Hey guys.
I have this sketch in which an ellipse follows the mouse. It has easing, but can anyone tell me how to put a straightforward speed limit on the ellipses movement?
thanks in advance.
//CODE:
float x, y;
float easing = 0.05;
PVector circle = new PVector(250, 250);
int radius = 300;
void setup() {
size(500, 500);
x = y = width/2;
noStroke();
smooth();
}
void draw () {
background(51);
fill(255);
ellipse(circle.x, circle.y, radius, radius);
PVector m = new PVector(mouseX, mouseY);
if (dist(m.x, m.y, circle.x, circle.y) > radius/2) {
m.sub(circle);
m.normalize();
m.mult(radius/2);
m.add(circle);
}
x = x + (m.x - x) * easing;
y = y + (m.y - y) * easing;
fill(255, 0, 0);
ellipse(x, y, 24, 24);
ellipse(m.x, m.y, 12, 12);
}
