How can I slow do the "Go to" speed?

Is there any way to slow down the travel speed? I travel from outside the Milky Way to the sun so fast I can hardly see it!

I think Celestia could certainly use improved velocity measurements and indicators. Setting the "go to" speed, for one, as well as setting a non-"Go to" speed. Perhaps a dialogue box which asks us for a velocity, lets us select units, and after pressing "Okay" or "enter" or whatever, the observer assumes that speed.

This can be done quite simply with a celx script:
Now, as an exercise, you can try making the duration vary according to the distance from the target...
Code: Select all
-- Title: Slower Goto command
-- Modify the following value to your specific needs:
duration = 20
function slowGoto()
sel = celestia:getselection()
obs = celestia:getobserver()
obs:follow(sel)
obs:goto(sel, duration)
end
keyhandlers =
{
g = slowGoto
}
function handlekey(k)
handler = keyhandlers[k.char]
if handler ~= nil then
handler()
return true
else
return false
end
end
celestia:registereventhandler("key", handlekey)Now, as an exercise, you can try making the duration vary according to the distance from the target...

In fact all of the celx commands goto, gotolonglat, gotolocation, gotodistance, gotosurface, center, and centerorbit have a duration component.

Do we have to enter a value for getselection? If so, what do we enter?

getselection() automatically returns the current selection.
So, users don't have to enter any value. Did you meet any problem
with this script?

The script worked just fine. In fact, it works so well that I would love to see it active all of the time, whenever I launch Celestia 1.5.0.
To the best of my knowledge, Celestia can only run one celx script at a time. So, if I have the slowgo script active and I want to launch a new script, I guess slowgo.celx stops functioning as soon as the new celx script launches. Is that correct? If so, is there a way to incorporate it into the celestia.cfg file, or somehow keep it active as long as 1.5.0 is running, no matter what other scripts are launched?

To do so, you just need to save the following script as start.celx, and set InitScript "start.celx" in celestia.cfg:
Code: Select all
-- Modify the following value to your specific needs:
duration = 20
function slowGoto()
sel = celestia:getselection()
obs = celestia:getobserver()
obs:goto(sel, duration)
end
keyhandlers =
{
g = slowGoto
}
function handlekey(k)
handler = keyhandlers[k.char]
if handler ~= nil then
handler()
return true
else
return false
end
end
celestia:registereventhandler("key", handlekey)
function CEL(source)
local script = celestia:createcelscript(source)
while script:tick() do
wait(0)
end
end
CEL([[
{
# ... Beginning of script
# PASTE YOUR WHOLE STANDARD START SCRIPT HERE
# End of standard script...
}
]]) Re: How can I slow do the "Go to" speed?

ThAT WORKED FINE AGAIN. Thank you. Now, my start.celx script has a configurable value for how fast the go to command is. What a wonderful feature.
I suggest that it is so useful it should be put into celestia.cfg as a variable, or incorporated into Celestia's default start.celx.

Really nice . I tried both possibilities; both work fine.
I think, I will let the start cel as default and select the slow goto by selecting the script.
Thanks a lot, Vincent !
