基于three.js的事件插件
安装:
npm install object3d-events --save
引入:
import Event from 'object3d-events'
使用:
//初始化事件对象,参数(element事件元素,scene场景实例, camera 摄像机实例, isRayAll是否检测所有 默认true)
const objEvent = new Event(element, scene, camera, isRayAll);
const mesh = new THREE.Mesh(
new THREE.BoxGeometry( 10, 10, 10 ),
new THREE.MeshBasicMaterial({ color: 0xff0000 })
)
//点击事件
mesh.on('click', obj => {
obj.material.color.set( 0x00ffff );
})
//双击事件
mesh.on('dblclick', obj => {
obj.material.color.set( 0x00ffff );
})
//鼠标按下事件
mesh.on('mousedown', obj => {
obj.material.color.set( 0x00ffff );
})
//鼠标松开事件
mesh.on('mouseup', obj => {
obj.material.color.set( 0x00ffff );
})
//鼠标hover事件
mesh.on('hover', obj => {
obj.material.color.set( 0x00ffff );
}, obj => {
obj.material.color.set( 0xff0000 );
})
//移除点击事件
mesh.off('click');
//移除所有事件
mesh.offAll();
//事件元素大小变化,需要重置事件对象:
element.oresize = () => {
objEvent.resize();
}
