Can scripting move your view forward in straight line?

[fsgregs]

Hi all:

I am working on an exciting add-on controlled by a script, and I have been searching for a way to move my view forward in a straight line, much as you might do in Celestia by pressing the [A] key and moving your view independently of any orbits or other objects.

I have not found any script commands that duplicate the [A] key. Maybe I'm just missing them.

Are there any? If so, how would they be used?

Thanks in advance.

Hi Frank,

You can use the following celx code to set the speed of the observer:

Code: Select all

speed = 1e-4 -- in microlightyears/s
obs = celestia:getobserver()
obs:setspeed(speed)

Thanks, Vincent. I will use your 3 lines when needed in celx scripts to move the view in a particular direction.

Is there something similar for use in cel scripts? I see there is a command called "Move". I have not used it and while I read the brief comment about the command on the Scripts cel WIKI, I don't really understand what parameters it would use, or how to use them. It seems like it would allow a script writer to move their view in a particular direction.

If true, could you provide a short descriptive example of what a "Move" command line would look like?

Thank you

Frank,

the move command should look like

Code: Select all

move { duration 10 velocity 10000 }

Duration = sec.
Velocity = km/s
