Simple World 1.0b6 has been released. You can get it in the file releases section of SourceForge.net.
The main change in this version is the addition of the worldlib (World Library), a new SWL library. The worldlib is based in the concept of events management. Events are things that happen (the bug is attacked, blocked, etc) that can provoke the execution of code. For example, when a bug is blocked (event) the bug can try other path (handler).
There are a lot of changes in the stdlib. To be able to add the worldlib new map and multimap data structures were added. In addition the files of the stdlib were splitted in several files: one function, variable or definition in each file. This way, if you don't need all the code of the old header, you can include just what you need.
A new bug, named Coward, was added. The main peculiarities of this bug is that it avoids confrontation and that it's the first bug to use the worldlib.
Finally, to help complex bugs that need a lot of initialization code, for example the bugs that use the worldlib, in every unit of time up to 1024 instructions can be executed.
