Many updates, everywhere

The news title says nothing and everything :-).

After an PHP update the syntax plugin doesn’t work anymore. I added a better plugin and updated all chapters to display code in a reader friendly way. I also removed the description how to copy source code using the old plugin in the introductory chapter. I adapted code snippet length in some chapters (Chapter 4, Chapter 15). Updated Chapter 18 about music and sound.

I added a new SDL2 powered Free Pascal project: SuperSakura. It’s a nice visual novel engine to run retro-style Japanese games by Kirinn.

I updated some chapters (Introduction, Windows Installation, Linux Installation), mainly because of the repository change to the PGD Community SDL2 units. The units got a lot of updates lately, and help is needed to improve them even further. While this news post was waiting to be published, it appears Tim is back. Now, we have the unfortunate situation that there are two active repositories for the SDL2 headers and the situation has not been resolved, yet.

Also, I changed some stylings.

Important: New SDL2 Repo!

IMPORTANT: The repository to get the newest, up to date, SDL2 units has changed. It is found here: https://github.com/PascalGameDevelopment/SDL2-for-Pascal. It is now hosted by our Partner site Pascal Game Development, where you can find many resources if you are interested in game development with Delphi or Free Pascal.

Background: The old repository by Tim Blume has been an up to date source for these units for many years since its establishment (Thanks Tim!), but lately no more pull requests were integrated and so a new repository maintainer had to be found. Long time contributor to the units, Super Vegeta (suve), came up with the great idea to integrate it to the PGD repository, which is now reality (Thanks AthenaOfDelphi!).

What now: Please, if you are a Pascal SDL2 developer, pull from, commit to, fork and star the new repository over at https://github.com/PascalGameDevelopment/SDL2-for-Pascal and update your links accordingly. ūüôā

Updated the Linux installation chapter. Now you can get the environment running rather quickly.

Added a new widget “Quality Pascal Articles” (right sidebar) where I add carefully chosen Pascal articles, I appreciate.

Keyboard and Key States Chapter added

Added a new chapter about the keyboard state and the key states for simple key input handling. Updated the Text and Font chapter.

It seems the author of p_daniel’s (or danpla’s) SDL 2.0 units has deleted his github account (EDIT, 06/10/2019: The user name got changed.), hence I updated the discussion page about which unit to choose. Also the official website of the Bare game project seems to be offline. Thanks for the hints St√©phane.

A new impressive, commercial SDL2 based Pascal project called Savage Vessels has been added to the project list. The project list itself got restructured for better readability and loading times.

SDL2 Tutorial Improvements

I did a major update to the whole SDL2 tutorial, added some new, restructed and split up many old chapters to have a better learning experience. Instead of ten big learning chunks, there are now 18 smaller chunks which are dedicated to clearly outlined topics. I’m looking forward to do a lot of fine tuning and extending the SDL2 tutorial. If you find errors, just drop me a line.

Every article now shows a date of the last update. This makes it easier to estimate how up to date the article’s information are.

I decided to change the basic font size from 18 to 24 points since the text appears too small on common high resolution displays. I adapted point sizes for other elements accordingly. Also, I made license information available for many images (CC-BY 4.0).

The drop-down menu is gone since it got too long and it has been hard to reach all entries on some devices.

Thanks to MattCash Chapter 6 got some necessary updates.

About SDL2, Free Pascal and… Android

Since the rise of SmartPhones, many wonder if Free Pascal/SDL2 development  is possible for them, too. The good news is, yes it is possible! The bad news is, it is kind of toilsome to set up a development environment for Android (one of the two major operating systems of many SmartPhones).

Imants Gulbis informed me that he set up a Lazarus package (LazSDL2Design) which makes development of SDL2 applications with Free Pascal for Android fairly simple and integrates with the Lazarus IDE. Check out the instructions to make Lazarus/SDL2 ready for Android. The LazSDL2Design package relies on an own translation of SDL2 headers (LazSDL2) by him.

I put together some useful resources for Android development in the FAQ.

Thanks to reader Paul for letting me know about an unclear statement in Chapter 8 Part 1.

The website uses HTTPS now.

