Question by Charmatataa · Dec 19, 2018 at 09:57 AM · movement2d-platformerphysics2dmovement script

Velocity is not matching the Vector3 it is assigned

Hello, everyone! I've had this problem with a 2D object (the player) that is supposed to move left and right. Every time I move it over a long distance, I can't help but notice the object jiggle every so and often. After looking further into my code, I've discovered that the "movement" Vector is not matching the Velocity:

 float horizontal = Input.GetAxis("Horizontal");
 
 Vector3 movement = new Vector3(horizontal * speed, rb.velocity.y, 0f);
 
 rb.velocity = movement;

The "movement" vector is (7, 0, 0) while the velocity vector varies between (5, 0, 0) and (6.7, 0, 0) at maximum.

What am I doing wrong? Is this the cause of the "jiggling"? I appreciate all the answers!

The decreased velocity vector is probably due to drag. To fix the jittery movement, try setting the Rigidbody's interpolation mode to interpolation.

By drag do you mean linear drag?
