Question about bot chatting

Hey KWo! :clap::clap:
It's been a long time since I came here.

I have a question on how your bots detect keywords in their chats. I am referring to the source code. Also, can you tell me how you detect which player said what.

can you give me the c++ code for this or tell me how to do this?

Thanks

Re: Question about bot chatting

The podbot mm sources are here.

In the file bot_client.cpp there is a function BotClient_CS_SayText. It intercepts who (ucEntIndex) and what (pBot->SaytextBuffer.szSayText) is saying and puts it to the buffer, then answer with some delay (pBot->SaytextBuffer.fTimeNextChat) after recognizing the keywords in the function BotCheckKeywords in the file bot_chat.cpp. In that file there is a function called BotPrepareChatMessage, which You should take a look at, too. In the BotCreate function in the file bot.cpp there are also such line:

Code:

   // Assign how talkative this Bot will be

   pBot->SaytextBuffer.fChatDelay = RANDOM_FLOAT (4.0, 10.0);

   pBot->SaytextBuffer.cChatProbability = RANDOM_LONG (40, 100); // KWo - 31.03.2006

The first parameter says how often the bot will be talk (how many seconds between 2 chats from the same bot), the second one is also checking the probability the bot wants to talk after that delay. I hope You have got the full answer.

Re: Question about bot chatting

what is the void *p? I see that ucEntIndex = *(unsigned char *) p;

I don't understand what you did very well.

Can you explain it to me in C++ how it intercepts who is talking and what he is saying? do you need to hook saymsg or textmsg? What is the hlsdk thing for intercepting chat messages?

It's a pointer to the data without any fixed format (can be int, can be float, can be char, can be whatever - depanding on the assignement).

It wasn't me - it was Count Floyd in 99% of code... Then take a C++ book and learn it. I'm not going to be Your teacher... I just don't have time for that.

Text/say message? Find in engine.cpp the call for BotClient_CS_SayText - then You will see what kind of message it is...

BTW - why exactly do You need to know that bot chating function? Is there something You want to fix (not working correctly)? Or You are trying to make Your own bot?
