[Telebot区块链游戏机器人]
❤博主广交技术好友，喜欢文章的可以关注一下❤
1.编写目的
本文章为记录自己开发基于区块链和Telebot实现的[石头、剪刀、布]游戏的过程,加深自己对区块链知识的理解和使用,加深对TeleBot依赖库的使用,同时希望可以帮助到有想实现相关功能的朋友.
2.实现功能
2.1 Wallet功能
用户可以通过/create命令命令创建游戏wallet,同时可以输入地址或扫码向该wallet发送一定数量的游戏代币,使用/wallet命令可以显示当前游戏wallet内的剩余代币数量。
2.2 游戏功能
用户可以将bot机器人添加到公开群组,同时在群组内发送/game命令创建具有奖励随机结果的游戏,使用不同的人向群组内回复该游戏/pk进行对战,获取对战结果并向游戏wallet发送设定的奖励游戏代币,用户可以使用/del删除当前已创建游戏。
2.3 提出功能
用户可以通过/bind命令绑定外部wallet并进行代币提出.
2.4 辅助功能
用户可以输入/rules查看游戏规则,输入/help命令查看机器人命令及解释。
3.功能实现详解
3.1 wallet功能
用户通过/create命令命令创建游戏wallet可以参考我的博客生成solana公私钥,/wallet显示wallet信息是通过solana.py根据保存的用户公钥查询.
def getBalance(publicKey:str): solana_client = Client(rpc_url) #公钥转换 pubkey=Pubkey.from_string(publicKey) tokenPublicKey=Pubkey.from_string(BOGGY_TOKEN_MINT) #获取SOL余额 sol_balance = solana_client.get_balance(pubkey) #获取SPL代币余额 token_account=solana_client.get_token_accounts_by_owner_json_parsed(pubkey,TokenAccountOpts(mint=tokenPublicKey)) if noTokenAccount(token_account): #不存在代币账户时,则余额为0 token_balance=0.0 else: token_account_json=token_account.value[0].account.to_json() token_balance=json.loads(token_account_json)['data']['parsed']['info']['tokenAmount']['uiAmount'] sol_balance=(sol_balance.value/10**9) return sol_balance,token_balance同时为方便用户使用,这边会将用户公钥通过qrcode库转换为二维码供用户扫码,主要代码为:
import qrcode from io import BytesIO from PIL import Image import qrcode.main def generate_qr(data): # 生成普通二维码 qr = qrcode.main.QRCode( version=1, box_size=10, border=4, ) qr.add_data(data) qr.make(fit=True) qr_img = qr.make_image(fill_color="black", back_color="white") # 将二维码图片保存到 BytesIO 对象中 img_io = BytesIO() qr_img.save(img_io, format='PNG') img_io.seek(0) return img_io 实现效果:
3.2 游戏功能
游戏功能的设计思路是当用户在群组内输入/game时,根据(群组id+用户id+消息id)生成唯一的游戏id并通过json文件存储创建者生成的随机值信息.存储信息如下:
{ "create_user_id": 5385955983, "create_username": "GameOfBoggy", "create_select": 0, "pk_user_id": 2038830708, "pk_username": "USERT1223", "pk_select": 1, "pk_select_hex": "4b32e3c83744655cd4ab5cc991a342c99f52c73fa83f2393a995d53baf7aeb42", "amount": 20, "winner": "USERT1223", "create_select_hex": "bd55d5aa6e461c63c811ff78bb00753c517eba47f086e563783a5e023ff342af", "timestamp": 1721092512.869742, "create_drand_hex": "e3b4d8b6af061ddc40449d87c57c06d93de8fa73dff0055a07cc8dadb047dd1e", "pk_drand_hex": "808391bb3761db7f5be8ba296e143154f043ecced8e7a693698c8490300fe34f" }这里的是使用本地secrets库和调用远程的drand随机数链生成两个hash值(create_drand_hex和create_select_hex为创建者游戏结果计算hash,pk_select_hex和pk_drand_hex为pk者游戏结果计算hash,这些结果面会保存到链上以保证游戏结果公平性和随机性.),这两个hash值转换为整数相加并对3取余获得随机结果,以保证游戏的随机性和不可预测性:
调用远程drand API:
def get_drand_randomness(): # Drand API endpoint url = "https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971/public/latest" # Send request to Drand response = requests.get(url) if response.status_code == 200: # Parse the JSON response data = response.json() randomness = data['randomness'] return randomness else: return secrets.token_hex()计算游戏随机结果:
def get_random_hex_int(): select_hex=secrets.token_hex() drand_hex=get_drand_randomness() hex_int = int(select_hex, 16) drand_int = int(drand_hex,16) select=(drand_int+hex_int)%3 return select,select_hex,drand_hex为保证游戏的美观性,这边使用图片+文字方式让机器人回复用户随机结果:
def random_game(bot,message,type,create_username): select,select_hex,drand_hex = get_random_hex_int() imgPath="./img/{}.png".format(img[select]) msgText="<b>[{}] You random [{}]! @{}</b>".format(type,img[select],create_username) send_message=bot.send_photo(message.chat.id, open(imgPath, 'rb'), caption=msgText,parse_mode='HTML') return select,send_message,select_hex,drand_hex 游戏奖励发放给获胜者为代币转移操作,实现代码如下(这里的draw_data即为计算出结果的hash值,将其备注添加链上):
