Game crashes on input

[3nderall]

I just started developing in stride with only basic unity knowledge. I managed to get my character jumping (I'm making a flappy bird clone) and when I press space a cmd window opens and then the game window and the cmd window closes. Why is this happening?
Here is my script:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Stride.Core.Mathematics;
using Stride.Input;
using Stride.Engine;
using BulletSharp;

namespace flappyBord
{
    public class birdScript : SyncScript
    {
        public float jumpPower;
        public RigidBody rigidBody;

        public override void Start()
        {
            
        }

        public override void Update()
        {
            

            if (Input.IsKeyDown(Keys.Space))
            {
                rigidBody.LinearVelocity = new Vector3(0, jumpPower, 0);
            }
        }
    }
}

I can see my character jumping before the game crashes

if you press the run button in VS 2022 it should also give you a better error.

You may also prefer Input.IsKeyPressed instead of Input.IsKeyDown here as that will only trigger once per button press.

I ran it in VS and the problem is the rigidBody variable isn't populated but I can't figure out how to populate it. In unity, you can just drag the rigid body module into the empty field.

can you try public RigidBody rigidBody{ get; set; }; instead of public RigidBody rigidBody; and then assign it in editor?

If the Rigidbody is attached to the Entity you can also use Entity.Get() to find the component in the same entity and assign it at Start().

I just came off of my computer but I'll try this tomorrow.

That still doesn't work

That's the wrong Rigidbody type, you're using bullet's. Remove your using BulletSharp; and change public RigidBody rigidBody; to public RigidBodyComponent rigidBody instead

Thanks for the solution, the the body in RigidBodyComponent is a lowercase b instead though.
