Highscore Tutorial

One of the little things for a nice Flash game is a tutorial. It's making people to go back to your game and play it again to win from the competition. It's a way of competition and interactivity between the players to do their best and win as much points as they can.

Things you need
1. A webserver enabled with PHP and MySQL. Almost all unix/linux webservers have these two, because they are free for everyone. If you don't know if you have PHP4/MySQL enabled, contact your Hosting Company.
2. Notepad. Or a similar text editing program.
3. A FTP program to upload your files. CuteFTP or WS_FTP are two examples.
4. The files that come with this tutorial. (highscore_tut.zip)
5. Your nice Flash game. Duh..

The first few things.
Open '_data.php'. This is rather important. You need to change a few things here. You need to input the right usernames/passwords/game name/other things. You will have to change at least numbers 1 to 6. The numbers 1-3 are the few things you need to enter to make contact with the MySQL database. You've got those from your Hosting Company. If not, ask them. 7-14 are optional, they don't need to be changed to get it all working. All things are rather straigtforward.

Upload _data.php/get_score.php/install.php/new_score.php to your website's root directory. Run the install.php script. When it sais 'Done..', you can delete the install.php file from your website. Done.

Why PHP/MySQL? PHP, PHP Hypertext Processing is a free server-based scripting language that is free and provided by a lot webserver/hosting companies. Other than that, it's a very fast language, faster then ASP(from Micro$oft). MySQL is the perfect database partner for PHP. Together they can be fast and above all secure.

Adding new people to the scores.
Ok, now we are going to start with the Flash part. When you want to send your highscores from Flash to the MySQL server, you'll need this Actionscript:

	
_root.add_pass = "{same as $pass in _data.php}";
	_root.name = _root.variableYouUsedInTheGameForThePlayersName;
	_root.score = _root.variableYouUsedInTheGameForThePlayersScore;
	getURL("new_score.php", "", "POST");

That's it! The PHP script itself makes sure the player gets added to the database and all other things you don't need to worry about.

Showing the Highscore in Flash.
This is rather easy. Make 10 variable text boxes in a column.(Or the number you used in the _data.php file as $st_size.) These dynamical text boxed are named 'name1' to 'name10'. (Or different, again corresponding to the Standard Size inputted in _data.php.) Then make 10(Or blab, bla, you know..) dynamical variable text fields next to each corresponding text box called 'score1' to 'score10'.

I am not taking this anyfurther, but you can understand that you can make the looks of your Highscore list somewhat nicer than standard.. ;)

Now use the following Actionscript code to load the variables from the database back into Flash:

 	   loadVariablesNum("get_score.php?flash=1", 0);
Now the variables get loaded into the _root. But if you have your Highscore list in a movieclip, you should use this code:
  	   loadVariables("get_score.php?flash=1", "_root.scoretableOrAnyOtherMCname");

The location of the Flash game's SWF file and the location of the Highscore scipts must be at the same domain. (And in these Actionscript code, it must be in the same folder as well.) This is a standard security feature from Macromedia Flash. It can't be changed, live with it.

Including the Highscore list on your webpage.
It is possible to include a HTML highscore list on your webpage. This is realy nice for your site's visitors.

Your page where you want it to show must be a PHP page as well. We take 'index.php' as an example. The $dis_file variable in _data.php must be the same as this page. Now, where ever you want the Highscore table to appear on your page, you include this:

	

You can change some graphics from the HTML table in _data.php if you want, but look out to only use ' in the code instead of ". That is VERY important.

Ending
Well, that's about it. You can use this to make your own nice Highscore for every game you want.
