Unity3D实现多语言切换

项目现在需要做多语言切换部分，下面是一个基本多语言切换实现

1.

首先建立一个类来存放字符，其中包括一个静态方法来根据Key和语言类型获取对应字符

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public static class multiLangConst {

    static Dictionary<string, string> LangMap_en = new Dictionary<string, string>{
        {"txt_name", "Name"},
    };

    static Dictionary<string, string> LangMap_cn = new Dictionary<string, string>{
        {"txt_name", "名字"},
    };

    public static string GetValue(string languageType, string key) {
        if (languageType == "en") {
            return LangMap_en[key];
        } else if (languageType == "cn") {
            return LangMap_cn[key];
        }
        return "N/A";
    }
}

2.

然后建立一个全局的委托

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;

public class GameManager : MonoBehaviour {

    public delegate void OnLanguageChanged(string type);
    public static OnLanguageChanged onLanguageChanged = null;
    public void SetupLanguage(string type) {
        if (onLanguageChanged != null) {
            onLanguageChanged(type);
        }
    }
}

3.

最后是一个Handler，挂在有Text组件的对象上

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class multiLangHandler : MonoBehaviour {

    [SerializeField, Header("Langkey")]
    private string LangKey = "";

    void Awake() {
        GameManager.onLanguageChanged += onLanguageChanged;
    }

    private void OnDestroy() {
        GameManager.onLanguageChanged -= onLanguageChanged;
    }

    void onLanguageChanged(string languageType) {
        Text text = this.gameObject.GetComponent<Text>();
        if (text != null) {
            var value = multiLangConst.GetValue(languageType, LangKey);
            text.text = value;
            return;
        }
    }
}

最后通过按钮来调用GameManager下面的SetupLanguage方法来进行语言切换。
