Yep, I've been trying for days and can't find a way to get acceptable results.
NX_BF_KINEMATIC doesnt seem to work at all.
PH_CHAR provides acceptable movement BUT is very indifferent to its surrounding - walking up very steep ramps, pushing all objects aside disregarding their mass.
Using PH_BOX solves the problems PH_CHAR had; by disabling gravity for the player entity and using a custom gravity function I can also eliminate the problem of the player sliding around all the time - but this results in jerky movement.

So... anyone has any experience with this?
