## Function Documentation

static bool AutoslopeCheckForEntranceEdge | ( | TileIndex | tile,
|  | uint | z_new,
|  | Slope | tileh_new,
|  | DiagDirection | entrance |
| ) |  |  | `[inline, static]`

Autoslope check for tiles with an entrance on an edge.

E.g. depots and non-drive-through-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:

  | tile | The tile.
  | z_new | New TileZ.
  | tileh_new | New TileSlope.
  | entrance | Entrance edge.

Returns:
  true iff terraforming is allowed.
