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.

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.

cell: The cell to flood with. This does not have to be a fluid cell.


generator.setup_deadly_air_event(integer step)

Runs the setup script for the deadly air event.

step: Number of turns between each "chill" (loss of HP).


generator.setup_explosion_event(integer step, integer size, integer dice, integer [content])

generator.setup_explosion_event(integer step, Table size, integer dice, integer [content])

Runs the setup script for the explosion event.

step: Number of turns between each explosion.

size: Either a number or a table of two numbers. Indicates the size of each explosion. If a table is supplied, the size is randomly chosen between the range supplied each time an explosion is created.

dice: Number of d6 dice to use for the damage roll.

content: Optional. The content to place in any space where the damage to a space is more than 20 points. If omitted, nothing will placed.


generator.setup_targeted_event(integer step)

Runs the setup script for the targeting event.

step: Number of turns between each monster teleport.

 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 [[Modding:Constants|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.
