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 🙏

zjj-virtual-arcade-controller

v0.1.1

Published

A Vue 3 and Three.js virtual arcade controller component library.

Readme

ZJJ Virtual Arcade Controller

基于 Vue 3 + Three.js 的虚拟街机控制器组件库。

zjj-virtual-arcade-controller 提供三层组件:

  • VirtualArcadeController:开箱即用的组合控制器,包含 1 个摇杆、方向箭头、动作按钮、按钮标签和布局。
  • ThreeJoystick:独立 3D 摇杆组件。
  • VirtualActionButton:独立 3D 动作按钮组件。

适用于网页游戏、触屏控制面板、键盘映射调试、街机风格交互原型等场景。

功能特性

  • 拟真的 Three.js 摇杆和动作按钮。
  • 支持鼠标、触摸和键盘输入。
  • 支持平面俯视和 2.5D 玩家视角。
  • 支持配置按钮布局、颜色、尺寸、标签和上排按钮缩进。
  • 支持配置摇杆方向键映射。
  • 提供 Vue 3 组件类型、props 类型和事件载荷类型。
  • 样式通过 zjj-virtual-arcade-controller/style.css 导出。

安装

npm install zjj-virtual-arcade-controller

Peer dependencies:

npm install vue three

快速开始

<script setup lang="ts">
import { ref } from 'vue'
import {
  VirtualArcadeController,
  type ArcadeAxisPayload,
  type ArcadeButtonConfig,
  type ArcadeButtonPayload,
  type JoystickKeyboardMapping,
} from 'zjj-virtual-arcade-controller'
import 'zjj-virtual-arcade-controller/style.css'

const axis = ref<ArcadeAxisPayload>({ x: 0, y: 0 })
const pressed = ref<Record<string, boolean>>({})

const joystickKeyboardMapping: JoystickKeyboardMapping = {
  up: ['KeyT'],
  down: ['KeyG'],
  left: ['KeyF'],
  right: ['KeyH'],
}

const buttons: ArcadeButtonConfig[] = [
  { id: 'dash', label: 'X', keyBinding: 'KeyU', row: 'top' },
  { id: 'skill', label: 'Y', keyBinding: 'KeyI', row: 'top' },
  { id: 'guard', label: 'RB', keyBinding: 'KeyE', row: 'top' },
  { id: 'menu', label: 'LB', keyBinding: 'KeyQ', row: 'top' },
  { id: 'jump', label: 'A', keyBinding: ['KeyJ', 'Space'], row: 'bottom' },
  { id: 'attack', label: 'B', keyBinding: 'KeyK', row: 'bottom' },
  { id: 'trigger', label: 'RT', keyBinding: 'KeyZ', row: 'bottom' },
  { id: 'special', label: 'LT', keyBinding: 'KeyC', row: 'bottom' },
]

function onAxisChange(payload: ArcadeAxisPayload) {
  axis.value = payload
}

function onAxisEnd() {
  axis.value = { x: 0, y: 0 }
}

function onButtonChange(payload: ArcadeButtonPayload) {
  pressed.value[payload.id] = payload.pressed
}
</script>

<template>
  <VirtualArcadeController
    :buttons="buttons"
    color="#eb1f2f"
    arrow-color="#eb1f2f"
    view-mode="angled"
    :joystick-keyboard-mapping="joystickKeyboardMapping"
    :joystick-size="182"
    :button-size="82"
    :top-offset="14"
    @axis-change="onAxisChange"
    @axis-end="onAxisEnd"
    @button-change="onButtonChange"
  />
</template>

组件层级

| 组件 | 适用场景 | | --- | --- | | VirtualArcadeController | 需要完整控制器内核时使用:摇杆、方向箭头、按钮、标签和布局。 | | ThreeJoystick | 只需要独立摇杆,并希望自己设计布局时使用。 | | VirtualActionButton | 只需要单个 3D 按钮,或希望自己组合多个按钮时使用。 |

本地 demo 里的白色底盘、螺丝、街机外壳、SELECT / START / COIN 和状态卡片不属于当前 npm 包 API。

独立摇杆

<script setup lang="ts">
import { ref } from 'vue'
import { ThreeJoystick } from 'zjj-virtual-arcade-controller'
import 'zjj-virtual-arcade-controller/style.css'

const axis = ref({ x: 0, y: 0 })

function onMove(x: number, y: number) {
  axis.value = { x, y }
}
</script>

<template>
  <ThreeJoystick
    color="#eb1f2f"
    arrow-color="#eb1f2f"
    view-mode="angled"
    :size="182"
    @move="onMove"
    @end="axis = { x: 0, y: 0 }"
  />
</template>

