Function Documentation

◆ AutoslopeCheckForAxis()

bool AutoslopeCheckForAxis ( TileIndex  tile,
int  z_new,
Slope  tileh_new,
Axis  axis 
)
inline

Autoslope check for tiles with something built along an axis.

E.g. railway stations and drive through road stops.

The test succeeds if the slope is not steep and at least one corner at either of the entrance edges is on the TileMaxZ() level.

Note
The test does not check if autoslope is enabled at all.
Parameters
tileThe tile.
z_newNew TileZ.
tileh_newNew TileSlope.
axisThe axis.
Returns
true iff terraforming is allowed.

◆ AutoslopeCheckForEntranceEdge()

bool AutoslopeCheckForEntranceEdge ( TileIndex  tile,
int  z_new,
Slope  tileh_new,
DiagDirection  entrance 
)
inline

Autoslope check for tiles with an entrance on an edge.

E.g. depots and bay road-stops.

The test succeeds if the slope is not steep and at least one corner of the entrance edge is on the TileMaxZ() level.

Note
The test does not check if autoslope is enabled at all.
Parameters
tileThe tile.
z_newNew TileZ.
tileh_newNew TileSlope.
entranceEntrance edge.
Returns
true iff terraforming is allowed.

◆ AutoslopeEnabled()

bool AutoslopeEnabled ( )
inline

Tests if autoslope is enabled for _current_company.

Autoslope is disabled for town/industry construction.

Returns
true iff autoslope is enabled.
