Lerp is slightly jittery

Code (CSharp):

1. public class TestingLerp : MonoBehaviour
2. {
3.     public Transform pos1;
4.     public Transform pos2;
5.     public float seconds;
6.     float time;
7.  
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         time = Time.time;
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.         time +=Time.deltaTime;
18.         transform.position = Vector3.Lerp(pos1.position, pos2.position, time/ seconds);
19.     }
20. }
21.  

Doing some Lerp testing. With seconds = 10f; and running 70FPS, I can still visually see that the LERP jitters a bit. How come? This code should be fine as long for the first 10 seconds?

 

Try to use

Time.smoothDeltaTime

Why are you setting your timer to Time.time instead of 0 on Start?

 

Yeah it doesn't make sense here.
