Hello and thanks a lot for getting NC and FC! 🙂
Videos is something that will be shorted out within summer for sure.
Adding a physics force can be done with the Rigidbody.AddForce node similar to c#. Most probably you also need to set the mode to be “Impulse” as well since you want to add the force when a button is pressed (instantly). I just tried this small example bellow and it worked as expected by pushing the object upwards when Fire1 is pressed down.
