Solarus 1.0.0

Release date: 2013/05/03

The "I love Lua" release.

This is a major release. The version number switches from 0.x to 1.x because there is a brand new Lua scripting API. I now consider that Solarus can be used to create your own Zelda-like games in decent conditions. By "in decent conditions", I essentially mean: with a clean and stable scripting API. Clean because there are nice datatypes now and the API is much easier to use, less error-prone and more with the Lua spirit. Stable because future versions of the scripting API will now try to keep compatibility with existing scripts. Any API change that breaks compatibility will now be clearly documented.

Data files and scripts written for solarus 0.x are not compatible with solarus 1.x. Which is not a problem since until now, I never said you could create a quest in decent conditions :) More seriously, I guess I'm the only one to have a lot of data files and scripts created for solarus 0.x. Anyway, conversion scripts are provided to upgrade your existing data files, but not your scripts (the scripting API, which was working but ugly and unstable, has totally changed).

Engine changes

• Rewrite the Lua scripting API from scratch. Cleaner, real datatypes, much easier to use, less error-prone, much more features, fully documentated.
• All scripts now live in a single Lua world.
• Add support of scripted graphics.
