I absolutely love this mod :) adds so much life in to a player village

As a feature request, could the Noticeboard spawn some sparkly vfx when it has new posts since you last looked at it? 

Something like, if Noticeboard last updated date > client last view date, spawn some particles

1.21 or 1.22 added some particle sparkles when you see a lore book / scroll and havent read it yet, so imo it'd be an intuitive addition.

I have some very very light VS modding experience and would be happy to try and help or attempt a Pull Request for it, if you approve of the addition.

A collab with BOUNTIES mod would be awsome!!

Dovaskus I mean since 1.2.0 the model is wall hangable. I could do a button for "bumping" notice up to top of the list.

Feature Request:

Notice Board UI:
- Could be good if you could select styles of board or customize "swimlanes" for tasks
- A way for someone to react to a notice
- The ability to drag and sort notices for prioritisation.
(most of this is probably too much damn work for what I'm asking so no worries)

Models: A wall hangable model for Taverns

Avem sorry it took so long, should be fixed in new version ^^

There seems to be an issue when using the notice boar where I cant scroll down far enough to see the final notice. It seems to happen with 3+ notices and the bottom most notice is cut off about half way in the UI and you cant read the full thing.

Using the notice board crashed the client who attempted to pin the first message, but after reconnecting there were no more crashes and it worked as advertised. Just letting you know! 

propaneko Everything appears to be functioning correctly for me now, thank you.

have you removed database before trying?

After removing database I've never experienced the error you have.

The issue still persists we had the same issue on our server any version of 1.2.x crashes players on connection and version 1.1.2 also seems to be broken as notes can be pinned.

Here the error on 1.2.x

Sekenneri Joulz HaMeRoN please check version 1.2.2 and let me know if it's still happening. Try to remove database file and restart server if it's still happening. Or post the crash log.

Sorry guys, gonna try to fix it asap.

Suddenly after the reboot, the server started throwing critical errors and everyone who tried to join was getting crashed. I had to remove the mod. Why did this happen?

Our server is also getting this game breaking bug. We had no choice but to remove it

For your information, I got the following error on attempting to post the first notice. I was able to post without issues after reconnecting and retrying.

propaneko Success! Thank you.

I love the design of this board so much — it’s incredible and fits the game’s style perfectly, maybe even too perfectly!

SalazarWindriver you can do it now in the 1.2.0 version. Go into creative mod, destroy the noticeboard, middle click on the board on the hotbar to clone it and place it somewhere else. Messages will be shared between two boards or more if you gonna keep cloning them. but it goes the same for everything, editing, removing too.

!!!IMPORTANT!!! Because of the database migration version 1.2.0 is not backwards compatible! When you update the mod to 1.2.0 do remap when asked and restart game/server. All currently placed notice boards should keep their messages.

Whats new in the 1.2.0 version?

• added wall mountable variants of noticeboards
• noticeboard can be moved without losing its messages and owner, to fully reset it recraft it in the crafting grid.
• added simple lock mechanism that can be turned on/off by the board owner
• better selection/hitbox values
• cleaning up code, refactoring some old things after learning much more about modding in VS

I am not sure what exactly is the problem but I am playing on a 1.21.1 server with this mod and whenever I post a notice on the board it crashes my game.

Is it possible to have an option to share posts on notice boards?  no one is going to travel to my area to read my board. And it is such a distance to travel to spawn, I'm never going to get around to the travel to put my post up where people can see it.  Even if it were a second board, it would be helpful for more spread-out servers

/EDIT  disregard, found the answer. NOT THIS MOD. 

I'm not sure why, but when we restart the server the message boards are blank. It's a pain to type in my notices again. LOL 

v. 1.21.1 server and 1.1.2 of this mod

verified it makes the db, but maybe it's clearing it on reload?

/EDIT possibly not issue on mod end, something might be clearing ModData, which would do it for sure... more testing and reading logs on my end.

propaneko

Everything appears to be working now, thanks for the update!

croweaver FatherSarge Hewholurks I've pushed a new version that is just a recompilation with .net 8 that VS will be using since 1.21 let me know if it still needs any fixes.

Hey is this going to be updated to 1.21? I ask because this is a delightful mod and I'm being informed by some people that its not but I rather just get it from the person actually doing the mod directly.

Def excited to try this mod out on the .21 server I'm making, current issue with the GUI I think (nbd, old method) causes crash when you try to open it up. Looking forward to an update, cool mod!

Currently crashes when notice board is used on 1.21.0-rc.1

Following Whiteshadoh message. I understand that the main idea is to let anyone rip or create posts on the board. But could be any chance or workaround to allow players to read but disable to create or remove?

Thanks for such a cool and creative mod!

Great mod. I use it to post about new updates on our server. Other players use it to advertise their shops.

Even though this mod is mainly meant for multiplayer rp, I've gotten good usage out of it in my solo world by using it as a sort of 'To-Do List' Board that I can check in game without needing to tab out of the game and check a list somewhere else. After finishing a few of the tasks and seeing the board become more empty is weirdly a good thing since it shows I'm making progress on my set tasks.

