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);
}
}
//InputField
public 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 update
void 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 update
void 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 update
void Start()
{
UIManager.Instance.GetUIControl(transform.name, "CloseButton (2)").AddButtonClickEvent(Close);
}
// Update is called once per frame
void 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 update
void 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 frame
void 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 update
void Start()
{
UIManager.Instance.GetUIControl(transform.name, "Button (Legacy)").AddButtonClickEvent(Close);
}
// Update is called once per frame
void Close()
{
UIManager.Instance.SetActive("MenuController",true);
gameObject.SetActive(false);
}
}
（3）这样就是一个完整的UI框架了
