PureBasic 4.60 bêta 1 est disponible, cette version est principalement axée sur la 3D, mais pas seulement.

Citation:

Hello everybody!

You probably saw the fake April 1 announcement, but as we all know: real releases happen on a Monday! :P So here it is, after a longer than usual period: The first beta of the upcoming PureBasic 4.60 release. It is available for download on your personal account.

This release is mostly about the 3D side of things, but there are new features for application programmers as well. The OGRE engine was updated to version 1.7.0 and we switched the physics engine from ODE to Bullet. Furthermore, there are a ton of new 3D libraries and commands. You can see the full list below. The 3D commands are not documented yet, but we will put up some examples to demonstrate them.

A special thanks to G-Rom and TMyke from the french forum for their help on the new 3D commands!

Note: It may be required that you update your DirectX 9 runtimes to work with this new version. If you get a missing DLL error when running the 3D examples, then install this: http://www.microsoft.com/downloads/

On the application side of things, the most notable addition is the CanvasGadget() command. It is a simple drawing surface that provides detailed mouse and keyboard events to easily implement custom data views or controls (all cross-platform of course). You can see this new gadget in action in the IDE already: The new file panel and the new color picker tool both make use of it. Other than that, there are some smaller new commands like additions to the LinkedList library for example. All new non-3D commands are already documented in the manual.

The IDE got some additions as well, like the ability to build projects directly from the command-line, or the option to be warned when a file is changed on disk while open in the IDE. Unfortunately, the automation framework that I talked about here on the forum did not make it into this release. It wasn't finished in time, and its not a big enough priority to justify delaying this release any longer.

Finally, we are in the process of changing the PureBasic documentation to be more precise and readable when it comes to function parameters and return values. This is still a work in progress which should be finished for the final release. Comments on the new structure are welcome.

Traduction exprès de djes, merci à lui

Citation:

Petite traduction rapide : cette sortie est principalement orientée 3D, avec la mise à jour d'Ogre en version 1.7.0, et le moteur physique d'ODE vers Bullet. En plus de cela, des tonnes de nouvelles bibliothèques et commandes 3D. Les commandes ne sont pas encore traduites, mais il y aura des exemples.

Un merci spécial à G-Rom et Tmyke pour leur aide sur les nouvelles commandes 3D!

Note: il peut être nécessaire de faire une mise à jour de DirectX. En cas de problème de DLL, il faut aller là : http://www.microsoft.com/downloads

Du côté application, la principale mise à jour est la commande CanvasGadget(). C'est une simple surface de dessin qui fournit des événements souris et clavier détaillés pour facilement implémenter des vues de données personnalisées ou des contrôles (le tout multiplateformes) (NdT : par ex une surface de dessin comme dans Paint). Vous pouvez déjà voir ce gadget dans l'IDE : le nouveau panneau de requête de fichiers et le nouveau sélectionneur de couleurs l'utilisent. A part ça, il y a quelques autres nouvelles petites commandes comme des ajouts à la bibliothèque Linkedlist (listes chaînées). Toutes ces nouvelles commandes sont déjà documentées dans le manuel.

L'IDE a été amélioré, possibilité de construire des projets à partir de la ligne de commande, ou l'option d'être averti quand un fichier a été changé sur le disque. Malheureusement, le framework automation ne sera pas finalisé dans cette release, il n'était pas fini à temps et pas assez prioritaire pour retarder encore la sortie.

Enfin, la documentation sera bientôt plus précise et lisible quand il s'agira des paramètres de fonctions et des valeurs de retour. C'est un travail en cours qui devrait être terminé pour la sortie finale. Des commentaires sur les nouvelles structures sont bienvenus.

Très sympa cette nouvelle version, avec les nombreux ajouts 3D.

On voit bien la puissance du moteur ogre, même avec de simples scènes, c'est classe :D !
A ce propos, la version d'ogre utilisée est la 1.7.0 avec purebasic 4.60, donc c'est aussi une bonne chose.
