Spring RTS Engine

I can't seem to figure out how to create a Toggable GUI.
Ive fixed the TA Music widget but i want to add a slider for the volume level.
To be honest i don't even know where to start.
This is the code ive got to play a sound file with a set volume. but i want to change it to something like this. Could i have the input of the slider something like this.. See i dont even know how to add the mouse control or how the slider will interact with the code above.

So i desperately need some help.

Thanks

create a local variable which stores playback volume, attach a command handler to set such variable, such as

/luaui musicvolume 0.8

then make a copy of the volume bar widget, and change the source so instead of changing spring game volume it sends the aforementioned command passing the silder % value

I can't find the volume bar widget anywhere. I havn't got it nor can i find it on the web to download it.

Here is a link:

Or use viewtopic.php?f=23&t=15280 .. You can pretty much use what you posted in the first post and add a options = { ... } around it and you're done.. I'd really like to know why noone seems to like it..

Does the current TA Music widget not work at all with .77b5? I just tried it out, and no music is playing. If this is the case, I assume you are fixing it for this obvious reason, in which case I can't wait for you to finish :-D

Huh. You know, I looked at the LUA file for the TA Music widget, and changed every instance of Spring.PlaySoundStream(blah blah blah) from 0.5 to 0.7, and the widget now seems to be working. I have TA music again!
