nav_crowd_add_fixed adds a walker with no steering, and nav_crowd_place puts it (snapped to the mesh) where the player is, with the velocity they have, each frame. The others plan round it by that velocity, and whatever it was pushed by is undone at the next placement. crowd_test: six walkers aimed through a standing player come no closer than 1.71 m and all get past, and the player stays where it was put. nav 16/16 on the Mac and the PC; DLL KERNEL32 only.
