I tried the method down below, and while the T Cell moves perfectly fine with it, upon reaching a wall it ignores it and continues moving.
I also tried printing the transform as it moved via the old function, and it seems like upon interacting with a staticmesh, the transform is set back to the prior coordinate, at which point it ceases moving. I am tempted to go down the non-physics route you suggested however, as I intend on creating this program without any physics modules in play.
