使用框架前置条件：调整脚本运行顺序, Canvas挂载UIManager, Panel挂载对应的UIController、UI控件挂载UIControl。
UIManager:UI管理器，用于处理和管理各个UIController和UIControl的业务逻辑，挂载在Canvas上；
UIController:界面层Controller，用于管理该界面下的所有控件信息；
UIControl：控件层Control，用于管理对应的组件信息。
UIManager：
public class UIManager3 : MonoBehaviour
{
private static UIManager3 instance;
public static UIManager3 Instance { get => instance; }
private Dictionary<string, UIController3> uiControllerList = new();
public virtual void Awake()
{
instance = this;
}
public virtual void OnDestroy()
{
uiControllerList.Clear();
Destroy(this);
}
public void AddToList(string uiControllerName, UIController3 uiController3)
{
if (!uiControllerList.ContainsKey(uiControllerName))
uiControllerList.Add(uiControllerName, uiController3);
}
public void LogoutUIController(string name)
{
if (uiControllerList.ContainsKey(name))
uiControllerList.Remove(name);
}
public void SetControllerActive(string uiControllerName, bool active)
{
foreach(Transform trans in transform)
{
if (trans.name == uiControllerName) trans.gameObject.SetActive(active);
}
}
public UIController3 GetUIController(string name)
{
if (uiControllerList.TryGetValue(name, out UIController3 uiController3))
return uiController3;
return null;
}
public UIControl3 GetUIControl(string controllerName, string controlName)
{
if (uiControllerList.TryGetValue(controllerName, out UIController3 uiController3))
return uiController3.GetUIControl(controlName);
return null;
}
}
UIController：
public abstract class UIController3 : MonoBehaviour
{
private Dictionary<string, UIControl3> uiControlList = new();
public virtual void Start()
{
UIManager3.Instance.AddToList(this.name, this);
foreach(Transform trans in transform)
{
if (trans.gameObject.GetComponent<UIControl>() != null) Destroy(trans.gameObject.GetComponent<UIControl>());
trans.gameObject.AddComponent<UIControl3>();
}
}
public virtual void OnDestroy()
{
UIManager3.Instance.LogoutUIController(this.name);
Destroy(this);
}
public UIControl3 GetUIControl(string name)
{
if (uiControlList.TryGetValue(name, out UIControl3 uiControl3))
return uiControl3;
return null;
}
public void LogoutUIControl(string name)
{
if (uiControlList.ContainsKey(name))
uiControlList.Remove(name);
}
}
UIControl：
public class UIControl3 : MonoBehaviour
{
private UIController3 parentController;
public virtual void Start()
{
if (transform.parent.GetComponentInParent<UIController3>() != null) parentController = transform.parent.GetComponentInParent<UIController3>();
}
public virtual void OnDestroy()
{
parentController.LogoutUIControl(this.name);
Destroy(this);
}
public void SetText(string txt)
{
if (GetComponent<Text>() != null)
GetComponent<Text>().text = txt;
}
public void SetButtonOnClick(UnityAction unityAction)
{
if (GetComponent<Button>() != null)
GetComponent<Button>().onClick.AddListener(unityAction);
}
public void SetSliderEvent(UnityAction<float> unityAction)
{
if (GetComponent<Slider>() != null)
GetComponent<Slider>().onValueChanged.AddListener(unityAction);//unityAction(float), float为Slider改变后的value值
}
public void SetImage(Sprite sprite)
{
if (GetComponent<Image>() != null)
GetComponent<Image>().sprite = sprite;
}
public void SetInpueFieldEvent(UnityAction<string> unityAction)
{
if (GetComponent<InputField>() != null)
GetComponent<InputField>().onValueChanged.AddListener(unityAction);//unityAction(string), string为InputField的整个文本
}
}
LoginPanel（GameObject名称为“Login_Panel”）：
public class LoginPanel3 : UIController3
{
public Button UI_LoginBtn;
public override void Start()
{
base.Start();
UI_LoginBtn.GetComponent<Button>().onClick.AddListener(UILoginBtnOnClick);
}
private void UILoginBtnOnClick()
{
UIManager3.Instance.SetControllerActive(this.name, false);
UIManager3.Instance.SetControllerActive("Main_Panel", true);
}
}
MainPanel（GameObject名称为“Main_Panel”）：
public class MainPanel3 : UIController3
{
public Button UI_ToMenuBtn;
public Button UI_LogoutBtn;
public override void Start()
{
base.Start();
UI_ToMenuBtn.GetComponent<UIControl3>().SetButtonOnClick(UITOMenuBtnOnClick);
UI_LogoutBtn.GetComponent<UIControl3>().SetButtonOnClick(UILogoutBtnOnClick);
}
private void UITOMenuBtnOnClick()
{
UIManager3.Instance.SetControllerActive(this.name, false);
UIManager3.Instance.SetControllerActive("Menu_Panel", true);
}
private void UILogoutBtnOnClick()
{
UIManager3.Instance.SetControllerActive(this.name, false);
UIManager3.Instance.SetControllerActive("Login_Panel", true);
}
}
MenuPanel（GameObject名称为“Menu_Panel”）：
public class MenuPanel3 : UIController3
{
public Button UI_TOMainBtn;
public override void Start()
{
base.Start();
UI_TOMainBtn.GetComponent<UIControl3>().SetButtonOnClick(UITOMainBtnOnClick);
}
private void UITOMainBtnOnClick()
{
UIManager3.Instance.SetControllerActive(this.name, false);
UIManager3.Instance.SetControllerActive("Main_Panel", true);
}
}
