Variables变量

• point
  The impact point in world space where the ray hit the collider.
  在世界空间中，射线碰到碰撞器的碰撞点。
• normal
  The normal of the surface the ray hit.
  射线所碰到的表面的法线。
• barycentricCoordinate
  The barycentric coordinate of the triangle we hit.
  所碰到的三角形的重心坐标。
• distance
  The distance from the ray's origin to the impact point.
  从光线的原点到碰撞点的距离。
• triangleIndex
  The index of the triangle that was hit.
  碰到的三角形的索引。
• textureCoord
  The uv texture coordinate at the impact point.
  在碰撞点的UV纹理坐标。
• textureCoord2
  The secondary uv texture coordinate at the impact point.
  碰撞点的第二个UV纹理坐标。
• lightmapCoord
  The uv lightmap coordinate at the impact point.
  所在碰撞点的光照图UV坐标。
• collider
  The Collider that was hit.
  碰到的碰撞器。
• rigidbody
  The Rigidbody of the collider that was hit. If the collider is not attached to a rigidbody then it is null.
  碰到的碰撞器的Rigidbody。如果该碰撞器没有附加刚体那么它为null。
• transform
  The Transform of the rigidbody or collider that was hit.
  碰到的刚体或碰撞器的变换。
