This page is currently under construction.
The generator holds all of the ever-present functions used to create the random maps in DoomRL. It also contains a variety of helper functions, many of them useful if not vital to the creation of intricate and meticulous game design.
API
Please note that the type "integer" indicates an numeric value without a decimal part. It does not indicate the range of acceptable values.
The argument type "CellID" may be the numeric or string ID of a cell.
The argument type "CellSet" may be the numeric ID, string ID, or a list of numeric and/or string IDs.
The argument type "Flags" expects a list of flag constants of the indicated type.
An argument name in [square brackets] is an optional one. The function description will indicate how the function operates if it is omitted.

- count: Optional. The number of attempts. If omitted, the default is 50.
- special_chance: Optional. A number indicating the probability of using a special list of cells to fill the square with instead of the fill list. The roll used for the chance is based on the size parameter. A number from 1 to (100 * size) is chosen for each square and if the roll is less than the special_chance number, the special cell set is used to fill the square instead. If omitted, all squares will be filled from the fill set.
- special: Optional. The list of cells to use if the special set is to be used, based on special_chance. If omitted, all squares will be filled from the fill set.

- start: The position to start the blob at.
- size: The number of spaces to expand the blob to.
- cell: The cell to fill the blob area with.
Generator Helper Functions
- generator.roll_pair(Table list) → <value>, <value>
Takes a list of values of any type and returns two different values randomly from the list.
- list: The list to choose from.
- Returns: Two different values. If the list only contains one choice, it will be returned, but only once.
- generator.being_weight()
Gets the total danger level for the current dungeon level. Returns: The danger level for the current dungeon level. This value is calcuated using the current difficulty and level.danger_level.
- generator.item_amount()
Gets the number of items to drop for the current dungeon level. Returns: The number of items to drop for the current dungeon level.
- generator.horiz_river(CellID cell, integer width, boolean [bridge])
Places a horizontal river on the map.
- cell: The cell to use for the river. It does not have to be a fluid cell.
- width: The width of the river.
- bridge: Optional. If True, a 2 space wide bridge will be placed at a random coordinate on the river. If False, no bridge will be placed. If omitted, the default is to not place a bridge.
- generator.vert_river(CellID cell, integer width, boolean bridge, integer [position])
- generator.vert_river(CellID cell, integer width, boolean bridge, Coord [position])
Places a vertical river on the map.
- cell: The cell to use for the river. It does not have to be a fluid cell.
- width: The width of the river.
- bridge: Optional. If True, a 2 space wide bridge will be placed at a random coordinate on the river. If False, no bridge will be placed. If omitted, the default is to not place a bridge.
- NOTE: Because of a bug, a bridge will always be placed on the river, even if this value is set to False or omitted.
- position: A coordinate or an integer. If an integer is supplied, this is the X position of the river's left edge. If a coordinate is supplied, the river will start at this coordinate. If omitted, the river's left edge will be selected from between X = 19 to 58.
- generator.generate_rivers(boolean allow_horiz, boolean allow_more)
Creates rivers based on normal DoomRL river generation.
- allow_horiz: True allows horizontal rivers to be generated. False will prevent the generation of horizontal rivers.
- allow_more: True allows multiple vertical rivers. False will prevent more than one vertical river from being placed.
- generator.generate_fluids(Area [where])
Creates fluids based on normal DoomRL fluid generation.
- where: Optional. The area to generate fluids in. If omitted, the area used will be the entire map minus the very edge.
- generator.generate_barrels()
Creates barrels based on normal DoomRL barrel generation.
- generator.generate_stairs()
Creates the normal staircase based on normal DoomRL stair generation.
- generator.generate_special_stairs()
Creates the special staircase based on normal DoomRL special stair generation. Whether a special staircase is placed depends on the level.special_exit value.
- generator.place_player()
Places the player on a random empty space.
- generator.run(Generator gen)
Runs a generator object. These are stored in the generators table.
- gen: The generator object to run.
- generator.reset()
Resets the map.
Dungeon Generation Functions
- generator.generate_tiled()
Creates a tiled dungeon, also known as a "normal" dungeon. This only creates the layout, it does not place beings, items, stairs, barrels, or the player.
- generator.maze_dungeon(CellID floor, CellID wall, integer granularity, integer tries, integer min_size, integer max_size)
Creates a maze dungeon. This only creates the layout, it does not place beings, items, stairs, barrels, or the player.
- floor: The cell to use for the floor of the maze.
- wall: The cell to use for the wall of the maze.
- granularity: This denotes the size of the maze's paths.
- tries: Number of attempts to place a new wall in the maze.
- min_size: The smallest possible size of a wall.
- max_size: The largest possible size of a wall.
- generator.generate_caves_dungeon()
Runs the generation script for the cave dungeon. This is an all inclusive function, it also places all beings and items.
- generator.generate_caves_2_dungeon()
Runs the generation script for the cave-city dungeon. This is an all inclusive function, it also places all beings and items.
- generator.generate_lava_dungeon()
Runs the generation script for the lava dungeon. This is an all inclusive function, it also places all beings and items.
Event Handler Functions
- generator.roll_event()
Picks an event from the events table and sets it up.
- generator.setup_flood_event(integer direction, integer step, CellID cell)
Runs the setup script for the flood event.
- direction: Use 1 to flood from the left. Use -1 to flood from the right.
- step: Number of turns (0.1 second intervals) between each flood step.
