我设置了一个包含两个网格(立方体)的画布渲染器。我需要做的是catch the click event on each cube
调用它的便捷方法。
到目前为止,我可以捕获所有渲染器上的单击事件,这意味着当我单击cube1和cube2时,单击属于相同的“因为它绑定到renderer
:)
我的问题是,如何绑定每个立方体上的点击事件?
我的相关代码如下:
//dom
var containerPopUp=document.getElementById('popup');
//renderer
var rendererPopUp = new THREE.CanvasRenderer();
rendererPopUp.setSize(420,200);
containerPopUp.appendChild(rendererPopUp.domElement);
//Scene
var scenePopUp = new THREE.Scene();
//Camera
var cameraPopUp = new THREE.PerspectiveCamera(50,60/60,1,1000);
cameraPopUp.position.z = 220;
cameraPopUp.position.y = 20;
//
scenePopUp.add(cameraPopUp);
//Add texture for the cube
//Use image as texture
var img2D = new THREE.MeshBasicMaterial({ //CHANGED to MeshBasicMaterial
map:THREE.ImageUtils.loadTexture('img/2d.png')
});
img2D.map.needsUpdate = true; //ADDED
//Add Cube
var cubeFor2D = new THREE.Mesh(new THREE.CubeGeometry(40,80,40),img2D);
cubeFor2D.position.x =- 60;
cubeFor2D.position.y = 20;
scenePopUp.add(cubeFor2D);
//
var img3D = new THREE.MeshBasicMaterial({ //CHANGED to MeshBasicMaterial
map:THREE.ImageUtils.loadTexture('img/3d.png')
});
img3D.map.needsUpdate = true;
var cubeFor3D = new THREE.Mesh(new THREE.CubeGeometry(40,80,40),img3D);
cubeFor3D.position.x = 60;
cubeFor3D.position.y=20;
scenePopUp.add(cubeFor3D);
//
rendererPopUp.render(scenePopUp,cameraPopUp);
//
animate();
rendererPopUp.domElement.addEventListener('click',testCall,false);//Here the click event is bound on the whole renderer, means what ever object in the renderer is clicked, the testCall method is called.
如您所见,cubeFor2D和cubeFor3D包含在渲染器中。我需要在每个网格上绑定单击事件。我尝试过这个threex.domevent.js
:
var meshes = {};
meshes['mesh1'] = cubeFor2D;
meshes['mesh1'].on('mouseover', function(event){
//response to click...
console.log('you have clicked on cube 2D');
});
但它不起作用,在控制台中,我收到此错误:
TypeError: meshes.mesh1.on is not a function
当然,我包含了API源代码文件:
<script src="threex.domevent.js"></script>
