add ActionID to tile

[Shitobu]

I've been trying to add an actionID on a player's tile.
I've tried this way:

local tile = player:getTile()
    tile:setActionId(111)

But it returns nil.
I guess my problem is on getting the tile itself. What is the problem?
Thanks!

local tile = Tile(player:getPosition()):getGround()
if ground then
    ground:setAttribute(ITEM_ATTRIBUTE_ACTIONID, 111)
end

If you don't mind, can you explain me how this line works?

local tile = Tile(player:getPosition()):getGround()

It's okay if you can't.

You have to retrive the ground, which will return a item.
