	Sprites for slopes are always in the same order in TTD. For example, <code style="color:darkgreen">GROUND_SPRITE_NORMAL</code> is the sprite number of a flat grass tile. It is followed by 18 other sprites, that display a flat grass tile for each possible slope. The order of these sprites is given in the last column of the table. The [[NML:Builtin functions\|builtin function]] <code style="color:darkgreen">slope_to_sprite_offset(''slope'')</code> can be used to determine the sprite offset of a given slope.

Tiles in TTD can have various slopes. The slope is a bitmask that may contain the following bits:

{| class="t"
! bit flag
! meaning
|-
| CORNER_W
| west corner is above the lowest corner.
|-
| CORNER_S
| south corner is above the lowest corner.
|-
| CORNER_E
| east corner is above the lowest corner.
|-
| CORNER_N
| north corner is above the lowest corner.
|-
| IS_STEEP_SLOPE
| this tile is a steep slope (the corner opposite to the lowest corner is 2 units higher).
|}

The resulting, possible values of this bitmask are given in the following table. The image below that illustrates them graphically. See also the [[NML:Builtin functions|builtin function]] <code style="color:darkgreen">num_corners_raised(''slope'')</code>.

Sprites for slopes are always in the same order in TTD. For example, <code style="color:darkgreen">GROUND_SPRITE_NORMAL</code> is the sprite number of a flat grass tile. It is followed by 18 other sprites, that display a flat grass tile for each possible slope. The order of these sprites is given in the last column of the table. The [[NML:Builtin functions|builtin function]] <code style="color:darkgreen">slope_to_sprite_offset(''slope'')</code> can be used to determine the sprite offset of a given slope.
