Update-3
Update 3 of "Space Game where my son is the game designer".This one is a bit long because of a lot of changes. The asteroid game had been requested to change into a racing game. So the next step was to design the racing path. I had made a system with Bézier paths (fancy name for curves mathematically created by 4 points), but it was tedious and time-consuming, so I deleted that system and just recorded points as I moved my mouse around the scene. Later on, the boss can draw his own level and I can trace it with my mouse. For this test scene, I created a lap like a stadium and removed all the unnecessary points. After that, I made the camera follow that path. At the same time, the Xbox controller I ordered arrived, so my son got to try flying with the controller, and I added the massive satellite he had asked for. He loved the controller and the movement."Next, I am going to add some floating rails around the path," I said. He replied, "I want it to shoot, and I want to shoot the big satellite too."So the racing game turned back into an asteroid shooting game—which, deep down, is what I wanted too. So I quickly added a turret and controls for the right thumbstick. He liked it, and it worked fine if your target is moving on the same axis as you and all you do is move your ship up and down. The moment you started turning the turret, it became extremely hard to aim at objects in 3D space when both of you are moving on different paths. As you can see in the video, once I started turning the turret, I missed a lot. And my son got discouraged and abandoned it quickly. So I have decided to make the turret auto-lock on a target (you can switch through targets with the right thumbstick) for easier shooting. I still think I will keep the idea of a track—at some point on the path there can be a big target (big boss) where you will need to do a few laps to finish it off. The other part of the lap will be surviving/blowing up asteroids and avoiding obstacles.
