Screen (slightly outdated):

--------------------------------------------------------------------------------------------------------------------------------
Features:
1. Filtering servers by various flags:

• - show/hide offline servers.
  - show/hide servers with incompatible version.
  - show/hide servers with incompatible NewGRF.
  - show/hide password-protected servers.
  - show/hide servers without any companies.
  - show/hide servers with no more companies available.
  - show/hide servers without any connected players.
  - show/hide servers with no more players available.

2. Filtering servers by map size and landscape.
We can choose a certain landscape and some common map dimensions from dropdown lists in the multiplayer server list window. "(advanced)" label means that we chose more complex filtering from "Advanced filter window". Advanced map size and landscape filtering allows to choose any map dimension range and any set of landscapes.

3. Filtering servers by dates.
This filter is accessible only from "Advanced filter window". "Dates" button in the server list window indicates that date filter is enabled. Clicking on it will open "Advanced filter window". We can specify a yearly ranges for game starting date, game present date and number of years the game is running.

4. Filtering servers by language spoken.
You can choose a flag from a dropdown list next to "Dates" button.

5. Filtering servers by name.
Server name must contain all words entered into filter editbox, but not necessarily as a whole words i.e. "sup ann" filter matches "Joannas Super Server" name.

6. Favourites.
You can add a server to favourites. A "favour star" is shown within favourite server. Also there is a separated list of all favourites.

7. Separation between LAN servers and Internet servers.
There are two separated lists for these two types of servers.

8. New column - favour indicator.
The "number of times played" bar is shown in this column. The longer the bar is the more times we played the game. Also a "favour star" is shown here. When we sort servers within this column they are compared firstly by "is or isn't a favourite", secondly by number of times played.

9. Removal of duplicated games.
Some servers use variable port number to host a game, these games appear sometimes as duplicated entries differing only by the port number. The patch merges duplicates into single items.

10. This patch doesn't modify network protocols (you can play on non-patched servers) or game save compatibility (you can save a game and load it later with non-patched OTTD).

@adf88: Really Nice Patch!!!
If this is implented in OpenTTD i don't need anything more in OpenTTD Multiplayer!!!
One Thing: Offline Server can't be showed because they are offline

[adf88]

One Thing: Offline Server can't be showed because they are offline

More precisely - servers that are not responding. In ottd they appears on the list as just an IP addres. "Game info" box says "SERVER OFFLINE"

[Bilbo]

Great idea for a patch. Hope it'll make into trunk soon.

Offline servers can be shown (you see their IP), though no info about them is shown because no info is available for them.

In future I think the idea may be extended by more advanced filters (by climate, by map size>X, map size<X, by specific server settings (I hate servers with "original" train acceleration model)), though that would make perhaps enough code for another patch :)

Also, it will probably need small update of network code to be able to get these settings from server without connecting to it (or it is possible somehow?).

Comming soon (take a look on my firs post, after attachments).

Yes, that would be a great feature. But cant code this myself. Its my firs approach to ottd development. I was just annoyed at hardness in looking for proper server so I wrote these few lines of code (less then 100 ).

But who knows, maybe in feature...

[Roujin]

Looks great! I'm happy about every new use of the filter framework (guess why ), and this seems to be a very useful addition.

May I suggest to base the patch against current trunk instead of 0.7.0? It may need rewriting the GUI part to match the new widget system (depends on if it has already been done for the server list window); anyway at some point it will be needed.

Actually it doesn't use the filter framework.

It furthermore hardcodes strings making it impossible to translate and it makes the window wider than the default resolution.

Well, shame on me for only looking at the screenshot, not the code
Then, aside from basing against trunk instead of 0.7.0, please use the existing framework for filtering of GUILists. You can look at the content list (src/network/network_content_gui.cpp) for an example how it's done. It's somewhat similar to sorting.
edit: the changelog for (svn r15372) could be of help

About the hardcoded strings, well I guess he's planning to use icons instead of them in the next version...

[adf88]

Unfortunately, it doesn't use the filter framework.
In the beginning I planned to use it, even started coding. But after few lines of code I realised that it is useless. The reason was that there is only one filter function (based on various settings) and it's always activated. Secondly, applying filter entails rebuilding the list and vice-versa so it was naturally to put them together.
To make use of filter framework I would have to separate filtering between set of functions. IMO that would be unhandy because in order to apply filtering I would have to switch between these functions and call them one by one (through Filter method).
The problem is that your framework is directed to using one filter at time. It would be useful if you change that, change
SetFilterState(bool state){...}
SetFilterType(uint8 n_type){...}
to
ActivateFilter(uint8 n_type){...}
DeactivateFilter(uint8 n_type){...}
you know what I mean ...
I searched whole solution and didn't found any usage of filter framework so a thought that it is not completed yet .

May I suggest to base the patch against current trunk instead of 0.7.0? It may need rewriting the GUI part to match the new widget system (depends on if it has already been done for the server list window); anyway at some point it will be needed.

I didn't know it exists Its my second day of ottd developing. I'm glad that you are directing me to right path. Currently I'm finishing "map size" and "landscape" dropboxes, but I'l take a look with pleasure on the new widget system. I hope it has more object-oriented drawing and interaction (these OnPanit and OnClick overload ... this should be automated).

It furthermore hardcodes strings making it impossible to translate and it makes the window wider than the default resolution.

This is temporary.

A slightly more complicated filter usage you can find in the filter sign list patch I have written (see link in my signature). There it has a button for if it should match case or not when it filters the sign list for a string.

The filter sign list patch makes use of the filter interface.

[jonty-comp]

Excellent! I think a patch like this is really useful. There are generally well over 100 servers nowadays and it's often quite difficult to find the one you're looking for if you don't have a direct-connect IP/host.

I even tried to do this a bit myself, but gave up after deciding OpenTTD was not the best project to learn C++ on.

[adf88]

New version released (0.2)

[Eddi]

If this is implented in OpenTTD i don't need anything more in OpenTTD Multiplayer!!!

by my experience, that kind of statement is never true. as soon as something is included, it will be old news, and people will cry for the next new thing.

PS: it's "implemented", and it's probably the wrong word at this point.

[Bilbo]

I tried your patch and GCC compiler seems to be complaining about errors when compiling:

Code: Select all

[SRC] Compiling network/network_gui.cpp
/home/bilbo/p/openttd/0.7.0/src/network/network_gui.cpp:968: error: ‘_network_game_window_widgets’ was declared ‘extern’ and later ‘static’
/home/bilbo/p/openttd/0.7.0/src/network/network_gui.cpp:175: error: previous declaration of ‘_network_game_window_widgets’

Well, "static" and "extern" does not mix well together.
Either drop the static in the _network_game_window_widgets declaration or move the declaration up to the place where you have the extern now.

[adf88]

I moved the declaration. Now it's fine.

[Telordya]

I replaced the openttd.exe with your patched .exe and I receive this popup error message when I execute it:

[Eddi]

you need to replace ALL files. not just the .exe, the .lng files, too.

[Telordya]

Ok, but the .zip file only contains openttd.exe, there is not .lng files. Did I miss something?

[Eddi]

then the uploader made a mistake in not adding them, they are essential. at least english.lng must be included, better all of them.

[petert]

Tell me if I am wrong on this but...
What's the point of this patch if the compiled version can't join multiplayer servers?
