JavaScript => public function GetGroundHit(out hit: WheelHit): bool;
C# => public bool GetGroundHit(out WheelHit hit);

Description 描述

Gets ground collision data for the wheel.

获取车轮的地面碰撞数据。

If the wheel collides with something, returns true and fills the hit structure. If the wheel is not colliding, returns false and leaves hit structure unchanged.

如果车轮碰撞到什么，返回true；如果车轮没有碰撞东西返回false，并且保持碰撞结构不变。

The reported hit is always the closest one. Because the tire friction model does not automatically respond to other PhysicMaterials, any simulation of different ground materials must be done manually by adjusting forwardFriction and sidewaysFriction based on collider's material returned here.
