Modules

ThicketScript comes with the pieces a game needs. They sit in layers, and you pick the ones you want:

Module	What it is	How you get it
willow	The 2D display tree: sprites, text, tweens, cameras, particles, tilemaps.	Built into thicket. List willow in systems.
willowui	UI widgets built on willow: buttons, lists, text input, windows, themes.	A package, written in ThicketScript.
gamekit	Game structure: entities, components, scenes, saves.	A package, written in ThicketScript.

Under all of them is the engine core: windows, input, audio and rendering. You never import it directly.

Systems and packages

The difference matters only in thicket.json. In your code, every import looks the same.

• A system is built into the thicket program. You list it in systems.
• A package is ThicketScript source from a folder, a git repository or a zip. You list it in packages. See Packages.

{
    entry: "app.tks",
    systems: ["willow", "bitmap"],
    packages: { willowui: "../willowui-tks" },
    window: { title: "My Game" },
}

Leave systems out and the project can use every system the host has.
