unity3d meshBaker教程(五) 动态添加删除物体

using UnityEngine;using System.Collections;using System.Collections.Generic;public class EnemyMaker : MonoBehaviour { //我们的水管工人预置 public GameObject prefab; //用来管理敌人的网格 public MB3_MeshBaker meshBaker; //用来记录已经生成的预置 private List<GameObject> prefabs; // Use this for initialization void Awake () { prefabs = new List<GameObject> (); } // Update is called once per frame void Update () { } void OnGUI(){ if(GUI.Button(new Rect(0,0,100,100),'增加预置')){ Vector3 pos = new Vector3(Random.Range(-2,2),1,Random.Range(-2,2)); Quaternion dir = Quaternion.Euler(new Vector3(0,Random.Range(0,360.0f),0)); //生成一个 工人预设 GameObject worker = Instantiate(prefab,pos,dir) as GameObject; GameObject firstMeshRenderer = null; //获取对象身上的所有renderer组件对象 List<GameObject> needAddList= getRenderers(worker,ref firstMeshRenderer); meshBaker.AddDeleteGameObjects(needAddList.ToArray(),null); meshBaker.Apply(); //由于一个物体身上SkinnedMeshRenderer和MeshRenderer一起合并的话不知道为什么人物无法移动， //但是把某个MeshRenderer启用就可以移动了， //不知道是什么原因，如果你知道为什么，请留言~~~谢谢 if(firstMeshRenderer){ firstMeshRenderer.transform.renderer.materials = new Material[0]{}; firstMeshRenderer.transform.renderer.enabled = true; } prefabs.Add(worker); } if(GUI.Button(new Rect(110,0,100,100),'删除第一个')){ if(prefabs.Count>0){ GameObject worker = prefabs[0]; GameObject firstMeshRenderer = null; List<GameObject> needDelList = getRenderers(worker, ref firstMeshRenderer); meshBaker.AddDeleteGameObjects(null,needDelList.ToArray()); meshBaker.Apply(); Destroy(prefabs[0].gameObject); prefabs.RemoveAt(0); } } GUI.Label (new Rect(0,110,200,100),'当前预设数量：' prefabs.Count); } List<GameObject> getRenderers(GameObject obj,ref GameObject firstMeshRenderer){ List<GameObject> needAddList = new List<GameObject>(); SkinnedMeshRenderer[] smrs = obj.GetComponentsInChildren<SkinnedMeshRenderer>(); for (int i = 0; i < smrs.Length; i ) { needAddList.Add(smrs[i].gameObject); } MeshRenderer[] mr = obj.GetComponentsInChildren<MeshRenderer>(); for (int i = 0; i < mr.Length; i ) { if(i == 0){ firstMeshRenderer = mr[i].gameObject; } needAddList.Add(mr[i].gameObject); } return needAddList; }}

核心代码

参数1，需要增加的对象

参数2，需要删除的对象

meshBaker.AddDeleteGameObjects(needAddList.ToArray(),null);
meshBaker.Apply();

Cannot add objects. Resulting mesh will have more than 64k vertices. Try using a Multi-MeshBaker component. This will split the combined mesh into several meshes. You don't have to re-configure the MB2_TextureBaker. Just remove the MB2_MeshBaker component and add a MB2_MultiMeshBaker component.
UnityEngine.Debug:LogError(Object)
DigitalOpus.MB.Co

如果遇到这个报错，使用MB3_MultiMeshBaker替换MB3_MeshBaker

需要创建GameObject->CreateOther->MeshBaker->Multi-Mesh And MaterialBaker 操作和 meshBaker一样

由于一个物体身上SkinnedMeshRenderer和MeshRenderer一起合并的话

不知道为什么人物无法移动，

但是把某个MeshRenderer启用就可以移动了，

不知道是什么原因，如果你知道为什么，请留言~~~谢谢
