如何为统一应用创建动态边栏（菜单）

Question

我想为我的AR Unity应用程序创建一个侧边栏（如android中的导航抽屉），当我触摸屏幕的左边框并向右拖动时，侧边栏应显示带有按钮列表，如（关于我们的设置）。 。）。

我很快就鞭打了。这应该可以帮助您入门。

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

public class SlidePanel : MonoBehaviour
{

    //Process touch for panel display on if the touch is less than this threshold.
    private float leftEdge = Screen.width * 0.25f;

    //Minimum swipe distance for showing/hiding the panel.
    float swipeDistance = 10f;


    float startXPos;
    bool processTouch = false;
    bool isExpanded = false;
    public Animation panelAnimation;



    void Update(){
        if(Input.touches.Length>0)
            Panel(Input.GetTouch(0));
    }




    void Panel (Touch touch)
    {
        switch (touch.phase) {
        case TouchPhase.Began:
            //Get the start position of touch.

            startXPos = touch.position.x;
            Debug.Log(startXPos);
            //Check if we need to process this touch for showing panel.
            if (startXPos < leftEdge) {
                processTouch = true;
            }
            break;
        case TouchPhase.Ended:
            if (processTouch) {
                //Determine how far the finger was swiped.
                float deltaX = touch.position.x - startXPos;


                if(isExpanded && deltaX < (-swipeDistance))
                {

                    panelAnimation.CrossFade("SlideOut");
                    isExpanded = false;
                } 
                else if(!isExpanded && deltaX > swipeDistance) 
                {
                    panelAnimation.CrossFade("SlideIn");
                    isExpanded = true;
                }

                startXPos = 0f;
                processTouch = false;
            }
            break;
        default:
            return;
        }
    }
}

Answer 2

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

public class ToggleInfo : MonoBehaviour
{

public GameObject panel;
int counter;

public void toggle()
{
    counter++;
    if(counter%2==1)
    {
        panel.gameObject.SetActive(false);
    }
    else
    {
        panel.gameObject.SetActive(true);
    }
  }
}

1. 请确保检查器中面板的名称为'panel'，并且其名称为最初禁用。

2。将此脚本附加到按钮上，然后将您的'panel'拖动到检查器面板中该脚本的公共游戏对象中。

3。通过单击按钮调用toggle功能。
