光滑潮湿或吐温算法 [英] Smooth damp or tween algorithm

问题描述

我想知道的算法平滑潮湿或有人叫它，补间。我想它在Lua preferably但任何帮助。

I would like to know an algorithm for smooth damp or as some people call it, tween. I would like it in Lua preferably but anything will help.

我已经试过看统一的教程，但没有一个算法不能转移code来代替顺利潮湿的功能。

I have tried watching unity tutorials but can't transfer the code without a algorithm to substitute for the smooth damp function.

推荐答案

如果我理解正确的问题，你正在寻找一个宽松的功能。有一个Lua库，它提供了一套在GitHub上缓和功能： https://github.com/EmmanuelOga/easing

If I understand the question correctly, you're looking for an easing function. There is a Lua library that provides a set of easing functions on GitHub: https://github.com/EmmanuelOga/easing

一个例子是：

local function inOutQuad(t, b, c, d)
  t = t / d * 2
  if t < 1 then
    return c / 2 * pow(t, 2) + b
  else
    return -c / 2 * ((t - 1) * (t - 3) - 1) + b
  end
end

其中t =时间，B =开始值，C =价值变动，以及d =持续的时间。

Where t = time, b = begin value, c = change in value, and d = duration.

在这些缓和功能的更多信息，请直接从罗伯特·彭纳在这里（这是上述功能源自）的 http://www.robertpenner.com/easing/
