How to implement millis for timed action?

in Programming Questions • 1 month ago

Hi!

So I am trying to do this:

click icon

bell sounds

timer begins and

counts 15 minutes

at 15 minute mark

different bell sounds

I have this code, but I cannot get the timer to work or the second bell to sound in mouseReleased, and if I bump it up into void draw, all events happen at the same time -- (am brand new to this) Any help would be great - thank you!

int passedTime;
int savedTime15;
int totalTime15 = 5000; //(currently set for 5 second test)9000000;

void setup()

int savedTime15 = millis();

void draw()

int passedTime = millis() - savedTime15;
totalTime15 = millis() + 5000; //set for 5 second test

void mouseReleased()

{if (a.mouseReleased())
{player_open_bell = maxim.loadFile("start_bell.wav");
player_open_bell.stop();
player_open_bell.cue(0);
player_open_bell.play();
player_open_bell.setLooping(false);}
if ( a.mouseReleased() - passedTime >= totalTime15 )
{player_close_bell = maxim.loadFile("end_bell.wav");
player_close_bell.stop();
player_close_bell.cue(0);
player_close_bell.play();
player_close_bell.setLooping(false);
println( " 5 seconds have passed! " ); //test
savedTime15 = millis();}

mousePressed(), mouseReleased(), mouseClicked() and such are event callback functions.
You state that you want to change the bell sound playing after some time has passed.
However, you've put the whole code responsible to change sounds inside an event function.
And consequently, it's become bound to mouse clicks rather than a timer!

The only thing you'd wanna do there is checking whether some bell icon had been clicked.
At least that's my understanding from what you've told us, is it?

I don't have the means to run your code, since I don't have those files nor the library.
Nevertheless, I've done a template to give you an idea. Check it out:

static final String[] sounds = {
  "bell_00", "bell_01", "bell_02", "bell_03", "bell_04"
};

static final String EXT = ".wav";
static final int TIMER = 15*60*1000;

int idx;
boolean isPlayingNow;

void mouseClicked() {
  if (!isPlayingNow && wasBellIconClicked())
    thread("bellSoundThread");
}

boolean wasBellIconClicked() {
  return true;
}

void bellSoundThread() {
  isPlayingNow = true;

  while (isPlayingNow) {
    player = maxim.loadFile(sounds[idx] + EXT);
    player.play();

    delay(TIMER);

    player.stop();
    player.cue(0);

    if (++idx == sounds.length)   idx = 0;
  }
}

Ah ok, I must have misunderstood something I read, (I am looking through all the forums etc and am trying to piece stuff together - so many different ways to do things)

I'll try this out - thank you;-)

I'm looking at a GUI tester one of my classmates did and in the mousePressed he has his 'if' and 'print' statements. In class we were told to put stuff in the mouse functions --

But at any rate, I am having trouble with the template above trying to fit it into my code - will keep at it --- probably because I don't understand it all yet --

You can also do timers without using a separate thread.

int time, delayAmt=5000;
void setup(){
size(220,220);
time = millis() + delayAmt;
}
void draw(){
background(0);
if( millis() > time ){
background(255,0,0);
}
}
void mousePressed(){
time = millis() + delayAmt;
}

You should post your updated code, so we can have an idea where you're at by now.

Hi GoTo - I could not make it work with what was above, so it is back to my orig code - I have been trying to read more about millis etc - and have read that it has to be in draw, so, if I am reading that correctly, I should be trying to sort out a way to do that?

Is there anyway I can post my entire program or can we just do bits and pieces?

Thanks I will look at that - it looks easier;-)

There's a nice and simple Timer class here: http://www.learningprocessing.com/examples/chapter-10/example-10-5/

I often use it, and added a time() method to return the time passed since it started, means you can trigger lots of things with one timer by doing:

if (myTimer.time() > 2000) { do stuff }

Ah thank you - that looks much simpler - I will try that maybe -- can I only use that in draw?

Re: How to implement millis for timed action?

My template wasn't supposed to be a running program.
Rather a general idea on how you could implement it yourself.

One of the things I did was declaring an Array to store all sound's file names.
And that's exactly what your current code sorely lacks!

You use different variable names for each single thing.
Even though they could be grouped under the same label, b/c they represent the same type of object.

W/o organizing them under some Array or List or maybe even a class,
it's gonna be a pain to tame your code unfortunately.

Ah ok, I'll sort out an array - I am just at the beginning of this and I wanted to make sure all the parts worked before I tried to make it smaller - I'm trying to understand it all as I go along;-)
