Diablo III was just released, so that threw a spanner in the works for a few days. However, after many iterations, the Party Attack system is ready to upload.
I've done a lot of restructuring, and still more to do. Been trying to decide if I like C# properties - they seem to be a source of much code inconsistency and Unity abuses them quite a bit by hiding expensive operations as properties.
I've had to do quite a few iterations of the party system, trying to get the structure right. I wanted to make the party system very flexible so you could have parties of 1 to 9 characters, and even support enemies dynamically joining up to form parties.
