I know there is a plugin which comes with MUSH which ables people to use the chat system easier, but how would one go about adding your hit points to when ever you chat?

I'm just learning to script using lua, so I don't even know where to start, any help would be appreciated.

*/*hp */*m */*mv *br

That's my prompt

I also am having trouble being able to send things into chat on triggers, for example

<triggers>
<trigger
enabled="y"
match="* has been blinded."
send_to="12"
sequence="100"
>
<send>ChatEverybody "(%1)is blind", 1</send>
</trigger>
</triggers>

doesn't work I get

Compile error
World: Untitled world
Immediate execution
[string "Trigger: "]:1: unexpected symbol near '<'

No clue what that means.

First, paste the trigger in like this:

http://mushclient.com/pasting

The < and > symbols are part of the XML way that triggers are displayed. Don't type them into the trigger itself.

Second, the examples in the chat write-up are for VBscript. Lua needs brackets around function arguments, a minor change. So, change:


ChatEverybody "(%1)is blind", 1

to:


ChatEverybody ("%1 is blind", 1)

As for adding the HP to every message, I'll look into that now ...

This plugin shows how you can add your HP to every outgoing message.

It detects outgoing chat messages, and uses your most recent prompt (if any) to amend the message by putting your HP after the quote that is normally in the message.

In other words, it changes:


Nick chats to everybody, 'hi there everyone'

to:

Nick chats to everybody, '[20] hi there everyone'

... assuming your HP are 20.

To use this, copy between the lines, paste into a text document (eg. MUSHclient's notepad) and save to disk as Add_HP_to_chat_messages.xml.

Then use File menu -> Plugins to install as a plugin.

If anyone else wants to use it, you would need to change the trigger "match" line to match your prompt.
