Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

使用

import { VirtualControlEditor, type ButtonInfo } from 'virtual-control-editor'

// 最基本使用,聚焦编辑器后,点击键盘按键即可在鼠标位置出现按键
const editor = new VirtualControlEditor(container, editorRatio, false)
  • hostElement <HTMLElement> 宿主元素
  • containerRatio <number> 编辑器宽高比,会根据宿主元素的宽进行计算
  • showGuideLine <boolean> 是否展示网格辅助线,默认为 true
  • keyboardButtonShape <string> 按键默认形状,值为 ellipserect,默认为 ellipse
  • bgRatio <number> 背景图(流)像素比,默认与 containerRatio 一致
  • combineCount <number> 支持组合键的数量,默认为 2

事件订阅

editor.events.on('focus', ({ ids, type, content, code }) => {
  // 聚焦按键
})
editor.events.on('blur', () => {
  // 失焦
})
editor.events.on('add', (id, type) => {
  // 新增按钮
})
editor.events.on('remove', (id, type) => {
  // 移除按钮
})

新增鼠标按钮

// 鼠标左键
editor.assistant.appendMouseLeftButton(offsetX, offsetY, width, height, opacity, imageSrc)
// 鼠标右键
editor.assistant.appendMouseRightButton(offsetX, offsetY, width, height, opacity, imageSrc)
// 鼠标中键
editor.assistant.appendMouseScrollWheelButton(offsetX, offsetY, width, height, opacity, imageSrc)
// 摇杆,最后一个参数是摇杆的样式图片以及遥感底部的样式图片
editor?.assistant.appendJoystick(JoystickType, offsetX, offsetY, width, height, opacity, [
  string,
  string,
])

初始化数据

const data = [
  {
    xPercent: 0.23625,
    yPercent: 0.150093808630394,
    widthPercent: 0.125,
    heightPercent: 0.18761726078799248,
    codes: null,
    showName: '',
    schemeKeys: 'scroll-wheel',
    aspectRatio: 1,
    srcList: [],
    type: 30,
    opacity: 0.8,
    anchor: 'screen',
    shape: 'ellipse',
  },
] as ButtonInfo[]

editor.assistant.initData(data)

更改键盘按键形状

editor.changeShpae(shape, ids)

获取最终数据

editor.snapshot(): ButtonInfo[]

移动按钮位置,相对于整个容器的坐标

editor.moveTo(id, x, y)

覆盖原始按钮样式

  • srcList 是一组 base64数组
  • Joystick 支持两张,第一张是底盘图片,第二张是摇杆图片
  • 其余按钮只按照第一张去绘制
editor.drawImageToButton(id, ...srcList)

键盘按钮添加描述

editor.editContent(id, content)

更改按钮透明度

  • rate 透明度范围 0 - 1
editor.updateOpacity(id, rate)

更改按钮大小

  • rate 大小为 0 - 1,相对于宽度的比例
editor.updateSize(id, rate)

更改形状

  • 形状为:rectellipse,ids非必传,默认全部
editor.changeShape(shape, ids)

移除按钮

editor.removeButton(id)

移除所有按钮

editor.removeAll()

展示或隐藏辅助线

editor.showOrHideGuideLine(showOrHide)

更改canvas容器大小比例

editor.updateRatio(ratio, width?: number)

销毁

editor.destroy()

结果类型 ButtonInfo

interface ButtonInfo {
  xPercent: number // 相对于流播放可视区域的 x 轴的百分比
  yPercent: number // 相对于流播放可视区域的 y 轴的百分比
  widthPercent: number // 相对于流可视区域宽度的百分比
  heightPercent: number // 相对于流可视区域高度的百分比
  codes: number | null // 键盘 keyCode
  combination: number[] // 组合键,是键盘 keyCode 的集合
  showName: string | null
  schemeKeys: string | null
  aspectRatio: number
  type: KeyboardKeyType
  opacity: number
  srcList: string[]
  anchor: 'screen' | 'graphics'
  shape: KeyboardButtonShape
}
