vue3+threejs新手从零开发卡牌游戏（二十四）：添加p2战斗逻辑

用代码模拟p2战斗逻辑，按流程进行步骤拆分：

1.p2抽卡

2.p2召唤怪兽上场

3.p2战斗

其中战斗部分分为几种情况：

情况一：p2场上卡牌由大到小进行排序，按序轮询可以攻击的卡牌，然后攻击p1场上卡牌由大到小攻击力最高的同时攻击力不超过当前p2卡牌的那个，如果p2场上最大的攻击力不能突破p1场上卡牌，那就不攻击并将该卡牌攻击次数置为0，进行下一个循环，当p2场上所以卡牌攻击次数均为0时，认为战斗阶段结束，可以进行下一个回合。

情况二：p1场上卡牌已经全部被破坏，而此时p2场上还有卡牌未行动，那么此时卡牌可以直接攻击p1玩家。

情况三：p2战斗阶段时，p1场上怪兽区没有卡牌时，全员即可轮询直接攻击p1玩家。

修改utils/common.ts：


// 卡牌攻击特效
const cardAttack = (card1: any, card2: any, callback: any) => {
  console.log("cardAttack", card1, card2)
  let isP1 = card1.userData.areaType.indexOf("己方") > -1
  // 获取card1世界坐标
  let pos1 = new THREE.Vector3(0, 0, 0)
  card1.getWorldPosition(pos1)
  // 获取card2世界坐标
  let pos2 = new THREE.Vector3(0, 0, 0)
  card2.getWorldPosition(pos2)

  // 动画1：移动到对方卡面前
  const twA = new TWEEN.Tween({
    x: pos1.x,
    y: pos1.y,
    z: pos1.z,
    card1,
  })
  twA.to({
    x: pos2.x,
    y: pos2.y + 0.1,
    z: isP1 ? pos2.z + 1.4 * 0.8 : pos2.z - 0.7 * 0.8,
  }, 300)
  twA.easing(TWEEN.Easing.Quadratic.Out)
  twA.onUpdate((obj: any) => {
    obj.card1.position.set(obj.x, obj.y, obj.z)
  })
  twA.onComplete(function() {
    //动画结束：关闭允许透明，恢复到模型原来状态
    TWEEN.remove(twA)
    callback && callback()
  })
  // 动画2：退回到原位置
  const twB = new TWEEN.Tween({
    x: pos2.x,
    y: pos2.y + 0.1,
    z: isP1 ? pos2.z + 1.4 * 0.8 : pos2.z - 0.7 * 0.8,
    card1,
  })
  twB.to({
    x: pos1.x,
    y: pos1.y,
    z: pos1.z,
  }, 400)
  twB.easing(TWEEN.Easing.Quadratic.In)
  twB.onUpdate((obj: any) => {
    obj.card1.position.set(obj.x, obj.y, obj.z)
  })
  twB.onComplete(function() {
    //动画结束：关闭允许透明，恢复到模型原来状态
    // TWEEN.remove(twA)
    // callback && callback()
  })
  twA.chain(twB)
  twA.start();
}
export { cardAttack }


// p2玩家手牌召唤上场逻辑
const p2FindHandToSiteCard = (cards: any, mana: any) => {
  let newCards = cards.filter((v: any) => v.userData.Mana <= mana)
  console.log("p2玩家手牌召唤上场逻辑", cards, newCards)
  if (newCards.length > 0) {
    newCards.sort((a: any, b: any) => {
      return a.Mana - b.Mana
    })
    return newCards[0]
  }
  return null
}
export { p2FindHandToSiteCard }
