Two videos of a bowling game I'm screwing around with. It's the same swing mechanics as the golf game I originally started - there's no way I'm designing golf courses right now.
What I'm going for here is something I have never seen in a bowling game, but is often claimed - realistic pin physics, and realistic ball spinning.
Even the PBA's own game on the iPhone has crappy physics, and you can steer the ball down the lane. I want to see pins chaotically "exploding" when hit hard in the pocket. I want them bouncing off the wall for a possible (yet rare) split conversion.
Anyways, still working on all the above, but here's where I am so far....
!!In my game, you set the spin with the backswing, the direction with the forward. Nothing original I'm sure. I left the mouse cursor visible for the video. There are also two additional views in the video so you can check out the ball action.
I designed a bowling game back in 2009, but I abandoned it so I could make Daredevil Dave - a good choice.
But the bowling game was good and I'm wanting to design a trackball game, so I'm picking up where I left off, but starting from scratch too

Some of the old graphics are in this test game.
You start off poor, playing in a backyard bowling league on a crappy homemade alley (see second video). You work your way through various locations, including the middle of a downtown street, an underground Mafia hideout/bowling alley (it could happen!), and some others.
Even back then on the old iPhone 3g I had realistic pins. I don't even care for bowling all that much, but someone has to!!!
The pins are exact dimensions, down the the hundredth of an inch - or close. The ball is the same, with the weights of each being what they should be.
The bowling alley is regulation size. The lanes are oiled and the ball will gain more traction toward the end. That's why the pros get that nasty hook in their shots right at the end. I have never seen a game simulate that hook - mine does. I think.

The curved path of the ball is actually caused by the amount it is spinning. In other words, the physics engine in the game is causing the curve - I didn't program the curve in so it "looks real". The spinning of the ball actually determines the amount of curve. A lot of games are designed to look "real" - like the ball is spinning but it's just for looks. In this game, if the ball spins the ball will curve that much. If you want a straight shot, don't spin it!
Any bowlers here? I'm open to all suggestions, and will gladly send out test versions to anyone who wants one. I'm not ready for that but I could be in a day or so if people are interested. It plays great with a mouse or arcade trackball.
I also suspect there is another sub-forum for this game discussion, so I will check that out.
