本文介绍了Three.js：无法在dat.GUI中更改值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个dat.GUI实例。我向该实例添加了 comboBox以选择可能的值。当我运行我的应用程序时，dat.GUI与comboBox一起出现，但是有一个问题：我无法更改其默认值（我的gui被冻结），这是我的代码：
i have an instance of dat.GUI. I added a "comboBox" to that instance to make a selection of possible values. When i run my app, the dat.GUI appears with the comboBox but there is a problem: I cannot change it's default value (my gui is frozen), here is my code:

<head>

<style>
body { margin: 0; }
canvas { width: 100%; height: 100% }
</style>
</head>
<body>
<div id="container"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="js/three.min.js"></script>
<script src="js/optimer_regular.typeface.js"></script>
<script src="js/TrackballControls.js"></script>
<script src="js/stats.min.js"></script>
<script src="js/threex.dynamictexture.js"></script>
<script src="js/dat.gui.min.js"></script>
<script>
//Basic Three components
var scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 0.1, 1000 );
//position camera
camera.position.z = 700;
//Set camera controls
var controls = new THREE.TrackballControls( camera );
controls.rotateSpeed = 1.0;
controls.zoomSpeed = 1.2;
controls.panSpeed = 0.8;
controls.noZoom = false;
controls.noPan = false;
controls.staticMoving = true;
controls.dynamicDampingFactor = 0.3;
controls.keys = [ 65, 83, 68 ];
//Set the renderer
var renderer = new THREE.WebGLRenderer( { antialias: false } );
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
//Set the lights
var light;
scene.add( new THREE.AmbientLight( 0x404040 ) );
light = new THREE.DirectionalLight( 0xffffff );
light.position.set( 0, 1, 1 );
scene.add( light );
//GUI
initGUI();
//Let's add a cube
var geometry = new THREE.BoxGeometry( 50, 50, 50 );
var material = new THREE.MeshBasicMaterial( { color: 0x5484d3 } );
var cube = new THREE.Mesh( geometry, material );
cube.position.set(0,20,50)
scene.add( cube );
function initGUI(){ //HERE IS THE MEAT, I THINK
var LevelView = function() {
this.level = 'Operacion';
// Define render logic ...
};
var gui = new dat.GUI();
var text = new LevelView();
gui.add(text, 'level', [ 'Operacion', 'Procesos', 'Participantes', 'Fuentes de Datos', 'Logica de software', 'Telecomunicaciones', 'Infraestructura'] ).onChange(function(value){
this.level = value;
});
}
function animate() {
requestAnimationFrame( animate );
render();
}
//Render scene
function render() {
controls.update();
renderer.render( scene, camera );
}
animate();
</script>
</body>
</html>
？我在做什么错？我需要能够使用GUI更改值。
¿What i am doing wrong? I need to be able to change values with my GUI.
推荐答案
解决方案：如果将鼠标控制的相机与three.js一起使用，则必须在MouseListener中注释以下行mouseDown操作：
Solution: If you use a mouse-controlled camera with three.js, you have to comment the following line in the MouseListener of the mouseDown action:
event.preventDefault();
