funkier functions that make you look smart
We can also use an exponential function, which starts off really slow and gradually moves faster and faster.
//----------------------------
// variables
float currY;
int currTime;
//----------------------------
void setup() {
// set up the applet
size(300, 300);
smooth();
frameRate(30);
// reset the animation independent variable (time)
currTime = 0;
// set the ball color
noStroke();
fill(#FF6F00);
}
//----------------------------
void draw() {
// clear the screen
background(0);
// move the ball
currY = move(currTime);
// draw the ball
ellipse(width/2, currY, 20, 20);
currTime++;
}
//----------------------------
void mousePressed() {
// reset the animation independent variable (time)
currTime = 0;
}
//----------------------------
float move(float x) {
return (pow(1.1, x) + 10);
}
Finally, we can try a logarithmic function, which starts off really fast and gradually moves slower and slower.
//----------------------------
float move(float x) {
return (50 * log(x) + 10);
}
Remember that with all of these functions, you can always add a coefficient or a constant term to scale or offset your output!
