New Spine Runtime: Castle Game Engine

michals

Castle Game Engine http://castle-engine.sourceforge.net/engine.php is a cross-platform (Windows, Linux, MacOSX, Android, iOS...) open-source 3D/2D engine. It is developed for FPC/Lazarus using a modern Object Pascal language.

We have just released a new version 5.1.1 of the engine that officially adds support for Spine 2D animations in our engine 🙂 The full release annoucement is on http://castle-engine.sourceforge.net/news.php?id=2014-12-30 , and a lot of information specific to Spine and 2D is on https://sourceforge.net/p/castle-engine/wiki/Spine/ . It lists supported Spine features, and shows developers how to use Spine animations to make beauiful 2D games 🙂

If you think it's cool, you could also add our engine to the runtimes listed on http://esotericsoftware.com/spine-runtimes . Our language is Pascal 🙂

We have also released a small demo showing Castle Game Engine + Spine on Google Play ( https://play.google.com/store/apps/details?id=net.sourceforge.castleengine.castlespine ) for Android, and on https://sourceforge.net/projects/castle-engine/files/castle_spine/ for Windows / Linux. The full source code of the demo is available in Castle Game Engine examples of course 🙂

Also a new game using Castle Game Engine + Spine is already in the making: Venice - a great 2D adventure game with superb graphics and storyline, see https://www.facebook.com/Venicethegame !

Many screenshots from Spine working (most of them showing Spine animations in our 3D/2D model browser view3dscene, http://castle-engine.sourceforge.net/view3dscene.php ) are on our Google+ and Facebook pages ( https://plus.google.com/b/101185352355602218697/101185352355602218697/posts , https://www.facebook.com/castleengine ).

Have fun! 🙂

In the Goblin lady picture, it seems to me that you are blending incorrectly the alpha channel, so the seams look dark.

It could be because of the blend-mode and/or the pre-multiplied alpha in the images.

No, as far as I see it's simply because goblins-ffd (in SpineTrial/examples/goblins/export/goblins-ffd.json ) was exported without "bleed" option at texture atlas creation. So there are black colors around the (partially) transparent edges of the parts, and therefore it's normal that the edges are getting darker... Fixing the atlas texture makes the seams disappear. Our own test models, exported always with "bleed", also look perfect.

In Castle Game Engine we use standard blending mode (although it can be adjusted in our engine, for any shape, see http://castle-engine.sourceforge.net/x3d_extensions.php#section_ext_blending ), this also implies that by default we assume that alpha is not pre-multiplied.
