A question on wheel physics

26.7k ToeTips  one year ago

Like how do they work to move something? Is it like a force acting in the very middle of the wheel pushing it forward or is it like real life where the action of rolling pushes them forward?

Also if I were to put a thruster in on a car as the main engine would that handle the same as regular engine connected wheels?

This method has the potential to be a differential of sorts since none of the wheels are 'driving'.

    Thank you so much for help, not just now but every time you've taken the time to answer.

    @ToeTips the small turbojet engines make basically no sound at low inputs. You can run it at low input and increase the thrust multiplier as needed
    An open diff doesn't apply any torque, while a limited slip diff applies torque to balance the speeds of both wheels on an axle. This torque is just added to the engine torque.

    Okay well unless there was a way to silence engines I would do that but I'm trying to make an electric car so I would probably need to use some kinda glitch. Is there another way to get the moving without using the piston and airbrake thing? Preferably at 200mph? Also is the diff just a matter of adding roll or yaw to the code?

    (🤓 answer) technically the engine and brake spins the wheel, then the game determines the slip and applies forces on the plane using the slip
    Differentials can be made completely in FT but you need one engine for each wheel

    @ToeTips Yeah you could do it with FT, and no you can't silence engines :/

    @jamesPLANESii And the traction curve is needed to make the car feel natural. Could it be done with ft? Also is there a way to silence engines?

    @Dragoranos Okay thanks!

    1. Yeah all traction acts as a force in the very middle of the wheel. Lame imo...
    2. Sorta, but it won't have a traction curve or anything so not quite

    Most games seen to magically push the car forward to avoid having to make collisions (often buggy and not accurate)

    So I think it's like that in SP too

    About the engine/thruster thing: It does very similarly. It does actually have better grip sometimes, as the wheels have a much lower chance to slip that way.
    But a well done car would probably be better anyways.

    Cars are strange in this game. Very strange. The way grip works is just so different from real life.

    Thats all theory thought, I dont know how the coding for wheels work in this game
