问题描述

我是 Unity3D 的新手.我正在尝试做一件简单的事情.但无法做到这一点.我有一个 .obj 文件，它是一个 3d 密钥文件.我执行以下操作:

I am new to Unity3D. I am trying to do a simple thing. But not able to do this. I have a .obj file which is a 3d key file. I do the followings:

1. 在 unity3D 中导入此密钥(到资产)
2. 将此键添加到场景(从资产到层次结构)
3. 向该键添加脚本

4. 将 OnMouseDown() 函数添加到此脚本中，如下所示 -

1. Import this key (to assets) in unity3D
2. Add this key to scene (from assets to hierarchy)
3. Add a script to this key

4. Add the OnMouseDown() function to this script as follows -

void OnMouseDown() 
{
    Debug.Log ("clicked...");
}

但是当我单击该键时，控制台中没有显示任何消息.请告诉我是什么问题?

But when I click the key no message is showing in console. Please tell me what is the problem?

推荐答案

1. 确保游戏对象不在忽略光线投射"层

2. 在更新函数中使用以下内容来查看光线投射是否正常工作.

1. make sure the gameobject is not at layer "Ignore Raycast"

2. Use the following inside your update function to see raycasting is working fine.

无效更新(){

if (Input.GetMouseButtonDown (0)) {
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
           RaycastHit hit;
         if (Physics.Raycast(ray, out hit)) {
          Debug.Log ("Name = " + hit.collider.name);
          Debug.Log ("Tag = " + hit.collider.tag);
          Debug.Log ("Hit Point = " + hit.point);
          Debug.Log ("Object position = " + hit.collider.gameObject.transform.position);
          Debug.Log ("--------------");
         }
       }
}
