Hello CrystalSpace,
Well I'm back, had a great conference and have dived into implementing the stack-based behaviour tree I discussed here before leaving.

One design change I found necessary was to add another status, BT_NOT_STARTED, to use in resetting and initialising nodes.

Revision 4907 switches from the previous 2009 method of parsing the entire tree every frame to passing a single node every frame. This will make the method far more scalable and should help with debugging as progress can now be tracked in the behaviour tree's stack. This is a significant revision that is key to this part of the project. If there are any comments in particular on this revision I am very keen to hear them.

In a smaller commit, revision 4906 merged all changes from whilst I was away and since I began coding. I intend to complete these merges at least once a fortnight to make the eventual process of merging my branch to trunk far simpler.

That's all for this week, next week I intend to add more to the debugging tools by making better use of the status BT_UNEXPECTED_ERROR and starting to look into loading from XML and making a dedicated propclass for the behaviour tree. Any suggestions either here, by email/mailing list/irc are always appreciated.

Kind regards,
Sam.