Whiteshadoh

That's the kinda idea behind notice board, everyone can rip the paper of the board right? Also some people would like to be anonymous and still leave a message, joke, propaganda, anything. So you can always at the end of the message put something like "- Whiteshadoh" if you want others to know its you.

propaneko
Two things:

Other people can remove and edit any notice. Would be nice to be able to only let the notice board owner able to edit or the person who left the notice.
There is no player name tag to the notices, so they are theoretically just messages from anyone or the same person over and over.

I might gonna try to figure out something with the "physical" placement of some parchments, but it might take some time as it's the part of modding Im still learning. And actualy not having proximity chat was the culrpit of crashes, but it's fixed.

Sorry for the late reply but we were using the proximit chat mod at the time. Strangely the proximity chat mod didn't make notice boards crash when we were playing on a lan server via hamachi

Can you please also make a mod that lets us put parchments on walls like signs for people to write notices and bounties
It would act the same as a sign on the wall, letting you write on it with visible text.
that would be an incredibly useful mod!

So far so good for rc1, I was wondering if you intended to add the ability to make the notes physicalized so that we could use it as a job board or a bounty board?

Not sure, but it should work just fine on 1.19.7 It's not that much of a difference between versions. StikShift4Life

Does it work on 1.19.7? Updating to 1.19.8 caused my friends an I quite a few issues on my server, so we've elected to stay on 1.19.7 for the time being.

ShubiMaja sorry it took this long, moved db file to the ModData directory, adjusted the config file directory and fixed some bugs that lead to crashes.

ShubiMaja

Sure, that's actually a good idea! Will change the db location to the ModData directory. Gonna try to do it today.

propaneko  

Thanks for the great mod! We really enjoy it! However, can you please properly store the data for your mod outside of the ModConfig folder and in ModData like other mods? Atm its difficult to release configurations because we have to watch out for the data stored in the configuration folder. Or at least give us an option in the config to change where the data is stored.

Related issue: https://github.com/ogaseb/NoticeBoard/issues/1

Yes, many. I have 140+ mods but I Don't think we have the Proxy Chat mod. Do we need it?

RosstheGreat are there any mods that you using or just Notice Board? I had this crashes only when I had clean VS game and didnt had proximity chat mod.

Hey, I also want to second CrimsonCount's error, we had this on an older version of the Notice Board. I will double check and see if we still get the crash after your update though.
Same issue, object not set to reference error

I think I fixed those crashes.

CrimsonCount By any chance, do you play with proximity mod or without?

I'm in the same server as Danny2703 and posting a message to the notice board kicks the poster from the server, but does leave the message on the board. We are playing on a dedicated windows server. I am unable to copy paste the error message printed in the console, but I've typed it out.
The error message in the server console is:
[Server Error] Exception: Object refrence not set to an instance of an object. at NoticeBoard.Events.ServerMessageHandler.OnPlayerSendMessage(IServerPlayer player, PlayerSendMessage packet) in C:\Users\Enelorin\Projects\NoticeBoard\Noticeboard\src\Events\ServerMessageHandler.cs: line 51 at VintageStory.Server.NetworkAPI.HandleCustomPacket_Patch1(NetworkAPI this, Packet_Client packet, Connected Client client) at VintageStory.Server.ServerMain.ProcessNetMessage(NetINcomingMessage msg, NetServer minSocket) in VintagestoryLib\Server\ServerMainNetworking.cs: line 138

In a multiplayer server. Kicks me whenever anyone pins something on it saying it threw the server an exception.

EbKeth hard to tell what is wrong, it doesnt look like an error that is from my mod.

I love this mod, thanks for making it!

I'm running across a crash when posting a new notice on the notice board:

Thank you so much!

Ah sorry my mistake I didnt create version with config, will do it soon Quiche

Quiche there is, on 0.5.0, you should have config `json` file in the noticeboard folder in ModConfig.
Also I was trying to add container slot to the gui, but I think it's too much for me for now. Have a lot of issues if it, fixing one brings some others. So I guess will leave it as it is for now. Maybe later I will give it another shot.

propaneko Thank you very much for looking into it!

Would it be possible to have a config for the distance the noticeboards proximity is? We have a quest inn that we'd love to be able to notify the entire town when it puts a new notice up, please.

Tbh, can't reproduce it Quiche

Accidentally double clicked a noticeboard on top of the other got this error and was kicked:

I was actually just looking for the new version, as my players are all offline

Editing feature seems to work fine.

WickedSchnitzel Its kinda weird you're getting this error while quitting the game, as this part of code is only fired when you send message.
 I have hard time to reproduce this issue. Remember to use newest game version. Origin_Alpha_43

When i quit the game:

I haven’t tested this in a few updates, but I last tested 0.2.2. and if this hasn’t already changed in the latest 3, a way to edit your notices would be good.

Thanks DeanBro ,will add it soon.
For anyone if you tested this mod and have any ideas how it could be further improved just let me know.

Hi propaneko

I created a translation for your mod

Nice update. I’ll be trying it out.

I've put more info, it's a bit chaotic for now.

Ok, some more info? How that works / craft etc.. ?

Quiche Thank you <3
Trying my best, it's my first time modding Vintage Story and also learning C# in the process 😅

Excited to see the development of this! Seems like a must have for RP servers <3

RuneScholar  Thank you! And yeah, this version is in very early stages of development, for now just for testing on our RP server, will add more stuff and make it  better with time ^^

This is such a great idea. I’d use it if I were playing multiplayer.
