New game made with Allegro.pas

Lazarus user Handoko has made a demo game for the Lazarus' Graphics Contest 2017. He also plan also to write a tutorial explaining how the inners of the game works and how it uses Allegro.pas.

Right now I'm negotiating the possibility to use the game as one of The Demo Game for the Allegro.pas 5.2 branch.

Allegro.pas 5.2.a3 released

It was a long time ago since the latest release. More than a year. And I've done a lot of improvements to it, so I've released a new alpha version (the 3rd one).

Despite it is still an alpha version, it is quite stable. Please visit the Files section to download and test this new version that fixes bugs and adds new functionality and more examples.... read more

Updated on-line documentation

That's it. I've updated the on-line documentation with the current svn-TRUNK one, wich is much better than the one included in the last package. It now includes much more information, some fixes and a search engine.

You can't download it at the moment but you can read it here.

Allegro.pas tutorials

As some people has asked for, I've started with Allegro.pas tutorials in the Lazarus/Free Pascal wiki.

Some body asked me for Spanish tutorials, and also it's more easy for me to do it in Spanish, so I'll write them initially in that language. I plan to translate them to English ASAP, but if some body can do it for me it would help a lot. ;)

Any comment and suggestion are welcomed.

Fix version 4.4.5-1

Thanks to a note at the Discussion forums, I did some fixes and updates to version 4.4.5. They're a few, and mostly on the alwin unit. Actually I'm not sure that it works perfectly, but it compiles.

I've also updated the documentation, adding a search engine (actually just added an option to pasdoc). You can read it online or download as you wish.

As always, you can download from the download page.

Allegro.pas 5.2.alpha released!

About 3 years after 5.0.alpha, a new release of branch 5 (now TRUNK) was released today. It has a lot of improvements, and should be slightly more stable than previous alpha. You can download it from here. Any feed back is welcome.

I'll use it in the comming TINS 2016 contest, and I plan to use my entry as demonstration game for the library.

Allegro 5.2.0 released

Yesterday, Allegro 5.2.0 was released. I tested it and it's quite nice. It fixes suff from 5.0 and adds new things, like the new 3D API that avoids the need of OpenGL or DirectX. It is much like the 3D routines used in pre-5 versions but using hardware acceleration.

So, Allegro.pas TRUNK will drop 5.0 support and go to the 5.2. Actually I want to release a new beta before TINS 2006, announced by Amarillion few days ago. This is, before Friday May 13.

Free Pascal 3 and a possible new demonstration game

Few time ago, Free Pascal version 3 was released. Sometime later, Lazarus 1.6 was released. I didn't test them 'till today, and I found a few issues. They're not major issues, just some warnings here and there. So I did a few changes and uploaded to the SVN.

On the other hand, I was thinking about what demonstration game to ship with Allegro.pas 5 branch. I was thinking in an old idea: first person snowball battle. So may be I'll create a prototype using version 4.4 then port it to version 5.0 (or may be 5.1).

To GIT or not to GIT

Note: This was published in other of my current projects: Gesbit.

Some days ago, Leo has posted a comment asking why does Gesbit stay in SourceForge. I answered that I know that GitHub is the trend and SourceForge have a bad reputation, but I prefer SVN over GIT and SourceForge did work for many years.... read more

Version 5 becames TRUNK

As I said in previous news, I've moved the TRUNK to BRANCHES/4.4, then moved BRANCHES/5.0 to TRUNK. So now TRUNK is version 5, and a new beta should be released next year.

This doesn't mean that development of version 4 is finished. I'll update version 4 if necessary, fixing bugs and adding stuff if I find it useful. Also, if somebody send me patches, fixes and addons, and they fit the project, I'll add them too.

Version 4.4.5 reseased

I've finally uploaded stable Allegro.pas 4.4.5 version. It is a major update
of the library, but the first two version numbers are keept to be coherent with
original Allegro Game Library.

This version has some API modifications, as well as a lot of improvements that
makes it faster (and sometimes smaller) executables. Most important changes
from version 4.4.4 below:

  • New functions and procedures that detects system stuff at runtime, an
    new units for Windows and UNIX specifics.
  • New BOOLEAN type that allows better integration with library.
  • Use of ARRAYs and VAR/OUT on parameters, that allows to reduce executable
    sizes and faster execution, and a side effect is reduction of HINT and
    WARNING lines while compilation!
  • Several bug fixes in demo game, al_apply_matrix_f and al_pack_fseek
    functions and in examples.
  • A lot of changes on documentation.... read more

On-line documentation on-line again

I was working on next release (yay!) when I found a big stupid mistake: on-line documentation wasn't available! So this is fixed and on-line again, both versions 4.4.4 and 5.0.alpha1.

