Boat steering physics.

Unity Engine
1

Hello ladies and gents,
Have a quick question, just wondering if anyone has any ideas for some good solid boat steering, I used the old vehicle example with the buoyancy that was posted by andeee and I am trying to make my boat steer without flipping over at high speeds plus stop it from rotating in a continuous circle at low speeds now I am using the free version of unity so any thoughts?

Fake it. Don’t use real buoyancy. Just apply a sine wave function for the ‘floating’ effect and move your boat with standard techniques. Pretty sure that’s what games such as Hydro Thunder are doing.

Kewl I never thought of that, I mean I was trying to go for realism and my boat just seemed to slide on ice and I was like wow that is funky but I am going to try that.

Thanks

Realism is impossible in a game. Games are all about shortcuts and voodoo tricks to present an illusion.

Besides, have you ever tried keeping a real boat pointed at the next set of nav lights or a compass heading on a river? Not exactly what I would call fun, more like work!

Hey Quietus,
Did you get my message hopefull you did, but if not that is cool. This is for the forum also, just need a little assitance on this boat script.
Been going over this thing for a while and wonder if anyone could take a look at this let me know what is wrong with this script, my steering is just not working in the water but it would work when in mid air, go figure.

	//checking to see if input is called.
		if(stickInput)
		{
			move = Input.GetAxis("Vertical");
			steer = Input.GetAxis("Horizontal") * turnSpeed ;
		}
			
		//add force the rigidbody for moving and turning
		rigidbody.AddRelativeForce(forwardDirection * move * engineForce * Time.deltaTime);
		rigidbody.AddRelativeTorque(turning * steer * Time.deltaTime);

Hey,

This is beast, so basically when you are doing the turning is suppose to do a spin and depending on how you press the turn key it would spin or just turn slightly.

Message? No sorry I didn’t. Since they upgraded the forums it horribly broke notifications. But it looks like you got what you needed. Good luck!

I will shoot you a message again I would like to show you something or have you take a look at something. If you don’t mind.
