![]() They typically take the form of cave systems. Dungeon maps feature heavily in the Mystery Dungeon set of Pokémon games. The layout of a dungeon map is randomly generated every time it is entered. The same dungeon map will never have the same layout in successive visits. One drawback with dungeons is that they are quite plain, as by default they only use up to three different textures (floor, wall, void), and the only decorations are events. The dungeon generation code is all in the script section Overworld_RandomDungeons. #TINYKEEP DUNGEON MAP NAMES GUDWUSH CODE# Use the size of the map to determine how many cells it contains.Generate connections between the cells.Choose where the player enters the map.The map is divided up into cells, each of the same width and height. There is buffer space around the edges of the map, to ensure the player cannot get close enough to the edges to see the blackness beyond the map. This buffer space is defined in class Dungeon as the constants BUFFER_X and BUFFER_Y.Īfter subtracting the buffer distances from the map's width and height, the remaining sizes are divided by DungeonMaze::CELL_WIDTH and DungeonMaze::CELL_HEIGHT (rounded down). These two values are the size of a cell, and are both 13 tiles by default. Since the number of cells in each direction must be a whole number (hence the divisions are rounded down), the exact size of a map will not affect the dungeon's generation. Instead, there are ranges of map widths and heights corresponding to different numbers of cells. 41x37 tiles or smaller), then it will consist of a single room that is as large as possible. This room can be larger than any room generated in larger dungeon maps. The generator chooses a random cell (hereafter referred to as a node) to start at. The starting node is marked as "visited". ![]() Each of the four cardinal directions is randomly chosen in turn. ![]() For each one, if there is an unvisited node in that direction from the starting one, the two nodes are marked as linked, and then the same process described in this paragraph is repeated but with the new node as the starting node. If there are no unvisited nodes next to the starting node, the generator moves back to the previous node and continues checking each of its directions in turn. #TINYKEEP DUNGEON MAP NAMES GUDWUSH GENERATOR# In short, this is a depth-first recursive algorithm. It results in every cell in the map being connected to at least one other cell, where every cell can be reached from any other cell. There will not be any loops every pair of rooms will have exactly one way to travel between them.įor each cell, a corridor is drawn depending on how the cell connects to its neighbours. Then, for each cell, there is a 70% chance that a room will be drawn in it.
