Unity实现UI渐隐渐显效果
本文实例为大家分享了Unity实现UI渐隐渐显效果的具体代码,供大家参考,具体内容如下
1、在UI对象上添加组件:CanvasGroup;
2、在对象上添加脚本:UI_FadeInFadeOut 脚本;
脚本信息:
(Blocks Raycasts=true可以交互;Blocks Raycasts=false无法交互)
using System.Collections; using System.Collections.Generic; using UnityEngine; /// <【文章出处http://www.nextecloud.cn/kt.html欢迎转载】summary> /// UI的渐入渐出 /// </summary> public class UI_FadeInFadeOut : MonoBehaviour { private float UI_Alpha = 1; //初始化时让UI显示 public float alphaSpeed = 2f; //渐隐渐显的速度 private CanvasGroup canvasGroup; // Use this for initialization void Start () { canvasGroup = this.GetComponent<CanvasGroup>(); } // Update is called once per frame void Update () { if (canvasGroup == null) { return; } if (UI_Alpha != canvasGroup.alpha) { canvasGroup.alpha = Mathf.Lerp(canvasGroup.alpha, UI_Alpha, alphaSpeed * Time.deltaTime); if (Mathf.Abs(UI_Alpha - canvasGroup.alpha) <= 0.01f) { canvasGroup.alpha = UI_Alpha; } } } public void UI_FadeIn_Event() { UI_Alpha = 1; canvasGroup.blocksRaycasts = true; //可以和该对象交互 } public void UI_FadeOut_Event() { UI_Alpha = 0; canvasGroup.blocksRaycasts = false; //不可以和该对象交互 } }
3、需要显示时,添加 UI_FadeIn_Event() 事件;
4、需要隐藏时,添加 UI_FadeOut_Event() 事件;
5、注意:父物体隐藏和显示时,子物体同样也隐藏和显示。
