Gridmap collision detection

fono

is possible to find the element of the gridmap who got collided with for example a bullet (area-->meshinstance - collisionshape). Otherwise is there a way to find the closest grid element near the collision point? I was thinking about rounding the collision coord to match the gridmap elements coord, but i don't want to reinvent the wheel if is already here.

You can probably get the closest grid element to a collision point using the world_to_map and get_cell_item functions. I have not tried it myself, but I remember reading this is a common way to find collided tiles in 2D with TileMap nodes. There might be a way to detect individual tiles, but I do not know of any right off. I did some quick Google searches and didn't find anything.
