Hi,

I would like to announce a release of Castle Game Engine 4.0.0, an open-source cross-platform 3D game engine for Object Pascal (only FPC/Lazarus):

http://castle-engine.sourceforge.net/news.php?id=release-4.0.0

I'm letting myself post an announcement to lazarus and fpc-pascal mailing lists, as this engine release is really directed at ObjectPascal developers: we finally have a nice high-level game engine API, it's possible to make a 3D game really trivially easy, and everything is also very flexible. We also have a lot of new engine documentation (tutorial, classes overview etc.) and useful examples.

The engine reads many 3D model formats, focusing on VRML/X3D standards (so you can make 3D models in pretty much every 3D modeling software), but also supporting Collada and other popular formats. We use OpenGL for graphics, and we have many eye-candy features (shadows, mirrors, bump mapping, screen effects, shaders etc.). The engine is basically integrated into Lazarus (you can drop TCastleContol, and a couple of non-visual components, on the Lazarus form), although it can also be used without LCL (we have our own TCastleWindow). The engine license is modified LGPL (same license as FPC RTL), so you can make both open- and closed-source games with it.

We welcome developers that want to use our engine, and/or contribute of course :) If you want to make a game using our engine, give it a try :)

Pretty impressive. Keep up the good work !!

Hi,

I have tried to compile it under Windows XP with «make all», and got the errors:

I downloaded archive castle_game_engine-4.0.0-src.zip from website:

What's wrong?

A bug slipped into the release, unit castleglwindowsfonts.pas didn't compile. You can either:

1. Comment out the line

   P.Targets.AddUnit('castleglwindowsfonts.pas');

inside fpmake.pp. This unit is not used by anything else, so everything will still compile and work Ok.

2. Or use latest engine 4.0.1 release, where this was corrected :) Download link is from the usual page
http://castle-engine.sourceforge.net/engine.php .

Background: The CastleGLWindowsFonts unit is a little obscure, it was not used by any example program, it's not part of Lazarus packages and it's Windows-specific --- that is why this bug went unnoticed, I didn't test fpmake compilation on Windows. In 4.0.1 this is fixed, and the unit is also tested by one example program, so this bug will not happen again :)
