Hyperlink in OnPluginPacketReceived

Hello.

I play Materia Magica, and I have a plugin that I wrote that shows me room (number and coordinates) information in the compass area. I would like to be able to walk back to a particular room with just the click of the room number, but I don't know how I would do that. I was thinking of using an anchor, but I don't know how that could send information to the client and not the browser. Any thoughts? Is this even possible?

Why are you doing this in OnPluginPacketReceived?

I did a mapper for Materia Magica here:

https://www.gammon.com.au/forum/?id=10667

In the mapper, you just click on a room and it walks you there.

Because that's how I'm getting the room information. I made enough room for room names to not be truncated, so that's why I didn't just use triggers and a GMCP call.

Yeah, I know I can do that, but if the room is not on my mapper because I'm too far away from it or it's in a different area, or if I don't know exactly where that particular room is on my map, then clicking it inline with a hyperlink would be more convenient.

I don't understand what you're trying to say here.

Basically if the room name is a certain length, the game doesn't display it all. I do.

Also, I'm displaying the room information in the first line of 3 in my compass, so that's also why I need to use the callback and not a trigger, because the GMCP doesn't register until the second line.

Yes, but ... how are you going to get to that room if it's in a different area? A fundamental thing to know is the route to the room.

Who would know, then?



Making hyperlinks in OnPluginPacketReceived is not at all supported. You are supposed to use that to detect GMCP stuff, and record it, or maybe to fiddle with packets slightly. Not to inject hyperlinks.

You could conceivably remember the room you are in (presumably that is what you are doing) and use that to calculate a route to the room you want to go to. But not in OnPluginPacketReceived itself.

I don't understand that part.

I don't understand what you are saying. On your compass you have a room (like, adjacent?) and you want to walk to it by a click, is that it?

You'll get better advice if you give a lot more detail about what you want to do. Like, an example. Right now it is coming over as an X-Y Problem.
Areadien USA #8
OK, let me give an illustration then.

Let's say I have a room that looks like this inside an area called Rune Forest:

 A Cliff Edge                                                   12084 [ 700, 680] -      N      -
(-------------------------------------------------------------------------------) - <---(M)---> E
                                                                                  -      -      -


I want to be able to click on the 12084 when I'm in another room and send a speedwalk to room 12084. If I'm in a different area, or if the room is off my mapper when I'm in Rune Forest, then I won't be able to click it inside the mapper.

Does this make sense now?

I'd do this with a trigger, but I wouldn't be able to get the room number until the second line of the compass. That's why I'm using the OnPluginPacketReceived callback to display this information.

What makes you unable to trigger on the first line? I agree with Nick. Something isn't coming through in your explanation. If you can lay out an ordered sequence of discrete message and action events like "The server sends me A, then the server sends me B, then I do C, and the result is that D is displayed at E like this...." it will help.

So it works like this.

The server sends the packet, but I can't read room information with the GMCP plugin until the second line of the compass. I want to put the information on the first line, which is why I'm using the callback.
Areadien USA #11
Hmm, let me think on this because I'm not sure how to explain it better. I think I'll have to look at my code tomorrow to get a better idea.

But basically the plugin I'd have to call doesn't get the information I need until after I want to use it.

Edit: I did not mean to post twice. I thought I had deleted the other comment because it basically just said the same confusing thing I had already said. But trying to delete it doesn't work because I get an error saying I didn't write the post, which I did.

The way you have explained it, the very first line you showed above has the room number on it. So why can't that be a hyperlink that you click on if you want to go to room 12084?

I don't see what GMCP has to do with it. If you need GMCP to arrive on the second line to know what room it is, how come you can show it on the first line?

You have to give us more than that. What does the packet look like?

OK, so this is what the room packet normally looks like:

And this is what the room usually looks like:

(-------------------------------------------------)     - <---(M)---> -

I have edited the room packet directly through OnPluginPacketReceived to be able to show the room info since, like I said,

	res, val = CallPlugin("f67c4339ed0591a5b010d05b", "gmcpval", "room.num") -- calls the MM_GMCP_handler plugin


won't work until the second line of the compass. In fact, I did a trigger to show why, and here's what I got:

 Tellerium Parcel Service                               -      N      -
val = 
(-------------------------------------------------)     - <---(M)---> -
                                                        -      -      -


The trigger was

<triggers>
	<trigger enabled="y" keep_evaluating="y" match="^ Tellerium Parcel Service                               -      N      -$" omit_from_output="n" regexp="y" send_to="12" sequence="100">
		<send>res, val = CallPlugin("f67c4339ed0591a5b010d05b", "gmcpval", "room.num") -- calls the MM_GMCP_handler plugin
ColourNote("red", "black", "val = " .. val)</send>
	</trigger>
</triggers>


So the GMCP value is empty on the first line.

Is it actually the second line of the compass or is it the end of the packet?

It's the second line of the compass that gets the room information. I can demonstrate after I get off work.

But I can see the gmcp message before the first line, so...

Nick, OnPluginTelnetSubnegotiation isn't called until CMUSHclientDoc::DisplayMsg?


In the meantime, Areadien, I bet you could store a variable in OnPluginPacketReceived but then only use the value in a trigger on the first line.

Actually, I got an idea. I can gag the compass, then save the information I need until the third line, and then display the compass there. That way, I can get the room information on the second trigger, and then use the HyperLink. I know you can see it in the room packet itself, but for some reason, the room information isn't sent to triggers until the second line of the compass.

I hope that makes sense. I'm not the best online communicator, as you can probably already tell. Thanks for being patient with me, you two.
