Dungeon generator

Create a procedurally generated dungeon. Includes two layouts: "rooms and hallways" and "dungeon cave".

Authors and contributors to this community extension: VictrisGames, oscuridad666.

How to use:

Run the "Generate Dungeon Cave" or "Generate Dungeon with Rooms" action at the beginning of a scene.

Tips:

Keep the amount of space used by room objects to less than ~25% of the total map. If you add too many rooms, they will not be placed correctly and might collide with other rooms.
Try using top-down controls combined with physics behavior (with no gravity) on the player and wall objects
Use external layouts to place pre-designed rooms on randomly created room objects
Use "Delete Unused Terrain" option to reduce resources used
Use "RoomID(object)" expression to determine the starting and ending room
Use "NeighborCount(object)" expression to find good places to place treasure. A high amount of neighbors means that the tile is a nook or cranny.
Use "IsRoomEntrance" condition to identify hallway objects that are adjacent to a room

An example shows how to procedurally generate dungeons or caves (open the project online).

Actions

Calculate the number of grid neighbors around an object
Calculate the number of grid neighbors around an object. Use "NeighborCount(Object)" expression to retrieve this value.

Generate a dungeon cave
Generate a dungeon cave using a random walk algorithm. When the walker touches an edge of the map, it is moved back to the center of map.

Generate a dungeon with room and hallways
Generate a dungeon by placing rooms in random locations and moving them if they collide with each other. Rooms are connected with hallways.

Conditions

Hallway is a room entrance
Check if hallway is a room entrance.

Expressions

Expression	Description
`DungeonGenerator::NeighborCount(object)`	Number of grid neighbors of an object. Requires running the "CalculateGridNeighbors" action before using this expression.
	object	Object
`DungeonGenerator::RoomID(object)`	The numerical order this room was created. (Range: 1 to total number of rooms).
	object	Room object
