unity 手柄控制按钮切换显示的通用方法

在UI的基类内放入下面的代码

public void BaseUpdate()
{
if (isGameClick && Manager.isShowGuid)
{
return;
}
if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.LUp, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.LUp, 1) || Input.GetKeyDown(KeyCode.W))
{
//上
Vertical_Click(-1);
Debug.Log("XBoxClick.DPadHorizontal2" + "-1");
}
if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.LDown, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.LDown, 1) || Input.GetKeyDown(KeyCode.S))
{
//下
Vertical_Click(1);
Debug.Log("XBoxClick.DPadHorizontal2" + 1);
}
if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.LLeft, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.LLeft, 1) || Input.GetKeyDown(KeyCode.A))
{
//左
Horizontal_Click(-1);
Debug.Log("XBoxClick.RightStickVertical" + "-1");
}
if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.LRight, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.LRight, 1) || Input.GetKeyDown(KeyCode.D))
{
//右
Horizontal_Click(1);
Debug.Log("XBoxClick.RightStickVertical" + "-1");
}

if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.A, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.A, 1) || Input.GetKeyDown(KeyCode.Q))
{
//A键
Debug.Log("Update" + "-1");
Sure_Click();
}

if (ControllerManager.Instance.GetKeyDown(XboxControllerKey.B, 0) || ControllerManager.Instance.GetKeyDown(XboxControllerKey.B, 1) || Input.GetKeyDown(KeyCode.Space))
{
//B键
Back_Click();
}
if (isAllowClick)
{
clickTime += Time.deltaTime;
if (clickTime > 0.2)
{
isAllowClick = false;
clickTime = 0;
}
}
}

[HideInInspector]
//横向选择
public int h_Index = 0;
[HideInInspector]
//纵向选择
public int v_Index = 0;

public List<List<Button>> buttons = new List<List<Button>>();

public bool isAllowClick = false;
//[HideInInspector]
public bool isGameClick = false;
float clickTime = 0;

//选中的下标横向变换
public virtual void Horizontal_Click(int num)

}

//将选中标志高亮的图显示出来

//需要自己添加高亮图，改名
btns[j].transform.Find("ClickDown").gameObject.SetActive(isShow);
}
}
}

//确认

public virtual void Sure_Click()
{

{//防止连击
return;
}

{
selectBtn.onClick.Invoke();
}
}

//返回键

public virtual void Back_Click()

}

}

将下面代码放入UI的子类

//将要控制显示的按钮

public List<Button> buttons1 = new List<Button>();

public List<Button> buttons2 = new List<Button>();

public List<Button> buttons3 = new List<Button>();

public List<Button> buttons4 = new List<Button>();
