moving enemy randomly with smoothing

Code (CSharp):

1.  void Alternate()
2.     {
3.      
4.        
5.            
6.             if (t > duration)
7.             {
8.                 Change();
9.             }
10.             else
11.             {
12.                 t += Time.deltaTime;
13.                 amount = Mathf.SmoothStep(cp.Angle, destination, Mathf.Abs(duration));
14.             }
15.        
16.     }
17.  
18.     void Change()
19.     {
20.         t = 0;
21.         duration = Random.Range(0.5f, 3f);
22.         random = Random.Range(0, 2) * 2 - 1;
23.         duration *= random;
24.         destination = ((Time.deltaTime * duration) * rotateSpeed) + cp.Angle;
25.         print("NEW");
26.     }

the code above is my attempt so far (Change() gets called in start and Alternate() gets called in update) what i want to do is rotate my enemy around a cylinder randomly, with smoothing applied. but instead it just moves it increasingly fast in only one direction. How should i go about solving this?

 

Hi,

Put in some Debug.Logs to see what is happening. To see if for example the duration value, and destination are what you expect them to be. Perhaps the Change() method is never called?
