车轮的接触信息,由 WheelCollider 报告。
WheelCollider 的摩擦力是使用基于打滑的轮胎摩擦模型独立于
物理引擎的其余部分计算的。这样可以实现更逼真的行为,
但会导致车轮碰撞体忽略标准 PhysicMaterial 设置。
模拟不同地面材质的方法是查询 WheelCollider 以获取其碰撞
信息(请参阅 WheelCollider.GetGroundHit)。通常,您获取车轮所碰撞的其他
碰撞体,根据地面的物理材质修改车轮的 WheelCollider.forwardFriction 和
WheelCollider.sidewaysFriction。
WheelHit 结构的其他成员通常用于信息查询目的或特殊
效果。例如,如果 forwardSlip 或 sidewaysSlip 超出一定的阈值,可以播放
“轮胎打滑”声音。
另请参阅:WheelCollider.GetGroundHit。
collider | 车轮所撞击的其他 Collider。 |
force | 施加到接触面的力的大小。 |
forwardDir | 车轮所指向的方向。 |
forwardSlip | 滚动方向的轮胎打滑。加速打滑为负数,制动打滑为正数。 |
normal | 接触点处的法线。 |
point | 车轮与地面之间的接触点。 |
sidewaysDir | 车轮的侧向方向。 |
sidewaysSlip | 侧向方向的轮胎打滑。 |
