hello guys
i need a bycycle or Bike Physic code
is there anybody help me
thanks

There is a car physics example, maybe looking at that would be a good start. It probably wouldn't have any leaning, like a bike would need to work properly. I'm not great with coding, but that's exactly where I would start.

yes, use the car example as a starting point and remove 2 tires. i am not sure though how the handling of a bicycle with spherical tires would be like (it would be fun to test this with a real bike ). for better collision shapes you would have to use a different physics engine.

I've actually tried this, removing two tires does not work properly in balance initially. After modifying the code to only have a 2 wheel setup, the vehicle moves properly, but its balance makes it unable to drive without tipping in a matter of seconds. Maybe add a .roll/.tilt or something in correlation with speed so that the bike can lean without tipping. Just an idea.

But in essence and it's basic idea, you can modify the physics to get 2 wheels - but then you'll just have balancing issues. Hope this helps.

once it rolls fast enough it should be able to keep the balance like a real bicycle. starting could be a bit tricky. i would try to apply a torque which keeps it upright at low speeds or maybe you can simulate the bicyclist's feet somehow.

I have an update on my physics if anyones interested (it's for a motorcycle, similar to a bike). I apply plenty of torque to get it started at first, and once it gets moving it's easy to keep balanced. After created in level and left sit it starts tipping still, no max roll applied. I need to adjust the amount a wheel can turn left or right so turning and going in circles is much more capable.

Ventilator if your interested in the script/demo level let me know if you have ideas on how to get it going well. Thanks.

I'd be interested to see how you got it working. If you're willing to set up a demo level I'd have a big smile on my face if you included an incline to play with the cycle on.

Well I can set up a demo level but it's not perfectly working yet. I'm trying to get the balancing issues implemented myself, however, with my limited time due to college it's sort of difficult.

This code is also for a client, I'll have to make sure I can give out a demo

Balancing shouldn't be too difficult? I had to do it with my newton physics character (haven't even referred to that in ages). The biggest issue was translating the velocities from local to world coords and back.

You need to make invisible 2 wheels
if not you can't make the simulation
that is the secret use 4 wheels but make invisible 2
also the balacing can be simulated with animation
