Is there a way to make this a shorter phrase.

if(cheeseburger){jump}

using System.Linq.Expressions;
using Unity.VisualScripting;
using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.UI;
public class Playerjump : MonoBehaviour
{
    [SerializeField] private float _velocity = 1.5f;
    private Rigidbody2D _rb;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        _rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        if (Mouse.current.leftButton.wasPressedThisFrame)
        {
            _rb.linearVelocity = Vector2.up * _velocity;
        }

        if (Keyboard.current.spaceKey.wasPressedThisFrame)
        {
            _rb.linearVelocity = Vector2.up * _velocity;
        }
    }
}
