Extrude Tilesheet Tool

This repository contains a script for Aseprite that helps you extrude tiles in a tilesheet. This is particularly useful for game development, where you need to avoid texture bleeding.

This script is a direct port of the Tileset Extruder by sergiss's Javascript web app to Lua for Aseprite.

Features

• Extrudes tiles in a tilesheet to prevent texture bleeding.
• Easy to use with Aseprite.
• Customizable extrusion size.

Requirements

• Aseprite v1.2.10 or later.

Installation

1. Download the extrude-tilesheet.lua script.
2. Open Aseprite.
3. Go to File > Scripts > Open Script Folder.
4. Copy the extrude-tilesheet.lua script into the folder.
5. Restart Aseprite.

Usage

1. Open your tilesheet in Aseprite.
2. Go to File > Scripts > extrude-tilesheet.
3. Enter the amount of columns and rows.
4. Enter the desired extrusion size in pixels.
5. Run the script to extrude your tiles.

Known issues:

• After generating the extruded tilesheet, the color palette of the generated "sprite" will be entirely filled with black.
  • Workaround: Palette Options > New palette from sprite will re-generate a new palette from the sprite.
