Hey
I would like to write a boat physics.
I have a Unity Essentials book 
I read it.
I am a beginner in Unity3D 
but i a java and c++ programmer.
PS.please, give some example
Help,
Leszek
This is just off the top of my head…
but my first thought about making a floating boat is
Make a boat mesh a rigidbody
Write some function so this rigidbody is self uprighting at a certain rate
Make a cube with a water texture on it
Make it so that when the boat rigidbody interects this cube, it uses addforce to push the boat to the surface of the cube
Perhaps implement some kind of random number, or perlin noise generator and feed the addforce with it’s values, so then the boat will wobble around
How to do all that, I don’t know. But the 2D gameplay tutorial has a spaceship in it that is driven purely by addForces. That might be a place to start
Very interesting topic…
I’m on the answer.
Have you tried to make a little sphere with rigidbody but without mesh renderer under the boat? with the movement script of the ball you can simule the waves…
Hi
I found this - http://forum.unity3d.com/viewtopic.php?t=2356&highlight=sailing+ship
It’s a nice boat physic script.
