Class: NodeOperator ​

节点操作接口

Details

主要用来设置节点的显示，隐藏，颜色；获取包围盒，坐标值。

Examples

js
let sceManager =await cloud.getSceneManager();
let operator =  await sceManager.getNodeOperator();
var node = sceManager.getRootNode3D()
await operator.showOutLine(node!,true)
let sceManager =await cloud.getSceneManager();
let operator =  await sceManager.getNodeOperator();
var node = sceManager.getRootNode3D()
await operator.showOutLine(node!,true)

Methods ​

setState ​

▸ setState(nodes, state): Promise<boolean>

设置节点状态

Examples

js
const sceManager = await cloud.getSceneManager()
const ope = await sceManager.getNodeOperator()
const node = await sceManager.getRootNode3D()
const state: NodeState = {
  color: 'rgb(122,111,452)',
  opacity: 100,
  show: false,
}
await ope.setState([node!], state)
const sceManager = await cloud.getSceneManager()
const ope = await sceManager.getNodeOperator()
const node = await sceManager.getRootNode3D()

  show: false,
}
await ope.setState([node!], state)

Parameters ​

NameTypeDescription
nodesNode[]节点数组
stateNodeState节点的一些状态，目前包括节点的颜色（color）、透明度（opacity）、是否展示（show）。

Returns ​

Promise<boolean>

设置节点状态，支持先设置状态再加载数据，(只追加数据),自身覆盖了setState相关功能

}
await ope.setIdsState(["7256854545455485455"], state)
const sceManager = await cloud.getSceneManager()
const ope = await sceManager.getNodeOperator()
const state: NodeState = {
  color: 'rgb(122,111,452)',
