带动态插入效果的排行榜

Posted 2020-12-29 llstart-new0201

最近有需求做一个排行榜，需要根据某一参数大小插入到排行榜中，但是要有一个插入后后续榜单元素下移的效果。代码如下：

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

public class DynamicChange : MonoBehaviour
{
    public GameObject container;
    public GameObject elem;
    public InputField input;

    public float deltaH = 110;

    public float movieTime = 0.5f;
    float deltaTime = 0.1f / 5;
    float movedDeltaH = 110 / 5;
    float speed = 3;

    public void Insert()
    {
        int location = int.Parse(input.text);//插入元素的位置

        List<GameObject> childList = new List<GameObject>();
        foreach (Transform t in container.transform)
        {
            childList.Add(t.gameObject);
        }

        Vector2 anchorPos = childList[location].GetComponent<RectTransform>().anchoredPosition;//插入元素的位置坐标

        container.GetComponent<VerticalLayoutGroup>().enabled = false;

        GameObject eleInst = Instantiate(elem, container.transform);
        eleInst.GetComponent<Image>().color = Color.black;
        eleInst.transform.SetSiblingIndex(location);
        eleInst.GetComponent<RectTransform>().anchoredPosition = anchorPos;//实例化出插入的元素并赋值相关参数
        //eleInst.GetComponent<RectTransform>().anchoredPosition = new Vector2(0,-deltaH*location);


        StartCoroutine(DoMoveMovie(childList.GetRange(location,childList.Count-location)));//后续元素下移效果

        //eleInst.transform.SetSiblingIndex(location);
    }

    IEnumerator DoMoveMovie(List<GameObject> movedGo)//通过协程把瞬间位置的变化改为渐变的过程
    {
        for(int i=0;i<5;i++)
        {
            foreach (GameObject go in movedGo)
            {
                Vector2 pos = go.GetComponent<RectTransform>().anchoredPosition;
                go.GetComponent<RectTransform>().anchoredPosition = new Vector2(pos.x, pos.y - movedDeltaH);
            }

            yield return new WaitForSeconds(speed*Time.deltaTime);
        }
        Destroy(movedGo[movedGo.Count - 1]);
    }
}
