hi everyone,

iàm trying to undestand how to make my lerp start faster like an impulse, the slow it overtime, iàm using this now

```
float t = currentLerpTime / lerpTime;
t = Mathf.Sin(t * Mathf.PI * 0.5f);
```

but doesnàt work as expected… what i missing?

thank’s you in advance

This is a sinusoidal easing timing, but there are some other useful easing math. Try these:

```
//Sinusoidal (same as yours)
t = Mathf.Sin(t * Mathf.PI / 2f);
//Quadratic
t = t * (2 - t);
//Cubic
t = t * t * t + 1;
//Exponential
t = t == 1f ? 1f : 1f - Mathf.Pow(2f, -10f * t);
//Circular
t = Mathf.Sqrt(1f - (--t * t));
```

If these one not working, you make a mistake elsewhere.

You may want to use an AnimationCurve.

```
[SerializeField] AnimationCurve timeWarpCurve;
float t = timeWarpCurve.Evaluate(Time.time);
t = Mathf.Sin(t * Mathf.PI * 0.5f);
```
