Why is this happening?

I am using TweenService to move the model, but the model does not move the player from above. What to do?

Because TweenService doesn’t do physics calculations, so it wont move the player, you can either do it yourself with some math, or use some kind of velocity to move it. I would try to use VectorForce, or LinearVelocity if you want it to move in a straight line.
