Reinitializing Celestia to Its Factory Default State

[TJackson]

Can anyone tell me the proper way to reinitialize Celestia to its factory/installation default state (preferably via script), short of uninstalling it from Windows and reinstalling it? I wrote a simple script and now for no reason that I can pin down, I cannot now get it to function as it did anymore.

Actually, I'm finding that, even after an uninstall and a reinstall, my script still won't function as it used to.

What exactly isn't working correctly now?

This script used to land on Earth and then zoom in on Io quite nicely. Now it only brings up a black screen. Pressing '~' doesn't bring up any debug info. I'm stumped.

observer = celestia:getobserver()
EarthObject = celestia:find("Earth")
observer:gotosurface(EarthObject)
observer:gotolonglat(EarthObject, -84.3880, 33.7490, 0.1)

Observedbject = celestia:find("Io")
observer:track(ObservedObject)

observer:setfov(math.rad(0.001))

newTime = celestia:tojulianday(2021, 12, 30, 00, 05, 6.0)
celestia:settime(newTime)


Your original instructions still work, of course:

To go to a specific location on Earth:
"Navigation" menu -> "Goto Object"
Go to Earth at the latitude and longitude you want
Press Ctrl+G to land
Press Ctrl+F to enable alt-azimuth mode

To view a planet or other object at high magnification:
Select the object and press T to track it (keep it centered on the screen)
Use the , key to decrease the field of view (you can also use . to increase the field of view)

You have a typo; this

Observedbject = celestia:find("Io")
observer:track(ObservedObject)

should be

ObservedObject = celestia:find("Io")
observer:track(ObservedObject)

After correcting this, the script works for me (if it's intended to immediately switch to a view of Io).

I'm so embarassed I didn't catch that. And you've been so helpful and polite. I'll give you a bit of a rest now, SevenSpheres. How may I recommend you for an increase in Celestia rank?

[TJackson]

The failure to catch the typo was indeed my fault. However, that points to a deficiency (or room for improvement) not only in me but also in Celestia. Operating systems provide crash reports, debuggers report execution errors, and compilers report syntax errors for a reason. It would certainly be a helpful feature for Celestia to somehow indicate the presence of that typo (or anything ELSE that it can't execute in a running script). I was disappointed to find that the '~ debug console' feature does not (that I can determine) include any information about a running script. Maybe it should. If so, where should I propose/request/suggest that addition? The Wiki? The Development subforum? The Bugs subforum? Thx

Definitely one of the latter; GitHub would be even better. Wikibooks is for documentation, not requesting features.
