Detailed Description

GUI related to terraforming the map.

Definition in file terraform_gui.cpp.

Function Documentation

CommonRaiseLowerBigLand()

static void CommonRaiseLowerBigLand ( TileIndex  tile, bool  mode  )

static

Raise/Lower a bigger chunk of land at the same time in the editor.

When raising get the lowest point, when lowering the highest point, and set all tiles in the selection to that height.

Todo:

: Incorporate into game itself to allow for ingame raising/lowering of larger chunks at the same time OR remove altogether, as we have 'level land' ?

Parameters

tile	The top-left tile where the terraforming will start
mode	true for raising, false for lowering land

Definition at line 403 of file terraform_gui.cpp.

GUIPlaceProcDragXY()

bool GUIPlaceProcDragXY	(	ViewportDragDropSelectionProcess	proc,
		TileIndex	start_tile,
		TileIndex	end_tile
	)

A central place to handle all X_AND_Y dragged GUI functions.

Parameters

proc	Procedure related to the dragging
start_tile	Begin of the dragging
end_tile	End of the dragging

Returns

Returns true if the action was found and handled, and false otherwise. This allows for additional implements that are more local. For example X_Y drag of convertrail which belongs in rail_gui.cpp and not terraform_gui.cpp

Definition at line 112 of file terraform_gui.cpp.

PlaceProc_DemolishArea()

void PlaceProc_DemolishArea

(

TileIndex

tile

)

Start a drag for demolishing an area.

Parameters

tile	Position of one corner.

ResetLandscapeConfirmationCallback()

static void ResetLandscapeConfirmationCallback ( Window *  , bool  confirmed  )

static

Callback function for the scenario editor 'reset landscape' confirmation window.

Parameters

confirmed

boolean value, true when yes was clicked, false otherwise

Window* ShowEditorTerraformToolbar

(

)

Show the toolbar for terraforming in the scenario editor.

Returns
