 using UnityEngine.UI;
 
 public class CircleProcess : MonoBehaviour
 {
     private bool IsStart = false;
 
     public Transform process;
     public Transform indicator;
 
     public int targetProcess = 2;
     private float currentAmout = 0;
   
     void Update()
     {
         if (currentAmout < targetProcess)
         {
             if (IsStart)
             {
                 currentAmout += Time.deltaTime;
                 Process();
             }
             else
             {
                 currentAmout -= Time.deltaTime;
                 Process();
             }
         }
         else
         {
             indicator.GetComponent<Text>().text = "激活成功";
         }
     }
     public void Process()
     {
         indicator.GetComponent<Text>().text = ((int)(currentAmout * 50)).ToString() + "%";
         process.GetComponent<Image>().fillAmount = currentAmout / 2.0f;
         if (currentAmout > targetProcess)
             currentAmout = targetProcess;
         if (currentAmout<0)
             currentAmout = 0;
     }
 
     public void Clickprocess(bool bStart)
     {
         IsStart = bStart;
     }
