Physics.OverlapSphere 相交球

static function OverlapSphere (position : Vector3, radius : float, layerMask : int = kAllLayers) : Collider[]

Description描述

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[]。

NOTE: Currently this only checks against the bounding volumes of the colliders not against the actual colliders.

注意：一般来说，这个函数检查的是碰撞体的包围体，而不是碰撞体的实际边界。
