原理

1. 将棋盘中能够胜利的五子连珠方法遍历一个数组;
2. 当AI持棋时,遍历棋盘中所有棋子的空位;
3. 如果用户落子该位置,给用户该位置的五连珠方式进行加分:1连10分,2连20分,3连40分,4连80分;
4. 如果AI落子该位置,给AI该位置的五连珠方式进行加分:1连15分,2连25分,3连45分,4连85分;
5. 最后对该位置的分值进行比较,取最大分值位置的坐标,AI在最大分值位落子。

AI代码

computerAI(){
  var playerScore = [],computerScore = [];
  var max = 0,u = 0, v = 0;
  for (var i = 0; i < this.type; i++){
   playerScore[i] = [];
   computerScore[i] = [];
   for (var j = 0; j < this.type; j++){
    playerScore[i][j] = 0;
    computerScore[i][j] = 0;
   }
  }
  for (var x = 0; x < this.type; x++) {
   for (var y = 0; y < this.type; y++) {
    var po = this.checkPosition(x, y);
    if (po.status == 0){
     for (var k = 0; k < this.count; k++) {
      if (this.WIN_ARRAY[x][y][k]){
       if (this.player[k] == 1){
        playerScore[x][y] += 10;
       } else if (this.player[k] == 2){
        playerScore[x][y] += 20;
       } else if (this.player[k] == 3) {
        playerScore[x][y] += 40;
       } else if (this.player[k] == 4) {
        playerScore[x][y] += 80;
       }
       if (this.computer[k] == 1) {
        computerScore[x][y] += 15;
       } else if (this.player[k] == 2) {
        computerScore[x][y] += 25;
       } else if (this.player[k] == 3) {
        computerScore[x][y] += 45;
       } else if (this.player[k] == 4) {
        computerScore[x][y] += 85;
       }
      }
     }
     if (playerScore[x][y] > max){
      max = playerScore[x][y];
      u = x;
      v = y;
     } else if (playerScore[x][y] == max){
      if (computerScore[x][y] > computerScore[u][v]){
       u = x;
       v = y;
      }
     }
     if (computerScore[x][y] > max) {
      max = computerScore[x][y];
      u = x;
      v = y;
     } else if (computerScore[x][y] == max) {
      if (playerScore[x][y] > playerScore[u][v]) {
       u = x;
       v = y;
      }
     }
    }
   }
  }
  var point = this.checkPosition(u,v);
  if(point.status == 0){
   this.oneStep(point);
   point.status = -1;
   this.COMPUTER_ARRAY.push(point);
   for (var i = 0; i < this.count; i++) {
    if (this.WIN_ARRAY[point.pointX][point.pointY][k]) {
     this.computer[k]++;
     this.player[k] = 100;
    }
   }
   if (point.status == -1 && this.COMPUTER_ARRAY.length >= this.CHESS_LEN && this.checkWin(point, this.COMPUTER_ARRAY)) {
    wx.showToast({ title: '白棋胜利!' });
    this.isStart = false;
   }
   if (this.isStart) {
    this.isWho = !this.isWho;
   }
  }
 }

注意

此种方式实现的算法AI的防守比较重,进攻性不强,有待优化。而且很简单就能给AI设置陷阱而取得胜。
