veasing

This is a pure V module that provides easing function calculations.

Install

Install using vpkg

  1. vpkg get veasing

Install using vpm

  1. v install jamestomasino.veasing

Install using git

  1. cd path/to/your/project
  2. git clone https://github.com/jamestomasino/veasing

Install using git submodule

  1. cd path/to/your/project
  2. git submodule add https://github.com/jamestomasino/veasing veasing && git submodule update --init --recursive

Importing the module

For vpkg or git installation

  1. import veasing

For vpm installation

  1. import jamestomasino.veasing as veasing

Usage

Use the animate function to apply an easing function over a range of numbers

  1. fn main () {
  2.   println(veasing.animate(veasing.bounce_ease_out, 0, 100, 100))
  3.   //      easing function ^
  4.   //                                  lower bounds ^
  5.   //                                     upper bounds ^
  6.   //               number of frames/length of return array ^
  7. }
