Visualization loads 20 seconds later than Music
Feb 12th, 2010, 12:19am  
Hi Everybody,

I am making a music visualization application using processing. The thing is that it is quite high resolution (1440x900 at 30 fps) ... so when i run the application in Present mode on a Macbook pro, the music starts playing, but I see the visualization after about 20-30 seconds. Till that, the screen is gray and shows some text at the corner saying "Stop".

My question is:

1. How do I avoid this from happening? ... Is there a way for me to start showing the visualization only when the music starts playing?

2. I also want to add a start/loading screen, which shows some kind of loading animation while the music and the visualization load. Kind of like in flash.

3. Also, is there a way for me to execute the draw function or the visualization by using a keypress or mousepress?

1)
boolean playNow = false;
void setup(){
...
playNow = true;
}
void draw(){
if( playNow ){
startMusic();
playNow = false;
}
...
}

2)
That depends. How are you loading the music and data for the visualization? If you're doing it in setup(), no, it's not easy.

3)
boolean drawActivated = false;
void draw(){
if( !drawActivated ){ return; }
...
}
void mousePressed(){
drawActivated = true;
...
}
