vue3中如何使用live2D
概述
本文将介绍如何在vue3
项目中使用Live2D。
Live2D 介绍
Live2D 是什么
Live2D 是一种用于将二维图像转化为可动画三维模型的技术,主要应用于游戏、虚拟角色和互动应用中。它允许开发者通过对静态图像进行分层和建模,使角色在不同角度下能够进行流畅的动作和表情变化。
Live2D 主要特点
- 动态表现:Live2D 可以让角色在不改变原始图像的情况下,实现多种动作和表情,例如眨眼、微笑、转头等。
- 用户交互:它可以与用户的输入进行互动,比如鼠标移动或触摸屏幕时,角色会作出相应的反馈。
- 应用广泛:被广泛应用于手机游戏、动画、虚拟直播、社交软件等领域。
- 易于使用:通过 Live2D 提供的工具(如 Live2D Cubism),艺术家可以方便地创建和编辑模型,无需深入的编程知识。
Live2D 效果
vue3 中使用 Live2D
如果前端项目是用vite
搭建,则需要在index.html
中引入live2d.min.js
库,因为在 vue 组件中引入会报错。
封装 Live 组件
template
template
部分如下:
<template> <div :class="{ 'vue-live2d': true, 'vue-live2d-on-left': true, // 'vue-live2d-on-right': direction === 'right', }" :style="{ width: `300px`, height: `300px`, position: 'absolute', left: '10px', bottom: '20px', }" @mouseover="openLive2dTool" @mouseout="closeLive2dTool" > <div v-show="true" v-html="data.tipText" :class="{ 'vue-live2d-tip': true, 'vue-live2d-tip-on-top': true, // 'vue-live2d-tip-on-bottom': tipPosition === 'bottom', }" ></div> <canvas :id="customId" v-show="mainShow" :class="{ 'vue-live2d-main': true, 'vue-live2d-main-on-left': true, // 'vue-live2d-main-on-right': direction === 'right', }" width="300" height="300" > </canvas> <div v-show="toolShow" class="vue-live2d-tool"> <span v-for="(tool, index) in tools" :key="index" :class="tool.className" v-html="tool.svg" @click="tool.click" /> </div> <div v-show="toggleShow" @click="openLive2dMain" :class="{ 'vue-live2d-toggle': true, 'vue-live2d-toggle-on-left': true, // 'vue-live2d-toggle-on-right': direction === 'right', }" > <span>Kanban girl</span> </div> </div> </template>
template
部分主要是定义 UI 部分,以及绑定界面点击和hove
的事件,Live2d
的模型是在 canvas 中绘制的。
核心逻辑
核心逻辑主要就是加载Live2D
的模型以及定义事件,其实现如下:
<script setup> import { onMounted, nextTick, ref, computed } from "vue"; import tips from "./options/tips"; // const model = ["Potion-Maker/Pio", "school-2017-costume-yellow"]; const model = ["ShizukuTalk/shizuku-48", "default"]; const apiPath = "https://evgo2017.com/api/live2d-static-api/indexes"; let [modelPath, modelTexturesId] = model; const customId = "vue-live2d-main"; let messageTimer = null; const data = ref({ containerDisplay: { tip: false, main: true, tool: false, toggle: false, }, tipText: "vue-live2d Kanban girl", modelTexturesId: modelTexturesId, }); const changeLive2dSize = () => { document.querySelector( `#${customId}` ).outerHTML = `<canvas id=${customId} width="300" height="300" class="vue-live2d-main"></canvas>`; loadModel(); }; const loadModel = () => { window.loadlive2d( customId, `${apiPath}/${modelPath}/${data.value.modelTexturesId}.json` ); console.log( `Live2D 模型 ${modelPath},服装 ${data.value.modelTexturesId} 加载完成` ); }; const loadRandModel = () => { http({ url: `${apiPath}/models.json`, success: (data) => { const models = data.filter(({ modelPath: i }) => i !== modelPath); const { modelPath: j, modelIntroduce } = models[Math.floor(Math.random() * models.length)]; modelPath = j; showMessage(`${modelIntroduce}`, 4000); loadRandTextures(true); }, }); }; const loadRandTextures = (isAfterRandModel = false) => { http({ url: `${apiPath}/${modelPath}/textures.json`, success: (resp) => { const modelTexturesIds = resp.filter( (modelTexturesId) => modelTexturesId !