Inactive [CHAT] Applet Chat [1.2.5-R4.0]

What is AppletChat?

AppletChat is a plugin that hosts a separate server as a chat server. Users can talk with other people using the chat client, and with players who are on the hosted minecraft server. The client can be embedded into a webpage, and downloaded as a easily executable .jar file. It supports a few emoticons (which work in-game!), can disconnect and reconnect to different servers, and has support for font colours.

This plugin will later be expanded to have a login system for administrators to easily manage their server through a different version of the client, making banning, kicking, a browsing through user information much quicker since it can be done though a graphical environment. An android version of this client may also be possible as well!

If you found this plugin useful, please donate! It will motivate me to work on my plugins.

This plugin is on DevBukkit.

* Fixed my sentence fragments in the post, and reformatted.

If any moderator is reading this submission, can you also take note that the editor is very difficult to use due to a large amount of errors. Every time I edit the post, my line breaks multiply, both in IE and Google Chrome. It doesn't do this in Linux though.

I don't see how this isn't getting accepted. This plugin is unique, and quite advanced.

Plugins dont get accepted so fast... just be patient. I like the idea, good job!

Thanks. I'm going to make a port of the client for the android, hopefully. I've decided to learn the Android API, since I already know Java pretty well.

Sorry, I've been a little out of date with the whole bukkit site setup. I just noticed that bukkit forums and bukkit dev are separate, and that there is a much more convenient section for posting plugins on bukkit dev.

Should I post there as well, remove this post and post there, or just keep this one?

It's a good idea to create a BukkitDev page too, it's good for hosting updates and files you want/need people to download.

This is awesome. Can't wait to try it out.

How does this connect to mc? If I use other plugins for connecting to the chat like through teamspeak or dynmap, does the messages through these show up in the chat?

Yes, you use the client to speak directly to minecraft players and other people using the client. In the minecraft chat, all the players in the server can see the messages from AppletChat clients, and everyone using the client receives all the messages sent from the users in game.

Is there confusion on how this works or something?

I have a video explaining the plugin a little, but I have a slow internet connection and it takes hours to upload, even after it's converted to MP4. Is there something I should add on the post to make the functionality of the plugin clearer, or something else?

I did, after I noticed that the accounts for bukkit dev and the forums are somewhat separate. Sort of confusing from a consumer point of view.

Tell me about it. The devpage is connected to curse which I already have a different account on since the days I played wow. Lovely...

It needs a scroll wheel for the chat, If 100 people are talking and you need to to see what someone said it's gone before you know it. Oh, and maybe a pause and play for incoming chat !

A scroll wheel is a good idea, I may implement that. A pause and play for incoming chat is plain retarded though.

Dude i vouch for you all the way. This thing is amazing. I will use it all the time.
I hope you will continue to work on this as it is really amazing and should be on all servers.
I especially like the fact i dont need to use sql or any other bs like that. It so simple, and i thank you for that.
Keep up the good work!

Thanks! I'm hoping more people will notice the significance of this plugin.

This is very good, VERY GOOD for your first released plugin. I vouch, and this is something I've never seen before. It is sort of like IRC, but not close at all. I look forward to see all the other plugins you make and would like to see your popularity grow. Maybe you can post a video, a tutorial. (Althought there probably isnt much to show.)
This is amazing and look forward to amazing plugins by you.

I would post a video, but I don't like the sound of my own voice. I'l get someone else to blab about the plugin.

I've looked into the protocol that this uses.

Code:

0000000: 0035 0033 0066 006c 0036 0075 0073 0065  .5.3.f.l.6.u.s.e

All characters are 2 bytes long, big endian.
Special characters begin with 0x30. known commands are 0x3000 to send a message and 0x3001 to change username.
At the beginning of the connection, the string 53fl6 is sent, then a change username message.
As long as the server sends something non-zero when the connection is opened, the client display "Connected".
The client sends messages by writing the color first, then the message, then finally 0x3000 to send the print command.
The client changes username by writing the username, then 0x3001 to change the username.
Usernames can contain color.
The colors are the same as the Minecraft ones; i.e, they use a § and then a letter from 1 to f for colors - 1 is blue, f is white; I don't know the others.

The server response to that fragment:

The server responds with one byte, 0x01, to signify that authentication succeeded. As far as I can tell, any non-zero value would work. From then on, the protocol it uses is the same as the client chat protocol - color, >> or player nickname, color, player message. (Your messages are echoed back with >>, other players' messages gets their nickname prepended.)

Also, the chat color is printed in the console.

good, very usefull and easy to setup ! but can you kick spammer ? or add a link with permission and username...

may you add some notifications on login and logout? please
Anyway nice work and very useful when we can't go on the server.

Thank you for your insightful analysis of my protocol. I'm surprised you haven't assumed this is text IO, I used it not for for simplicity for constructing a protocol, but for compatibly with minecraft chat. However, I don't know why the colour code is being printed in your console. It shouldn't.

I will remove the ">> " string before the received messages just for the sake of professionally, but it's not on my priority list.

Any ways, was there a point of deciphering my protocol? Do you have some suggestions for it?

That's the idea of the next update. I'm also going to add a /list command, and a MOTD in the server config to display on user connection.

Mostly for fun; I might try to make a client to see if I can interact with your app, or a different server binding for a custom server like Spout.
Server console log prints out the colour code before messages.

I've got a question: Why is the key "53fl6"? Is there special significance to that?

No reason. It was a random string.

I know the server console prints out the colors, however if you use some Linux terminals the colors actually work (Like ROXterm and Lxterm).

This is very very nice, approved.

I have a question. Is the approved plugin going to appear on the bukkit plugin list of the forums, or in bukkit dev?

If this is going to appear in bukkit dev, I already have an accepted submission there.

Both.

I donated. Nice work.
I also have a suggestion. I would like to see a login function added. So people cant just join and make their nick to a staff members and make people think they are staff. Then the staff will end up opping a griefer. So a Login function would be awesome!
