Unity编辑模式下创建若干子物体父物体
发表于2018-10-29
在unity编辑模式下，想要创建若干个物体并且标注谁的谁的子物体，谁是谁的父物体该怎么办，下面就给大家介绍下实现方法，步骤如下：
1、首先使用脚本创建空物体，在菜单中显示出来
using UnityEngine;
using System.Collections;
public class PathNode : MonoBehaviour ｛
public PathNode m_parent;
public PathNode m_next;
public void setNext(PathNode node)｛
if(m_next!=null) m_next.m_parent=null;
m_next=node;
node.m_parent=this;
｝
// 显示图标
void OnDrawGizmos()｛
Gizmos.DrawIcon(this.transform.position,"Node.tif");
｝
｝
2、设置每个物体的层级关系
using UnityEngine;
using System.Collections;
using UnityEditor;
public class PathTool : ScriptableObject ｛
//父路点
static PathNode m_parent = null;
static int num = 0;
[MenuItem("PathTools/Create PathNode")]
static void CreatePathNode() ｛
GameObject go = new GameObject();
go.AddComponent<PathNode>();
go.name = "pathnode"+num++;
go.tag = "pathnode";
Selection.activeTransform = go.transform;
｝
[MenuItem("PathTools/set Parent %q")]
static void SetParent() ｛
if (!Selection.activeObject || Selection.GetTransforms(SelectionMode.Unfiltered).Length > 1) return;//编辑状态下没有选中物体
if (Selection.activeGameObject.tag.CompareTo("pathnode") == 0) ｛
m_parent = Selection.activeGameObject.GetComponent<PathNode>();
｝
｝
[MenuItem("PathTools/Set Child %w")]
static void setChild() ｛
if (!Selection.activeGameObject || Selection.GetTransforms(SelectionMode.Unfiltered).Length > 1) return;
if (Selection.activeGameObject.tag.CompareTo("pathnode") == 0) ｛
if (m_parent == null) ｛
Debug.LogError("先设置子节点");
return;
｝
m_parent.setNext(Selection.activeGameObject.GetComponent<PathNode>());//父节点上面保存了， 将当前的节点作为上一个父节点的子节点
m_parent = null;
｝
｝
｝
