High-Level Vehicle Demo

High-Level Vehicle demo project showcases a new High-Level Car Physics System. To learn more on using the system to create your own wheeled vehicle simulation please refer to this article. High-Level Vehicle 演示项目展示了一个新的高级汽车物理系统。要了解有关使用该系统创建自己的轮式车辆模拟的更多信息，请参阅本文.

• Setting engine's power and resistance curves, as well as idle speed (RPM).设置发动机的功率和阻力曲线，以及怠速 (RPM)。
• Gearbox simulation (manual and automatic) enabling you to adjust throttle and speed values for shifting gears along with transition time, as well as to set the number of gears and configure gear ratios.变速箱模拟（手动和自动）使您能够调整换档时的油门和速度值以及转换时间，以及设置档位数量和配置传动比。
• Mathematical wheel model for more realistic steering, enabling simulation of forces affecting the rotating wheel, along with an ability to adjust suspension travel distance, spring, and damping values.用于更逼真转向的数学车轮模型，能够模拟影响旋转车轮的力，以及调整悬架行程距离、弹簧和阻尼值的能力。
• Easy setup of steering and driving axes along with capability to turn the differential lock on and off.转向和驱动轴的轻松设置以及打开和关闭差速锁的能力。
• Switching between different views (driver's view, external camera, etc.).在不同视图（驾驶员视图、外部摄像头等）之间切换。
• Simulation of various surface conditions (such as dry, wet, snow-covered, or icy road, mud, and so on).模拟各种表面条件（如干燥、潮湿、积雪或结冰的道路、泥泞等）。
• A set of debug windows displaying information on all vehicle parameters in real time.一组实时显示所有车辆参数信息的调试窗口。

If you use a wheel device, you might need to readjust the demo settings to control the vehicle properly.如果您使用车轮装置，您可能需要重新调整演示设置以正确控制车辆。

1. Run the demo and press F3 to visualize the axes.运行演示并按 F3 以可视化这些轴。
2. Check the controls status — which axis each control corresponds to.检查控件状态——每个控件对应哪个轴。
3. If the controls mismatch, open the demo project in UnigineEditor to reconfigure them. Find the joystick_input node, it has the car_joystick_input property assigned. Adjust the Joystick Axis parameter where required.如果控件不匹配，在UnigineEditor中打开演示项目以重新配置它们。找到 joystick_input 节点，它分配了 car_joystick_input 属性。在需要的地方调整 Joystick Axis 参数。