Linux Tutorial News Cover Image

New Linux Installation Chapter

A new Chapter 2 has been added. In contrast to the classical Chapter 2 which explains the installation of SDL2 and Free Pascal for the Windows operating system, the new Chapter 2 explains the installation and configuration of SDL2 and Free Pascal/Lazarus in Linux. Initially I was trying to check for some troubles which got mentioned. Finally I ended up with a short, new installation chapter. A few minor changes have been added to the other chapters which are basically hints for Linux users.

A few new great and interesting Free Pascal/SDL projects have been added to the project page. These are namely GearHead: Arena, GearHead 2, Dungeon Monkey Unlimited, Monsterland and DoomRL. The former three are open source by the way.

OpenGL Logo

SDL 2.0 meets modern OpenGL

Good news, Chapter 10 has been released right now! You ever wondered what to do if you would like to create 3d graphics for a game or application? – Well, you go for modern OpenGL. And SDL 2.0 is probably the best and most convenient way to go for modern OpenGL nowadays, even professionals typically use SDL as powerful assistant for their OpenGL applications.¬† Learn more about the strong relationship between SDL and OpenGL in Chapter 10. – And learn how it’s done, of course ;-).

Chapter 3 got a short explanation now on how to copy the source code of a chapter. In the SDL 1.2 chapters the source code¬† was shipped for each chapter as Pascal file. Nowadays it is much more convenient to grab the source code (or just the desired parts) by copying it directly from the chapter’s source code boxes (in the browser) and paste it whereever it is needed.

The transfer of the old website has been finished. Nearly the complete content is in some way or another transfered to the new page. For example, all tutorial pages (even the old ones) are still available. Some downloads are integrated at the corresponding tutorial pages now, so they are not lost. Some pages are gone, these are Downloads, Tables and Links. These pages are of no benefit anymore since their information are now provided at the corresponding place instead of separate pages. Nevertheless, links trying to access these pages are redirected to the main page to prevent broken links.

No One’s Space got greenlit. This means that this Free Pascal/SDL game will be available in Steam for purchase soon. It demonstrates the power of Free Pascal and SDL.

Small update of some subdomain settings. Subdomain links work again.

No One's Space

Commercial Free Pascal/SDL Project

The No One’s Space SDL game has been added to the SDL Project page. It is the first commercial title added and Klaus Vor der Landwehr (from Turtle-Games) has kindly provided an interview for us. Feel free to support the game in the greenlight state over at Steam. This game demonstrates that Free Pascal and SDL make games of commercial quality possible.

The installation instruction got extend by an explanation how to install and configure Lazarus.

Pascal SDL Projects?

A new page has been set up which gives an overview of projects done in SDL with Pascal (any dialect). The projects may be games, interpreters, libraries, anything. Of course SDL should play a key role and shouldn’t be just used to set up an OpenGL window (or similar). If possible I try to have an interview with the creator of the project.

The first project listed is the famous EGSL project and its successor Pulsar2D. Both have been created by Cybermonkey who kindly gave an interview and provided a lot of screenshots to me.

Feel free to contact me to let me know about other Pascal SDL projects.

Edit: As of 09/02/2016 I added suve’s Alexland and Colorful to the project page. Thanks for the interview and the screenshots.

Chapter 9 application preview

New Chapter 9 about Music and Sound

The new Chapter 9: Music and Sound has been released. It demonstrates how to use the SDL_mixer 2.0 to load music and sound files to use them in your applications.

I was surprised to find that there have been made many important updates to Tim Blume’s SDL 2.0 units since the latest release (version 1.72). This means for everybody who relies on these units, update to the latest master branch release (later than version 1.72)!

Download ZIP button
IMPORTANT: Get the latest master branch release! Download Link

Otherwise you will struggle to get some important sdl features. E.g. key code constants and the code of the new Chapter 9 won’t work. I adapted Chapter 8 about event handling.

An interesting new header translation project was mentioned to me which allows for dynamic loading of SDL 2.0. Check out Chapter 1 to read more about this project by Imants Gulis.

Many smaller updates have been performed, too. Also the color scheme has been updated since it was stated that the contrast of the former color scheme has been too weak. You may also have noticed the amazing new fractal title background image :-)!

Important hint: The Free Pascal compiler got a new stable release on 25th November of 2015, version 3.0.0. Don’t forget to update your favourite compiler :-)!
