示例1: test_collision_with_ground
/**
* \brief Tests whether a point collides with the ground of the map.
*
* The ground is the terrain of the point. It is defined by the tiles and
* by the presence of entities that may change it
* (like dynamic tiles and destructible items).
*
* This method also returns true if the point is outside the map.
*
* \param layer Layer of the point.
* \param x X of the point in pixels.
* \param y Y of the point in pixels.
* \param entity_to_check The entity to check (used to decide what grounds are
* considered as obstacle).
* \param [out] found_diagonal_wall \c true if the ground under this point was
* a diagonal wall, unchanged otherwise.
* Your algorithm may decide to check more points if there is a diagonal wall.
* \return \c true if this point is on an obstacle.
