I am trying to move an object up to a specific spot when I push up, and down to a specific spot when i push down. There’s no magic to it. First, the Slerp function is only called once after the user pressed the mouse button. Lerp works, when I use it, instead of ‘smoothing out’ the object’s position or number, it INSTANTLY jumps from one value to another based on the last digit; time. Lerp(minimum, maximum, t), 0, 0); // . deltaTime * speed); This lerps the target’s current HP fine (lerpTo is the calculated value of HP after the change occured), but I can’t make it take 1 second long; the amount of time it takes the lerp to complete is longer the higher the value is (lerping 100 HP is longer than 1000 HP). InverseLerp(min, max, myValue); var theResult = Mathf. and increase 前言线性插值是一个在游戏中经常使用的数学，但是在Unity社区，经常被错误的使用，并且传播。追溯其渊源，就连官方文档和官方视频也在错误的使用，这令初学者非常的困惑。 首先我们来看一下Lerp函数的三个参数都是 文章浏览阅读7. Leave feedback.
