Celestia Forums

I'm new to Celestia; about a month. I've been "playing around" with it and recently tried writing my own start.cel script. I've experimented (trial&error) with all the commands I could find. I was able to use and generally understand all the commands except one...

The "MOVE" command wasn't working for me. Help with instruction will be appreciated. Also, I copied the script commands from the shatters page....are there any other commands or interesting suggestions on script writing not included at "http://ennui.celestiaproject.net/celestia/docs/scripting.html"?

below is my first try at a complete startup script. You'd probably want not to use it as a start.cel because It's a bit long. I wanted to try a "cool" fly-by of the Ikeya-Zhang comet on the way to Earth, but I didn't get the results I was hoping for.

I just remembered another question... How to reset the time within a script to "current time"?

How to turn on-off the Celestial-Grid within a script?

Thanks for writing Celestia.

below's the script I tried but was hoping the "MOVE" or any other suggested command would work better as a fly-by of Comets etc...
