Hi folks, I followed the script word for word and it appears that my rockets (even though aren’t rotated anywhere in the Inspector) are appearing vertical as per screenshot.
Found the solution, not sure if it’s a glitch or not but I highlighted the Rocket node’s Rotation and saw the code for that is rotation_degrees. So I added another line in the rocket.gd under the _physics_process(delta) function with
rotation_degrees = 270
Mileage may vary? I don’t know, I am using 4.0.2 so I’ve no idea if that’s a glitch or not.
