is my tonight's request to Vincent (no, better, it's not a request, it's a pray!), asking for the same capabilities under cel scripts using Celestia 1.6.
Hope this may be useful, and if you think so (BTW, I use it for almost ALL my lessons scripts, successfully), please give me your help in asking for this improvement.
...And yes, I agree... Would be very nice to have in 1.6 when it becomes available.
Thanks for the information. Much appreciated. My approach will work, however. It's just harder to do.
You are VERY welcome, Bob.
And regarding your approach obviously it's working, but the most important differences are that using Vincent's patch you can have sound, too, and that to see the image you want, where you want on the screen, you don't need to move in the space to the billboard position, but you can show the same planet or moon and at the same time the image itself.
The only needed cel script lines for my example about the Ferrari, are:
Code: Select all
play { channel 0 volume 0.5 loop 1 filename "Ferrari_engine.wav" nopause 1}
overlay { duration 1.25 xoffset -0.612 yoffset 0.0 alpha 0.95 filename "ferrari.png" }
wait {duration 0.35}
play { channel 0 volume 0 loop 0 filename "" }
That's all: in the play line
“loop 1” means the sound will be repeated until the line command
play { channel 0 volume 0 loop 0 filename "" } will go on, while for the overlay line the xoffset and yoffset will position the image horizontally and vertically (with reference to the monitor center), while alpha will give the image transparency (from 1.0 fully opaque to 0.0 fully transparent).
BTW, you can use many sounds/musics at the same time, each on a different channel.
It’s a well checked and working way to add images, music, voices, sounds, and even movies, as I do in many scripts, using a series of images shown at very short time intervals.
Nice, plain, simple, and VERY easy to be remembered, isn't it?If you wish, think for comparison at the celx sequence of the command lines needed to make the same thing.
I have a pressing query: is there any important reason for which we cannot have all this in the official release of Celestia, given that Vincent has already done the patch for LUA tools for Celestia 1.5, and will do it for Celestia 1.6?
Chris?
If the reply will follow Fridger's assumption (correct, obviously) that in space there are no sounds or Beethoven music, well, believe me, despite this
it's a very useful and necessary component of the Celestia educational possibilities.Can you imagine Christophe's LEM on the Moon, without listening to Armstrong saying "A small step for (a) man..."?
Or looking at the Sputnik 1 without listening at its "Bip bip bip" I listened to personally and with an incredible emotion (I was 14 years old), half a century ago?
Or looking at the Orion shuttle docking 2001's Space Station, without Strauss’s Danube as background?
Please Chris, allow us to teach Astronomy in the best possible way, and possibly include Vincent's patch in the official release!
Thanks a lot.
My little cent.
Bye
Andrea
