使用Swift在SceneKit中以编程方式更改3D TextNode的文本

let text = SCNText(string: "Hello World", extrusionDepth: 1.0)

let textNode = SCNNode(geometry: text)

textNode.position = SCNVector3(x: 0, y: 0, z: -10)
textNode.scale = SCNVector3(x: 0.1, y: 0.1, z: 0.1)

scene.rootNode.addChildNode(textNode)

textNode.geometry?.string = "New Text"

import SceneKit

let scene = SCNScene()
let text = SCNText(string: "Hello World", extrusionDepth: 1.0)
let textNode = SCNNode(geometry: text)
textNode.position = SCNVector3(x: 0, y: 0, z: -10)
textNode.scale = SCNVector3(x: 0.1, y: 0.1, z: 0.1)
scene.rootNode.addChildNode(textNode)

// 更改文本节点的文本内容
textNode.geometry?.string = "New Text"
