using UnityEngine.UI;
using UnityEngine.Timeline;

public class TimeLineDemo : MonoBehaviour,ITimeControl
{
public string str = "是否要情话足够动听，才能叫例外";
public Text text;

public void SetTime(double time)
{
if((int)(time*3)<str.Length)
{
text.text = str.Substring(0, (int)(time * 3));
}
else
{
text.text = str;
}
}

public void OnControlTimeStart()
{
print("OnControlTimeStart");
}

public void OnControlTimeStop()
