Akilar 「Loading Animation」

https://akilar.top/posts/3d221bf2/

安知鱼 「Heo同款loading动画」

https://anzhiy.cn/posts/52d8.html

本文适用于Butterfly-v4.5及以上，v4.5以下请移步至Akilar大佬的文章

此修改涉及大量主题源码文件

步骤

  1. 修改[Blogroot]\themes\butterfly\layout\includes\loading\index.pug，很明显，这段代码的目的是判断选择的加载动画。读者可以根据代码结构自行改写移除不需要的内容。

      default
        include ./fullpage-loading.pug
else i f theme.preloader.source === 2
  include ./pace.pug
else
    case theme.preloader.load_style    
      when 'gear'
        include ./load_style/gear.pug
        include ./pace.pug

        include ./pace.pug
      default
        include ./fullpage-loading.pug
        include ./pace.pug

尝试解释代码。看到[Blogroot]\_config.butterfly.yml中：

# Loading Animation (加載動畫)
preloader:
  enable: true
  # source
  # 1. fullpage-loading
  # 2. pace (progress bar)
  source: 3
  # pace theme (see https://codebyzach.github.io/pace/)
  pace_css_url: 
  load_color: '#37474f'

if theme.preloader.source就是判断source，如果source: 1则只加载pace，如果source: 2则只加载全屏动画，如果source: x//x为除1, 2之外的数字则都加载。

  1. 新建动画结构模板存放的文件夹，如无特别提示，所有动画模板均存放在[Blogroot]\themes\butterfly\layout\includes\loading\load_style\目录下。

由于作者懒惰，配置文件直接用了[Blogroot]\themes\butterfly\layout\includes\loading\fullpage-loading.pug，强迫症的可以搬到[Blogroot]\themes\butterfly\layout\includes\loading\load_style\下，记得更改[Blogroot]\themes\butterfly\layout\includes\loading\index.pug中的路径。

新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\gear.pug，这是旋转齿轮加载动画。

# Loading Animation (加載動畫)
preloader:
  enable: true
  # source
  # 1. fullpage-loading
  # 2. pace (progress bar)
  source: 3
  # pace theme (see https://codebyzach.github.io/pace/)
  pace_css_url:
-  load_color: '#37474f'
+  load_color: '#000000' # '#37474f'
+  load_style: wizard # default|gear|ironheart|scarecrow|triangles|wizard
  1. 加入pace样式当然 也可以不加样式当然 也可以自己写样式新建[Blogroot]/source/css/progress_bar.css。
