如何将相机预设保存到文本文档并在启动时加载？

I need code that would enable me to save my camera's presets and load it at the start or maybe when a GUI button is pressed.

我需要能够保存相机预设的代码,并在开始时或者按下GUI按钮时加载它。

void savePreset()
{
    //Create a txt file or replace own text file and write into it
    using (StreamWriter writetext = new StreamWriter("presets.txt"))
    {
        writetext.Write(player.transform.position.x + ", ");
        writetext.Write(player.transform.position.y + ", ");
        writetext.Write(player.transform.position.z + ", ");
        writetext.Write(player.transform.rotation.w + ", ");
        writetext.Write(player.transform.rotation.x + ", ");
        writetext.Write(player.transform.rotation.y + ", ");
        writetext.Write(player.transform.rotation.z + ", ");
        //Boolean to show that it is still saving
        saving = true;
        writetext.Close();
    }
}

This is a rough idea for saving the code onto a text document. How do I load this info and apply it on my camera?

这是将代码保存到文本文档的粗略想法。如何加载此信息并将其应用到我的相机上?

The best approach might be using PlayPrefs, this way you don't need to care about the path of the setting file, and it is also much faster than saving/loading data to and from the files, as in Mac this is saved to plist, and in windows, saved in registry.

最好的方法可能是使用PlayPrefs,这样你就不需要关心设置文件的路径了,它也比在文件中保存/加载数据快得多,就像在Mac中保存到plist一样,并在Windows中,保存在注册表中。

using UnityEngine;
using System.Collections;

public class Test : MonoBehaviour {

Camera cam;
Transform t;
void Start () {
    cam = Camera.main;
    t = cam.transform;
}
void OnGUI()
{
    if (GUILayout.Button ("Rotate (10,0,0)")) {
        t.Rotate(new Vector3(10,0,0));
        PlayerPrefs.SetFloat("rX", t.rotation.x); // Save
        PlayerPrefs.SetFloat("rY", t.rotation.y);
        PlayerPrefs.SetFloat("rZ", t.rotation.z);
        PlayerPrefs.Save ();                                          
    }
    if (GUILayout.Button ("Reload Camera Euler angle")) {

        var x= PlayerPrefs.GetFloat("rX"); // Load
        var y= PlayerPrefs.GetFloat("rY");
        var z= PlayerPrefs.GetFloat("rZ");
        cam.transform.rotation = Quaternion.Euler(x,y,z);                       
    }
}
}

I've figured it out :D Here's the code for the loadpreset

我已经弄明白了:D这是loadpreset的代码

void loadPreset()
 {
  using (var reader = new StreamReader (File.OpenRead ("presets.txt")))
  {
   //while not end of text file
   while (!reader.EndOfStream) 
   {
    //reading each line
    var line = reader.ReadLine ();
    //dividing into values when "," detected
    var values = line.Split (',');

    //if number of values is 16
    if(values.Length == 7)
    {
     //Save the output value based on it's value position
     if (float.TryParse (values [0], NumberStyles.Float, CultureInfo.InvariantCulture, out tempPos.x)
         && float.TryParse (values [1], NumberStyles.Float, CultureInfo.InvariantCulture, out tempPos.y)
         && float.TryParse (values [2], NumberStyles.Float, CultureInfo.InvariantCulture, out tempPos.z)
         && float.TryParse (values [3], NumberStyles.Float, CultureInfo.InvariantCulture, out tempRot.w)
         && float.TryParse (values [4], NumberStyles.Float, CultureInfo.InvariantCulture, out tempRot.x)
         && float.TryParse (values [5], NumberStyles.Float, CultureInfo.InvariantCulture, out tempRot.y)
         && float.TryParse (values [6], NumberStyles.Float, CultureInfo.InvariantCulture, out tempRot.z)
         )
     {
      //Set the player position and rotation
      player.transform.position = tempPos;
      player.transform.rotation = tempRot;
     }
     else
      continue;
    }
   }
  }
 }

You can use StreamReader to read your txt file.

您可以使用StreamReader读取您的txt文件。

void Load()
{
    using (StreamReader reader = new StreamReader("presets.txt"))
    {
        string[] paras = reader.ReadLine().Split(',');

        Vector3 pos = new Vector3();
        pos.x = float.Parse (paras[0]);
        pos.y = float.Parse (paras[1]);
        pos.z = float.Parse (paras[2]);

        Quaternion q = new Quaternion();
        q.w = float.Parse (paras[3]);
        q.x = float.Parse (paras[4]);
        q.y = float.Parse (paras[5]);
        q.z = float.Parse (paras[6]);

        player.transform.position = pos;
        player.transform.rotation = q;
    }
}
