Prerequisites

The following prerequisites are required in order for you to create your first bot by following this tutorial.

Real World

• This tutorial assumes that you were able to successfully build libsecondlife! If you have not compiled libsl, please follow the instructions on the Getting Started wikipage.

• Also, if you have no experience with the C# (c-sharp) programming language, I highly recommend that you stop now and please follow the list of links to csharp tutorials located here.

• A libsl bot that is able to login successfully. If you don't know how to create a libsl bot, please go to the "How to create a basic libSL bot" wikipage

The Code

Note: We are assuming that our main "SecondLife" variable is named "client." If you have a different name for this variable, please substitute the name accordingly

 
client.Self.OnChat += new AgentManager.ChatCallback(Self_OnChat); 
//run the above bit of code when you want to start processing all chat
//make sure you have already defined "Self_OnChat" though!
 
static void Self_OnChat(string message, ChatAudibleLevel audible, ChatType type,  ChatSourceType sourceType, string fromName, LLUUID id, LLUUID ownerid, LLVector3 position)
{
      //process chat here, see explanation of parameters below
}
 

Parameters for Self_OnChat:

• message (string) What was said
• audible (not used)
• type (ChatType) How it was said (see this page on monodoc for the list of ChatTypes)
• sourceType (ChatSourceType) What kind of thing said it (System, Object, or Avatar)
• fromName (string) Whats the name of the person/object that said it
• id (LLUUID) Whats the key of the person/object that said it
• ownerid (LLUUID) If it was an object, who owns it?
• position (LLVector3) Where is the person/object that said it

Notes

• ChatType.Normal = Saying (20m range).. Do NOT use ChatType.Say, it is an obsolete version and will likely be removed in the near future.
• Try to check to see if the chattype is not "StartTyping" or "StoppTyping" before you process the text.. otherwise you get blank messages
