CmdPlaceSign()

std::tuple< CommandCost, SignID > CmdPlaceSign	(	DoCommandFlag	flags,
		TileIndex	tile,
		const std::string &	text
	)

Place a sign at the given coordinates.

Ownership of sign has no effect whatsoever except for the colour the sign gets for easy recognition, but everybody is able to rename/remove it.

Parameters

flags	type of operation
text	contents of the sign

Returns

the cost of this operation + the ID of the new sign or an error

CmdRenameSign()

CommandCost CmdRenameSign	(	DoCommandFlag	flags,
		SignID	sign_id,
		const std::string &	text
	)

Rename a sign.

If the new name of the sign is empty, we assume the user wanted to delete it. So delete it. Ownership of signs has no meaning/effect whatsoever except for eyecandy

Parameters

flags	type of operation
sign_id	index of the sign to be renamed/removed
text	the new name or an empty string when resetting to the default
