tween hardstep function in csharp

To tween a hardstep function in C#, you can use Unity's built-in Mathf class along with an easing function library such as LeanTween or DOTween.

Here's an example of how to tween a hardstep function using LeanTween:

main.cs
// set up initial values
var startValue = 0f;
var endValue = 10f;
var duration = 1f;
var easeType = LeanTweenType.custom;

// define the hardstep easing function
float Hardstep(float t, float b, float c, float d) {
    return (t < 0.5f) ? b : c;
}

// use LeanTween to tween the value using the hardstep function
LeanTween.value(gameObject, startValue, endValue, duration)
    .setEase(easeType)
    .setEase(Hardstep) // set the custom easing function
    .setOnUpdate((value) => {
        // do something with the value as it changes
    });

In this example, we define the Hardstep function to be used as the easing function for the tween. We then pass this function as a parameter to the setEase method along with the LeanTweenType.custom enum. Finally, we use the setOnUpdate method to update some value as the tween progresses.

You can use a similar approach with other tweening libraries such as DOTween to achieve a hardstep function tween.
