-Quick Game for Toronto Perl Mongers +SDL RC 2.5 decides to play with PDL
-
-
+PDL provides great number crunching capabilities to Perl and SDL provides game-developer quality real-time bitmapping and sound.
+You can use PDL and SDL together to create real-time,
+responsive animations and simulations.
+In this section we will go through the pleasures and pitfalls of working with both powerhouse libraries. -- David Mertnes
-So I am preparing a presentation of the new SDL perl for February's Toronto Perl Mongers meeting. What better way to so off SDL perl then with a game?
-I started hacking a small point an click game a few days back. I really didn't have a idea in mind, but I did have a goal. I wanted to make a game that shows the basics of a game in SDL. Drawing to screen, game loops, physics and so on. I think I have accomplished it so far.
+
+PDL's core type is a piddle.
+Once a piddle is provided to PDL it can go do a numerous amounts of things.
+Please see the example in 'examples/cookbook/pdl.pl' in github.
-Take a look at it here. Download that and call it[Shooter.pl]. To win click the balls.
+
+First lets get the right modules.
-To play this game you need the following:
+
+Suppose you want a surface of size (200,400) and 32 bit (RGBA).
-
-I will put up binaries soon-ish.
+
+Define the $width, $height and $bytes_per_pixel. Your $bytes_per_pixel is the number of bits (in this case 32) divided by 8 bits per byte. Therefore for our 32 bpp we have 4 Bpp;
-It is a playable (albeit hard) game right now. All 7 seven levels of it. The purpose of the game is simple click the balls to win. Sounds easy but it isn't. You also get a time in milliseconds after each level. Share your scores on here! I will leave it up to you guys to be honest.
+
+Create a normal $piddle with zeros, byte format and the Bpp x width x height dimensions.
-I do have to tidy it up and right documentation for it. This way I will be able to present it clearly to my fellow mongers. I am also still looking for ideas to make this a more polished game. FROGGS recommend I make it a classic NES duck hunt game. I thought since I am using gravity I could do a UFO game out of it where you shoot the UFOs. I am open to your ideas.
