three.js:单击鼠标时停止自动旋转 [英] three.js: stop automatic rotation while mouse is clicked
问题描述
我正在玩three.js.我构建了一个旋转的多维数据集,您也可以在OrbitControls的帮助下旋转它.现在,我的目标是在单击鼠标时停止自动旋转,因此当用户想要自己旋转立方体时,不会分散用户的注意力.所以动画:
I am playing around with three.js. I built a rotating cube, which you also can rotate around with the help of OrbitControls. Now I am aiming to stop the automatic rotation when the mouse is clicked, so the user won't be distracted when he wants to rotate the cube by himself. So the animation:
function animate() {
mesh.rotation.x += .015;
mesh.rotation.y += .015;
mesh.rotation.y += .015;
render();
requestAnimationFrame( animate );
}
应该在鼠标按下时停止并在释放鼠标时继续.如何与OrbitControls结合使用?
should stop, when mouse is down and continue, when mouse is released. How can I achieve it in combination with OrbitControls?

Javascript:
var camera;
var scene;
var renderer;
var mesh;
var geometry;
var material1;
var material2;
var material3;
var material4;
var material5;
var material6;
var materials;
var meshFaceMaterial;
var controls;
init();
animate();
function init() {
camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 1, 1000 );
camera.position.z = 25;
controls = new THREE.OrbitControls( camera );
controls.addEventListener( 'change', render );
scene = new THREE.Scene();
light = new THREE.DirectionalLight( 0xffffff );
light.position.set( 1, 1, 1 );
scene.add( light );
light = new THREE.DirectionalLight( 0xffffff );
light.position.set( -1, -1, -1 );
scene.add( light );
light = new THREE.AmbientLight( 0x222222 );
scene.add( light );
geometry = new THREE.CubeGeometry( 10, 10, 10);
material1 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub1.jpg') } );
material2 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub2.jpg') } );
material3 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub3.jpg') } );
material4 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub4.jpg') } );
material5 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub5.jpg') } );
material6 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub6.jpg') } );
materials = [material1, material3, material5, material6, material4, material2];
meshFaceMaterial = new THREE.MeshFaceMaterial( materials );
mesh = new THREE.Mesh(geometry, meshFaceMaterial );
mesh.position.z = 0;
scene.add( mesh );
renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.getElementById('render').appendChild( renderer.domElement );
window.addEventListener( 'resize', onWindowResize, false );
render();
}
function animate() {
mesh.rotation.x += .015;
mesh.rotation.y += .015;
mesh.rotation.y += .015;
render();
requestAnimationFrame( animate );
}
function render() {
renderer.render( scene, camera );
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
render();
}
推荐答案
您可以使用mousedown
和mouseup
事件侦听器.
You can use the mousedown
and mouseup
event listeners.
类似这样的东西:
var isMouseDown = false;
function init(){
window.addEventListener('mousedown', onMouseDown);
window.addEventListener('mouseup', onMouseUp);
}
function onMouseDown(){
isMouseDown = true;
}
function onMouseUp(){
isMouseDown = false;
}
function animate() {
if(!isMouseDown){
mesh.rotation.x += .015;
mesh.rotation.y += .015;
mesh.rotation.y += .015;
}
render();
requestAnimationFrame( animate );
}
此处是可工作的数字笔.
