Unity进阶第四章-UI框架

一、消息框架概述

二、UI框架实现

（1）导入之前的框架，并创建3个新的脚本：UIManager、UIControl、UIController。

UIManager

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class UIManager : ManageBase<UIManager>
{//控制器字典public Dictionary<string, UIController> UIControllerDic = new Dictionary<string, UIController>();//設置頁面激活狀態public void SetActive(string controllerName,bool active){transform.Find(controllerName).gameObject.SetActive(active);}//获取页面上的子控件public UIControl GetUIControl(string controllerName,string controlName){if (UIControllerDic.ContainsKey(controllerName)){//寻找页面中的子控件if (UIControllerDic[controllerName].UIControlDic.ContainsKey(controlName)){return UIControllerDic[controllerName].UIControlDic[controlName];}}return null;}
}

UIControl

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.UI;public class UIControl : MonoBehaviour
{public UIController controller;private void Awake(){//向上层检查，赋值父控制器if (transform.parent != null){controller = transform.GetComponentInParent<UIController>();//将自身控件添加到父控制器中if (controller != null){controller.UIControlDic.Add(transform.name,this);}}}//更改文本public void ChageText(string str){if (GetComponent<Text>() != null){GetComponent<Text>().text = str;}}//更改图片public void ChangeImage(Sprite sprite){if (GetComponent<Image>() != null){GetComponent<Image>().sprite = sprite;}}//按钮public void AddButtonClickEvent(UnityAction action){Button control = GetComponent<Button>();if (control != null){control.onClick.AddListener(action);}}//滑动条public void AddSliderEvent(UnityAction<float> action){Slider control = GetComponent<Slider>();if (control!= null){control.onValueChanged.AddListener(action);}}//InputFieldpublic void InputFieldEvent(UnityAction<string> action){InputField control = GetComponent<InputField>();if (control != null){control.onValueChanged.AddListener(action);}}
}

UIController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class UIController : MonoBehaviour
{public Dictionary<string, UIControl> UIControlDic = new Dictionary<string, UIControl>();void Awake(){//将当前的页面控制器添加到管理器字典中UIManager.Instance.UIControllerDic.Add(transform.name, this);//给子控件添加UIControl脚本foreach(Transform tran in transform){if (tran.gameObject.GetComponent<UIControl>() == null){tran.gameObject.AddComponent<UIControl>();}}}
}

（2）再创建这些脚本挂载到对应的UI上

MainControl：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class MainController : UIController
{// Start is called before the first frame updatevoid Start(){//给按钮添加事件UIManager.Instance.GetUIControl(transform.name,"MenuButton").AddButtonClickEvent(ShowMenu);}void ShowMenu(){UIManager.Instance.SetActive("MenuController", true);gameObject.SetActive(false);}}

StateController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class StateController : UIController
{// Start is called before the first frame updatevoid Start(){UIManager.Instance.GetUIControl(transform.name, "CloseButton (1)").AddButtonClickEvent(Close);}void Close(){UIManager.Instance.SetActive("MenuController", true);gameObject.SetActive(false);}
}

ItemController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ItemController : UIController
{// Start is called before the first frame updatevoid Start(){UIManager.Instance.GetUIControl(transform.name, "CloseButton (2)").AddButtonClickEvent(Close);}// Update is called once per framevoid Close(){UIManager.Instance.SetActive("MenuController",true);gameObject.SetActive(false);}
}

MenuController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class MenuController :UIController
{// Start is called before the first frame updatevoid Start(){UIManager.Instance.GetUIControl(transform.name, "StateButton").AddButtonClickEvent(ShowStateController);UIManager.Instance.GetUIControl(transform.name, "ItemButton").AddButtonClickEvent(ShowItemController);UIManager.Instance.GetUIControl(transform.name, "CloseButton").AddButtonClickEvent(Close);UIManager.Instance.GetUIControl(transform.name, "SkillButton").AddButtonClickEvent(ShowSkillController);}// Update is called once per framevoid ShowStateController(){UIManager.Instance.SetActive("StateController", true);gameObject.SetActive(false);}void ShowItemController(){UIManager.Instance.SetActive("ItemController", true);gameObject.SetActive(false);}void ShowSkillController(){UIManager.Instance.SetActive("SkillController", true);gameObject.SetActive(false);}void Close(){UIManager.Instance.SetActive("MainController", true);gameObject.SetActive(false);}
}

SkillController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SkillController : UIController
{// Start is called before the first frame updatevoid Start(){UIManager.Instance.GetUIControl(transform.name, "Button (Legacy)").AddButtonClickEvent(Close);}// Update is called once per framevoid Close(){UIManager.Instance.SetActive("MenuController",true);gameObject.SetActive(false);}
}

（3）这样就是一个完整的UI框架了
