我們透過連接生成式AI的API，再規定提示詞以及走法規則，理論上就可以實現與AI的對弈，接下來的幾天，我們就來探討及實作如何利用AI來達成人機對弈的效果，並做出一些總結
首先需要到chat-gpt的官方網站申請API Token，從入口網站登入帳號，點擊右上角的創建新密鑰，輸入密鑰名稱後，直接創建
創建完成後，請妥善保存密鑰，這個視窗只會出現一次，關掉就無法再查看了
再來就是要創建該密鑰的付款資訊，前往付款頁面，選信用卡或其他方式付款，填入相關資訊
選擇需要的額度後，就可以用該密鑰送出請求了
我們回到CreateJoinRoom，新增一個入口，並帶gamemode值"ai"到下個頁面
btn_ai.setOnClickListener(v -> {
random_room_number = random.nextInt(10000);
gameMode="ai";
CreateRoom();
});
接下來，我們在Player1ChessGame中的getSuccess新增判斷是否為ai對奕的情況
if(gameMode.equals("ai") && moveState.equals("black") && getCount==1){
gptMove.setRoomKey(roomKey);
gptMove.setTurn(String.valueOf(turn));
gptMove.setCastling(castling);
gptMove.setChessmanMoveData(chessmanMoveData);
gptMove.setChessboardData(chessboardData);
gptMove.setGPT();
}
接著實作GPTMove

可以發現其實與先前的實作相差無幾，差別在於說沒有實作吃過路兵，因為本範例會先以簡單能達成的目標測試gpt的程度
