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 () {
//}
}
