All in all there is not a great deal you can do I dont think about gettting a decent ally system going until, if and when Lee does something to change the current situation and either fixes the current AI drain and perhaps adds a level of further support for allies in an update. Two slightly differing influences which each in their own way for various reasons, one or the other is a prerequisite for decent AI in my humble opinion.
There are a number of users that have worked on a producing a level of AI and or allies though I have not checked them out myself.
The little work I did on creating allies remains on the shelf with FPSC awaiting some future update which would make picking it up again and possibly developing further worthwhile.
Currently I am not sure when that might be if ever as the schedule for any such update is as far as I am aware now in something of a state of uncertainty.
A long wait is a certain it seems. Personally I see no point in my own continuing with any AI/ally work as FPSC is unusable for me in its current condition.
There have been a lot of posts about allies and AI - scattered about now I guess - so no idea how helpful a search would be.
I dont like control of Allies or other Characters either in game but would prefer a level of self thinking as it were in intelligent behaviours. That however is difficult to achieve in FPSC and not worth the massive amount of effort for me currently. Not sure if it ever will be worth the effort but I would look at it again some time perhaps if an update allows.
There have been mentions of integration of some features perhaps to provide for Better AI and perhaps allies but until it happens its not a reality so you cant bank on that either.
I am sure that if it does not happen officially there will always be some users who will continue their work or attempt to achieve these things again in the future and hopefully will be well successful.
Lets hope so.
