Sound in UI; Smooth Lines

[Gravedigger]

hei wjpiovano
a whole bunch of questions! :D

1. Is there any way to play a .mp3 (or any format) file when a button is pressed?

-> you can write a script which opens the mp3 file. you can use the system command to do this:

system("start file.mp3");

well the problem is that it'll open in your standard audio player.

2. Is there a way to create a smooth curved line (like a spline curve) out of only 3 points? I want to make a smooth random line without specifying a dozen points.

->yes you can. you have to go to the options of the cv curve tool and change the degree to 2.

3. Can you call rand with a variable? e.g. rand $var. Maya seems not to like it; if not, is there any way around it?

-> i have no problems using rand with a variable:

int $var = 10;
print (`rand $var`+"\n");

this works fine for me

hope this helps!

Hey there! Thanks for the useful replies.

I think I was doing something strange (or going crazy). Rand does in fact seem to work. =D

I have the misfortune of having Maya PLE which doesn't support 'system' or 'exec'. Do you happen to know any possible ways around it?

Thanks again!

Check the MEL documentation for sound.
I found this here...

// Create an audio node for a sound file, and have it
// start at time 10. This command will return the name
// of the created node, something like "audio1".
//
sound -offset 10 -file "ohNo.aiff";

// In order to have this sound displayed in a
// timeControl widget (like the timeSlider) use a
// command like this one, where the global MEL variable
// $gPlayBackSlider is the name of the widget to display
// the sound in.
//
global string $gPlayBackSlider;
timeControl -edit -sound audio1 $gPlayBackSlider;
// To display sound in a soundControl, there must first be a sound
// node in the scene. We'll create one and give it the name "ohNo".
// Note that the argument to the -file flag must be a path to a valid
// soundfile.
//
sound -file "ohNo.aiff" -name "ohNo";

// Create a sound control (named "soundScrubber")
// and have it display the sound associated with audio node "ohNo".
//
window;
frameLayout -lv false;
soundControl -width 600 -height 45 -sound ohNo
-displaySound true -waveform both soundScrubber;
showWindow;

// Now setup "soundScrubber" to actually scrub with
// mouse drags.
//
string $pressCmd = "soundControl -e -beginScrub soundScrubber";
string $releaseCmd = "soundControl -e -endScrub soundScrubber";

soundControl -e -pc $pressCmd -rc $releaseCmd soundScrubber;


Cheerz...
