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,

},
});
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(() => {
