现在的UGUI使用非常的广泛,使用UGUI可以方便快速地建立UI界面,下面要和大家介绍的是侧面滑出的菜单栏的创建以及宽度自适应设置,一起来看看吧。

首先看下项目效果

实现效果

发现实现效果并不难,利用动画(iTween)+UGUI 有一个长按的判断处理即可
附上项目和代码
using System.Collections;  
using System.Collections.Generic;  
using UnityEngine;  
using UnityEngine.UI;  
public class UICont : MonoBehaviour {  
    public RectTransform mainUI;  
    public Button showHideBtn;  
    public RepeatButton dragBtn;  
    private bool m_isShow = true;  
   // public RectTransform   
    // Use this for initialization  
    void Start () {  
        dragBtn.onPress.AddListener(DragBtn);  
        showHideBtn.onClick.AddListener(ShowHide);  
    }  
    void ShowHide() {  
        Vector3 vec3Tmp = mainUI.position;  
        if(m_isShow) {  
            vec3Tmp.x = -mainUI.sizeDelta.x;  
            iTween.MoveTo(mainUI.gameObject, vec3Tmp, 1f);  
            m_isShow = false;  
        } else {  
            vec3Tmp.x = 0;  
            iTween.MoveTo(mainUI.gameObject, vec3Tmp, 1f);  
            m_isShow = true;  
        }  
    }  
    void DragBtn() {  
        Vector2 vec2Tmp = mainUI.sizeDelta;  
        vec2Tmp.x = Mathf.Clamp(Input.mousePosition.x, 100, 500);  
        mainUI.sizeDelta = vec2Tmp;  
    }  
    // Update is called once per frame  
    //void Update () {  
    //}  
}
