Tools and tips of BGA Studio

Server Tools and Tips

Starting a game in one click

To start a game:

• Create a new table with your game.
• If you want to play a game with 3 players, specify that you want a maximum of 3 players at this table.
• Click on "Express Start".

Stopping a game in one click

• Click on the "quit" icon on the top right of the screen.
• Click on "Express Stop".

Switching between users

When running a game on Studio, you can use the little red arrow near each player's name to open a new tab with this player's perspective.

Access to game database and Logs

At the bottom of the game area, there is section without a title containing 3 useful links:

 Go to game database • BGA request&SQL logs • BGA unexpected exceptions logs

• "Go to game database" link is an immediate access to the PhpMyAdmin tool to view/edit the tables of the current game
• BGA request&SQL logs - link to your studio PHP log - all tables, all severities. Anything you print using debugging and tracing functions from PHP and some framework logs
• BGA unexpected exceptions logs - same log as above but only severity warning and higher

See [Practical debugging] for more info about it.

Save & restore state

Using links of this section, you can save the complete current (database) state of your game, then restore it later.

This is particularly useful when you want to develop a part of the game that is difficult to reproduce: you just have to save the situation just before, and then restore it until this part works fine.

We provide you 3 "slots": 1, 2 and 3. This way, you can save 3 different game situations.

Limits:

• the "restore" function does not work anymore when the game is over.
• a saved situation from a given table cannot be restored in another table.
• when you "restore" a situation, the current browser page is refreshed to reflect the updated game situation, but you have to refresh you other tabs/pages manually.

Input/Output debugging section

This section shows you:

• The AJAX calls made by your game interface to the game server. AJAX calls (outputs) begins with ">"
• The notifications received by your game interface. Notifications (inputs) begins with "<".

Note: if you click on some notification title, you can resend it immediately to the user interface.

Run PHP functions from the chat

On BGA Studio, you can directly run a PHP method from the table chat.

For example, if on your PHP you have this method:

  function giveMoneyToPlayer($player_id, $amount) { ... }

You can call this method directly from the chat like this:

 giveMoneyToPlayer(2564,2)

Note: this is not a real php statement, you cannot use self::, you cannot use ";" at the end and you cannot use quotes, if you need to pass a string skip the quotes, like this

 giveToActivePlayer(money,2)

Stopping Hanging Game

If game is hanging and you cannot enter it to stop you can type this URL (replace 12345 with your table number), which should bring you to a place where you can stop it without entering:

 http://en.studio.boardgamearena.com/#!table?table=12345

Desktop Tools

Eclipse For PHP Developers

Eclipse PHP package can be starting point for development you need. You may also want to install Tern JS plugins to understand dojo style JS. All desktops. https://projects.eclipse.org/projects/tools.pdt

Visual Studio Code

Microsoft Visual Studio Code is light weight IDE/Editor. All desktops. https://code.visualstudio.com

Gedit (Ubuntu)

Edit TPL To edit TPL with HTML code highlightings in Gedit under Ubuntu:

find gtksourceview directory in /usr/share, depending on your version (2.0, 3.0,...).
Here it's 3.0, then type in a terminal window:

    sudo gedit /usr/share/gtksourceview-3.0/language-specs/html.lang

then find 'globs' section, and change:

    <property name="globs">*.html;*.htm;*.tpl</property>

File Sync on Windows

Install WinSCP. Map a remote directory to a local one and enable continuous sync (one way). You need SFTP password you get when you registered dev account.

File Sync on Linux

• Option 1 - Nautilus (file manager)

You can just use Nautilus "connect to a server" function with URL sftp://1.studio.boardgamearena.com Then you'll get a mounted local folder mapping your studio folder and you can use any editor you like without further need for sync. Downside - if connection goes down you cannot work on source code, no local copy.

• Option 2 - sftp and rsync

#!/bin/bash
BASEDIR=`dirname $0`
REMOTE=$BASEDIR/remote
LOCAL=$BASEDIR/workspace
GAME=mygamenamehere

#mount remote
fusermount -u $REMOTE #this unmounts dir
echo LongDevPassword | sshfs -o password_stdin myusernamehere@1.studio.boardgamearena.com: $REMOTE


#this starts auto-sync from local to remote mount
killall lsyncd
lsyncd -deplay 1 -rsync $LOCAL/$GAME/ $REMOTE/$GAME

This can be able run on startup, so you don't have to do anything manually. However sshfs is not very stable you have to kill and restart it sometimes. And remote goes away sometimes due to connection issues with studio. In this case its handy to have a local copy.

You can also sync on demand (from a build script or editor command) using

rsync -vlrt $LOCAL/$GAME/ $REMOTE/$GAME

Debugging

Browser is the best tool for debugging, see Practical debugging for details.

Version Control

Studio providers svn for you code on server, however there is no way to access history, restore or do anything with it unless you ask admins. If you want to keep your code in another repository. I suggest to use git with local repo, which you can sync to cloud or backup.

PHP CLI

Its handy to have php cli (command line) tools install to run php locally, so you can test some stuff without deployment cycle.

ImageMagick

Handy set of image manipulation command line tools, useful to for example to stitch together bunch of images and re-size, to use as sprite (in Stock component for example). I.e. you got a graphics file from publisher where every time is 600x600 PNG file with every time in separate file. You want .jpg instead of .png to make it not like 20Mb, all images in one column with size 128x128

/usr/bin/montage  `ls Tiles*.png` -tile 1 -geometry 128x128+0+0 ../out/tiles128.jpg

Client Tips

Speed up game re-loading by disabling Input/Output debug section

Development UI have few sections for debugging only, such as 'Input/Output debugging section'. Loading this data will significantly slow down your reload. I did some profiling and my reloading (i.e. F5) took 14 seconds, 12 of which it was dealing with loading this section. If you not using it you can disable it. In your JavaScript code, in the begging of 'setup' method add this code

        dojo.destroy('debug_output');

That should get rid of this section and overhead associated with loading it (it may have some other side-effects, I have not explored all of them)