And yes, I want to upload new release 4.4.5 as soon as possible. It taked too long because alwas I have something to do. I'll try to release new versions in less time (may be tagging them with beta, RS and so) in the future.... read more

Next release

I was planning a new release, the 4.4.5 . I think it will be a "beta" or a "release candidate", not sure. Right now I'm working on the new GUI add-on, as it would be the base for the GUI add-on for version 5 too. I'm not sure, but I want also to add more MIDI and sound support (streaming), as well as another game demo that would be ported to version 5 on the future, but it may be a lot of work. Anyway, SourceForge is working on the severver and SVN and download doesn't work right now.

Still working

I know, not news, no releases... But I'm working on it.

I was working in a new GUI system, using Object Pascal classes. Currently it's an add-on but I think it should replace the current ugly GUI system.

Also I'm aware of some bugs and new stuff and improvements.... read more

New member in team

A new member joins to the Allegro.pas developer team. Gregor A. Cieslak, who yet created a fork to add Delphi support to Allegro.pas 5. You may remember him from previous messages. He will be responsible of main development of version 5, while I'll be responsible of maintain version 4.4 and (of course) help him with version 5.

Also, I've updated both Feature Requests and Bugs. We'll try to keep it up to date, so you'll have a way to see what's moving in the project.

Working on version 5.alpha2

That's it. I'm working on next version of Allegro.pas.

This new version should be Delphi compatible (Delphi 6 and up or so) thanks the help of Gregor A. Cieslak who did a fork that I'm now trying to merge with the new one. You can download and test his work at .

The new version will have more examples too and some bugfixes (I hope).

It has no ETA. At the moment you can get the updates from SVN (

Amazing Tetris

Lars Sonnen, Matthias Müller, Michael Willems and Markus Wall have published a new Tetris clone named Amazing Tetris. Of course, it uses Allegro.pas. They created it as a Computer Science project for school, and they helped testing and providing the OGG/Vorbis loader for Allegro.pas that I added as an add-on to the library.

If you are a Tetris fan then you know that not all Tetris clones are the same. Amazin Tetris has some nice features, as a "hold" place, a shadow to show you where the piece will fall and it shows the next 3 pieces. There are also different game modes, and you can customize the game adding music and backgrounds that can be animated!... read more

Version 5.0 Alpha 1 released

I didn't work on the project lately, but I decided to release an Alpha version (pre-beta) because it's pretty stable. I've tested in several systems (Xubuntu 32 bit, Fedora 64bit and Windows XP 32 bit) and it works... almost. It doesn't include full documentation, and it may not work properly with your system, but it has the new Allegro API and has OpenGL support and other new features.

New SVN repository.

I've just finished to migrate the SVN from the old repository to the new one. If you're using SVN to update your Allegro.pas copy, you should use the new repository (obviously). Visit the SVN section (see links on the left bar) to know the new URI.

New website

I've uploaded the new website. As you see I've drop the GesBit blog engine and use SourceForge's news service. That means that news can't be commented. Also phpBB service was closed too. Anyway, you can made any comment or suggestion using SourceForge's Discussion. Also I visit Pascal Game Development quite often.

The new look was made by José Francisco Arévalo, A.K.A. Paco.

Project updated

This is just to get used to the new SourceForge's project administration software. It looks pretty nice and easer to use than old one.

BTW, yesterday I uploaded new Allegro.pas package (4.4.4).

Allegro.pas 4.4.0 (stable) released

I've just uploaded the first stable version of the Allegro.pas game library. As some of you know, this library is a wrapper of the Allegro game library, so you can use this great library with Free Pascal and Lazarus.

I've fixed few bugs, added new functionality and create two new examples, one of them exclusive for Lazarus. Also I've revised the documentation partially. Remember you should update Allegro also because the most recent versions fix a lot of bugs that affects Allegro.pas (i.e. sprite rotating, textured 3D polygon renderer, etc.).... read more

Hello people.

I'm sorry because I didn't answer your latest questions from the forums. I was busy the last months and SourceForge did change his web site and didn't warn me about new messages. Don't know if it was a bug or that I didn't configure my account correctly.

Right now I'll answer your questions.

About the project, I'll release a new version with few bugfixes (very few ;)). Then the project will be in hiatus for a while (may be a long while) because I want to do other things, including to use Allegro.pas to create games but also other projects. Of course I'll fix any bug I find and consider any suggestion or code you send to me.... read more

4.2.3 beta and 4.4.0 alpha2

I've just uploaded two new versions.

The 4.4.0 alpha2 is the current development thread, and included some new features.

The 4.2.3 beta is released because some of the improvements from 4.4.0 are effective on that release, and 4.4.0 isn't compatible with Delphi.
