About This Tool

The tool generates a grid-based tileset by combining tile_size_px, grid dimensions, and a selected color palette. It supports deterministic variation via an optional seed, enabling reproducible assets across builds.
Conceptually, the generator assigns colors to a two-dimensional grid and assembles tiles into a single spritesheet. It can export a PNG spritesheet and a companion atlas JSON that maps each tile to its region within the sheet. This supports engines like Unity, Godot, and Unreal in tile-based workflows.
Audience includes solo developers, small studios, and artists who need consistent, repeatable tiles without manual painting. Unique value comes from deterministic palette-driven tiling, straightforward exports, and predictable tile indexing. Core features include tile_size_px presets (8/16/32), grid dimensions, palette hex colors, optional seed, optional edge handling, and export formats; advanced features like transparency and edge smoothing are supported via export options.

How to Use

Provide inputs: set grid width/height in tiles, tile size, and select a color palette.
Optionally set a seed for deterministic variation.
Generate the tileset to create a PNG sprite sheet and atlas JSON.
Review the atlas to map tile indices to positions.
Export PNG and atlas for engine import.
Import into your game project and reference tiles by ID.

Frequently Asked Questions

Find Quick Answers

What formats are exported?

The tool exports a PNG sprite sheet containing all tiles and a JSON atlas that maps each tile to its rectangular region within the sheet. Additional metadata can be produced on request.

Can I generate animated tiles?

The generator creates static tilesets. You can produce multiple variants with different seeds or palettes and animate tiles at the engine level, using the separate animation features there.

Does it support transparency?

Yes. PNG exports preserve per-pixel alpha, enabling transparent tile regions. The atlas JSON includes width and height for each tile to assist proper rendering.

What tile sizes are supported?

Common presets include 8, 16, and 32 pixels. Inputs are validated, and you can adjust grid dimensions to fit the chosen tile size. Larger sizes reduce tile count on the sheet.
