在运行时将.OBJ加载到Unity中 [英] Loading a .OBJ into Unity at runtime

问题描述

我的工作是编写代码，以便在运行时将.OBJ加载到Unity中. Unity在 Wiki 页面中提供了示例代码.我使用以下代码来使用链接中给出的类:

My job is to write a code which loads a .OBJ into Unity in runtime. Unity has provided a sample code in it's wiki page. I used the following code to use the class given in the link:

public class Main : MonoBehaviour {

    // Use this for initialization
    void Start () {
        Mesh holderMesh = new Mesh ();
        ObjImporter newMesh = new ObjImporter();
        holderMesh = newMesh.ImportFile("C:/Users/cvpa2/Desktop/ng/output.obj");
    }

我在Unity Monodevelop中没有收到任何错误，但是没有加载任何模型. 可能是什么解决方案?

I'm not getting any errors in Unity Monodevelop, but neither is the model loaded. What may be the probable solution?

推荐答案

仅创建Mesh对象是不够的.您将至少还要做两件事:

Just creating a Mesh object is not enough. You will have to do at least two more things:

• 创建一个MeshRenderer组件
• 创建一个MeshFilter组件

因此，如果将代码更改为以下代码，则至少应看到网格(如果已成功创建).

So if you change your code to the following you should at least see your mesh if it has been successfully created.

using UnityEngine;
using System.Collections;

public class Main : MonoBehaviour
{

    // Use this for initialization
    void Start()
    {
        Mesh holderMesh = new Mesh();
        ObjImporter newMesh = new ObjImporter();
        holderMesh = newMesh.ImportFile("C:/Users/cvpa2/Desktop/ng/output.obj");

        MeshRenderer renderer = gameObject.AddComponent<MeshRenderer>();
        MeshFilter filter = gameObject.AddComponent<MeshFilter>();
        filter.mesh = holderMesh;
    }
}

从那里开始，您仍然必须分配材料(如果已加载/创建)和其他类似的东西，但这只是一个开始.

From there on out you'd still have to assign a material (if loaded/created) and other such things, but it would be a start.
