Joystick Demo: radius of turning circle is very big

[Former user]

I tried the joystick demo to control the car, but it‘s hard to turn. It takes a long way to turn 180 degrees.

Is there any params to set turning radius? Anyone know how to make it easy to turn?

When using the joystick demo to control the vehicle, you can use the steering modifier buttons (located above the joysticks) to adjust the steering sensitivity. For a tighter turn radius, hold down the right steering multiplier while steering with the joystick and you should be able to achieve your intended result.