独立按钮

<script setup lang="ts">
import { ref } from 'vue'
import { VirtualActionButton } from 'zjj-virtual-arcade-controller'
import 'zjj-virtual-arcade-controller/style.css'

const pressed = ref(false)
</script>

<template>
  <div>
    <VirtualActionButton
      color="#eb1f2f"
      view-mode="angled"
      :size="82"
      key-binding="KeyJ"
      @press="pressed = true"
      @release="pressed = false"
    />
    <span>A {{ pressed ? 'Pressed' : 'Idle' }}</span>
  </div>
</template>

VirtualArcadeController API

Props

| Prop | 类型 | 默认值 | 说明 | | --- | --- | --- | --- | | buttons | ArcadeButtonConfig[] | 8 个默认动作按钮 | 动作按钮配置。 | | color | string | #eb1f2f | 摇杆头和按钮颜色。 | | arrowColor | string | 跟随 color | 方向箭头颜色。 | | joystickKeyboardMapping | JoystickKeyboardMapping | 方向键 + WASD | 摇杆方向键映射。 | | viewMode | 'flat' \| 'angled' | flat | 渲染视角。 | | joystickSize | number | 182 | 摇杆 canvas 尺寸,单位 px。 | | buttonSize | number | 82 | 单个按钮 canvas 尺寸,单位 px。 | | topOffset | number | 14 | 上排按钮的水平缩进。 | | showLabels | boolean | true | 是否渲染按钮标签。 |

事件

| 事件 | 载荷 | 说明 | | --- | --- | --- | | axis-change | { x: number; y: number } | 摇杆移动时触发。 | | axis-end | 无 | 摇杆回中时触发。 | | button-change | { id: string; label: string; pressed: boolean } | 任意动作按钮按下或释放时触发。 |

插槽

| 插槽 | 说明 | | --- | --- | | joystick | 渲染在摇杆区域周围,可用于放玩家编号、装饰或提示。 |

键盘映射

joystickKeyboardMapping 使用 KeyboardEvent.code

默认映射:

const joystickKeyboardMapping: JoystickKeyboardMapping = {
  up: ['ArrowUp', 'KeyW'],
  down: ['ArrowDown', 'KeyS'],
  left: ['ArrowLeft', 'KeyA'],
  right: ['ArrowRight', 'KeyD'],
}

自定义示例:

<VirtualArcadeController
  :joystick-keyboard-mapping="{
    up: ['KeyT'],
    down: ['KeyG'],
    left: ['KeyF'],
    right: ['KeyH'],
  }"
/>

建议不要让摇杆方向键和动作按钮的 keyBinding 重叠;如果重叠,同一个键盘输入会同时触发摇杆和按钮事件。

类型

export type ButtonRow = 'top' | 'bottom'
export type ArcadeViewMode = 'flat' | 'angled'
export type JoystickDirection = 'up' | 'down' | 'left' | 'right'
export type JoystickKeyboardMapping = Partial<Record<JoystickDirection, string[]>>

export type ArcadeButtonConfig = {
  id: string
  label: string
  keyBinding?: string | string[]
  row?: ButtonRow
}

export type ArcadeAxisPayload = {
  x: number
  y: number
}

export type ArcadeButtonPayload = {
  id: string
  label: string
  pressed: boolean
}

导出

export { default as VirtualArcadeController } from './VirtualArcadeController.vue'
export { default as ThreeJoystick } from '../components/ThreeJoystick.vue'
export { default as VirtualActionButton } from '../components/VirtualActionButton.vue'
export type {
  ArcadeAxisPayload,
  ArcadeButtonConfig,
  ArcadeButtonPayload,
  ArcadeViewMode,
  ButtonRow,
  JoystickDirection,
  JoystickKeyboardMapping,
} from './types'

注意事项

  • 使用任意组件时,都需要引入 zjj-virtual-arcade-controller/style.css
  • vuethree 是 peer dependencies,需要由宿主项目安装。
  • VirtualActionButton 只渲染 3D 按钮本体。按钮文字建议由业务侧自己排版,或直接使用 VirtualArcadeController
  • 当前包输出 Vue 3 组件和 ESM 产物。

本地开发

npm install
npm run dev
npm run build

本项目使用 Vite 8,需要 Node 20.19+22.12+
