通过实例化对象上的脚本旋转对象 [英] Rotate object through script on Instantiate object

问题描述

我正在通过脚本在特定坐标(x，y，z)实例化对象，然后我想在特定坐标(x，y，z)处旋转对象. 这是我的代码，但是没有旋转

I am Instantiating object through script at specific coordinates(x,y,z), and after that i want to rotate it at specific coordinates(x,y,z). here is my code but it doesn't rotating

using UnityEngine;
using System.Collections;
public class Generator : MonoBehaviour {
public GameObject fire;
//public GameObject firetaps;
//System.Random randomize = new System.Random();
// Use this for initialization
void Start () {
    //int fun=randomize.Next(1,6);
    switch (1) {
    case 1:
        PlaceFire();
        break;
    /*case 2:
        PlaceFire1 ();
        break;
    case 3:
        PlaceFire2 ();
        break;*/
      }
     }
    void PlaceFire()
    {
    Instantiate(fire, GeneratedPosition(), Quaternion.identity);
fire.transform.eulerAngles = new Vector3         (275.0941f,287.0612f,72.63131f);// it does not rotate :-(
    //fire.transform.Rotate(275.0941f,287.0612f,72.63131f);
}
Vector3 GeneratedPosition()
{
    float x,y,z;
    x = -142.5f;
    y = 39.165f;
    z =9.9817f;
    return new Vector3(x,y,z);
}

推荐答案

您需要将Instantiate的返回值存储在您的fire字段中.您从未旋转实例化的游戏对象. (另请阅读修改内容！)

You would need to store the return value of Instantiate in your fire field. You never rotated the instantiated gameobject. (also read the edit!!)

Instantiate(fire, GeneratedPosition(), Quaternion.identity);
fire.transform.eulerAngles = new Vector3(275.0941f,287.0612f,72.63131f);

应该是

fire = Instantiate(fire, GeneratedPosition(), Quaternion.identity) as GameObject;
fire.transform.eulerAngles = new Vector3(275.0941f,287.0612f,72.63131f);

你的魔法值也是奇怪的.

also your magic values are odd.

修改 我只是意识到火是你的预制件.因此，您可能要使用局部变量.

edit I just realized fire is your prefab. So you might want to use a local variable instead.

GameObject fireInstance = Instantiate(fire, GeneratedPosition(), Quaternion.identity) as GameObject;
fireInstance.transform.eulerAngles = new Vector3(275.0941f,287.0612f,72.63131f);

Instantiate重载的第三个参数已经旋转了，那么为什么不立即将其传递到那里呢?

Also the 3rd argument of this overload of Instantiate takes a rotation already, so why not pass it there right away?

Instantiate(fire, GeneratedPosition(), Qaternion.Euler(275.0941f,287.0612f,72.63131f));

Idk是否仍然需要参考，则视情况而定.但是请注意，它仅返回需要转换为所需类型的对象.

Idk if you would still need a reference then, depends. But note how it only returns object you will need to cast to the desired type.
