Try cranking up the number of iterations!Īfter playing around with the different options available, I’ve settled on using an initial chance of 0.45, a survival threshold of 4, and a birth threshold of 5. Like last time, building a little tool helped a lot.
#Dungeon generator algorithm how to#
I didn’t pop out of the womb with a well-developed intuition for how birth and survival thresholds affect the shape of caves generated by a cellular automaton, and so I had some trouble figuring out how to proceed when I got to this point. This problem is one of the most interesting things about procedural level generation - whenever you’re evaluating an algorithm, you’ve got to figure out what its inputs are, and try to develop some understanding of how you can manipulate those inputs to get the type of levels that you want.

Well, it sure looks like that code is doing something to our grid, but it’s not easy to tell how we can use this to generate a cool cave like the one we saw at the beginning of this article. (generate-grid width height initial-probability)) (recur (assoc-in new-grid new-value)īirth-threshold survival-threshold iterations] That’s all the groundwork we need - let’s implement the algorithm! (>= alive-neighbors birth-threshold)) :alive (>= alive-neighbors survival-threshold)) :alive Now that we’re able to count how many of our neighbors are alive, let’s figure out how to determine a cell’s new value at each step of the simulation. In addition to the draw-grid function from last time, I’ve supplied a draw-grid-highlighted function that lets you see what your cell’s neighbors look like. Now let’s write a function that finds a given cell’s neighbors. (As a bonus, this rule tends to give our levels nice solid walls around the edges.) (spot-is-off-grid? (generate-grid 5 5 0.5) -1 0)įor simplicity, we’ll say that these nonexistent neighbors are considered to be alive. (.rect (* cell-width (dec x)) (* cell-height (inc y)) (* 3 cell-width) cell-height) (.rect (* cell-width (inc x)) (* cell-height y) cell-width cell-height) (.rect (* cell-width (dec x)) (* cell-height y) cell-width cell-height) (.rect (* cell-width (dec x)) (* cell-height (dec y)) (* 3 cell-width) cell-height) (if (identical? (inc x) width) (inc y) y)))))) (recur (if (identical? (inc x) width) 0 (inc x)) (.rect (* x cell-width) (* y cell-height) cell-width cell-height)
(.clearRect ctx 0 0 canvas-width canvas-height) (let [canvas (js/document.getElementById (.getContext canvas "2d") The algorithm starts by generating a grid of these cells, each of which has a certain chance of being alive. (An alive cell is a cave wall, and a dead cell is empty space where the player can move around freely.) We tried 1000ff7de8 s of rooms in single dungeon.We’re still using a 2D grid to represent our level, but we’ll be using some new vocabulary this time.
Generating start prefab (usually your player prefab) and exit point.Ĭustomizable room sizes and count. And we are doing this very well:)Ĭurrent features: You can use Dungeonizer to create dungeons in editor mode or on the fly.Īble to use your own walls and floor prefabs. Our purpose is creating a very basic and customizable algorithm for low budget games.
