Setting a body to move in a river?

I’m working on a map for my mod and I wanted to have a sequence where the player comes upon a body washing down an aqueduct. However, my original plan (to parent the body to a func_tracktrain) is impossible since prop_ragdoll cannot be parented. Is there a way to move a physics object on a very specific path without affecting the player? Thanks for any insight! <3

Try using a trigger_push either with the flags set to exclude players (or, if you really want only the body to move, a link to a filter entity).
