# Toy night sky written in the "freewheeling" style that can be modified without being restarted
[](https://0dependencies.dev)
This app shows a very simple animation of a rotating night sky containing some
twinkling stars with a subtle oscillation between day and night. It's intended
as an example app for playing with the [the driver app](https://codeberg.org/akkartik/driver.love).
[What is a Freewheeling App?](http://akkartik.name/freewheeling)
[There's some reference documentation if you're inspired to create your own apps.](reference.md)
## Invocation
Run this app from the terminal, [passing its directory to LÖVE](https://love2d.org/wiki/Getting_Started#Running_Games)
## Hacking
To modify it live without restarting the app each time, download [the driver
app](https://codeberg.org/akkartik/driver.love). An example session might look
like this (though the UI of the driver app on the left is improving over
time):
To publish your changes:
* delete all files with a numeric prefix from the repo, and then
* move all files with a numeric prefix from the [save directory](https://love2d.org/wiki/love.filesystem.getSaveDirectory)
to the repo.
## Known issues
* This approach puts one top-level definition per file, and so obscures the
order in which definitions are loaded. In particular, initializing a global
table to contain other global definitions will fail if you originally
authored the other global definitions after the table.
I never initialize global tables with other definitions. That kind of thing
happens in `on.initialize` (akin to `love.load`; see reference.md) or
`on.code_change`.
* Don't start the driver app while multiple freewheeling apps are running. If
you have a driver app running with one app, shut it down before you switch
apps.
