Display something while an applet is loading

in General Discussion • Other • 5 months ago

Hi,

I have made a big applet which needs 20-30 seconds before displaying something.
I get all the data needed in the setup section. That is the reason why it takes a long time to show something.
I would like to display something that indicates to the users that the application is loading data during the setup.
An idea ?
I noticed that with some applets the java logo appears while the applet is loading. It would be a solution. With my applet the java logo never comes.

Thank you for your help.

boolean doDrawLoad=true;
void setup(){
size(220,220);
background(255,0,0);
} // Reaching this point updates the screen with what is drawn in setup().
void draw(){
if( doDrawLoad ){
// Load your data here.
// Simulating a long load with delay() - the only acceptable use of delay()!
delay(10000);
doDrawLoad=false;
} else {
// Draw like normal.
background(0,255,0);
}
}

A workaround is to show an opening screen on the first frame, load everything on the second frame and start the actual program on the third frame.

void draw() {
if (frameCount==1) {
// draw opening screen
} else if (frameCount==2) {
// load stuff
} else {
// your program
}
}

Another workaround is to use threads to load your stuff and only start the real program once everything is loaded.
