Geometry Dash Asset Exporter

This script is made for exporting the image sheets in Geometry Dash (Ie WorldSheet, GameSheet, etc)

Setup

1. Download this script & Deno
2. Create an assets folder
3. Copy the respective .png and .plist for your asset into the folder
4. Run the script
5. Provide the name of the file without the extension
6. You're done, just check out the out folder

exporter.ts

import { parse } from "npm:fast-plist";
import { Image } from "https://deno.land/x/[email protected]/mod.ts";

const file = prompt(
	"Enter the name of the asset file in ./assets/ without the .png or .plist extension"
);

const returnTextFileIfExists = async (file: string) => {
	try {
		return await Deno.readTextFile(file);
	} catch {
		return null;
	}
};

const returnFileIfExists = async (file: string) => {
	try {
		return await Deno.readFile(file);
	} catch {

	}
};

		[key: string]: {

			aliases: unknown[];
			spriteOffset: string;

			spriteSourceSize: string;
			textureRect: string;
			textureRotated: boolean;

	Deno.exit();
}

// Just to make it easier to pass in .map
const parseNumber = (str: string) => parseInt(str);

let i = 1;
const assets = Object.keys(parsed.frames).length;

for (const [name, data] of Object.entries(parsed.frames)) {

	const [spriteX, spriteY] = data.spriteSize
		.replace(/[{}]/g, "")

	const sprite = new Image(spriteX, spriteY);
	const [textureX, textureY, textureW, textureH] = data.textureRect
		.replace(/[{}]/g, "")

		.map(parseNumber);

	const clonedSheet = sheet.clone();

	if (data.textureRotated) {
		sprite.resize(spriteY, spriteX);
		sprite.composite(clonedSheet.crop(textureX, textureY, textureH, textureW));
		sprite.rotate(90, true)
	} else {
		sprite.composite(clonedSheet.crop(textureX, textureY, textureW, textureH));
	}

	await Deno.writeFile(`./out/${file}/${name}`, await sprite.encode());
}

console.log("Done");
