So, you need to first understand how the server communicates with the client and vice-versa.
The server can "talk" with the client using client commands:
clientCmdSomeCommandNameHere() (this isn't relative to your question, but good to know).
The client can communicate with the server via server commands:
serverCmdSomeCommandNameHere().
First you will need a /help command which in Torquescript looks like:
function serverCmdHelp(%client)
{
//code..
}To display a chat message, you can use several different commands, here is one:
messageClient(%client,'',"some text here");To get user input when they type in the chat, you will need to understand how Packages (
tutorial) work and package the correct function which you can find by using Trace (
tutorial)
I've given you enough information to get the help command working so that it displays the options. After you get that down, myself or someone else will continue to help you further.
