Cannonball fly direction / physic ?!

  • oke i watched an Video on Youtube where someone shot an cannonball to an enemy ship and the Fly direction looks weird. This cannonball miss the ship

    timeline is 8:19

    (u can scale video speed down on youtube)

    in my opinion the cannonball should hit the rear part of the ship buuuut its hits the water here

    there is something wrong.

  • I think that was the cannon next to him. Speed, wind, and ship direction all play a role in where the cannonball is going to land.

  • @the-bobcat-316 there are only 2 cannonballs and both are going wrong.

  • If you jump out of a moving car do you keep travelling forward or instantly stop when you're outside? That's how the cannonball feels when being shot out of a ship moving forward :P

  • @naamar1 dude we talking about CANNONs not throwing an softball u cant campare it with an jump from an car.

  • @kailmenoke It's fine actually...their galleon is going wicked fast and the other ship is also at a good clip.

    Nothing wrong there, his crew's shots hit fine as well.

  • There is nothing wrong there. They failed to aim correctly. Their ship is going forward fairly fast as is the other ship. They fired at where the ship was not where it was going to be. That coupled with their moment of going forward means they missed. The cannonball flew exactly where it was aimed.

    That is the key to landing cannon shots. Otherwise they'll always hit water.

  • @kailmenoke Laws of physics don't care if you're a cannonball or a softball :P

  • I always felt that you had to lead your cannon shots TOO MUCH when at full sail. But I suppose it's one of the things you just have to get used to. They fired a lot higher than I thought they should, too. So I'll have to adjust. I'm sure it'll be fine once everyone gets the hang of it, although as a 'soft skills' game, I do wonder if some of the cannon mechanics might be a little confusing for some people who are used to 'lining up a shot' in 'shooting scenarios'.

  • @kailmenoke Cannonballs, cars, the physics are the same even if the magnitudes are different.

    In talking about softballs and cannonballs, the physics of their trajectories are identical. You apply an initial force and they follow a parabolic trajectory assuming a gravitational field. When you are launching from a stationary position, you only need to consider force components in two directions, one vertical and the other horizontal.

    Now when you start moving, then things become more complicated. Now you have to consider motion in the x-z plane in addition to your parabola. Neat stuff in my opinion.

    But I'll have to test this vigorously when I play next. Based on physics, velocity in the x-z plane of motion is essentially constant. That means that if you are traveling at constant speed and fire the cannon and you are shooting perpendicular from the side of the vessel, the cannonball shouldn't move at all to the left or the right of the cannon. It should only appear to go up and then back down again.

    I guess it is time to pick at the physics engine here...

  • Cannonballs just acts a bit weird like that sometimes with lag
