Location(item.name, item.position, item.rotation)); } } } public string PasteInfo() { Transform[] transforms = GetComponentsInChildren(); if (transforms.Length != locations.Count) { return "子物体数量不对等！停止赋值！"; } for (int i = 0; i transforms[i].position = locations[i].position; transforms[i].rotation = locations[i].rotation; } else { return "子物体" + locations[i].name + "有变动！停止赋值！"; } } return "赋值成功！"; } public class Location { public string name; public Vector3 position; public Quaternion rotation; public Location(string name, Vector3 position, Quaternion rotation) { this.name = name; this.position = position; this.rotation = rotation; } } #endif } 编辑器扩展（美化面板）记得放到Editor文件夹下 using UnityEditor; using UnityEngine; [CustomEditor(typeof(GridLayoutGroup3D)), CanEditMultipleObjects] public class Editor_GridLayoutGroup3D : Editor { private GridLayoutGroup3D gridLayoutGroup3D; // Start is called before the first frame update private void OnEnable() { gridLayoutGroup3D = target as GridLayoutGroup3D; gridLayoutGroup3D.CopyInfo(); } public override void OnInspectorGUI() { gridLayoutGroup3D.MatrixInterval = EditorGUILayout.Vector3Field("子物体间隔", gridLayoutGroup3D.MatrixInterval); GUILayout.Space(10); gridLayoutGroup3D.MatrixSize = EditorGUILayout.Vector3IntField("矩阵大小", gridLayoutGroup3D.MatrixSize); GUILayout.Space(10); GUILayout.BeginHorizontal(); GUILayout.Label("矩阵显示调节:"); gridLayoutGroup3D.MatrixColor = EditorGUILayout.ColorField(gridLayoutGroup3D.MatrixColor); GUILayout.Space(10); float MaxValue = Mathf.Max(new float[3] { gridLayoutGroup3D.MatrixInterval.x, gridLayoutGroup3D.MatrixInterval.y, gridLayoutGroup3D.MatrixInterval.z }); gridLayoutGroup3D.Radius = EditorGUILayout.Slider(gridLayoutGroup3D.Radius,0.01f, MaxValue/2); GUILayout.EndHorizontal(); if (gridLayoutGroup3D.MatrixSize.y==0|| gridLayoutGroup3D.MatrixSize.x==0|| gridLayoutGroup3D.MatrixSize.z==0) { EditorGUILayout.HelpBox("矩阵大小，最小值为1", MessageType.Info); } GUILayout.Space(10); if (GUILayout.Button("移除并恢复")) { if (EditorUtility.DisplayDialog("警告！", "这将使当前的子物体恢复到开始状态。", "是的", "手滑了~")) { Debug.Log(gridLayoutGroup3D.PasteInfo()); DestroyImmediate(gridLayoutGroup3D); } } } } 代码解释 1. 基本信息 // 使用 UNITY_EDITOR 指令确保这些代码仅在编辑器模式下运行 #if UNITY_EDITOR using UnityEditor.SceneManagement; #endif using System.Collections.Generic; using UnityEngine; public class GridLayoutGroup3D : MonoBehaviour { // ...（省略其他代码） } 在这里，我们通过 #if UNITY_EDITOR 确保包含的代码仅在 Unity 编辑器中运行。 2. 字段和属性 public Vector3 matrixInterval = new Vector3(0.25f, 0.25f, 0.25f); public Vector3Int matrixSize = new Vector3Int(3, 3, 3); public Color matrixColor = new Color(255 / 225f, 225 / 225f, 0, 100 / 255f); public bool isDrawGizmos = true; public float radius = 0.1f; private int ChildIndex = 0; public List locations = new List();这些字段和属性用于在 Unity 编辑器中设置参数。 matrixInterval 是一个三维向量，表示子物体之间的间隔。matrixSize 是一个三维整数向量，表示矩阵的大小。matrixColor 是一个颜色，表示绘制 Gizmos 的颜色。radius 表示 Gizmos 的大小。locations 是一个存储子物体位置信息的列表。 3. 方法 private void OnDrawGizmosSelected() { DrawAndSetLocation(); } public void DrawAndSetLocation() { ChildIndex = 0; int MatrixSizeX = Mathf.Abs(MatrixSize.x); int MatrixSizeY = Mathf.Abs(MatrixSize.y); int MatrixSizeZ = Mathf.Abs(MatrixSize.z); //刷新子物体位置 for (int j = 0; j for (int i = 0; i if (transform.GetChild(ChildIndex).localPosition != Location) { transform.GetChild(ChildIndex).localPosition = Location; EditorSceneManager.MarkSceneDirty(EditorSceneManager.GetActiveScene()); } } Gizmos.color = MatrixColor; Gizmos.matrix = transform.localToWorldMatrix; Gizmos.DrawCube(Location, Radius * Vector3.one); ChildIndex++; } } } } OnDrawGizmosSelected 是 Unity 编辑器中的一个回调方法，用于在选择物体时绘制 Gizmos。DrawAndSetLocation 方法用于刷新子物体的位置并在 Unity 编辑器中绘制 Gizmos。它通过循环遍历矩阵的每个位置，将子物体放置在相应的位置。 4. 位置信息容器 public class Location { public string name; public Vector3 position; public Quaternion rotation; public Location(string name, Vector3 position, Quaternion rotation) { this.name = name; this.position = position; this.rotation = rotation; } }Demo下载地址 |
