unity 开发实现滑动移动固定距离

这里以小时为例展示

public void OnScrollValueChanged(Vector2 v)
{
if (v.y < 0)
return;
Debug.Log(“AA”+ grid1.transform.localPosition);
int idx=(int)((1-v.y) * 12);
Debug.Log(“idx” + idx);
ScrollRect sr = grid1.transform.parent.parent.GetComponent();
grid1.transform.localPosition=new Vector3(grid1.transform.localPosition.x,
idx*20, grid1.transform.localPosition.z);
grid1.transform.GetChild(idx).GetComponentInChildren().color=Color.white;
if(idx>0)
{
grid1.transform.GetChild(idx-1).GetComponentInChildren().color = Color.gray;
}
if (idx < 11)
{
grid1.transform.GetChild(idx + 1).GetComponentInChildren().color = Color.gray;
}
}
