Script Doctor, help! I know it's imple but…

[MonsieurMeus]

Hi evreyone!

I'm quiet new in wrting scripts so I'm biginning with something very simple. I spend a lot of time in readins forum and testing scripts to understand how it works but I can't do what I'd like to. Coud somebody help me?
The idea is simple: we're watching the earth (orbit around) go to Hubble, look the machine and then go down to Marseilles/France as close as possible. Easy isn't it? I'm always having "jumps" or can't fin Hubble anymore or can't get closer. It's getting late here and I tried and tried, when I find something, something else is going wrong?€¦ Could somebody help me?
thanks in advance

1. to select Hubble you must use its full path:

Code: Select all

"Sol/Earth/Hubble"

2. Your script needs many more wait commands. You must specify

Code: Select all

wait {duration ... } # replace ... with an appropriate number of seconds

after an operation so that it has time to finish. Then you can tell Celestia to do something different. If it is not told to wait, Celestia will immediately start obeying the next command before the previous command has finished. Sometimes that will be what you want, but often it is not.

Hi!
Thanks for your help! Looks much better now! But a problem still remains. I always have "jumps" when I'm passing from one track { } to antother track { } untrack is not working in my script (Celstia 1.4.1), is there something else to have more smooth changement of orientation? maybe not using track? any idea?

[selden]

center { time ...}
follow {}

might work better for you.

[MonsieurMeus]

Thanks so much! Your help is a delivrance for me! I Love you!

have a wonderful day!
