It's well worth noting that if you just want to send a very simple one with NO dynamic text, no body, no unusual characters, just replace the spaces with %20 manually like so:

public void LinkHelpEMAIL()
  {
  string t =
  "mailto:blah@blah.com?subject=Question%20on%20Awesome%20Game";
  Application.OpenURL(t);
  }
exactly like that (do not escape the at symbol). saves typing, tested on both.

生成脚本

编辑器脚本可以通过

var scriptPath = AssetDatabase.GetAssetPath(MonoScript.FromScriptableObject(this));

AssetDatabase.LoadAssetAtPath<TextAsset>(assetPath);

inputText.Replace

File.WriteAllText(writePath, inputText);

AssetDatabase.SaveAssets();

AssetDatabase.Refresh();

物体 transform.rotation.eulerAngles; 遇到万向锁了 transform.forward 向前则没有，赋值给主角朝向

设置一下Lua脚本的模板地址： Assets/Editor/Lua/Template/lua.lua

using UnityEngine;

using UnityEditor;

using System;

using System.IO;

using System.Text;

using UnityEditor.ProjectWindowCallback;

using System.Text.RegularExpressions;

public class Test

{

[MenuItem("Assets/Create/Lua Script", false, 80)]

public static void CreatNewLua()

{

初级资源创建

Editor文件夹下创建脚本：

using UnityEngine;

using UnityEditor;

public class CreateTest

{

[MenuItem ("Assets/Create ExampleAssets")]

static void CreateExampleAssets ()

{

var material = new Material (Shader.Find ("Standard"));

ProjectWindowUtil.CreateAsset (material, "New Material.mat");

}

点击Assets－－Create ExampleAssets 就会发现一个材质球被创建

中级资源创建

Editor文件夹下创建脚本：

using UnityEngine;

using UnityEditor;

public class CreateMaterial

{

[MenuItem ("Assets/Create Material")]

static void CreateExampleAssets ()

{

var material = new Material (Shader.Find ("Standard"));

var instanceID = material.GetInstanceID ();

var icon = AssetPreview.GetMiniThumbnail (material);

var endNameEditAction =

ScriptableObject.CreateInstance<DoCreateMaterialAsset> ();

ProjectWindowUtil.StartNameEditingIfProjectWindowExists (instanceID,

endNameEditAction, "New Material.mat", icon, "");

}

点击Assets－－Create Material 创建一个特定的材质球

更自由的自定义资源创建

Editor文件夹下创建脚本：

using UnityEngine;

using UnityEditor;

using UnityEditor.ProjectWindowCallback;

public class DoCreateMaterialAsset : EndNameEditAction

{

public override void Action (int instanceId, string pathName, string resourceFile)

{

var mat = (Material)EditorUtility.InstanceIDToObject (instanceId);

mat.color = Color.red;

AssetDatabase.CreateAsset (mat, pathName);

AssetDatabase.ImportAsset (pathName);

ProjectWindowUtil.ShowCreatedAsset (mat);

}

Editor文件夹下创建脚本：

using System.IO;

using System.Text;

using UnityEditor;

using UnityEditor.ProjectWindowCallback;

using System;

public class DoCreateScriptAsset : EndNameEditAction

{

public override void Action (int instanceId, string pathName, string resourceFile)

{

var text = File.ReadAllText (resourceFile);

var className = Path.GetFileNameWithoutExtension (pathName);

//清除空格

className = className.Replace (" ", "");

text ="//Programer: "+"porgramerName"+"\n//code date:"+DateTime.Now.Date.ToShortDateString()+"\n"

+text.Replace ("#SCRIPTNAME#", className);

text += "\n//自己添加Something！"+"\n";

//utf8

var encoding = new UTF8Encoding (true, false);

File.WriteAllText (pathName, text, encoding);

AssetDatabase.ImportAsset (pathName);

var asset = AssetDatabase.LoadAssetAtPath<MonoScript> (pathName);

ProjectWindowUtil.ShowCreatedAsset (asset);

}

Editor文件夹下创建脚本：

using UnityEditor;

using UnityEngine;

using System.IO;

public class CreateAssets : EditorWindow

{

[MenuItem("Window/CreatAssets")]

static void Open ()

{

GetWindow<CreateAssets> ();

}

public string scriptName,materialName;

/// 3D世界坐标转2DUI坐标并自适应的做法（血条，气泡）

UI
屏幕坐标系是从左下角为原点，Y轴向右为正，X轴向上为正。所有相关的UI的锚点都需要是设置成左下为锚点。其次，UI挂载的根节点需要做屏幕的自适应，保证和屏幕一样大。

脚本
常见的情况下有两种宽高。只要不是PC的固定界面大小，屏幕大小和设置的界面大小就会有对应的缩放情况。

第一种情况
Canvas使用固定屏幕大小。这种情况无论真机比例如何，都会按照预先设置好的大小比例进行缩放。

因为没有跟随屏幕分辨率进行缩放，所以我们在计算后需要再做多一步进行转换。根节点要做自适应。width和Height是屏幕宽高，位置是中心点（宽高/2）。

父节点的大小设置

PlaneTransform.sizeDelta = CanvanTransform.sizeDelta;
PlaneTransform.anchoredPosition = PlaneTransform.sizeDelta / 2;

UI的位置需要转化一下

Vector3 pos = Camera.main.WorldToScreenPoint(m_TragetTransform.position + m_Offect);
pos.x *= m_CanvasTransform.sizeDelta.x / Screen.width;
pos.y *= m_CanvasTransform.sizeDelta.y / Screen.height;
pos.z = 0;
m_MyTransform.anchoredPosition = pos;

第二种情况
Canvas跟随屏幕大小，这样会跟随着分辨率的改变而改变。
因为根节点已经做了转换，所以直接设置即可。

//m_TragetTransform是模型对象
Vector3 pos = Camera.main.WorldToScreenPoint(m_TragetTransform.position + m_Offect);
pos.z = 0;
m_MyTransform.anchoredPosition = pos;
