Random dungeon generator algorithm
#RANDOM DUNGEON GENERATOR ALGORITHM GENERATOR#
Maps could be expanded or shrunk dynamically instead of being pre-defined, depending on how many rooms are being generated.Īll in all, though, this generator was very fun to write and put out there. Doors and rooms could be generated less haphazardly, adding to the flow between a room and the next. A decent room connecting algorithm could be used to generate better paths, guaranteeing you could go from one room to all the others. There are ways to make it better, however. It's not ideal, but it gives good results. You should have a dungeon generator similar to Aeldan's at this point. Be sure that you don't open a door from room 22 to room 31, and then from room 31 to room 22 - you need to check the reverse as well when figuring out if a door is valid. Once you're done with that, restart going through the list, but this time save only doors that open to other rooms rather than a path, with another twist: it doesn't matter if you have two doors in the South as long as they open to separate rooms. Save each door you find in a separate array. Each one of your list items is a valid door if you have not yet assigned a room to the same coordinate (N, S, E, W) and it opens to a path. A door is defined as the square it's positioned in and the N, S, E, W coordinate it has. Do this until you run out of squares or find enough doors. You will want to loop through the list after you randomize it and check possible squares for doors. If you place a door to the exterior in the North wall, exclude from valid doors all North walls in that room. We will also use random numbers to dictate the look of the.

We will only create tiles that the player discovers, which is a form of player-triggered PCG.

This algorithm will use two types of PCG.
#RANDOM DUNGEON GENERATOR ALGORITHM HOW TO#
Your list will be something like this: (1, 1, N), (1, 2, N), (1, 2, E), (2, 2, E), (2, 2, S), (2, 1, S), (2, 1, W), (1, 1, W).Ĭonsider how many doors you want per room (4 is okay, as not all will be possible), and create an empty array of positions you have excluded. Now that we settled on our data structure for managing our Game Board grid, we need to design our algorithm for placing tiles. How to code your own procedural dungeon map generator using the Random Walk Algorithm Ahmad Abdolsaheb As technology evolves and game contents become more algorithmically generated, it’s not difficult to imagine the creation of a life-like simulation with unique experiences for each player. If it is easier, just find all the possible squares in the room that open to N (the entire top file), then all that open to E (will overlap with N on the upper right), etc. Include in this list what position the door can be in: the top-left square of a room can have North and West doors, while a square on the right that isn't a corner can only have East doors. Add every outer square (every square of the room that touches a non-room area) to a list. Take your room x and y position and width and height values. You will need to loop through the rooms to create them, so the procedure below is for a single room. In this case, you will want to clean all path squares that have 1 or less path/room adjacent squares.ĭoors are relatively easy to add to your dungeon. Note: You can do the reverse as well, count from its neighbors how many are paths or rooms. Repeat this cycle whenever you find a path square that has to be emptied, and you will effectively clean all dead ends. If it has three or more neighbors that are empty, then mark that square as empty as well, and move forward. For every "path" square you find, check it's top, bottom, left, and right neighbors. The easiest way is to iterate through your matrix checking all squares. Paths that don't lead anywhere make for a messy dungeon, and it looks cleaner (and can be readjusted to make a basic city) if the dead-end paths can be fixed. There is a way to create a lot of presets, but I want to implement a method that automatically creates dungeons to reduce the effort of human editing. Due to the nature of the genre, dungeons must be recreated for every play. If you have followed the previous step of generating the paths in a somewhat random manner, then you will realize that this leaves a lot of dead ends. The P3 (code-name, no name yet) is a game in the genre of rogue-like dungeon crawler. It doesn't cover the basic generation of content, if you're looking for how to generate a dungeon, start there.

To keep things simple, I want to have a plugin that will randomly generate a dungeon in lieu of mystery dungeon games, rogue, and the like.This article is the sequel to Dungeon Generator Algorithm: Part I.
