Displaying velocity in joystick mode

[Reiko]

I notice when you get to about 100c the velocity counter switches to AU/s. Is there a way to keep it in percentages of C?
Also is there a way for me to make hot keys at what speed I want?

Not that I know of.

You can use F1 to F7 but they're fixed at the following speeds:

Code: Select all

F1: 0
F2: 1000 m/s
F3: 1000 km/s
F4: 1.0c
F5: 10.0c
F6: 1.0 AU/s
F7: 1.0 ly/s

I suspect you want to set a speed of your own choosing. The only way I know of doing this is with the CelX command "setspeed".

Code: Select all

-- SetSpeed script

myCustomSpeed= function()

  mly_conversion = 1.0563664635456286120030821283171e-10
  mps = 50000.0
  obs = celestia:getobserver()
  obs:setspeed( mps * mly_conversion )
  celestia:flash("Speed Set to: "..obs:getspeed()/mly_conversion.." m/s", 2)
 end

myCustomSpeed()


I think that the mly conversion may have changed in version 1.5.

I'm a star trek nerd and was wanting to have keys that represented warp drive speeds. Warp 1-9 etc.

I didn't realise how slow warp drive was until I left the solar system at warp 6.

CC, Reiko,

Chris has added event handling to Celx a while ago. You can use it to associate any key to the function of your choice. For example, using CC's example, you can write several CustomSpeed functions with different values for mps, and then associate them to different keys.

See http://celestiaproject.net/forum/viewtopic.php?t=9813 for more information.

Here's one I prepared earlier ... This uses a slightly older technique than that described by Vincent, however this means it will also work in 1.4.x versions.

Code: Select all

-- setCustomSpeedfunction script

setCustomSpeed= function()

  obs = celestia:getobserver()
  mly_conversion = 1.0563664635456286120030821283171e-10
  mps = 188.4955592  --(metres/second)
  obs:setspeed( mps * mly_conversion ) -- LY/s
  celestia:flash("Custom Speed = "..obs:getspeed()/mly_conversion.." ms", 2)
 end

keymap = { d = setCustomSpeed}

celestia_keyboard_callback = function(key)
     f = keymap[key]
     if f then
        f()
        return true
     end
        return false
 end

celestia:requestkeyboard(true)
repeat
     wait(60)
until false

To use this, just save the code above to a file name such as setCustomSpeed.celx.
Then run it from the File->Open Script menu in Celestia.
Thereafter, whenever you press the lowercase "d" key, it will set your speed to whatever you've entered on the line mps = 188.4955592
(until you press ESC, exit, or run another script)

Thank you guys!
Warp 5 here I go!

[Chuft-Captain]

May you "boldly go at speeds no one has gone before".

Reiko -

Don't know if you've seen this, but I'll post it for you anyway.

Warp Drive

Thanks! but I have seen that and go by the TNG warp chart. I like to use warp speeds to show other star trek fans how silly it is that they go from star A to star B in a flash.

[LordFerret]

I thought the second chart shown in that link was the TNG chart (Michael Okuda's new formula)? Is there a different / newer one?

Yeah you are right. That last chart is the one I have.

[Captain Nephilim]

A while back, for my own geeky fun, I created a table showing real world speeds compared to warp speeds, for reference in Celestia. I think my numbers are right, and no doubt someone will correct me if not.

The warp factor values are based on Okuda's numbers from the Next Generation.

[starfleetengineer]

No significant stellar motion can be observed in Celestia until approx WARP 9.9999998. ( = 70,220,261.5 x C = 2.23 ly/s )

... and I should know, because I'm a startfleet engineer


PS.
at WARP 9.99999985 (=805,579,078.5 x C = 25.5 ly/s) ...things start to get interesting
at WARP 9.9999999 (=242,037,562,178 x C =7670 ly/s ) ... say goodbye to the MilkyWay

starfleetengineer...

Is that to say Okuda's new formula as used and shown in the chart available at Wikipedia is the correct and current accepted definition?

It is. I looked in my star trek encyclopedia which is like a star trek bible
The okuda chart is what is used however they ignored it in star trek enterprise. Nobody knows what they used in that show.

I use a formula by Martin Shields.

[Captain Nephilim]

On another Star Trek/Celestia note: if you turn on constellation borders in Celestia, you'll see a sphere centered on Sol with a radius of 10 light years. According to a widely accepted definition, in Star Trek a "sector" is a cube 20 light years on a side. So the space inside the drawn constellation borders in Celestia is roughly equivalent to Sector 001 in the Star Trek universe. I often leave the constellation borders turned on while gallivanting about the galaxy, as a reference point.
