text control

private float timenum=60;
void Update()
    {
    
    
       timenum -= Time.deltaTime;
        if(timenum<=0)
        {
    
    
           timenum = 0;
            return;
        }
        //timeText上的文本显示为timenum的大小，并且以整数形式显示
        timeText.text = timenum.ToString("0");
    }

illustrate

1. Time.deltaTime incremental time, you can refer to the following blog to understand
   the understanding of incremental time
2. timeText.text = timenum.ToString("0"); "0" means in integer form, "0.0" means a decimal form