#向绑定账户发送代币 def drawTokenAccount(sender_public_key:str,privateKey:str,draw_public_key:str,tokenAmount,draw_data): solana_client = Client(rpc_url) #发送者 sender_pubkey = Pubkey.from_string(sender_public_key) #接收者 draw_pubkey = Pubkey.from_string(draw_public_key) #Token代币地址 token_mint_address = Pubkey.from_string(BOGGY_TOKEN_MINT) #发送者keypair sender_keypair=Keypair.from_base58_string(privateKey) try: #spl_client客户端 source_token_account=get_associated_token_address(sender_pubkey,token_mint_address) dest_token_account=get_associated_token_address(draw_pubkey,token_mint_address) #交易 transfer_instruction = transfer_checked( TransferCheckedParams( program_id=TOKEN_PROGRAM_ID, source=source_token_account, mint=token_mint_address, dest=dest_token_account, owner=sender_pubkey, amount=int(float(tokenAmount) * 1000000000), decimals=9, ) ) memo_instruction=create_memo(MemoParams( program_id=MEMO_PROGRAM_ID, signer=sender_pubkey, message=draw_data.encode('utf-8') )) # #获取最新的区块hash recent_blockhash_resp = solana_client.get_latest_blockhash() recent_blockhash=recent_blockhash_resp.value.blockhash # # 创建交易并添加转账指令 transaction = Transaction() transaction.add(set_compute_unit_limit(200000)) transaction.add(set_compute_unit_price(7500)) transaction.add(transfer_instruction) transaction.add(memo_instruction) #设置最新区块hash transaction.recent_blockhash=recent_blockhash #设置手续费支付地址为发送者 transaction.fee_payer=sender_pubkey #签名 transaction.sign(sender_keypair) #发送交易 response = solana_client.send_raw_transaction(transaction.serialize()) #打印交易 return response.value except Exception as e: print(f"Exception occurred: {str(e)}") return "error"实现效果:
/game 20 即创建了一个奖励为20代币的游戏,这里随机的是[剪刀]
/pk pk者出了[布],所以创建者获得了奖励.
我们可以点击按钮在链上查看奖励内容.
可以看到这里包含了一个转移代币操作,是从pk者转移到创建者中的,同时包含了生成随机结果的hash值以保证游戏的公开和公平性。
3.3 提出功能
用户输入/bind 绑定自己的链上地址后,提出功能即为代币转移操作,主要实现代码如下,这边直接根据用户的ID查到用户的创建的游戏wallet公钥私钥并进行转移:
def drawTokenFromUserId(send_user_id,draw_user_id,gameId,draw_data): publicKey,privateKey=get_account(send_user_id) drawPublicKey=getPublicKey(draw_user_id) amount=get_game_amount(gameId) tx=drawTokenAccount(publicKey,privateKey,drawPublicKey,amount,draw_data) return amount,tx3.4 辅助功能
辅助功能即为telebot消息的回复,实现代码如下:
/rules:
from telebot import types def handle_rules(bot, message): # 处理 /start 命令 markup = types.InlineKeyboardMarkup() item1 = types.InlineKeyboardButton("BOGGY GROUP",url="https://t.me/BoggyCoin") markup.add(item1) welcome_message=( "<b>" "1.Before starting the game, you need to create(/create) a game wallet and transfer a small amount of sol and BOGGY tokens inward\n\n" "2.You can send '/game [amount]' create a game(default amount:500),and the Pker reply /pk with [GAME](need enough sol and BOGGY)\n\n" "3.Waiting for the results, the winner will receive the bonus set by the game creator\n\n" "4.The [Scissors] will win [Paper],[Parer] will win [Rock],[Rock] will win [Scissors]\n\n" "5.You Can at /wallet,draw you all token in you bind wallet,you can send '/bind [address]' bind you wallet\n\n" "[Create With #BOGGY]" "</b>" ) bot.send_photo(message.chat.id,open("./img/rules.jpeg","rb"),welcome_message,parse_mode='HTML',reply_markup=markup) def register_handlers(bot): bot.message_handler(commands=['rules'])(lambda message: handle_rules(bot, message)) /help:
from telebot import types def handle_help(bot, message): markup = types.InlineKeyboardMarkup() item1 = types.InlineKeyboardButton("BOGGY GROUP",url="https://t.me/BoggyCoin") markup.add(item1) help_text = ( "<b>Welcome!</b>\n" "<b>Here are the available commands:</b>\n" "<b>[/create] Create you game wallet [DM*]</b>\n" "<b>[/bind] Bind you draw wallet [DM*]</b> \n" "<b>[/wallet] Show you wallet Info and Draw [DM*]</b>\n\n" "<b>[/game] Create Game with amount</b>\n" "<b>[/pk] Reply the Game Message and Pk it</b>\n" "<b>[/rules] View more detailed game rules</b>\n\n" "<b>The [DM*] need DM Bot</b>" ) bot.send_photo(message.chat.id,open("./img/help.jpeg","rb"),help_text, parse_mode='HTML',reply_markup=markup) def register_handlers(bot): bot.message_handler(commands=['help'])(lambda message: handle_help(bot, message)) 4.测试视频
