About

Aycblok (pronounced "ice block," but cooler) provides a set of procedural generators for creating sliding ice block puzzles.

The aim of the puzzles is for a player character to slide all push blocks onto a goal tile. Once pushed, the push blocks slide until they are stopped by an obstacle: either a permanent stop block, a break block that is removed when hit, or another push block. The player can move freely within non-obstacle or non-player void tiles and must be positioned directly next to a push block in order to push it in one of the cardinal directions. A push block is assumed to disappear when it is pushed onto a goal tile. The puzzle is complete when all push blocks have been pushed onto goal tiles.

The following is a move-by-move report as generated for one such puzzle:

Features

• Ice push block puzzle generation for a specified tile area.
• Input tile areas can have their tiles flagged to apply confining geometry to add challenge or visual interest.
• Support of multiple push blocks in a single puzzle area, which can interact and stop or block each other.
• Support of area obstacles such a holes by means of void tiles, which disallow traversal of a tile by the player, the push blocks, or both.
• Includes a random garbage block generator to clutter the area and make the solution less obvious.
• Customizable parameters for generation steps to help adjust the feel and difficulty of puzzles.

Generation Pipeline Example

The generation pipeline provides a way for multiple generation steps to be chained together. This is often easier than making manual calls to each generation step.

// Create a dictionary of arguments to be passed to each pipeline step.
var args = new Dictionary<string, object>
{
    { "PuzzleArea", new Array2D<PuzzleTile>(20, 20) },
    { "RandomSeed", new RandomSeed(12345) },
};

// Create a pipeline
var pipeline = new Pipeline(
    new PuzzleGoalGenerator(goalSize: new Vector2DInt(2, 2)),
    new PuzzleMoveGenerator(pushBlockCount: 3, targetPushCount: 20),
    new PuzzleGarbageGenerator(targetDensity: 0.1f, breakBlockChance: 0.5f),
);

// Run the pipeline and retrieve an output
var results = pipeline.Run(args);
var layout = results.GetOutput<PuzzleLayout>("PuzzleLayout");

Generation Logger Example

The generators include logging messages that can be subscribed to by adding a delegate to the Logger, as shown in the below example.

// Have the messages printed to the console.
Logger.AddListener(Console.WriteLine);

// Or added to a list.
var messages = new List<string>();
Logger.AddListener(messages.Add);

// Make sure to have your objects unsubscribe from the event to prevent memory leaks.
Logger.RemoveListener(messages.Add);
