I recently crafted a JavaScript script to accomplish a specific task, and overall it was working smoothly. However, as I attempted to simplify the code for a demonstration here on this platform, I encountered two issues. Unfortunately, during this 'reduction' process, a third error emerged, causing the entire script to cease functioning properly. Below is the JavaScript snippet in question:
var container, stats;
var camera, scene, renderer;
var group1, group2;
var mouseX = 0, mouseY = 0;
var map_width = 512;
var map_height = 512;
var windowHalfX = window.innerWidth / 2;
var windowHalfY = window.innerHeight / 2;
init();
animate();
function createMesh(filename) {
var geometry = new THREE.SphereGeometry( 70, 40, 40 );
var texture = new THREE.TextureLoader(filename);
texture.needsUpdate = true;
var material = new THREE.MeshBasicMaterial( { map: texture, overdraw: 0.5 } );
var mesh = new THREE.Mesh( geometry, material );
return mesh;
}
function init() {
container = document.getElementById( 'container' );
camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 1, 2000 );
camera.position.z = 500;
scene = new THREE.Scene();
group1 = new THREE.Group();
var mesh = createMesh("textures/tree1.jpg");
group1.add( mesh );
group1.position.x = 00;
scene.add( group1 );
group2 = new THREE.Group();
var mesh = createMesh("textures/tree2.jpg");
group2.add( mesh );
group2.position.x = 250;
scene.add( group2 );
renderer = new THREE.WebGLRenderer({ alpha: true });
renderer.setClearColor( 0xffffff, 0 );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
container.appendChild( renderer.domElement );
}
function animate() {
requestAnimationFrame( animate );
render();
}
function render() {
camera.position.x += ( mouseX - camera.position.x ) * 0.05;
camera.position.y += ( - mouseY - camera.position.y ) * 0.05;
camera.lookAt( scene.position );
group1.rotation.y -= 0.005;
group2.rotation.y -= 0.015;
renderer.render( scene, camera );
}
The intention behind this script is to display multiple spheres with diverse textures applied to them. However, upon embedding this code into an HTML document, I encountered the following error:
TypeError: n is undefined
This error is consistently appearing and seems to be originating from within the THREE.js library. I am seeking guidance on resolving this issue so that I can successfully display two spheres adorned with a 'tree' texture...?
Below is the body of the HTML code:
<body>
<div id="container"></div>
<script src="js/build/three.min.js"></script>
<script>
>> the above code snippet <<
</script>
</body>
