Hi, if anyone could help me figure out why my bubble does not stop once y is greater than the height that would be great
Thanks in advance.
Bubble b;
void setup() {
size(600, 400);
b = new Bubble();
}
void draw() {
background(0);
b.display();
b.ascend();
b.top();
}
class Bubble {
float x;
float y;
float d;
Bubble() {
x = width/2;
y = height;
d = 100;
}
void display() {
fill(255);
ellipse(x, y, d, d);
}
void ascend() {
y = y - 5;
}
void top() {
if (y > height) {
y = height;
}
}
}

look at top()
the error is in this function
the top of the screen is 0, not height
check your if-clause

Hi,
Have a look a this link:
https://processing.org/tutorials/drawing/
It explains the coordinate system of processing pretty well =)

also the radius is 50, so it looks better when we wait until the ball completely left the screen
and also when it reappears, it reappears below the screen and slowly ascends
if (y < -53) {
y = height+59;
}

I understand it, I guess I just donβt know it very well haha. Hopefully it will come with time

Okay cool, and the below would also be correct Iβm pretty sure?
if (y < -50) {
y = height+50;
}
I know what you mean, 50
I think it looks slightly better with 53
Nevermind
