const addTextF = (srcText, sizef, heightn, num,objMain) => { const loader = new FontLoader(manager); loader.load('./mapData/FZXiYuan-M01S_Regular.json', (font) => { let geometryText = [] let mesh = { obj: [], gropzhou:[] } const color = 0xffffff; const matLite = new THREE.MeshStandardMaterial({ color: color, emissive: color, emissiveIntensity: 15, transparent: true, opacity: 1, side: THREE.DoubleSide }); geometryText[num] = new TextGeometry(srcText, { font: font, size: sizef, height: heightn, curveSegments: 12, bevelEnabled: false, bevelThickness: 10, bevelSize: 16, bevelOffset: 0, bevelSegments: 5 }); mesh.obj[num] = new THREE.Mesh(geometryText[num], matLite) mesh.obj[num].name = '分支文字' mesh.obj[num].material.name = '分支文字材质' const box = new THREE.BoxHelper(mesh.obj[num], 0xffff00); let TextLength = (box.geometry.attributes.position.array[9] - box.geometry.attributes.position.array[6]) / 2//通过边界框计算出了生成数据长度 mesh.obj[num].position.x -= TextLength mesh.obj[num].position.z=0.4 mesh.obj[num].rotation.x=-90/180 *Math.PI mesh.gropzhou[num]=new THREE.Group() const formatter = new Intl.NumberFormat('en-US'); mesh.gropzhou[num].name='文字轴心'+formatter.format(num); mesh.gropzhou[num].add( mesh.obj[num]) objMain.add( mesh.gropzhou[num] ) } ) }如何把mesh.obj[num]作为返回值返回

可以通过一个简单的函数返回 `mesh.obj[num]`。修改代码如下：

const addTextF = (srcText, sizef, heightn, num,objMain) => { 
  const loader = new FontLoader(manager); 
  loader.load('./mapData/FZXiYuan-M01S_Regular.json', (font) => { 
    let geometryText = [] 
    let mesh = { obj: [], gropzhou:[] } 
    const color = 0xffffff; 
    const matLite = new THREE.MeshStandardMaterial({ 
      color: color, 
      emissive: color, 
      emissiveIntensity: 15, 
      transparent: true, 
      opacity: 1, 
      side: THREE.DoubleSide 
    }); 
    geometryText[num] = new TextGeometry(srcText, { 
      font: font, 
      size: sizef, 
      height: heightn, 
      curveSegments: 12, 
      bevelEnabled: false, 
      bevelThickness: 10, 
      bevelSize: 16, 
      bevelOffset: 0, 
      bevelSegments: 5 
    }); 
    mesh.obj[num] = new THREE.Mesh(geometryText[num], matLite) 
    mesh.obj[num].name = '分支文字' 
    mesh.obj[num].material.name = '分支文字材质' 
    const box = new THREE.BoxHelper(mesh.obj[num], 0xffff00); 
    let TextLength = (box.geometry.attributes.position.array[9] - box.geometry.attributes.position.array[6]) / 2//通过边界框计算出了生成数据长度 
    mesh.obj[num].position.x -= TextLength 
    mesh.obj[num].position.z=0.4 
    mesh.obj[num].rotation.x=-90/180 *Math.PI 
    mesh.gropzhou[num]=new THREE.Group() 
    const formatter = new Intl.NumberFormat('en-US'); 
    mesh.gropzhou[num].name='文字轴心'+formatter.format(num); 
    mesh.gropzhou[num].add(mesh.obj[num]) 
    objMain.add(mesh.gropzhou[num]) 
  }) 
  return mesh.obj[num];
}

这样调用该函数时，就可以得到 `mesh.obj[num]`。
