mouseClicked and if statement?

in Programming Questions • 11 months ago

I tried putting mouseClicked in an if-statement. such as

if(mouseClicked && x==1) {
      make a circle
      x++;
}
if(mouseClicked && x==2) {
      make another circle
      x++;
}

However, when I tried this it says there was an error with the void and boolean inside the if-statement. I cannot figure this out. Help!

I know mouseClicked in a void, but I thought it wouldn't matter? I tried casting it inside the if-statement like (boolean)mouseClicked, but that didn't work out.

Put those ifs in the mouseClicked() like so:

void mouseClicked() {
if (x==1) {
make_a_circle();
x++;
}
if (x==2) {
make_another_circle();
x++;
}
}

It's basically saying: "If mouse is clicked then do things".

Alternatively, use mousePressed instead of mouseClicked (although it's not the same thing) if you want to do it with your code.

I wanted to make it so that if the mouse is clicked, then make a circle for each time the mouse is clicked.

Wouldn't the function you gave me right there just draw x amount of circles once the mouse is clicked once??

Well, so would yours (if you used mousePressed) because these events is refreshed one time on every draw() iteration.

Nevertheless, if I'm getting you right, you want one circle every click, but not a bunch of them while the mouse is pressed down? If so, then:

void setup() {
size(500, 500);
background(0);
fill(255);
noStroke();
}
boolean down = false;
void draw() {
if (down)
ellipse(mouseX, mouseY, 20, 20);
down = false;
}
void mousePressed() {
down = true;
}

But I'm still pretty unsure about what you'd like to achieve, although I'm sure it's nothing complicated.

" it says there was an error with the void and boolean inside the if-statement"
In this case, it helps to show the real error message (copy/paste) and the full code.
