my script worked fine without walking animations but once i implemented them and used isMoving my player does not move forward and if i press down he goes up

ive also made sure that the transitions were correct from idle to walk walk to idle and that the values true , false for ismoving in the transitions are correct but i still dont know what to do
please help

this is for a pokemon style 2d game btw

this is the script i had and what i expect is for the player to move up down left right using the walking animations

void Update()
{
    bool isMoving = false;

    // Determine movement direction based on input
    if (Input.GetKey(KeyCode.D))
    {
        moveDirectionX = 1f;
        moveDirectionY = 0f;
        isMoving = true;
        animator.SetBool("isMoving", isMoving);
    }
    else if (Input.GetKey(KeyCode.A))
    {
        moveDirectionX = -1f;
        moveDirectionY = 0f;
        isMoving = true;
        animator.SetBool("isMoving", isMoving);

    }
    else if (Input.GetKey(KeyCode.W))
    {
        moveDirectionX = 0f;
        moveDirectionY = 1f;
        isMoving = true;
        animator.SetBool("isMoving", isMoving);

    }
    else if (Input.GetKey(KeyCode.S))
    {
        moveDirectionX = 0f;
        moveDirectionY = -1f;
        isMoving = true;
        animator.SetBool("isMoving", isMoving);

    }

    // Move the player based on the determined direction
    if (isMoving)
    {
        Vector3 moveDirection = new Vector3(moveDirectionX, moveDirectionY, 0f).normalized;
        transform.Translate(moveDirection * speed * Time.deltaTime);
    }

    // Update animator parameters based on current movement status
    animator.SetFloat("MoveX", moveDirectionX);
    animator.SetFloat("MoveY", moveDirectionY);
    animator.SetBool("isMoving", isMoving);

}

}
