    I make a controller on a rigid body and stopped at the next moment, the object jumps in place constantly, here is an example

    Code (CSharp):
    2. if(!Ground){ MoveDir.y += -1f; }else{ MoveDir.y = 0f; }
    3. if(MoveDir !={ // MoveDir is Vector3 x, z axis vertical and horizontal
    4.     RB.MovePosition(RB.transform.position + MoveDir * 4f * Time.fixedDeltaTime);
    5.     }
    that is, as planned, it should go down if there is no ground under its feet, while the ground is checked by a sphere under the collider (0.2 lower).

    I don't understand why he jumps in place...
