How to make 2D Movement with only 1 Axis at the same Time,How to make 2d Movement on 1 Axes at the same time?

I want that my Player can only walk on 1 Axis at the time. It should depend on wich button was pressed first if both axis are called

It doesnt seem to work like i want to heres my code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayerMovement : MonoBehaviour {

 public float movementSpeed;
 public Rigidbody2D rb;
 private float moveX;
 private float moveY;

 private Vector2 moveDirection;

 void Awake() {
     float moveX = Input.GetAxisRaw("Horizontal");
     float moveY = Input.GetAxisRaw("Vertical");
 }
 
 
 void Update()
 {
     InputCalculation();
 }



 void InputCalculation() {

      moveX = Input.GetAxisRaw("Horizontal");
      moveY = Input.GetAxisRaw("Vertical");

     moveDirection = new Vector2(moveX,moveY);
 }

 private void FixedUpdate() {

     if ( moveX != 0.0f || moveY != 0.0f ) // if player asked to move

{

 // if the pressure is more important on the horizontal axis
 if ( Mathf.Abs(moveX) >= Mathf.Abs(moveY) ) // if both values are equals the default behaviour will be to chose horizontal axis.

 {
     MoveX();
 }
 else
 {
     MoveY();
 }

}

 }

 void MoveX() {

     rb.velocity = new Vector2(moveDirection.x * movementSpeed, 0);

 }

 void MoveY() {
     rb.velocity = new Vector2(0, moveDirection.y * movementSpeed);
 }

} ,

I would prefer it, to stay with a rigidbody movement

OK: Ive found a solution, wich is probably not the best but its ok. Now, i check if i am currently moving in an axis each frame, Problem: The if-statement i am checking first, is priority, means: if i am moving on the x achsis and then i want to move on the y, it will change my direction of movement. But if i am moving on the y, and then want to move on the x, my movement on the y will stay until i led my fingers from the y.

If anyone has a better Solution, pls help me`using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Player$$anonymous$$ovement : $$anonymous$$onoBehaviour {

 public float movementSpeed;
 public Rigidbody2D rb;
 private float moveX;
 private float moveY;
 private bool can$$anonymous$$oveOnY = true;
 private bool can$$anonymous$$oveOnX = true;

 private Vector2 moveDirection;

 
 
 
 void Update()
 {
     InputCalculation();
 }



 void InputCalculation() {

      moveX = Input.GetAxisRaw("Horizontal");
      moveY = Input.GetAxisRaw("Vertical");

     moveDirection = new Vector2(moveX,moveY);
 }

 private void FixedUpdate() {

     if (moveDirection.y >= 1 && can$$anonymous$$oveOnY || moveDirection.y <= -1 && can$$anonymous$$oveOnY) {
    can$$anonymous$$oveOnX = false;
    $$anonymous$$oveY();

}

if (moveDirection.x >= 1 && can$$anonymous$$oveOnX || moveDirection.x <= -1 && can$$anonymous$$oveOnX) { can$$anonymous$$oveOnY = false; $$anonymous$$oveX();

}

 }

 void $$anonymous$$oveX() {

     rb.velocity = new Vector2(moveDirection.x * movementSpeed, 0);

 }

 void $$anonymous$$oveY() {
     rb.velocity = new Vector2(0, moveDirection.y * movementSpeed);
 }


 private void LateUpdate() {
     if (!can$$anonymous$$oveOnX)
     {
         can$$anonymous$$oveOnX = true;
     }

     if (!can$$anonymous$$oveOnY)
     {
         can$$anonymous$$oveOnY = true;
     }

     rb.velocity = new Vector2(0,0);
 }

} `
