This is a list of tile types that can be changed on a levels tile map to create the space Hacker can walk in. Tiles can be changed by modifying their Tile Properties by selecting one or multiple in the Level Tiles window.

Solid , Open and Diagonal tiles all have a flat Floor and Ceiling and they should not have a Slope Control other than CeilingInverted set. Never set a Slope Height other than 0 to these Tile Types because the height of the slope, which they don't have, will be added to their Floor- and Ceiling-height.

By default, all 64x64 tiles of a level (except Level 1) are solid and Hacker can't walk inside it. Outer tiles of a Levels tile map should stay solid to avoid glitches and crashes.

By default, the only open tile after clearing a levels tile map is created on Level 1 at T=30/22 and is the tile in which a new default game begins (The starting position can be overriden in special engines. See New Game State). Hacker can walk in the open space these tiles create.

Diagonal Open are triangular half open / half solid tiles. Which half is open is defined by the last direction of their names:

• DiagonalOpenSouthEast
• DiagonalOpenSouthWest
• DiagonalOpenNorthWest
• DiagonalOpenNorthEast

Slope Tiles have both Floor or Ceiling or either but not the other formed as a ramp. The Level Tiles window got additional tile properties that can be modified to change a slopes behaviour:

• The steepness of the slope is set by changing the Slope Height value
• Modifying Slope Control allows to set the dependency of the slope between Floor and Ceiling
  • CeilingInverted sets slopes on opposite sides of a tiles Floor and Ceiling.
  • CeilingMirrored sets slopes on the same side of a tiles Floor and Ceiling.
  • CeilingFlat sets a slope on a tiles Floor but not on Ceiling.
  • FloorFlat sets a slope on a tiles Ceiling but not Floor.

In which direction the uphill direction of a slope lies is defined by their names:

• SlopeSouthToNorth
• SlopeWestToEast
• SlopeNorthToSouth
• SlopeEastToWest

Valleys are another form of Slope Tiles with 3 corners higher than the fourth. In which direction/corner the highest point of a valley lies is defined by their names:

• ValleySouthEastToNorthWest
• ValleySouthWestToNorthEast
• ValleyNorthWestToSouthEast
• ValleyNorthEastToSouthWest

Yet another form of Slope Tiles, Ridges have 1 corner higher than the other 3. In which direction/corner the highest point of a ridge lies is defined by their names:

• RidgeNorthWestToSouthWest
• RidgeNorthEastToSouthWest
• RidgeSouthEastToNorthWest
• RidgeSouthWestToNorthEast

On the editors tile map, green and red triangles in the corners symbolize sloped tiles. Green triangles indicate the highest point of a sloped Floor and red ones indicate the lowest point of a sloped Ceiling.
