Gravity dramatically changing when adding player controls

Question

so if when I add my rigidbody2D the gravity works as it normally would. my player sprite falls down and it's velocity downwards increases. Once I add some very simple player controls it seems to almost be throttled? bumping up the gravity to something like 50 still doesn't feel the same as gravity=1 (default settings) without my player control script. here's my code.

public class playerControlls : MonoBehaviour {

public float maxSpeed;

void Update(){
    float moveH = Input.GetAxis ("Horizontal");
    Vector3 movement = new Vector3 (moveH, 0.0f, 0.0f);
    rigidbody2D.velocity = movement * maxSpeed;
}
}

Answer 1

You are setting you sprites velocity to be limited by maxSpeed, this includes its falling speed.

rigidbody2D.velocity = movement * maxSpeed;

Means the sprite will never achieve downwards speeds that exceed maxSpeed. When setting the movement vector, include rigidbody.velocity.y.

void Update() {
    float moveH = Input.GetAxis ("Horizontal");
    Vector3 movement = new Vector3 (moveH, 0.0f, 0.0f);
    movement *= maxSpeed;
    movement.y = rigidbody2D.velocity.y; //movement vector now maintains current falling speed
    rigidbody2D.velocity = movement;
}
