Description

The following snippet provides short functions for floating point numbers. See the usage section for individualized information.

Usage

• Hermite - This function will interpolate while easing in and out at the edges.
• Lerp - This function stands for Linearly Interpolate and is a work around for a bad Mathf.Lerp function as of 1.2b2.

C# - Mathfx.cs

<csharp>using UnityEngine; using System;

public class Mathfx {

   public float Hermite(float edge0, float edge1, float t)
   {
       float tt = Mathf.Min(Mathf.Max((t - edge0) /(edge1 - edge0), 0.0f), 1.0f);
       return tt * tt * (3F - 2F * tt);
   }
   
   public float Lerp(float start, float end, float value)
   {
       return ((1.0f - value) * start) + (value * end);
   }

} </csharp>
