多语言切换
unity实现多语言切换就需要有类似与语言包一样的东西，这里我将语言包整成Txt文本的形式存放，大家也可以转换成其他形式存储。
在脚本中有个Init方法是用于初始化语言包信息的只有调用了Init方法调用程序中的其他方法才有效。
init方法可重复调用。
调用Init方法时需要传递参数Language结构的内容。
Language结构
Language结构中的m_Type为语言类型为必须传递的参数。
Language结构中的语言文本有三种，只需传递一种就可以。
语言文本中形成 Text Key = [Value] 格式为有效的文本格式且文本格式必须在同一行内方为有效.
格式中的Key值只能由《 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_ 》组成且Key中不能由空格存在。
格式中的Value值得存在必须写在中括号里面
public struct Language{/// <summary>/// 语言类型/// </summary>public LanguageType m_Type;/// <summary>/// 语言文本/// </summary>public TextAsset m_Txt;/// <summary>/// 语言文本/// </summary>public byte[] bytes;/// <summary>/// 语言文本/// </summary>public string text;}
Demo
下面是写在Chinese.txt中得内容
Text Home_Title_00 = [首页]Text Home_Title_01 = [登陆]Text Home_Title_02 = [退出]
下面是写在English.txt中得内容
Text Home_Title_00 = [Home]Text Home_Title_01 = [Login]Text Home_Title_02 = [Exit]
在两个文本中写有相同得key组成得语言库就可在实现语言切换
将需要实现语言切换得方法添加进切换语言回调中即可
调用Add方法即可添加语言切换回调。
调用Setting_LanguageType方法即可切换当前语言形式，切换成功会调用已添加回调。
在回调中重新调用GetValueToKey方法即可实现语言切换。
完整代码中的 ValueToKey 由样式
下面为初始化语言的Demo
TextAsset chinese;//中文语言上文中的chinese.txtTextAsset english;//英文语言上文中的english.txtprivate void Awake(){//初始化语言包LanguageManager.GetManager.Init(new Language{m_Type = LanguageType.Chinese,m_Txt = chinese,},new Language{m_Type = LanguageType.English,m_Txt = english,});}
完整的代码
ValueToKey获取语言得帮助脚本将其挂载在Text或TextMesh上，然后填写Key得值即可配合LanguageManager一起使用。
[AddComponentMenu("UI/TextValue")]public class ValueToKey : MonoBehaviour{[SerializeField]private string Key;public string GetKey {get {return Key; } }/// <summary>/// /// </summary>public Text m_Content;public TextMesh m_Content_3D;private void Awake(){LanguageManager.GetManager.Add(GetValueToKey);m_Content_3D = this.transform.GetComponent<TextMesh>();if (m_Centent == null)if (m_Content == null)m_Content = this.transform.GetComponent<Text>();GetValueToKey();}/// <summary>/// 设置Key值并更新Value/// </summary>/// <param name="varKey"></param>public void SettingKey(string varKey){Key = varKey;GetValueToKey();}private void OnEnable(){if (!string.IsNullOrEmpty(Key)){GetValueToKey();}}private void GetValueToKey(){string Value = LanguageManager.GetManager.GetValueToKey(Key);if (m_Content != null)m_Content.text = Value;if (m_Content_3D != null)m_Content_3D.text = Value;}}
LanguageManager多语言切换得关键性脚本

该方法在读取解析文本时优先考虑TextAsset、其次时byte[]、最后考虑string类型，实现动态加载就看你是使用什么方式去加载等到文本的内容，只要在调用LanguageManager.Init方法时将语言文本传入即可使用LanguageManager的GetValueToKey方法来获取值信息，从而实现动态加载文字。
