shouldn't these be built into the path system. Path is stored in a lnked-list and it would be easier to build there itself. If one has to go at such length to find these things then the new path system is useless for advanced AI.
I think and know that this would be better and easier to implement into the path system.
Please tell me if you are going to implement it, maybe later. Because it is better to have these functionality built into the path system as much better behaviour can be implemented thus.