== data.value.modelTexturesId ); data.value.modelTexturesId = modelTexturesIds[Math.floor(Math.random() * modelTexturesIds.length)]; loadModel(); if (!isAfterRandModel) { showMessage("我的新衣服好看嘛?", 4000); } }, }); }; const showMessage = (msg = "", timeout = 6000) => { if (messageTimer) { clearTimeout(messageTimer); messageTimer = null; } else { data.value.containerDisplay.tip = true; } data.value.tipText = msg; messageTimer = setTimeout(() => { data.value.containerDisplay.tip = false; messageTimer = null; }, timeout); }; const takePhoto = () => { showMessage("照好了嘛,留个纪念吖~"); window.Live2D.captureName = "photo.png"; window.Live2D.captureFrame = true; }; const showHitokoto = () => { http({ url: "https://v1.hitokoto.cn", success: ({ hitokoto, id, creator, from }) => { showMessage( `${hitokoto} <br> - by <a href="https://hitokoto.cn?id=${id}" rel="external nofollow" >${creator}</a> from 《${from} 》` ); }, }); }; const closeLive2dMain = () => { data.value.containerDisplay.main = false; }; const openLive2dMain = () => { data.value.containerDisplay.main = true; }; const closeLive2dTool = () => { data.value.containerDisplay.tool = false; }; const openLive2dTool = () => { data.value.containerDisplay.tool = true; }; const loadEvent = () => { for (const event in tips) { for (const { selector, texts } of tips[event]) { const dom = selector === "document" ? document : document.querySelector(selector); if (dom == null) { continue; } dom.addEventListener(event, () => { const msg = texts[Math.floor(Math.random() * texts.length)]; showMessage(msg, 2000); }); } } }; const http = ({ url, success }) => { const xhr = new XMLHttpRequest(); xhr.onreadystatechange = function () { if (xhr.readyState === 4) { if (xhr.status >= 200 || xhr.status < 300 || xhr.status === 304) { success && xhr.response && success(JSON.parse(xhr.response)); } else { console.error(xhr); } } }; xhr.open("GET", url); xhr.send(null); }; nextTick(() => { loadEvent(); }); onMounted(() => { loadModel(); }); defineProps({ tips: { default: () => tips, type: Object, }, width: { default: 0, type: Number, }, height: { default: 0, type: Number, }, size: { default: 255, type: Number, }, }); const tipShow = computed(() => { return mainShow && data.value.containerDisplay.tip; }); const mainShow = computed(() => { return data.value.containerDisplay.main; }); const toolShow = computed(() => { return mainShow && data.value.containerDisplay.tool; }); const toggleShow = computed(() => { return !mainShow; }); const tools = ref([ { className: "custom-fa-comment", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M256 32C114.6 32 0 125.1 0 240c0 49.6 21.4 95 57 130.7C44.5 421.1 2.7 466 2.2 466.5c-2.2 2.3-2.8 5.7-1.5 8.7S4.8 480 8 480c66.3 0 116-31.8 140.6-51.4 32.7 12.3 69 19.4 107.4 19.4 141.4 0 256-93.1 256-208S397.4 32 256 32z"/></svg>', click: showHitokoto, }, { className: "custom-fa-user-circle", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 496 512" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M248 