在utils/common.ts下新建渲染场上手牌文字方法：

// 渲染场上手牌文字
const renderSiteCardText = (mesh: any, font: any) => {
  return new Promise((resolve, reject) => {
    let pos = mesh.position
    const geometry = new TextGeometry( `ATK ${mesh.userData._ATK}`, {
      font,
      size: 0.2,
      height: 0,
      curveSegments: 12,
      bevelEnabled: false,
      bevelThickness: 0,
      bevelSize: 0,
      bevelSegments: 0
    });
    geometry.center()
    const material = new THREE.MeshBasicMaterial({ 
      // color: new THREE.Color("#00a2ff"),
      color: new THREE.Color("white"),
      // alphaHash: true
    })
    const textMesh = new THREE.Mesh( geometry, material ) ;
    textMesh.position.y = pos.y + 0.02
    textMesh.position.z = pos.z + 0.18
    textMesh.rotateX(-90 * (Math.PI / 180)) // 弧度
    textMesh.name = "攻击力"

    mesh.add(textMesh)

    resolve(true)
  })
}
export { renderSiteCardText }

​

然后在game/index.vue中绘制场上卡牌时调用：

// 绘制场上卡牌
const renderSiteCard = async (data: any, mesh: any) => {
  let p1_handGroup = scene.getObjectByName("p1_handGroup")
  let position = new THREE.Vector3(0, 0, 0)
  mesh.getWorldPosition(position)
  mesh.userData.empty = false
  let oldMesh = p1_handGroup.children.find((v: any) => v.name === data.name)
  let newMesh = oldMesh.clone()
  newMesh.userData.areaType = mesh.name // 用来记录卡牌在哪个区域，怪兽区、墓地、手牌、卡组、场地等
  newMesh.scale.set(0.8, 0.8, 0.8)
  handRef.value.removeHandCard(oldMesh)
  scene.add(newMesh)
  newMesh.position.set(position.x, position.y, position.z)
  await renderSiteCardText(newMesh, commonStore.$state._font)

  console.log(123, newMesh)
}

相当于在手牌上场时给当前上场的卡牌添加一个TextGeometry，这里需要注意的是，展示的攻击力不能直接拿userData里的ATK，而要添加一个新的ATK来实时计算攻击力值，所以在game/deck/p1.vue中还需要修改下代码：

const init = () => {
  setDeckPos()
  addDeckWireframe()
  commonStore.$state.p1Deck.forEach((v: any, i: any) => {
    let obj = CARD_DICT.find((b: any) => b.card_id === v.card_id)
    if (obj) {
      let card = new Card(obj)
      let mesh = card.init()
      mesh.position.set(0, 0.005 * i, 0)
      mesh.rotateX(180 * (Math.PI / 180)) // 弧度
      mesh.name = v.name
      mesh.userData._ATK = mesh.userData.ATK // _ATK用于实时计算当前攻击力
      deckGroup.add( mesh );
    }
  })

  let position = new THREE.Vector3(0, 0.005 * commonStore.$state.p1Deck.length, 0)
  renderDeckText(deckGroup, `${commonStore.$state.p1Deck.length}`, commonStore.$state._font, position)

}

页面效果如下：
