is it possible to make a DLL and connect to mySQL from Game Maker?
i dont think it would be possible to connect mySQL directly with scripting in gm...

Yes it is very possible with a tool called MySQL++. And programming for MySQL in C++ is also very easy. The only problem is, as far as I can tell, you must buy a license to distribute a DLL using MySQL++, which costs a lot of money. I'm not sure, since their statement is a little ambiguous and they never emailed me back when I asked them about it.

hmm then its possible to connect mySQL from gm like java huh
but java has its own mysql-connector plug-in ...
well i think i could make a DLL for it if i had delphi...

so i guess nothing is impossible except skating thru revolving door

I did a little bit of web reading on this. There is a DLL distributed with MySQL called libmysql.dll, that allows you full access to the API. The only problem with using it in GM is that it expects a lot of structs and other datatypes that GM doesn't support directly.

There is also a Delphi interface to libmysql.dll that might be a good area to check out. Using Delphi and this wrapper, it may be possible to expose some functions to GM that wouldn't require complex data types.

To Haxor: I wouldn't worry too much about licensing issues with dll distribution. Is your game going to require that they download and install MySQL in order to play? I think something like this would be more suited to a dedicated server than distribution to end users.

Edit: Oh, I forgot you can connect to a MySQL server over the internet. Never mind.

PHP scripts can access a MySQL database, and Game Maker can run scripts on webservers with the execute_shell() function. Just install the scripts on the server and call them from your game. No DLL nescesarry.

Reading would be a little more difficult, but doable.

If they are goin to have to download MySQL then you can just use the command line MySQL program since it returns values and GM can handle that.

This is, however, very insecure and practically opens your database to anyone who wants to mess with it.

How is it any different than a web page that uses PHP scripts?

[Richard]

Does a web page using PHP scripts to work with a MySQL database usually provide an easily accessible URL via which anyone can have the script update the database? Your game would have to pass the script some information for adding to/editing/removing from the database, and anyone could easily pass their own information.

That's assuming the game wasn't passing the script the username and password. If it was, it'd obviously be even more insecure.

And I'd add .. it's relatively simple to find what page your game is accessing. execute_shell() opens a new IE window. DT's browser embedding DLL would be a more secure method, but again simple to find out through I.E.'s history or with a packet sniffer.

well i  think i could make a DLL for it if i had delphi...

I think you can get Delphi Personal Edition for free if you search the web.
You can also get it in computer magazines.

[neonsoulstealer]

You don't need a DLL. MySQL tables and libraries are largely based on Perl, so I would learn Perl before going foward.

EDIT: Wait, what do want MySQL for anyway?

Smarty has a dll for connecting to a mySQL database

i think there is a newer version of this somewhere in the 'Extending Game Maker: DLLs, Scripts, and Libraries' section.

What the hell? This topic is over 2 years old? Why would you do that?