8C111 8 0 119 0 256s111 248 248 248 248-111 248-248S385 8 248 8zm0 96c48.6 0 88 39.4 88 88s-39.4 88-88 88-88-39.4-88-88 39.4-88 88-88zm0 344c-58.7 0-111.3-26.6-146.5-68.2 18.8-35.4 55.6-59.8 98.5-59.8 2.4 0 4.8.4 7.1 1.1 13 4.2 26.6 6.9 40.9 6.9 14.3 0 28-2.7 40.9-6.9 2.3-.7 4.7-1.1 7.1-1.1 42.9 0 79.7 24.4 98.5 59.8C359.3 421.4 306.7 448 248 448z"/></svg>', click: loadRandModel, }, { className: "custom-fa-street-view", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M367.9 329.76c-4.62 5.3-9.78 10.1-15.9 13.65v22.94c66.52 9.34 112 28.05 112 49.65 0 30.93-93.12 56-208 56S48 446.93 48 416c0-21.6 45.48-40.3 112-49.65v-22.94c-6.12-3.55-11.28-8.35-15.9-13.65C58.87 345.34 0 378.05 0 416c0 53.02 114.62 96 256 96s256-42.98 256-96c0-37.95-58.87-70.66-144.1-86.24zM256 128c35.35 0 64-28.65 64-64S291.35 0 256 0s-64 28.65-64 64 28.65 64 64 64zm-64 192v96c0 17.67 14.33 32 32 32h64c17.67 0 32-14.33 32-32v-96c17.67 0 32-14.33 32-32v-96c0-26.51-21.49-48-48-48h-11.8c-11.07 5.03-23.26 8-36.2 8s-25.13-2.97-36.2-8H208c-26.51 0-48 21.49-48 48v96c0 17.67 14.33 32 32 32z"/></svg>', click: loadRandTextures, }, { className: "custom-fa-camera-retro", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M48 32C21.5 32 0 53.5 0 80v352c0 26.5 21.5 48 48 48h416c26.5 0 48-21.5 48-48V80c0-26.5-21.5-48-48-48H48zm0 32h106c3.3 0 6 2.7 6 6v20c0 3.3-2.7 6-6 6H38c-3.3 0-6-2.7-6-6V80c0-8.8 7.2-16 16-16zm426 96H38c-3.3 0-6-2.7-6-6v-36c0-3.3 2.7-6 6-6h138l30.2-45.3c1.1-1.7 3-2.7 5-2.7H464c8.8 0 16 7.2 16 16v74c0 3.3-2.7 6-6 6zM256 424c-66.2 0-120-53.8-120-120s53.8-120 120-120 120 53.8 120 120-53.8 120-120 120zm0-208c-48.5 0-88 39.5-88 88s39.5 88 88 88 88-39.5 88-88-39.5-88-88-88zm-48 104c-8.8 0-16-7.2-16-16 0-35.3 28.7-64 64-64 8.8 0 16 7.2 16 16s-7.2 16-16 16c-17.6 0-32 14.4-32 32 0 8.8-7.2 16-16 16z"/></svg>', click: takePhoto, }, { className: "custom-fa-info-circle", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M256 8C119.043 8 8 119.083 8 256c0 136.997 111.043 248 248 248s248-111.003 248-248C504 119.083 392.957 8 256 8zm0 110c23.196 0 42 18.804 42 42s-18.804 42-42 42-42-18.804-42-42 18.804-42 42-42zm56 254c0 6.627-5.373 12-12 12h-88c-6.627 0-12-5.373-12-12v-24c0-6.627 5.373-12 12-12h12v-64h-12c-6.627 0-12-5.373-12-12v-24c0-6.627 5.373-12 12-12h64c6.627 0 12 5.373 12 12v100h12c6.627 0 12 5.373 12 12v24z"/></svg>', click: () => {}, }, { className: "custom-fa-times", svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="-40 -40 432 592" fill="currentColor" height="20px" width="20px"><!-- Font Awesome Free 5.15.4 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License) --><path d="M242.72 256l100.07-100.07c12.28-12.28 12.28-32.19 0-44.48l-22.24-22.24c-12.28-12.28-32.19-12.28-44.48 0L176 189.28 75.93 89.21c-12.28-12.28-32.19-12.28-44.48 0L9.21 111.45c-12.28 12.28-12.28 32.19 0 44.48L109.28 256 9.21 356.07c-12.28 12.28-12.28 32.19 0 44.48l22.24 22.24c12.28 12.28 32.2 12.28 44.48 0L176 322.72l100.07 100.07c12.28 12.28 32.2 12.28 44.48 0l22.24-22.24c12.28-12.28 12.28-32.19 0-44.48L242.72 256z"/></svg>', click: closeLive2dMain, }, ]);
