Physics.SphereCast不会检测已经在半径内的碰撞！！！

加个容错

private bool SphereCast(Vector3 _originPos,Vector3 _targetPos,out RaycastHit hit,LayerMask _layerMask)
{Vector3 dir = (_targetPos - _originPos).normalized;float radius = GetRadius();float distance = Vector3.Distance(_targetPos, _originPos);Vector3 adjustOriginPos = _originPos - dir * radius;if (Physics.SphereCast(adjustOriginPos, radius, dir, out hit, distance, _layerMask)){return true;}else{return false;}
}
