Thanks so much! I didn't think people would find this so quickly.
- Good point, I will setup teleport and add back tunneling when smooth sliding.
- I have uploaded a youtube video explaining the simulation and steps to fire the cannon.
- Yes I wanted to be able to shoot at a moving target, so I added the button which spawns the soldier, it was more for personal use so out of context I can see why its confusing. I'll add some more logic there to either remove it or cause him to despawn.
