You were saying in your github that you needed help with force fields. What do you need to know about that?
I googled the vector field and I learnt that it's a kind of particle system. This should be correct because all PVFs are in the particles package. Whatever, it's beyond my knowledge.
Anyway, it's not a high priority task. There are only two PVFs in the game assets, and they even don't have regular names. Seems that even Taleworlds doesn't take it seriously.
