Adding selected character/ .gltf model in a-frame

587 Views Asked by Abhishek Kumar At 16 April 2025 at 04:04

I'm stuck on one problem.

There are three items I've built into the options. So, I want to click on any one of the buttons to change the avatar as per the click. If anyone selected a male avatar so it should be reflected in others also. For example if there are 4 users. And from that 3 are male and 1 is female and the female selected a female avatar. So, she can able to see others as a male avatar and others can see her as a female avatar(.gltf model).

Is there any way to dynamically add the .gltf model in a-frame and also update it for others?

<body>
<!-- ============================ Start Model Selection ==========================  -->
<div class="container" style="z-index: 1; position: fixed">
  <div class="content_container content_container-1">
    <div class="svg">
      <img
        src="https://s2.svgbox.net/illlustrations.svg?ic=selfie-boy"
        alt="Boy"
      />
    </div>
    <div class="content content-1">Boy</div>
  </div>

  <div class="content_container content_container-1">
    <div class="svg">
      <img
        src="https://s2.svgbox.net/illlustrations.svg?ic=selfie-girl"
        alt="Girl"
      />
    </div>
    <div class="content content-2">Girl</div>
  </div>

  <div class="content_container content_container-1">
    <div class="svg">
      <img
        src="https://s2.svgbox.net/illlustrations.svg?ic=my-robot"
        alt="Robot"
      />
    </div>
    <div class="content content-3">Robot</div>
  </div>
</div>

<!-- ============================ End Model Selection ==========================  -->

<a-scene background="color: #FAFAFA">
  <a-entity environment="preset: forest;  grid: cross"></a-entity>
</a-scene>

This is the code I've written for this.

The docs mention syncing custom components (and gltf-model is a component), and it's quite simple. Lets say we want a model with the standard heads:

Add the entity with the gltf-component to the networked template:

<template id="avatar-template">
  <a-entity class="avatar">
    <a-entity class="model" gltf-model></a-entity>
    <a-sphere class="head">
    <!-- The rest of the template definition -->

Add it to the NAF.schemas:

NAF.schemas.add({
     template: '#avatar-template',
     components: [
       // the default position, rotation, color
       {
         // the model entity has a .model class
         selector: '.model',
         // we want the gltf-model component to sync between clients
         component: 'gltf-model'
       },

Add the model to your local client:

<a-entity id="player" camera
         networked="template:#avatar-template;attachTemplateToLocal:false;"
         position="0 1.6 0" wasd-controls look-controls>
  <a-entity class="model" gltf-model="#fox" model-changer></a-entity>
</a-entity>

Create the model-changer component which changes the model when the images are clicked:

AFRAME.registerComponent("model-changer", {
  init: function() {
    // nothing special here - change the models when the images are clicked
    const btn1= document.getElementById("btn1")
    const btn2= document.getElementById("btn2")

    // for whatever reason i need to update the model with the actual source, not just the id
    function getAssetSrc(id) {
      return document.getElementById(id).getAttribute("src")
    }
    btn1.addEventListener("click", e => {
      this.el.setAttribute("gltf-model", getAssetSrc(model1))
    })
    btn2.addEventListener("click", e => {
      this.el.setAttribute("gltf-model", getAssetSrc(model2))
    })
  }
})

Check it out in this glitch - the images should change the models:
