MousePressed within specific dimensions

in General Discussion • Other • 11 months ago

How would I go about getting the function void mousePressed() to work only within a specific area. Like say the dimensions are 100, 100 and I want mousePressed to affect only the top right quarter of the area?

You use an if statement with mouseX and mouseY...

Code Example

void mousePressed() {
if (mouseX > width/2 && mouseY < height/2) {
// other code
}
}

So I wanted the mouse x specifications to work only between points (120, 0) and (240, 120)

but this code didn't work at all.

if (mouseX > 120 || mouseX <240 || mouseY < 120 ) {

if (skunk.isPlaying()) {

skunk.pause();}

else {skunk.play();}

if (player.isPlaying()) {

player.pause();}

}

help!

You used || instead of &&
Not the same thing...

if (mouseX < 120 || mouseY < 120) {

if (player.isPlaying()) {

player.pause();}

else{ player.play();}

if (skunk.isPlaying()) {

skunk.pause();}

}

if (mouseX < 240 && mouseX > 120 || mouseY < 120) {

if (skunk.isPlaying()) {

skunk.pause();}

else {skunk.play();}

if (player.isPlaying()) {

player.pause();}

}

this doesnt work either though, the areas I want to trigger the songs dont, while other seemingly random areas do..

You still use || in your test.
|| is a logical OR
&& is a logical AND

work only between points (120, 0) and (240, 120)

if (mouseX > 120 && mouseX < 240 &&
mouseY > 0 && mouseY < 120) {

void mouseMoved()

{

if (mouseX > 0 && mouseX < 120 &&

mouseY > 0 && mouseY < 120) {

if (player.pause()) {

fill(0);

rect(0,0,width/12,height/4);

fill(0);

rect(60,0,width/12,height/4);}

}

the message i get from this is 'cannot convert void to boolean'

Is there a way to make the rectangle have no fill when the mouse is moved over it ONLY when the song is paused?

if (player.pause()) {
cannot convert void to boolean
Looks like your pause() method is void, while you try to get a true / false condition out of it.
If player is an object of a class you made, you can change pause() to return a boolean value.
If that's a built-in object (Minim?), you use it wrongly, I suppose pause() is a command, not a status check.

I suppose

if (player.pause()) {

maybe it's

if (player.pause) {

if pause() really is a function / method in your class (and not a viariable) it must return boolean instead of nothing (void). Does it?

===========================================================================

I suppose when you say

player.pause();

player.play();

elsewhere in your Code
you could add there

isPlayerPlaying=true;

and

isPlayerPlaying=false;

(as global variable

boolean isPlayerPlaying=false;

)

---------------------------------------------------------------------------------------------------------------------------------------

And then here instead if

if (player.pause()) {

say

if (!isPlayerPlaying)

======================================================================

Remember that you can auto-format your code with ctrl-t.

======================================================================

To make a rect without filling use

noFill();

I hope this helps.

I'm not sure how to make this work :s

I am using minim, so will that make what I want to achieve impossible or am I just going about it the wrong way?

my full code is:

Minim minim;

AudioPlayer player;

AudioInput input;

AudioPlayer skunk;

AudioInput badger;

AudioPlayer re;

AudioInput mix;

void setup()

{

size(720, 480);

minim = new Minim(this);

player = minim.loadFile("heys.mp3");

input = minim.getLineIn();

minim = new Minim(this);

skunk = minim.loadFile("heartbreak.mp3");

badger = minim.getLineIn();

minim = new Minim(this);

re = minim.loadFile("breakbot.mp3");

mix = minim.getLineIn();

}

void mousePressed()

{

if (mouseX > 0 && mouseX < 120 &&

mouseY > 0 && mouseY < 120) {

fill(c1,0,c2);

rect(0,0,width/12,height/4);

fill(c2,0,c1);

rect(60,0,width/12,height/4);

if (player.isPlaying()) {

player.pause();

}

else{ player.play();}

if (skunk.isPlaying()) {

skunk.pause();}

}

if (mouseX > 120 && mouseX < 240 &&

mouseY > 0 && mouseY < 120) {

fill(c3,0,c4);

rect(120,0,width/12,height/4);

fill(c4,0,c3);

rect(180,0,width/12,height/4);

if (skunk.isPlaying()) {

skunk.pause();}

else {skunk.play();}

if (player.isPlaying()) {

player.pause();}

}

void mouseMoved()

{

if (mouseX > 0 && mouseX < 120 &&

mouseY > 0 && mouseY < 120) {

if (!isPlayerPlaying) {

noFill();

rect(0,0,width/12,height/4);

fill(0);

rect(60,0,width/12,height/4);}

}
