◆ CcPlaceSign()

void CcPlaceSign	(	Commands	cmd,
		const CommandCost &	result,
		SignID	new_sign
	)

Parameters

result	of the operation
new_sign	ID of the placed sign.

◆ CmdPlaceSign()

std::tuple< CommandCost, SignID > CmdPlaceSign	(	DoCommandFlags	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

tile	tile to place sign at
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	(	DoCommandFlags	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
