Click to resize an object
Jun 1st, 2006, 6:47pm  
Hi there,

I am new to programming and I have spent hours trying to figure out how to do the following mouse interaction in Processing. If anyone could give some guidance I would be really grateful.

Basically what I want is a simple box on screen, that re-sizes or changes location each time the mouse is pressed. Ideally the shape should animate between each new size/location. The locations could be random, or ideally specified as target coordinates.

The problem I am having is writing the code that checks the current location/size then moves the shape towards a new target.

If anyone has seen some code that does a similar thing that would be really helpful.

Many thanks in advance,
Windy

Code:

float bx, by;
float mx,my;

void setup () {
 
 size( 200, 200 );   
    
}

void draw ()
{
    background(125);
    bx = bx + (mx-bx) / 100.0;
    by = by + (my-by) / 100.0;
    rect ( bx, by, 10, 10 );
}


void mousePressed ()
{
    mx = mouseX;
    my = mouseY;
}
