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.positionconst 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 + 0.02textMesh.position.z = pos.z + 0.18textMesh.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 = falselet 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.$state.p1Deck.forEach((v: any, i: any) => {let obj = CARD_DICT.find((b: any) => b.card_id === v.card_id)if (obj) {let card = new Card(obj)let mesh = card.init()mesh.position.set(0, 0.005 * i, 0)mesh.rotateX(180 * (Math.PI / 180)) // 弧度mesh.name = v.namemesh.userData._ATK = mesh.userData.ATK // _ATK用于实时计算当前攻击力deckGroup.add( mesh );}})let position = new THREE.Vector3(0, 0.005 * commonStore.$state.p1Deck.length, 0)renderDeckText(deckGroup, `${commonStore.$state.p1Deck.length}`, commonStore.$state._font, position)}

页面效果如下：
