Using Seed Variables

This Plugin uses a seedable randum number generator to generate worlds. This way dungeons can be created the same way when a player re-enters them – if you wish. This article shows some examples:

Randomize everytime the Player enters

If you want the dungeon to be randomly generated everytime the player enters it, uses this command right before you call the generator.

var seed = Math.Floor(Math.random() * 100);
$dungeonGenerator.setSeed(seed);

Use Seed Variables (persisted Map)

A more natural way to generate dungeons would be, that when a player leaves a dungeon to go to the world map, and then re-enters it, it still looks the same. For my own game project I use this strategy: When a new game is started, a globally seed variable is randomly chosen once and then stored for this save slot. When the player leaves the world map to visit a dungeon, then his X and Y coordinates are also used to feed the generator. While the player is inside a dungeon, he cannot save his progress. Storing this variables is done by using standard event commands as this is much more convenient.

Storing the Global Seed

Once the game starts, we call a “Change Variable Operation” to set a global variable called “Seed” with a random number.

Storing the X and Y Coordinates

As soon as the player wants to enter a dungeon from the world map, we memorize his position and store his X and Y coordinates.

Feeding the Generator and Finalize

Get a new seed variable by using this command:

var seed = $gameVariables.value(1) * $gameVariables.value(2) * $gameVariables.value(3) % 100;
$dungeonGenerator.setSeed(seed);

While the numbers 1, 2 and 3 stand for ist respective ID in the global variables. Ensure to set them correctly. Feel free to add more variables or leave some out if you wish.
