Trying to make a Rigidbody2d variable in unity for a flappy bird sort of game

Question

my code is

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

public class JumpScript: MonoBehaviour
{
    // Start is called before the first frame update
    IEnumerator Wait(){
        yield return new WaitForSeconds (1);
    }
    void Start()
    {}
    public RigidBody rb;
    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey("w")){
            StartCoroutine(Wait());

        }
    }
}

my errors are Assets/JumpScript.cs(13,12): error CS0246: The type or namespace name 'RigidBody' could not be found (are you missing a using directive or an assembly reference?)

I'm trying to make a flappy bird sort of game as practice for unity + c#

Answer 1

You have capitalized "RigidBody" incorrectly, it should be "Rigidbody". Also, if you are working with 2D then you should be using "Rigidbody2D". Also, I am not 100% sure what your question here is, I assume you want help to just fix that error, so there you go, change public RigidBody rb; to public Rigidbody2D rb; (if you are making a 2D game you should be using Rigidbody2D).

Answer 2

it is Rigidbody not RigidBody you spell it incorrectly

if you are working with a 2D game you should use Rigidbody2D not Rigidbody

and for 3D game, you must use Rigidbody

make sure you have imported using UnityEngine;

change public RigidBody rb; to public Rigidbody rb;
