Simple mouse clicked counter question

in Programming Questions • 10 months ago

I am trying to set up a code that will display the number 0 on the screen and increase the number by 1 every time the mouse is clicked.

my code so far is below , however I am not sure what i need to set this up correctly. Can anyone help? Thanks

Counter cntr;
int scr = 0;
//float xpos;
//float ypos;
void setup() {
size(500, 500);
cntr= new Counter();
}
void draw() {
background(255);
cntr.display();
if (mousePressed == true) {
scr++;
}
}
class Counter {
Counter() {
}
void display() {
text (""+scr, 250, 250);
}
}

I think a whole class just to store a simple counter is a lil' overblown!

Anyways, if you need some task to trigger every time a mouse is clicked, you gotta put your code inside callback function mousePressed(), rather than check global system variable mousePressed!

thanks, tht helped a lot. The new formatting + a string code i found on the forums did the trick!

And yes, the class is a little much :/ I was just trying to set it up tht way so i could be easier to put into a larger project later on.

here's my new code! Thanks Again!

Counter cntr;
int scr = 0;
//float xpos;
//float ypos;
void setup() {
size(500, 500);
cntr= new Counter();
}
void draw() {
background(255);
cntr.display();
cntr.MousePressed();
}
class Counter {
Counter() {
}
void display() {
noStroke();
textAlign(CENTER);
textSize(50);
fill(237, 28, 36);
text (""+begin(scr), 250, 250);
}
void MousePressed() {
if (mousePressed == true) {
scr++;
delay(200);
}
}
String begin(int a) {
String Buffer;
Buffer=nf(a, 1);
return(Buffer);
}
}

When I mentioned mousePressed(), I've meant a special one, which is of system callback type.
Just like the other callback types -> setup(), draw(), etc.
Those types don't work inside a class!

The way it is set there, it's just a normal method of it.
If you hold down a mouse button, the counter keeps increasing, rather than for each separate mouse click!

Another tip: Instead of using delay(), set desired frameRate(); inside setup() block.

Sorry for the mixup, i setup up a void mousePressed() and used f rameRate() instead of delay, and the code is working even better now. Thanks again for all your help and patience!
