Class Variables类变量

• gravity
  The gravity applied to all rigid bodies in the scene.
  场景中应用到所有刚性物体的重力。
• minPenetrationForPenalty
  The minimum contact penetration value in order to apply a penalty force (default 0.05). Must be positive.
  两个物体接触碰撞时，物体间最小渗透(穿透)深度值。默认0.05.取值范围从0到无穷大。必须是正数。
• bounceThreshold
  Two colliding objects with a relative velocity below this will not bounce (default 2). Must be positive.
  两个碰撞物体的相对速度如果在这个设定值之下，不会反弹。默认值2.。取值范围0到无穷大。必须为正数。
• sleepVelocity
  The default linear velocity, below which objects start going to sleep (default 0.15). Must be positive.
  如果物体的线速度在这个速度设定值之下，物体将进入静止状态。默认0.15。取值范围0到无穷大。必须为正数。
• sleepAngularVelocity
  The default angular velocity, below which objects start sleeping (default 0.14). Must be positive.
  如果物体的角速度在这个速度设定值之下，物体将进入静止状态。默认0.14。 取值范围0到无穷大。必须为正数。
• maxAngularVelocity
  The default maximimum angular velocity permitted for any rigid bodies (default 7). Must be positive.
  物体的最大角速度值。默认是7。必须为正数。
• solverIterationCount
  The default solver iteration count permitted for any rigid bodies (default 7). Must be positive.
  默认的求解迭代次数允许使用任意刚体（默认为7）。必须为正数。

Class Functions类函数

• Raycast
  Casts a ray against all colliders in the scene.
  在场景中投下可与所有碰撞器碰撞的一条光线。
• RaycastAll
  Casts a ray through the scene and returns all hits.
  投射一条光线并返回所有碰撞。
• Linecast
  Returns true if there is any collider intersecting the line between start and end.
  从开始位置到结束位置做一个光线投射，如果与碰撞体交互，返回真。
• OverlapSphere
  Returns an array with all colliders touching or inside the sphere.
  返回球型半径之内（包括半径）的所有碰撞体 collider[]。
• CapsuleCast
  Casts a capsule against all colliders in the scene and returns detailed information on what was hit.
  对场景中的碰撞体进行胶囊的投射，如果相交，返回碰撞体的raycasthit信息。
• SphereCast
  Casts a sphere against all colliders in the scene and returns detailed information on what was hit.
  投射球型物体来判断是否与场景中物体交互，返回 Raycasthit 信息。
• CapsuleCastAll
  Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.
  和Physics.CapsuleCast 不同的是这个函数返回所有交互的碰撞体信息。
• SphereCastAll
  Like Physics.SphereCast, but this function will return all hits the sphere sweep intersects.
  和Physics.SphereCast 不同的是这个函数返回所有交互的碰撞体信息。
• CheckSphere
  Returns true if there are any colliders touching the sphere defined by position and radius in world coordinates
  如果定义的球体和物体发生碰撞，返回真。球体定义在世界坐标系下。
• CheckCapsule
  Returns true if there are any colliders touching the capsule defined by the axis going from start and end and having radius in world coordinates
  如果定义的胶囊和任意碰撞器发生碰撞，返回真。精灵定义在世界坐标系下。
• IgnoreCollision
  Makes the collision detection system ignore all collisions between collider1 and collider2.
  使碰撞体1和碰撞体2的碰撞侦测无效。
• IgnoreLayerCollision
  Makes the collision detection system ignore all collisions between any collider in layer1 and any collider in layer2.
  使碰撞侦测忽略层1和层2之间的所有碰撞器。
• GetIgnoreLayerCollision
  Are collisions between layer1 and layer2 being ignored?
  是否层1和层2之间的碰撞检测被忽略？
